The projector 170 functions to output images captured by the camera 150 or an image scanned by the radar 160 to the inner surface of the glass faceplate 130.
As the projector 170 outputs the images or the image, information about the foreground and terrain in front of the glass faceplate 130 may be displayed on the glass faceplate 130.
As above, the glass faceplate 130 may function as a head-up display (HUD) in which images captured by the camera 150 or an image scanned by the radar 160 is displayed by the projector 170. Thus, in the following description, the HUD may be understood as the glass faceplate 130 through which image information is output by the projector 170.
The LED light 180 is provided on each of the left and right sides of the mask part body 110.
The LED light 180 functions to secure visibility in a dark underwater environment by emitting light.
The wearable part 200 is worn on the user's waist or arm and functions to supply power to the mask part 100 or control devices of the mask part 100.
The wearable part 200 may include a wearable part body 210 worn on the user's waist or arm; a fastening part 220 that fastens the wearable part body 210; the battery 230 that is provided on the wearable part body 210 and supplies power to the mask part 100 through the cable 300; and the controller 240 that controls the camera 150, the radar 160, the LED light 180, and the projector 170.
The wearable part body 210 is provided in a belt shape. In this case, the belt-shaped wearable part body 210 may be configured as a belt and worn around the user's waist, or may be configured as a bracelet and worn on the user's arm.
The fastening part 220 is provided at each end of the wearable part body 210 and functions to connect opposite ends of the wearable part body 210 to each other. As the opposite ends of the wearable part body 210 are fastened by the fastening part 220, the wearable part body 210 may be worn on the user's waist or arm.
The battery 230 is provided in the fastening part 220. In this case, a plurality of batteries 230 may be provided along the perimeter of the fastening part 220.
The batteries 230 may supply power to the mask part 100 through the cable 300.
The power supplied through the batteries 230 is supplied to the camera 150, the radar 160, the LED light 180, and the projector 170, so that the camera 150, the radar 160, the LED light 180, and the projector 170 may operate.
The controller 240 is provided in the fastening part 220. The controller 240 may control the operation of the camera 150, the radar 160, the LED light 180, and the projector 170. The controller 240 may receive images captured by the camera 150, correct the received images, and transmit the corrected images to the projector 170. Accordingly, the images captured by the camera 150 may be output to the glass faceplate 130.
The controller 240 may receive an image scanned by the radar 160, correct the received image, and transmit the corrected image to the projector 170. Accordingly, the image scanned by the radar 160 may be output to the glass faceplate 130.
When vision is blurry due to deep water or floating objects in the water, etc., the controller 240 may control the lighting intensity of the LED light 180, correct the images captured by the camera 150, correct the image scanned by the radar 160, and then provide the corrected images and image to the glass faceplate 130 by means of the projector 170.
The corrected images may be seen to some extent because of the LED light 180, which allows the user to move even in a turbid environment.
In addition, through the image scanned by the radar 160, reefs and obstacles may be identified, and by outputting this scanned image on the glass faceplate 130, the user may be prevented from hitting a reef.
The surrounding environments are captured in real time by the camera 150, and the controller 240 may obtain information on the captured images by comparing the captured images with data information previously stored in the controller 240. The information obtained may be the names and characteristics of reefs or underwater life.
For example, when a shark is around the user, and the camera 150 captures the shark, the controller 240 sends the shark's name and characteristics to the projector 170 by utilizing data information previously stored in the controller 240, and the projector 170 may output this received information to the glass faceplate 130 to warn the user. That is, the controller 240 may determine whether the underwater life captured by the camera 150 is dangerous on the basis of the data information previously stored in the controller 240 and inform the user of this through the glass faceplate 130 and the projector 170, that is, the HUD.
The wearable device 10 for scuba diving of the present disclosure may further include a communication device (not shown) provided on the mask part 100 or the wearable part 200 for wireless communication with a ship 20 or other users 30.
When the communication device is provided on the mask part 100, it is the mask part communication device 190, which will be described later, and when the communication device is provided on the wearable part 200, it is the wearable part communication device 250, which will be described later.
The wearable part 200 may further include the controller 240 that outputs a warning signal to the glass faceplate 130 by means of the projector 170 when the distance from the ship 20 or other users 30 increases.
The mask part 100 may further include the mask part communication device 190, and the wearable part 200 may further include the wearable part communication device 250.
The mask part communication device 190 is connected to the camera 150, the radar 160, the projector 170, and the LED light 180, whereas the wearable part communication device 250 is connected to the controller 240.
The mask part communication device 190 and the wearable part communication device 250 may be wirelessly connected to each other using Bluetooth or the like.
The mask part communication device 190 and the wearable part communication device 250 are connected to the plurality of batteries 230 and receive power from the plurality of batteries 230.
An electrical signal from the controller 240 may be transmitted to the camera 150, the radar 160, the projector 170, and the LED light 180 through the mask part communication device 190 and the wearable part communication device 250. Due to this, the controller 240 may easily control the camera 150, the radar 160, the projector 170, and the LED light 180.
