20120239290
The present invention relates to an information processing apparatus, an information processing system, an information processing method and a bicycle map.
In recent years, bicycle racing called Cycle Sport has been popular both domestically and internationally, as one of sport activities. As types of bicycle racing, track racing, off-road racing and road racing have been known. Here, track racing known as keirin, sprint and so forth, is a race where racers run along a circular racing track. Off-load racing is a race where racers run on unpaved roads and slops of mountain forests using bicycles such as mountain bikes. Then, road racing is a race where racers run on paved roads over several dozen kilometers to several hundred kilometers. For example, stage race such as cycle road race hosted by Japan Bicyclist Club federation and Tour de France, is known as types of road racing. In addition, as another type of road racing, there is hill climbing held on uphill slopes over the entire route, using road bikes.
Cyclists who participate in these races include professionals entering races with prize money, semiprofessionals belonging to business organizations, amateurs, so called recreational cyclists, who make positive efforts to participate in races by doing daily training. In addition to the above-described cyclists who participate in official races, there are many general cyclists, for example, who commute to their office, enjoying cycling with a professional road bike, and who go for an outing to suburbs, enjoying long-distance cycling on holidays such as weekends.
For the above-described cyclists, it is important to find travel routes, which are fit for respective objects and allow the cyclists to do effective training and delightful cycling. For example, a cyclist doing training to participate in road racing may want to run on paved roads in the suburbs. This is why such roads allow continuous running over a long distance more than several kilometers, although the cyclist could not wish to continue to run over several dozen kilometers to several hundred kilometers. Meanwhile, a cyclist who enjoys delightful cycling on holidays may want to run on flat roads which are not crowded and noisy, enjoying beautiful scenery and clean air as possible.
For example, when a cyclist seeks a comfortable cycling road in an unfamiliar place, he may want to search for a local famous cycling road frequently used by the local cyclists, if possible. Therefore, conventionally, cyclists have guessed appropriate travel routes on maps such as a road map and tried the roads. Also cyclists have received information from acquaintances and obtained information via media such as Internet and so forth. However, collecting information through these methods has limitations, and more comfortable travel routes are likely to be missed. Therefore, there is an increasing demand for more extensively collecting information to meet the requests from cyclists. Here, various technologies for searching appropriate travel routes have been known, although they are not targeted for bicycles but for cars (see, for example, Patent Literatures 1 to 5).
Patent Literature 1 discloses a car route guidance apparatus configured to use past driving conditions. A technical feature of the apparatus is to calculate a degree of familiarity about roads according to the number of runs on the roads to a destination in the past, and performs route search by preferentially selecting a road familiar to the driver.
In addition, Patent Literature 2 discloses a car navigation apparatus configured to accumulate the running paths of the car as path data to use for route search.
A technical feature of the apparatus is to search for the route between two points inputted based on track data indicating the number of times cars pass crossovers or links and so forth.
Moreover, Patent Literature 3 discloses a navigation apparatus configured to provide guidance using the past running history of a car (for example, the number of runs of a car within a predetermined range). A technical feature of the apparatus is to determine the frequency of running based on the past running history to provide predefined navigation according to the frequency.
Moreover, Patent Literature 4 discloses an information creating system configured to create information about bypass routes frequently used by the local users. A technical feature of the apparatus is to acquire running track information from a plurality of cars via communication means, and calculate, for each link, an amount of running of the local cars and an amount of running of the cars from the outside, so that the route frequently used by the local users is extracted among the routes to the destination.
Furthermore, Patent literature 5 discloses a map data distribution apparatus configured to create map data by updating blocks including a searched car route. A technical feature of the apparatus is to distribute, to a navigation apparatus, updated map data on the block which should be updated, among blocks including the route having the start point and the end point of the car.
However, the above-described technologies disclosed in Patent Literatures 1 to 5 intend to search travel routes for cars but not for bicycles, and therefore cannot always provide travel route search which successfully satisfies the demands from cyclists. It is because a route is not always perfect for a cyclist, which allows the cyclist to move from the departure place to the destination by the most direct way or in the shortest period of time. For example, many cyclists may want to avoid from running on busy roads because such roads pose danger to cyclists. In addition, there may be a need to search for travel routes unique to cyclists. For example, a cyclist wants to search for a travel route including a route for running on a slow ascent for training to the destination and a different route to return to the departure point while the cyclist enjoys the view.
The present invention was accomplished in view of the above-described circumferences. It is therefore an object of the present invention to provide an information processing apparatus, an information processing method, an information processing system and a bicycle map that can solve the above-described problems.
To solve the above-described problems, the information processing apparatus according to the present invention includes: a first acquiring part configured to acquire bicycle positional information regarding a bicycle being running, by use of a positioning system; a second acquiring part configured to acquire bicycle-related information regarding the bicycle when the bicycle positional information is acquired; a travel route information creating part configured to create travel route information obtained by associating the bicycle positional information with the bicycle-related information; a storage part configured to store the travel route information in a storage device; a merging part configured to merge pieces of travel route information created by a same information processing apparatus or different information processing apparatuses; and an output part configured to output travel route information merged by the merging part.

