Hereinafter, the health management server 10, the mobile communication terminal 20, and the device for measuring a moving distance 100 will be described. First, the health management server 10 collects, generates, manages, analyzes, and provides health management information for managing the user's health. Here, the health management information includes at least one of the user's personal information, diet information, and exercise information.

The sensor module 150 detects a motion, for example, a motion of the device for measuring a moving distance 100. For instance, when the user puts the device for measuring a moving distance 100 on himself/herself or the device for measuring a moving distance 100 is mounted on an object, the device for measuring a moving distance 100 moves integrally with the user or the object at a mounted position. At this point, the sensor module 150 can sense a movement of user or object on which the device 100 is mounted, and measures the motion. Here, the sensor module 150 can be at least one of an acceleration sensor, a gravity sensor, a terrestrial magnetism sensor, a gyro sensor, and a motion sensor. For example, the sensor module 150 may include an acceleration sensor to detect acceleration of a mounted point. That is, the acceleration sensor detects at least one of acceleration in perpendicular and horizontal directions. The acceleration sensor may also be a three-axis acceleration sensor that detects acceleration in a perpendicular direction and acceleration of two components of a horizontal direction.
Referring to
Further, the controller 170 calculates the total moving distance and/or controls a configuration of the device for measuring a moving distance 100. A detailed description of the controller 170 will be described later in a method of measuring a moving distance.
Hereinafter, a method of measuring a moving distance according to the present invention will be described with reference to
The method of measuring a moving distance according to an embodiment of the present invention includes at least one of step of acquiring health management information (S101), step of mounting a device for measuring a moving distance to a user or an object (S102), step of selecting a moving mode (S103), step of detecting a motion (S104), step of acquiring each of a plurality of unit moving distances based on the motion (S105), step of acquiring health management information including a total moving distance by adding up the acquired plurality of unit moving distances (S106), and step of outputting the acquired health management information or transmitting the acquired health management information to an external device (S107). Here, the step of acquiring the unit moving distance includes at least one of step of determining a substantially stopped time point based on the motion (S105-1), step of determining a step start point and a step end point of the time points (S105-2), step of initializing a moving speed at the step start point (S105-3), step of acquiring a moving speed from the step start point to the step end point based on the detected motion and the moving speed at the step start point (S105-4), and step of acquiring a unit moving speed based on the moving speed from the step start point to the step end point (S105-5). Such a method of measuring a moving distance may include all the above-described steps or may selectively include only some steps. Hereinafter, each step that can be included in a method of measuring a moving distance according to the present invention will be described with reference to
Referring to
As shown in
Next, the device for measuring a moving distance 100 is mounted to an object to be measured (S102). The object to be measured may be, for example, a person, an animal, or anything that moves. As shown in
Referring to
Next, the device for measuring a moving distance 100 detects a motion by the sensor module 150 (S104). The sensor module 150 detects a motion by detecting acceleration according to a user's movement. As shown in
Moreover, the sensor module 150 detects acceleration of at least one direction. For example, the sensor module 150 may detect acceleration of a perpendicular direction and acceleration of a horizontal direction. Alternatively, the sensor module 150 may be a three-axis acceleration sensor. The three-axis acceleration sensor can detect acceleration of a perpendicular direction and acceleration of two components of a horizontal direction. Here, the acceleration of a perpendicular direction is acceleration of substantially 9.8 m/s in a gravity direction even when no acceleration exists. As such, a stop time point when a foot reaches the ground can be only the acceleration of a horizontal direction. Here, when acquiring the stop time point the horizontal direction when the foot reaches the ground, it can be clearly seen whether a user's feet is grounded regardless of movement of a horizontal direction of a riding means even when obtaining a moving distance of the user within the riding means moving in a horizontal direction.
Next, the device for measuring a moving distance 100 acquires each of a plurality of unit moving distances based on the motion. Here, the unit moving distance is a moving distance for calculating a total moving distance and is a unit moving distance from the stop time point to a next stop time point. Specifically, when the user walks, the user repeatedly passes a time point at which one foot is grounded, a time point at which one foot takes off the ground and moves, and a time point at which one foot is again grounded. Here, a time point at which one foot is grounded is a step start point, and a time point at which one foot is again grounded is a step end point. A unit moving distance is a moving distance from the step start point to the step end point. This unit moving distance corresponds to a stride.