For example, the controller 240 may measure brightness underwater, etc. on the basis of images of the surrounding environment captured by the camera 150, and may secure the user's field of view by adjusting the brightness by adjusting the lighting intensity of the LED light 180.
In addition, the controller 240 may detect surrounding obstacles and dangerous creatures such as reefs and sharks through the camera 150 and the radar 160 and inform the user of this through the glass faceplate 130 and the projector 170, that is, the HUD, so that the user may safely scuba dive.
As shown in
When the user becomes distant from other users 30 or from the ship 20, the controller 240 may notify the user of this by outputting a warning signal by means of the glass faceplate 130 and the projector 170, that is, the HUD, through wireless communication of the mask part communication device 190 or the wearable part communication device 250.
The controller 240 may measure the distance between the ship 20 and the wearable device 10 for scuba diving by measuring the distance between the first communication device 21, the second communication device 22, and the wearable device 10 for scuba diving by a triangulation method using wireless communication. Thus, the distance between the user and the ship 20 may be measured even underwater, where GPS is not possible.
In addition, by measuring the distance between the ship 20 and other users 30 by the triangulation method in the same manner as above and reflecting this distance, the distance between another user 30 and the user wearing the wearable device 10 for scuba diving may also be measured. Thus, the distance between the user wearing the wearable device 10 for scuba diving and another user 30 may be measured even underwater, where GPS is not possible.
In addition, by utilizing an underwater map pre-stored in the controller 240, images captured by the camera 150, and an image scanned by the radar 160, the controller 240 may implement a virtual map of the user's surrounding environment in real time, and output this map to the user by means of the glass faceplate 130 and the projector 170, that is, the HUD. The controller 240 may calculate locations of the ship 20 and other users 30 using the above-described triangulation method, and display the locations of the ship 20 and other users 30 in real time on the virtual map, that is, the mini-map 132.
As above, as the controller 240 informs the user of the user's current location, etc., it is possible to prevent an accident from occurring due to the user moving away from the ship.
The wearable device 10 for scuba diving may further include an oxygen tank 400 and a sensor part (not shown).
The sensor part (not shown) may include an oxygen sensor (not shown) that checks the remaining amount of oxygen in the oxygen tank 400; a position sensor (not shown) that measures the user's diving depth; a temperature sensor (not shown) that measures the water temperature; and a timer (not shown) that measures the diving time. The sensor part is connected to the controller 240, and the control of the controller 240 is performed based on the information measured by the sensor part. The mask part 100 may further include a humidity sensor (not shown) that measures water flowing into the interior of the glass faceplate 130.
The wearable part 200 may further include a floating part 260 provided on the wearable part body 210 to control buoyancy, and the controller 240 that increases the buoyancy of the floating part 260 to elevate the user out of the water when water is measured to flow into the interior of the glass faceplate 130 by the humidity sensor.
A plurality of floating parts 260 may be provided.
When water is measured to flow into the interior of the glass faceplate 130 by the humidity sensor, the controller 240 operates a navigation system that outputs the optimal route to a ship connected by wireless communication to the glass faceplate 130 by means of the projector 170.
The wearable part 200 may further include the floating part 260 provided on the wearable part body 210.
The floating part 260 controls buoyancy, and increases buoyancy when an emergency occurs, such as hitting a hazardous object or having no oxygen remaining, and the user must urgently get to the surface, thereby enabling the user to rise to the surface of the water.
The buoyancy of the floating part 260 is variable under the control of the controller 240.
For example, when the remaining oxygen level checked by the oxygen sensor falls below a preset value or when a collision occurs on a reef, the controller 240 operates the floating part 260 to increase buoyancy, thereby allowing the user to rise out of the water. In this case, the controller 240 may control the user's ascent speed by controlling the buoyancy of the floating part 260 to prevent the user from getting decompression sickness. That is, the controller 240 may control the user's ascent speed by controlling the buoyancy of the floating part 260 in consideration of the rate of change in water depth at which the user rises to the surface by means of the position sensor.
The controller 240 may operate a navigation system that displays the user's movement path by means of the virtual map created based on images captured by the camera 150 and an image scanned by the radar 160, and the glass faceplate 130 and the projector 170, that is, the HUD.
The mask part 100 may further include the humidity sensor. To be specific, the humidity sensor may be installed inside the mask part body 110 so as to be located inside the glass faceplate 130 of the mask part 100.
When the glass faceplate 130 is broken and water flows into the interior of the glass faceplate 130, the humidity sensor may measure the water or moisture flowing into the interior of the glass faceplate 130 and send a signal to the controller 240. When water is measured to flow into the glass faceplate 130, the controller 240 operates the floating part 260 to increase buoyancy, thereby raising the user out of the water. In addition, the controller 240 may operate the navigation system by outputting the optimal route to the ship connected through wireless communication to the glass faceplate 130 and the projector 170, that is, the HUD.