Now, an information processing apparatus and an information processing method using the information processing apparatus will be described in detail with reference to the drawings. The information processing apparatus is mounted on a bicycle and creates a bicycle-dedicated travel map by acquiring: information regarding the operator of the bicycle (cyclist) (for example, profile information including physical features such as height and weight, athletic capability, the results of the bicycle races that the cyclist obtained in the past; and the types of bicycles used by the cyclist); information regarding the running conditions of the bicycle (for example, the speeds and the positions of the bicycle); the other information regarding the bicycle; environmental information when the bicycle is running (for example, the slope of the road, the temperature and the humidity when the bicycle is running); and so forth.

[Configuration of Information Processing Apparatus]
As shown in
The speed sensor 101 is a device to measure the traveling speed of the bicycle 1. The speed sensor 101 calculates the speed of the bicycle 1 per unit time by use of, for example, a magnet fixed to a spoke and so forth in a wheel of the bicycle 1 and a magnet detector mounted on the chain stay 1L and so forth to calculate the moving distance of the bicycle 1 every period of time the magnet passes the magnet detector based on the circumferential length of the wheel.
The cadence sensor 102 is a device to measure the number of rotations of the pedal 1R of the bicycle 1 per unit time. The cadence sensor 102 measures the number of rotations of the pedal 1R per unit time by use of, for example, a magnet mounted on the pedal 1R and a magnet detector mounted on the chain stay 1L and so forth. That is, recreational cyclists are greatly interested in the running of a professional cyclist using the bicycle 1, represented by the cadence (the number of rotations of the crank per minute). For example, it is valuable for recreational cyclists to know how fast and slow a professional cyclist rotates the pedal 1R of the bicycle 1 when he pedals. Therefore, with the information processing apparatus 2 according to the present embodiment, it is possible to easily check on a map, the cadences of other cyclists, including a professional cyclist, for running on the same route.
The heartbeat sensor 103 is a device to measure the heart rate of the cyclist of the bicycle 1. For example, the heartbeat sensor 103 measures the heart rate per unit time by being fixed to the chest of the cyclist and measuring electrocardiogram with electrodes.
The slope sensor 104 is a device to calculate the average slope of the travel route when the bicycle 1 runs in a given period of time. Here, the slope sensor 104 does not always need to be used. For example, the average slope may be calculated based on a distance and an altitude difference (a vertical drop), by calculating the moving distance for a given period of time using the GPS sensor 109 and so forth, and calculating the altitude difference for the given period of time required for the movement, based on the altitude information calculated by the atmospheric pressure 105. In addition, the slope sensor 104 may be built in the information processing apparatus 2, or directly mounted on the bicycle 1.
The atmospheric pressure sensor 105 is a device to measure the atmospheric pressure around the bicycle 1. With the present embodiment, the atmospheric pressure sensor 104 or the control device 200 calculates the altitude of the bicycle 1 based on the atmospheric pressure measured by the atmospheric pressure sensor 104. Here, the atmospheric pressure sensor 105 may be built in the information processing apparatus 2, or directly mounted on the bicycle 1. In addition, instead of the atmospheric pressure sensor 105, the GPS sensor 110 may be used to acquire data on the altitude, or three-dimensional map information including altitude information may be used as map information.
The wind speed sensor 106 is a device to measure the speed of the bicycle 1 relative to the air around the bicycle 1. The wind speed sensor 106 calculates the wind speed by measuring the speed at which the air moves relative to the bicycle 1 using an air flow sensor, a propeller or a microphone. The wind speed sensor 106 may be built in the information processing apparatus 2, or directly mounted on the bicycle 1.
The temperature sensor 107 is a device to measure the temperature around the bicycle 1 (for example, the temperature at which the bicycle 1 stops and the temperature at which the bicycle 1 is running). The temperature sensor 107 may be built in the information processing apparatus 2, or directly mounted on the bicycle 1.
The humidity sensor 108 is a device to measure the humidity around the bicycle 1 (for example, the humidity at which the bicycle 1 stops and the humidity at which the bicycle 1 is running). The humidity sensor 108 may be built in the information processing apparatus 2, or directly mounted on the bicycle 1.
The GPS sensor 109 is a positioning system to measure positional information on the bicycle 1. The GPS sensor 109 may also acquire information about the current time and the traveling direction of the bicycle 1 as well as the positional information via a GPS antenna (not shown). The GPS sensor 109 may be built in the information processing apparatus 2, or directly mounted on the bicycle 1.