Here, acquiring a unit moving distance includes all or some of step of determining a time point that substantially stops based on motion (S105-1), step of determining a step start point and a step end point of time points (S105-2), step of initializing a moving speed at the step start point (S105-3), step of acquiring a moving speed from the step start point to the step end point based on the detected motion and the moving speed of the step start point (S105-4), and step of acquiring a unit moving distance based on the moving speed from the step start point to the step end point (S105-5). Hereinafter, each steps included at step of acquiring the unit moving distance (S105) will be described.
The acquiring the unit moving distance includes, a step of first the controller 170 determining a substantially stopped time point based on the detected motion (S105-1). The substantially stopped time point is a time point when an absolute value of acceleration reaches a predetermined threshold value or less. Alternatively, the substantially stopped time point may be a time point at which an absolute value of acceleration is sustained to a predetermined threshold value or less for a predetermined time period.
For example, as shown in
Here, at least one of a threshold value and a predetermined time is determined according to the selected moving mode. For example, the threshold value may be in decreasing order from a walking mode, a race-walking mode, to a running mode. For another example, a predetermined time may be a smaller value in a decreasing order from the walking mode, the race-walking mode, to the running mode.
For example, as shown in
As described above, when the sensor module 150 detects acceleration of a perpendicular direction and/or a horizontal direction, a substantially stopped time point is determined based on at least one of acceleration of the perpendicular and the horizontal direction. When the user walks or runs, the movement is of a horizontal direction. Therefore, a more accurate result can be obtained by determining a stop time point using acceleration of a perpendicular direction. Further, when this determination is based on acceleration of a horizontal direction, the quantity of acceleration sensors can be reduced and thus a production cost can be reduced. In addition, when a user rides on an object moving in a horizontal direction, acceleration of a perpendicular direction is not influenced by acceleration of a horizontal direction of the moving object, which provides a more accurate result.
Next, the device for measuring a moving distance 100 determines a step start point and a step end point (S105-2). Here, the controller 170 determines which one should be the step start point and the step endpoint. Here, when a user moves while repeating steps, a step end point may become a step start point of a next step. For example, as shown in
Next, the device for measuring a moving distance 100 initializes a moving speed at a step start point (S105-3). The controller 170 initializes a moving speed at the determined step start point. For example, as shown in
Next, the device for measuring a moving distance 100 acquires a moving speed from a step start point to a step end point speed based on the detected acceleration and a moving speed of a step start point (S105-4). Here, the controller 170 including an integration circuit performs step of acquiring a moving speed from the step start point to the step end point. The controller 170 acquires a change amount of the moving speed from a step start point to a specific time point by integrating the detected acceleration with respect to a time from the step start point to the specific time point. Here, the controller 170 acquires a moving speed of a specific time point by adding up a moving speed of the step start point and a change amount of a moving speed until the specific time point. When the moving speed of the step start point is initialized, the moving speed may be a predetermined value the moving speed from the step start point to the step end point can be sequentially acquired based on the detected acceleration. This is represented by Equation 1. First, a change amount of a moving speed from the step start point to the specific time point is described as follows.
Δv(ti→t)=∫t
In Equation 1, a(t) is detected acceleration, t is a specific time point, ti is a time of a step start point, and Δv is a time change amount until a specific time point. That is, a sequential change amount of the speed is obtained by integrating sequential acceleration from a step start point to a specific time point. By adding an initial moving speed to a sequential change amount of a moving speed, a sequential moving speed can be acquired.
v(t)=vi+Δv(ti→t) [Equation 2]
In Equation 2, v(t) is a sequential moving speed, and vi is a speed at a step start point. Because vi is initialized to a predetermined value, i.e., ‘0’, a sequential moving speed is finally a sequential change amount of a moving speed from a step start point to a specific time point.
Referring to
Δs(ti→t)=∫t
In Equation 3, Δs is a moving distance from a step start point to a specific time point. As can be seen in Equation 3, such a moving distance can be obtained by integrating the moving speed with a time.
Δsif=Δs(ti=tf) [Equation 4]
In Equation 4, a moving distance from the step start point to the step end point is a unit moving distance. Here, when acquiring the moving distance from the step start point to the step end point, a moving speed is acquired by integrating the detected acceleration and a moving distance is acquired by integrating again the moving speed. Here, when the moving speed is not initialized, an error occurs in the moving speed according to the detected acceleration, and the speed error may be sequentially accumulated. When integrating a moving speed including the accumulated error, accumulative error of the moving distance exponentially increases. Therefore, as a total moving distance increases, an error value increases and thus an accurate moving distance cannot know. According to am embodiment of present invention, as shown in
Referring to
ΔD=ΣΔsif [Equation 5]
In Equation 5, ΔD is a total moving distance and is acquired by adding up unit moving distances. Alternatively, the controller 170 may acquire a moving speed based on acceleration detected by the sensor module 150, initialize a moving speed every step start point to a predetermined value, and acquire a total moving distance by integrating a moving speed over an entire moving time with respect to a time. When adding up unit moving distances or initializing a moving speed every step start point and acquiring a total moving distance using acceleration, an error at every start point is removed and resulting in minimizing an accumulative error. As such, the device for measuring a moving distance 100 can acquire an accurate total moving distance.