The cable 300 connects the mask part 100 and the wearable part 200, and functions to supply power to the mask part 100 by connecting the plurality of batteries 230 and the mask part 100.
The cable 300 includes not only a power line through which power is supplied, but also a communication line that transmits electrical signals from the controller 240 to the camera 150, the projector 170, the radar 160, the LED light 180, and the humidity sensor. In this case, the mask part 100 and the wearable part 200 may transmit and receive electrical signals by wire using the cable 300 rather than transmitting and receiving electrical signals wirelessly.
Unlike above, in the wearable device 10 for scuba diving, the mask part 100 and the wearable part 200 may be connected such that power is supplied wirelessly.
In other words, the batteries 230 of the wearable part 200 may wirelessly supply power to the mask part 100.
The wearable part 200 may further include an ultrasonic transmitter 251 connected to the batteries 230 and transmitting power via ultrasonic waves.
The ultrasonic transmitter 251 may be provided on the wearable part body 210.
The mask part 100 may further include an ultrasonic receiver 191 that receives power transmitted via ultrasonic waves from the ultrasonic transmitter 251.
The ultrasonic receiver 191 may be provided on the mask part body 110.
As above, the ultrasonic receiver 191 may receive power converted into ultrasonic waves from the ultrasonic transmitter 251 and supply power to the mask part 100.
In this way, the wearable device 10 for scuba diving may wirelessly supply power from the wearable part 200 to the mask part 100 even underwater, as power is supplied in the form of ultrasonic waves.
The oxygen tank 400 may further include a cable fixing part (not shown).
The cable fixing part functions to fix the cable 300.
Therefore, it is possible to prevent the cable 300 from becoming tangled or disturbed when the user swims underwater. The mask part 100 may further include: the gravity sensor 111 provided on the mask part body 110; the acceleration sensor 112 provided on the mask part body 110; the gyro sensor 113 provided on the mask part body 110; and the geomagnetic field sensor 114 provided on the mask part body 110.
The gravity sensor 111 functions to detect the direction of gravity.
The controller 240 may calculate the up and down directions underwater based on the direction of gravity measured by the gravity sensor 111.
The projector 170 may output the up and down directions underwater calculated by the controller 240 to the glass faceplate 130 through the 3D direction chart 131 as shown in
The acceleration sensor 112 functions to measure acceleration by detecting changes in the speed indicated by the mask part 100.
The controller 240 may measure the user's underwater speed wearing the wearable device 10 for scuba diving on the basis of the acceleration indicated by the mask part 100 measured by the acceleration sensor 112.
The gyro sensor 113 functions to recognize the tilt of the mask part 100 by detecting the rotation state of the mask part 100 in three axes.
The geomagnetic field sensor 114 functions to measure the geomagnetic field.
The controller 240 may calculate the user's orientation underwater, that is, the east, west, south, and north directions, on the basis of the geomagnetic field measured by the geomagnetic field sensor 114.
The projector 170 may output the calculated underwater direction to the glass faceplate 130.
The controller 240 may recognize six-axis directions by inputting rotation to acceleration by means of the acceleration sensor 112 and the gyro sensor 113.
The controller 240 may measure the real-time location of the user wearing the wearable device 10 for scuba diving on the basis of the location of the user wearing the wearable device 10 for scuba diving calculated through the above-described triangulation, and of changes in the user's speed and six-axis directions.
The controller 240 may calculate the user's location underwater on the basis of data measured by the acceleration sensor 112 and the gyro sensor 113 and transmit the calculated user's location to the projector 170. As shown in
In addition, the controller 240 may calculate the user's orientation underwater on the basis of the geomagnetic field measured by the geomagnetic field sensor 114 and transmit the calculated user's orientation to the projector 170. As shown in
The wearable device 10 for scuba diving of the present disclosure described above has the advantage of reducing the weight and volume of the mask part 100 by providing the plurality of batteries 230 and the controller 240 in the wearable part 200 rather than the mask part 100. Accordingly, when swimming underwater, it is possible to prevent the user's swimming from being interrupted by the mask part 100 being heavy and bulky.
The wearable device 10 for scuba diving of the present disclosure may easily determine the real-time location and orientation of the user wearing the wearable device 10 for scuba diving, and up and down directions underwater by means of the gravity sensor 111, the acceleration sensor 112, the gyro sensor 113, the geomagnetic field sensor 114, and the HUD provided in the mask part 100. Accordingly, it is possible to prevent accidents from occurring due to users losing direction in water where it is easy to lose direction.
Furthermore, since the sensors are attached to the mask part 100 worn on the user's head, the measured values of the sensors may be easily matched to values in the same direction as the user's field of view. Thus, user's orientation, location, etc. may be calculated using the measured values of the sensors without any additional correction.
Although preferred embodiments of the present disclosure have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions, and substitutions are possible, without departing from the scope and spirit of the present disclosure.