The acceleration sensor 110 is a device to measure a change in three-dimensional position due to a change in acceleration of the bicycle 1. Based on information about the measured acceleration, it is possible to determine the road surface condition and curve characteristics. For example, when the acceleration fluctuates in the vertical direction for a certain period of time, it can be determined that the road surface condition is poor, and, when the acceleration is a certain value or higher, it can be determined that the route includes a dirt road. In addition, when the acceleration instantaneously and significantly fluctuates in the vertical direction, it can be determine that it is hard to run on the road by the bicycle 1 or there is a risk of fall on the road because the road surface is quite bumpy or there is the cover of a drainage conduit and so forth. In this way, by using the acceleration sensor 110, it is possible to add road surface conditions and dangerous spots to a bicycle map displayed on the monitor 400. Moreover, by using the acceleration sensor 110, alarm or guidance may be displayed on the monitor 400, or sound may be outputted from the speaker 500 in running, depending on road surface conditions. The acceleration sensor 110 may be built in the information processing apparatus 2, or directly mounted on the bicycle 1.
The power sensor 111 is a device which is built in the crank or the rear wheel hub of the bicycle 1 to detect output of the bicycle 1. A typical power sensor 111 is a power meter. A general power meter can measure the force applied to a sprocket and display the measurement result on a cycle computer (not shown) or the monitor 400. Such a sensor has drawn attention of many cyclists including professional, semiprofessional and recreational cyclists. By using the power sensor 111, the information processing apparatus 2 according to the present embodiment can visually display on a map a travel route with a slope which necessarily applies load to the cyclist. Besides this, the information processing apparatus 2 can visually display a route even constituting flat roads, which applies load to the legs of the cyclist running as fast as he can (for example, a route which includes the road frequently used for training and applies great load to the legs of many cyclists).
As described above, the sensor group 100 in the information processing apparatus 2 according to the present embodiment is configured to be able to measure various data using various sensors. Here, in order to acquire and calculate the above-described various data, it does not necessarily need to use the data acquired by each single sensor. For example, data obtained by combining the data acquired by a plurality of sensors and calculating from that data, or the data acquired by a sensor in another information processing apparatus 2 may be used by inputting the data from the communication I/F 600 and so forth.
Various data measured by the sensor group 100 is stored in the information processing apparatus 2, and then subjected to various processing such as computation and output. As shown in
The memory 202 may be an internal storage device such as a flash memory, a RAM, a ROM and a hard disk drive, or an external nonvolatile memory such as a USB memory and a flash memory card. In the information processing apparatus 2 according to the present embodiment, the memory 202 temporarily or permanently stores the data and so forth acquired by the sensor group 100 and computed by the CPU 201. Also in the information processing apparatus 2, additional information such as map information is stored in the memory 202. The stored additional information is associated with the acquired and computed data to create a bicycle map. Then, the monitor 400 may display the created bicycle map.
The image control circuit 203 controls the monitor 400 including such as a liquid crystal screen according to a command from the CPU 201 to display an image corresponding to the command on the screen. The audio control circuit 204 generates an audio signal according to a command from the CPU 201 and allows the speaker 500 to output the voice signal.
The communication control circuit 205 can output (transmit) various data stored in the memory 202 to the external device via the communication I/F 600, according to a command from the CPU 201. In addition, the communication control circuit 205 may receive data from the external device via the communication I/F 600 and store the data in the memory 202. Here, the communication I/F 600 may be realized by various antennas to connect a network such as Internet for radio communication, or may be realized by a communication interface to connect to a LAN cable and so forth for cable communication.
In addition, the input I/F 300 is connected to the control device 200 via the bus 206. The input I/F 300 has a button 301 used by a cyclist and so forth to instruct to start/end data measurement and so forth, and an operation keys 302 equivalent to keys on a keyboard, a cellular phone and so forth, which allow the cyclist to input characters. In addition to the button 301 and the operation keys 302, the input I/F 300 also has a pointing device for various operations, such as a track ball and a joy stick. Otherwise, the input I/F 300 may be formed by a touch panel and share a screen with the monitor 400, instead of the button 301 and the operation keys 302, or together with them.
The running information acquiring part 11 functions as means for acquiring running information including the positional information on the bicycle 1, using the control device 200 for data processing, including analyzing data such as the data measured by the sensor group 100 constituting the speed sensor 101, the cadence sensor 102, the wind speed sensor 106, the GPS sensor 109 and the acceleration sensor 110, and the data inputted by operating the input I/F 300. In addition, the cyclist information acquiring part 12 functions as means for acquiring information on the cyclist of the bicycle 1 (physical information and profile information on the cyclist described later), using the control device 200 for processing data such as the data measured by the heartbeat sensor 103 in the sensor group 100, and the data inputted by operating the input I/F 300. The environmental information acquiring part 13 functions as means for acquiring information on the external environment of the bicycle 1 while running, by using the control device 200 for processing data such as the data measured by the slope sensor 104, the atmospheric pressure sensor 105, the temperature sensor 107 and the humidity sensor 108 constituting the sensor group 100, and the data inputted by operating the input I/F 300.
The storage part 20 can temporarily or permanently store various data acquired by the running information acquiring part 11, the cyclist information acquiring part 12 and the environmental information acquiring part 13. The storage part 20 also can store the intermediate data on the computation by the travel route information creating part 30 and the travel route information merging part 40, the created travel route information, map information associated with the travel route information, and various information inputted by the cyclist through the data input part 80. Here, the function of the storage part 20 is realized by the memory 202 and so forth shown in
The travel route information creating part 30 is a unit realized by the control apparatus 200 and so forth, and has a function to create travel route information on the bicycle 1 by performing arithmetic processing on various data acquired by the sensor group 100. That is, the travel route information creating part 30 creates travel route information by associating the information regarding the bicycle 1 acquired by the information acquiring unit 10, including the running information, the cyclist information and the environmental information while the bicycle 1 is running, with the travel route information including the positional information on the bicycle 1 measured by the GPS sensor 109 at regular time intervals.