Further, the controller 170 calculates the total number of steps by counting the quantity of step start points and generates other health management information using the acquired total moving distance and health management information stored in the storage unit 160. For example, the controller 170 may acquire an exercise amount or consumption calorie based on a total moving distance, a user's weight, and a kind of moving modes. Further, the controller 170 may acquire an average unit moving distance based on a total moving distance and the total number of steps.
Next, the device for measuring a moving distance 100 outputs the acquired health management information and/or transmits the acquired health management information to an external device (S107). For example, the controller 170 controls the output unit 130 to output health management information, and/or controls the communication unit 140 to transmit the health management information to the mobile communication terminal 20 or the health management server 10. In this case, the information transmitted or outputted from the device for measuring a moving distance 100 may include at least one of a unit moving distance, an average unit moving distance, a moving mode, a total moving distance, an exercise amount, and consumption calorie.
Moreover, the mobile communication terminal 20 receives such information and displays the information to a user. For example, when the mobile communication terminal 20 may receive a signal that instructs to enter a moving distance measurement mode from the user and enter in a moving distance measurement mode the mobile communication terminal 20 provides the above information to the user. Alternatively, the device for measuring a moving distance 100 can be formed as a single device together with the mobile communication terminal 20.
As described above, the device for measuring a moving distance 100 performs communication with an external device. Hereinafter, a method of performing communication the device for measuring a moving distance 100 and the external device will be described.
An individual health equipment, such as the device for measuring a moving distance 100, performs communication with a manager device. In general, the individual health equipment has a low computing capability, whereas the manager device, such as a mobile communication terminal 20, a personal computer, and a set top box, has a storing place of stronger calculation performance and a larger capacity. The manager device communicates with the health management server 10 by sharing information with the individual health equipment supplementing its insufficient performance with the manager device. Further, when the individual health equipment performs only wired communication or local area communication, the individual health equipment shares information with the health management server 10 through the manager device.
Here, the individual health equipment and the manager device may include an application layer and a transport layer. The application layer may perform various functions related to a function of the health equipment. For example, the application layer of the device for measuring a moving distance 100 may measure a stride of the user and displays the stride on a screen. Further, the transport layer may receive and transmit information from the application layer. For example, the transport layer of the device for measuring a moving distance 100 may transmit information about a moving distance acquired by the application layer to the mobile communication terminal 20.
Moreover, the individual health equipment and the manager device may perform communication with a point to point method that includes steps of connecting the transport layers of the individual health equipment and the manager device, associating the application layers of the individual health equipment and the manager device, and transmitting and receiving, by the individual health equipment and the manager device, the health management information.
First, the transport layers of the individual health equipment and the manager device can be connected. Before the power is first supplied to the individual health equipment, the individual health equipment is in a disconnected state. In this disconnected state, information cannot be exchanged between the transport layers of the individual health equipment and the manager device. When the individual health equipment of the disconnected state receives a transport connect display message from the manager device, the transport layers of the individual health equipment and the manager device become connected according to the transport connect display message. Then, when the transport layers of the individual health equipment and the manager device are connected, by entering a connected state, information can be transmitted and received between the transport layers.
The application layers of the individual health equipment and the manager device may be associated. The connected state includes an unassociated state, an associating state, and an associated state. The associated state is a state that can transmit and receive information as the application layers of the individual health equipment and the manager device form a logical path for exchanging information. For example, the associated device for measuring a moving distance 100 may transmit and receive health management information to the mobile communication terminal 20. In the associating state, the individual health equipment and the manager device of an unassociated state perform an operation to be associated. Here, in the unassociated state, the transport layers of the individual health equipment and the manager device are first connected, but the application layer may be in an unassociated state. The individual health equipment and the manager device of the unassociated state cannot exchange information of the application layer.
As described above, in order for the individual health equipment of an unassociated state to be associated with the manager device, the individual health equipment may enter an associating state. The individual health equipment and the manager device of the associating state perform an associating procedure to be associated is executed. The associating procedure includes transmitting, by the individual health equipment, an association request message to the manager device, receiving, by the manager device, the association request message, generating, by the manager device, an association response message to the received association request message, receiving, by the individual health equipment, the association request message, and associating, by the individual health equipment, with the manager device according to the received association request message. Hereinafter, steps included in the associating procedure will be described.