The travel route information merging part 40 is a unit realized by the control device 200 and so forth, and merges one or more pieces of travel route information created by the travel route information creating part 30 with another travel route information acquired from another information processing apparatus and so forth to make integrated travel route information.
The bicycle map generating part 50 is a unit realized by the control device 200 and so forth, and creates a bicycle map by associating the travel route information generated by the travel route information creating part 30 or the travel route information merging part 40 with map information stored in the storage part 20.
The bicycle map display part 60 has a function to display, on the monitor 400, various information including a bicycle map created using the control device 200 to process the various data acquired by the group sensor 100, and a function to output various audio data such as operation information, operation sound, beep sound and so forth from the speaker 500. In this case, the input I/F 300 may switch displaying pieces of information such as various information acquired by the running information acquiring part 11, the cyclist information acquiring part 12 and the environmental information acquiring part 13; travel route information acquired by the travel route information creating part 30 and the travel route information merging part 40; a bicycle map created by the bicycle map creating part 50; cyclist information used to create the map; map information; and setting information on the information processing apparatus 2.
The data output part 70 allows data communication between an external device (not shown) and the information processing apparatus 2 to transmit and receive various data. An example of the data output part 70 is shown in
The data input part 80 has a function to allow the cyclist and so forth to input operating information to, for example, start and stop various data measurement and switch display of output information on the monitor, via the input I/F 300 such as the button 301 and the operation keys 302. The data input part 80 also has a function to input additional information, including cyclist's information on the physical feature and the results of the past races and predetermined setting information on the information processing apparatus 2, via the above-described input I/F 300.
[Creation of Bicycle Map by Information Processing Apparatus]
Next, steps of creating a bicycle map using the above-described information processing apparatus 2 will be explained in detail with reference to the drawings.
First, the cyclist operates the input I/F 300 in the information processing apparatus 2 to initialize (reset) the information processing apparatus 2 to prepare to create a new bicycle map (step S1). This reset of the information processing apparatus 2 changes the initial value of part of information temporarily accumulated in the storage part 20 to zero or a predetermined value, which is accumulated from the start to the end of measurement to create travel route information.
After resetting the storage part 20 in step S1, the information processing apparatus 2 determines whether or not there is a command (for example, by pushing the button 301) to start data measurement via the operation of the input I/F 300. As a result, determining that there is a command to start data measurement (Yes), the information processing apparatus 2 performs processing in step S3. On the other hand, when there is no command to start data measurement, the information processing apparatus 2 waits for a command to start data measurement. Here, data measurement may automatically start by reset processing (step S1) or automatically start at the time the bicycle 1 starts moving. In addition, when there is no command to start data measurement from the cyclist and so forth over a predetermined period of time (e.g., 60 seconds or longer) after the reset processing in the information processing apparatus 2, the information processing apparatus 2 may change the mode to a power-saving mode such as a sleep mode.
In step S3, the running information acquiring part 11 and the environmental information acquiring part 13 which are realized by the sensor group 100 and so forth acquire information created with running of the bicycle 1 (running information) and information about the external environment when the bicycle 1 is running (environmental information) (step S3). With the present embodiment, the running information acquiring part 11 acquires, for example, the following information at regular time intervals (e.g., per one second) and stores the information in the storage part 20.
In addition, with the present embodiment, the cyclist information acquiring part 12 acquires the following information at regular time intervals (e.g., per second) and stores the information in the storage part 20.
Moreover, with the present embodiment, the environmental information acquiring part 13 acquires the following information at regular time intervals (e.g., per second) and stores the information in the storage part 20.
Next, the information processing apparatus 2 determines whether or not there is a command (for example, by pushing the button 301) to end the data measurement by the operation of the input I/F 300 (step S4). As a result, when receiving a command to end the data measurement (Yes), the data processing apparatus 2 performs processing in step S5. On the other hand, when not receiving a command to end the data measurement, the information processing apparatus 2 continues running information acquiring processing (step S3). Here, with the present embodiment, the input I/F 300 has one button (button 301) which serves as the start button and the stop button. However, the input I/F 300 may have a plurality of buttons and uses respective buttons as the start button and the stop button.
Next, in step S5, the cyclist of the bicycle 1 operates the input I/F 300 to input profile information on the cyclist by him/herself, so that the information processing apparatus acquires the profile information. Here, the profile information includes various information, such as personal physical information including age, gender, height and weight, and athletic capability; ranking information including professional cyclists, recreational cyclists and beginners; record information on the past races in which the cyclist participated (for example, the records in a famous race); the name of the team to which the cyclist belongs; information about the bicycle on which the cyclist rides; years of experience; the annual mileage; days of the week, seasons and the time zone for cycling. The athletic capability includes the cardiopulmonary function, the staying power, and the muscle strength of the cyclist. Here, with the present embodiment, the profile information is acquired after the information generated with running of the bicycle 1 has been acquired in step S3. However, the profile information may be acquired before the bicycle starts running, or the data having been inputted from a different apparatus on another date and time may be inputted to the information processing apparatus 2.
Next, the travel route information creating part 30 analyzes the running information acquired in step S3 (for example, the hourly positional information on the bicycle 1 acquired by the GPS sensor) to generate travel route information on the bicycle 1 (step S6). That is, the travel route information creating part 30 can acquire, at regular time intervals, latitude and longitude information on the position to which the bicycle 1 moves over a certain period of time, based on the information acquired by the GPS sensor 109, and analyzes this latitude and longitude information. Here, with the present embodiment, the travel route information is created in association with the profile information on the cyclist acquired in step S5 and the cyclist information and the environmental information acquired as well as the running information in step S3. Then, the travel route information creating part 30 stores created travel route information in the storage part 20.
Now, details of processing for creating travel route information shown in step S6 will be described.
The travel route information creating part 30, first, reads GPS information for a certain section measured in step S3, from the storage part 20, and performs processing for subdividing the GPS information into sections (step S61). Now, details of processing for dividing into sections will be described.
The GPS information for a certain section which the travel route information creating part 30 reads from the storage part 20 may has a length of several meters or a wide length of several hundred kilometers. Therefore, in order to create more accurate travel route information, it is necessary to divide the travel route into each certain level of small area. With the present embodiment, for example, a travel route is divided according to the latitude and longitude information. For example, when a travel route passes the point of the latitude of 35 degrees and 40 minutes, and the longitude of 139 degrees and 46 minutes, an area tag (35, 139) is created, and the travel route with the area tag (35, 139) is defined as one section.
In this way, even if a travel route spans all over the world, it is possible to define a section with an appropriate size by dividing the travel route into sections with latitude and longitude tags as described above. By this means, it is possible to create travel route information for each of a plurality of divided sections even if a travel route is long, and therefore significantly reduce the load on the information processing apparatus 2 for one processing. Here, as boundaries used for dividing a travel route into sections, administrative boundaries such as countries, states, prefectures, and municipalities, may be adopted in addition to latitudes and longitudes. Moreover, by dividing latitudes and longitudes to decimal places, more finely-divided sections may be obtained.
Next, the following steps are performed for each section divided by the section-dividing processing in step S61. With the present embodiment, the following steps are performed on sections in the order from the section indicated by the area tag (36, 138).
That is, after the section-dividing processing in step S61, the information processing apparatus 2 determines whether or not there has been another travel route information in the area indicated by the area tag (36, 138), based on whether or not the travel route information on this area has always been stored in the storage part 20 (step S62).
Here, as described above, in the case shown in
Step S63 is executed when the result of the area determination in step S62 is negative “No”, and therefore new travel route information is created. That is, in this case, since any different route from the route in the same area is not stored in the storage part 20, new travel route information is created by associating the travel route 81 with running count information (the count (the number of times) is 1 because the travel route 81 is newly created this time).
Meanwhile, in step S64, merging processing is performed when it is determined that the result of the area determination is positive “Yes” in step S62. That is, in step S64, first, the travel route 82 accumulated in the storage part 20 in advance is read, and then compared with the new additional travel route 81 with respect to latitude and longitude positional information to determine whether the travel route 82 and the travel route 81 are the same or not, whether or not they branch/join on the way, and so forth. To be more specific, for example, all the sampling points are compared between the travel routes, and, when there are a plurality of sampling points having latitude and longitude positional information closer to one another than a predetermined threshold, it is determined whether or not the travel routes are the same based on the number of sampling points closer to one another. In this case, if there is a branch or a junction on the way, the branch or the junction is considered a new divided point, and therefore, the travel route is more finely divided into sections.
Here, with the present embodiment, taking into consideration of a difference in the traveling direction, it is determined to create different travel routes to create travel route information. This is why, differently from driving a car, the load on the cyclist is greatly influenced by whether the travel route ascends or descends. For example, the heart rate of the cyclist is higher and the speed of the bicycle is lower in a case in which the travel route ascends than in a case in which the travel route descends. Head wind more greatly affects the load on the cyclist. Therefore, if data on an ascending travel route and data on a descending travel route are simply merged into one, the average value between them is obtained. As a result of this, a difference between them, which is characteristic information on the travel routes with the slope could be cancelled. Therefore, with the present embodiment, the running information acquiring part 11 realized by the GPS sensor 109 and so forth acquires information on the traveling direction of the bicycle 1, and creates travel route information in a format that allows the travel route information to be classified based on the acquired traveling direction information. Here, with the present embodiment, for even one road, both the travel route in the forward direction and the travel route in the backward direction are determined taking into consideration the traveling directions as described above. However, similar processing without taking into consideration the traveling directions is possible.