Furthermore, the individual health equipment may transmit the association request message to the manager device. Here, the association request message includes a version of the association protocol and a data protocol list for at least one data protocol in which the individual health equipment supports. Further, the data protocol list includes at least one data protocol information and a data protocol ID for identifying a kind of the data protocol.
Here, the data protocol ID may identify a type of the data protocol that the individual health equipment supports. For example, the data protocol ID may be information identifying whether or not a data protocol that the individual health equipment supports is a data protocol of a predetermined specification or a data protocol according to a specification in which an individual health equipment manufacturer separately provides. Here, the predetermined specification may include, for example, ISO/IEEE 11073 standard.
Further, the data protocol information may include information about the the data protocol according to the data protocol ID. The data protocol information includes a version of a data exchange protocol in which the individual health equipment supports, at least one encoding rule for an application protocol data unit in which the individual health equipment supports, a version of the nomenclature in which the individual health equipment supports, all functional units and an optional feature in which the individual health equipment supports, a system ID for uniquely identifying the individual health equipment, and a device configuration ID for identifying a current configuration of the individual health equipment.
Then, the manager device may receive the association request message to generate an association response message. Here, the association response message includes a result field reflecting a result of the association procedure, a version of a data protocol selected by the manager device among data protocols supported by the individual health equipment included in the data protocol list, an encoding rule selected by the manager device among encoding rules in which the individual health equipment supports, a version of the nomenclature selected by the manager device, a system ID for uniquely identifying the manager device, and a manager device configuration response for identifying a current configuration of the manager device.
Here, the version of the data protocol and the version of the encoding rule and the nomenclature may have a value that selects a data protocol, an encoding rule, and a nomenclature in which the manager device commonly supports among a data protocol, an encoding rule, and a nomenclature in which the individual health equipment supports based on the association request message. For example, when the association protocol, the data protocol, the encoding rule, and the nomenclature included in the association request message include an association protocol, a data protocol, an encoding rule, and a nomenclature in which the manager device supports, the manager device may accept the association. In this case, the result field has a value reflecting that association is accepted. If an association protocol, a data protocol, an encoding protocol, and a nomenclature included in the association request message do not include at least one of an association protocol, a data protocol, an encoding protocol, and a nomenclature in which the manager device supports, the manager device rejects association. In this case, the result field has a value reflecting that association is rejected. The manager device transmits the generated association response message to the individual health equipment.
Further, the individual health equipment may receive an association response message from the manager device. In this case, the individual health equipment receives an association response message for a predetermined time period. When the individual health equipment does not receive an association response message for a predetermined time period, the individual health equipment transmits again an association request message to the manager device. In this case, when the individual health equipment does not receive again an association response message for a predetermined time period, the individual health equipment abandons association and returns from an associating state to an unassociated state. In this case, the individual health equipment transmits an association abort message to the manager device. When the manager device transmits an association abort message, the manager device is changed from the associating state to the unassociated state.
The individual health equipment may be associated with the manager device in consideration of the received association response message. For example, when a result field of the association response message has a value reflecting that association is rejected, the individual health equipment abandons association and returns to an unassociated state. Specifically, for example, when an association protocol, a data protocol, and a set of operating parameters do not agree, or when the individual health equipment is not an authenticated equipment, the individual health equipment and the manager device may not be associated.
For another example, when a result field of the association response message has a value reflecting that association is accepted, the individual health equipment is associated with the manager device according to the association protocol. Here, when the manager device knows a configuration of the individual health equipment, the application layers of the manager device and the individual health equipment are directly associated. Further, when the manager device does not know a configuration of the individual health equipment, the individual health equipment transmits information about a configuration of the individual health equipment to the manager device, and thus the application layers of the manager device and the individual health equipment are associated.
Thereby, the individual health equipment and the manager device can perform communication for health management information by entering an associated state. Further, the user can acquire health management information through an exercise and perform an exercise or adjust an exercise amount in consideration of the health management information. Further, by transmitting and sharing the information to the mobile communication terminal 20 or the health management server 10, more systematic and comprehensive health management can be performed. Accordingly, more healthy society can be obtained.
The embodiments of the present invention may include many variations and modifications of the basic inventive concepts herein described, which may appear to those skilled in the art, will still fall within the spirit and scope of the exemplary embodiments of the present invention as defined in the appended claims.