Moreover, in the merging processing in the step 64, in order to create travel route information for each section, bicycle-related information is merged. The bicycle-related information may be, for example, averaged or grouped as described later, for each sampling point or each section, and may include information of the average speed at the corresponding sampling points and the level distribution in the section.
In addition, the accuracy of information on a three-dimensional change in position of the bicycle 1 obtained by the acceleration sensor 110 is improved because the number of samples is increased by merging and averaging. Then, it is possible to accurately tag travel route information with information about road conditions such as dirt and freeze, and also accurately provide POI (point of interest) information regarding caving points on the road and so forth as travel route information. Here, when the information regarding the bicycle 1 significantly changes in one section, the section may be divided into two or more sections.
After a new route is created in step S63, or after the merging processing in step S64 and adding running count information in step S65, the resulting information is saved in the storage part 20 (step S66). Then, it is determined whether or not the above-described processing is performed on all the sections (step S67). As a result, if the processing on all the divided sections has been completed (Yes), the processing ends. On the other hand, when the processing on all the sections has not been finished yet (No), the step returns to step S62 and the above-described processing is repeated. That is, with the present embodiment, for example, the first section divided in the first loop is processed, and subsequent sections are processed in subsequent loops in turn. For example, there are three sections with the area tags (36, 138), (36, 139), and (36, 139) respectively, loop processing is performed three times in turn from the area tag (36, 138).
Next, the travel route information merging part 40 performs processing for merging (integrating) pieces of travel route information which are acquired by the travel route information creating part 30 and stored in the storage part 20 (step S7). The pieces of travel route information referred here may be acquired from a plurality of cyclists, or acquired from one cyclist more than once. In addition, pieces of travel route information are not limited as long as they are stored in the storage part 20 by the time of merging processing, or may be created by a different information processing apparatus and then inputted in the information processing apparatus 2.
Next, details of processing for merging travel route information (step S7) will be explained.
First, the area targeted for processing for merging travel route information is fixed (step S71). Here, with the present embodiment, the target areas are respective rectangle areas (box areas divided by latitude and longitude lines) including the travel route over which the bicycle 1 runs from when the start button is pushed until the stop button is pushed as described above, and indicated by four area tags (36, 138), (36, 139), (35, 138) and (35, 139), respectively.
Here, method of fixing target areas is not limited to the above-described method, but another method is possible. For example, the positional information at the time of merging processing is acquired from the positional information which can be obtained by the GPS sensor (that is, current position is acquired), and then, one or more neighboring areas including the current position may be fixed as target areas. In addition, target areas may include a positional coordinate inputted by the cyclist using the input I/F 300. Otherwise, an area in a map which is obtained by displaying the map on the monitor 400 and scrolling and scaling the map using the input I/F 300, may be fixed as a targeted area.
Next, the information processing apparatus 2 reads all the routes in the target area (travel route information) fixed in step S71, from the storage part 20 (step S72). At this time, each travel route information is read, including pieces of latitude and longitude information indicative of a travel route, running count information indicative of the number of times of running on the route, and so forth. In this case, information to be read may include not only information acquired by each sensor, but also information acquired by the information processing apparatus 2 in the past and information merged with the information acquired by another information processing apparatus. That is, for example, for each sampling point, or section, the averaged slope, altitude, speed, cadence, heart rate, power and wind speed, and the grouped physical information such as age and level are read. In addition to these, other information may be read, for example, road condition information such as a dirty or freezing state, which is obtained by the acceleration sensor 110 and improved in its accuracy by merging processing, and POI (point of interest) information such as information on caving points on the road surface.
Then, the information processing apparatus 2 converts the read travel route information into XML text data (step S73). Here, also the running count information on each travel route is embedded in one XML tag and converted into XML text data. The information processing apparatus 2 saves the above-described converted text data in the storage part 20 (step S74). Here, with the present embodiment, although travel route information is used as text data, the data format is not limited to text as long as information can be added to and changed from, like text data.
The information processing apparatus 2 outputs and displays the travel route information having been subjected to the merging processing on a monitor screen and so forth by use of the bicycle map display part 60. In this case, the bicycle map display part 60 displays the merged travel route information by superimposing the merged travel route information on the map information stored in advance in the storage part 20.
Next, the information processing apparatus 2 detects the tag of running count information from the read XML data (step S82), and displays the travel route information on the screen, with different colors and so forth, depending on the number of times of runs (step S83). For example, when travel routes are displayed in red, the transparency may be changed depending on the number of times of runs. In this case, unused travel routes may be displayed in colors, for example, the colors of the displayed map information as they are, or may not be displayed. For example, the transparency may be changed in stages such that when the number of times of runs is 100 or more, the transparency is 0%; when the number of times of runs is 50 to 99, the transparency is 50%; and when the number of times of runs is one, the transparency is 99%. By this means, it is possible to display travel routes used for running a greater number of times in an opaque color, and therefore help the user of the information processing apparatus 2 easily and quickly acquire appropriate information.
In addition to changing the display color depending on the number of times of runs, another configuration is possible where the display color is changed depending on the average moving speed of the bicycle 1 acquired by the speed sensor 101. For example, when travel routes are displayed in red, the display color is changed by changing the transparency depending on the average speed. For example, travel routes are displayed with changing the transparency of a color in stages such that when the average speed is 40 km/h or higher, the transparency is 0%; when the average speed is 20 km/h to 40 km/h, the transparency is 50%; and when the average speed is lower than 20 km/h, the transparency is 99%. By this means, it is possible to display travel routes available for high-speed running in an opaque color, and therefore help the user of the information processing apparatus 2 easily and quickly acquire appropriate information.
In addition, the display color of travel routes may be changed using the output of the bicycle 1 acquired by the power sensor 111 such that the greater the output of the bicycle 1 is, the more opaque the display color is, by changing the transparency of the color in stages. By this means, it is possible to display travel routes which are hard on the legs of the cyclist in an opaque color, and therefore help the user of the information processing apparatus 2 easily and quickly acquire appropriate information.
Moreover, the display color of travel routes may be changed depending on the heart date of the cyclist of the bicycle 1 acquired by the heartbeat sensor 103. For example, the display color may be changed by changing the transparency in stages such that the higher the heart rate is, the more opaque the color is. By this means, it is possible to display a travel route, for example, which puts physical strain on cyclists, in an opaque color, and therefore help the user of the information processing apparatus 2 easily and quickly acquire appropriate information.
Moreover, the display color of travel routes may be changed depending on the average slope of the travel routes for the bicycle 1 acquired by the slope sensor 104. For example, the display color is changed by changing the transparency in stages such that the greater the average slope is, the more opaque the color is. By this means, for example, the travel route hard on the legs of the cyclist due to an ascending slope, which cannot be determined only based on the output of the power sensor 111, is displayed in an opaque color. Therefore, it is possible to help the user of the information processing apparatus 2 easily and quickly acquire appropriate information.
Moreover, the display color of travel routes may be changed depending on the atmospheric pressure around the bicycle 1 acquired by the atmospheric pressure sensor 105, and the altitude calculated based on the atmospheric pressure. For example, the display color is changed by changing the transparency in stages such that the higher the atmospheric pressure is, the more opaque the color is. By this means, it is possible to know a difference between running states due to a difference in altitude, and therefore help the user of the information processing apparatus 2 easily and quickly acquire appropriate information.
In addition, the display color of travel routes may be changed depending on the wind speed relative to the bicycle 1, which is acquired by the wind speed sensor 106. For example, the display color is changed by changing the transparency in stages such that the higher the wind speed is, the more opaque the color is. By this means, it is possible to display a local change in the wind speed where, for example, the speed increases depending on building conditions, and therefore help the user of the information processing apparatus 2 easily and quickly acquire appropriate information.
Moreover, the display color of travel routes may be changed depending on the temperature around the bicycle 1, which is acquired by the temperature sensor 107. For example, the display color is changed by changing the transparency in stages such that the higher the temperature is, the more opaque the color is. By this means, it is possible to display a change in the temperature in, for example, a place where the temperature increases due to direct sunlight and a place where the temperature decreases due to shade. Therefore, it is possible to help the user of the information processing apparatus 2 easily and quickly acquire appropriate information.
Moreover, the display color of travel routes may be changed depending on the humidity around the bicycle 1 acquired by the humidity sensor 108. For example, the display color is changed by changing the transparency in stages such that the higher the humidity is, the more opaque the color is. By this means, it is possible to determine the sensory temperature based on, for example, the temperature and the humidity, and therefore it is possible to help the user of the information processing apparatus 2 easily and quickly acquire appropriate information.
Moreover, in addition to changing the transparency of the display color, which is a single color such as red as described above, another configuration is possible where a plurality of colors are used and the display color is changed depending on the number of times of runs, or a combination is possible where changing the transparency is applied to the above-described configurations.
Furthermore, the display color of travel routes may be changed depending on the positional information and the current time acquired by the GPS sensor 109. For example, the display color is changed by time zones such as before noon, afternoon and night. By this means, it is possible to display the travel distance, the running speed and so forth for each time zone, and therefore help the user of the information processing apparatus 2 easily and quickly acquire appropriate information.
Furthermore, by associating the cyclist's profile information with travel routes, it is possible to display travel route information corresponding to each physical information such as height and weight. In this case, for example, it is possible to easily and quickly know what travel route is selected by persons similar to the cyclist in physique and age.
Here, by acquiring the above-described profile information as travel route information, the cyclist can run the bicycle 1 while displaying a travel route in more detail, which is suitable for the cyclist. By this means, for example, the cyclist can do more adequate training. In addition, by acquiring travel route information on a plurality of other cyclists, the cyclist can compare the athletic capabilities and the travel routes between the cyclist and other persons, and therefore easily make a plan for travel routes. Moreover, by acquiring pieces of travel route information on one cyclist, the cyclist can compare between the cyclist's own records, and this may increase the cyclist's motivation for training.
Moreover, cyclists tend to select comfortable travel routes and adequate travel routes fit for their purposes, and this inevitably leads to increase the number of times those travel routes are used. Thus, with the information processing apparatus 2 according to the present embodiment, the travel route easy for the cyclist of the bicycle 1 is displayed, for example, in an opaque red with the transparency of zero or approximately zero on the map. Therefore, it can be understood that this travel route in an opaque red is generally “easy for cyclists to run.” In addition, it is possible to collect information on not only one cyclist but also a plurality of cyclists, and therefore generalize the definition of “a road easy to run” and improve accuracy by combining information on a plurality of cyclists.
Next, the information processing apparatus 2 determines whether or not to continue a series of processing from data measurement to display of travel routes described above (step S9). As a result, when the processing is continued (Yes), it is determined whether or not to reset the information processing apparatus 2 (step 10), and, when the information processing apparatus 2 is reset (Yes), the step returns to step S1, and, on the other hand, when the information processing apparatus 2 is not reset (No), the step returns to step S2.
As described above, the information processing apparatus 2 according to Embodiment 1 can create and output travel route information obtained by associating bicycle travel route map information with bicycle information, cyclist information, external environmental information and so forth when the bicycle is running. By this means, the cyclist can visually recognize, for example, what travel route the persons prefer who have the same physical features such as physique and age and athletic capability as the cyclist. Therefore, it is possible to easily and quickly display information fit for a purpose.
In addition, the data from the information processing apparatus 2 mounted on the bicycle 1 may be saved in a computer 6 such as a personal computer, via a network 4 (communication network) such as Internet or a removable and portable storage medium 5 such as a USB memory, and then uploaded from the computer 6 to the information processing server 3. In this case, the information processing apparatus 2 downloads new data from the information processing server 3 and stores the data in the storage part 20 in the information processing apparatus 2.
Here, Embodiment 2 is basically the same as the above-described Embodiment 1 in that the bicycle 1 with the information processing apparatus 2 acquires travel route information, and the operation of each part of the information processing apparatus 2. Hereinafter, the same parts as in the information processing apparatus 2 described in Embodiment 1 are assigned the same reference numerals, and overlapping descriptions will be omitted, but different points will be mainly explained.
With the information processing system according to the present embodiment, the information processing apparatus 2 is mounted on the bicycle 1, and a plurality of cyclists acquire data using a plurality of information processing apparatus 2 to create travel route information. Here, note that various data is communicated at any time between a plurality of information processing apparatuses 2 and the information processing server 3.
In addition, a configuration is possible where the information processing apparatus 2 only performs processing including measurement of various data and inputting cyclist's information; the information processing server 3 receives the data and creates travel route information; and each information processing apparatus 2 downloads and displays the travel route information. That is, the above-described functions of the travel route information creating part 30, the travel route information merging part 40 and so forth may be taken on by the information processing server 3 over the network 4.
For example, a system is possible that when information on a plurality of cyclists is uploaded via Internet, travel route information is automatically created in the server side and then downloaded in the information processing apparatus 2 and displayed. By using this information processing system, it is possible to provide services to send information including a map display area, a display size, running count information, exercise intensity, an exercise intensity value, from the information processing apparatus 2 to the information processing server 3 and search desired map information and download the information.
Here, the present embodiment adopts a configuration where only one information processing server 3, one computer 6 and two information processing apparatuses 2 are connected to each other via the network 4 in the information processing system. However, another configuration is possible where a plurality of information processing servers 3, a plurality of computers 6 and three or more information processing apparatuses 2 are connected to each other in the information processing system.
In addition to the above described embodiments, modification and alteration are encompassed in the present invention within the scope within which the object of the present invention can be achieved. For example, an amount of information of displayed routes may be changed according to the size of a displayed map area. To be more specific, when a bicycle map is displayed in a large area mode, a route used for running, for example, 100 or more times, is displayed as a standard. Meanwhile, when a bicycle map is displayed in a zoom mode to display a limited area, a route used for running one or more times is displayed as a standard. By this means, it is possible to keep a certain amount of travel route information and so forth displayed on the monitor 400 and prevent the display screen from becoming complex and being difficult to see for the cyclist, and therefore reduce cyclist's burden. In addition, the information processing apparatus 2 can reduce the period of time to read data from the storage part 20 and also reduce memory utilization.
Moreover, although with the above-described embodiments, a configuration has been described where the information processing apparatus performs computation and display while the bicycle is running, another configuration is possible, which provides a computation method or a program executed on a computer. For example, a program executed on a personal computer is provided, and the cyclist inputs a measurement result to the personal computer at home to save GPS information, and then computation as described above is performed, so that a bicycle map and so forth are displayed on a screen.
Moreover, start point information and end point information included in running information may be added to search results. For example, by inputting latitude and longitude information on the start point for search, map information is created using only the route group having the start point near the latitude and longitude, which is stored in the storage part 20. Then, the created map information is displayed on the monitor 40. By this means, when start point information is set as the cyclist's home, it is possible to know, for example, what routes the persons who live in the same neighborhood prefer and run. That is, it is possible to visualize search, comparison and so forth of travel routes in a user-friendly manner.
