Exercise mat, entertainment device and method of interaction between them
View Patent ↗An exercise system includes a flexible exercise mat having a flexible body and a plurality of lights incorporated into the flexible body and visible in use on a surface of the flexible body. The system also includes an entertainment device having an input to receive a captured video image of a scene with the flexible exercise mat having the lights visible thereon. An image processor of the entertainment device detects positions of the lights within the image, and a processing device calculates a configuration of shape adopted by the exercise mat based upon the detected positions of the lights. In one mode, the lights are arranged to indicate a configuration of shape adopted by the exercise mat due to a surface upon which it has been placed. The entertainment device modifies a behaviour of an application in response to the configuration of shape of the exercise mat.
1. An exercise system, comprising:
a flexible exercise mat, comprising:
a flexible body; and
a plurality of lights incorporated into the flexible body and visible in use on a surface of the flexible body; and
an entertainment device, comprising:
an input configured to receive a captured video image of a scene comprising the flexible exercise mat having the plurality of lights visible on its surface;
an image processing device configured to detect the positions of the plurality of lights within the video image; and
a processing device configured to calculate a configuration of shape adopted by the exercise mat based upon the detected positions of the plurality of lights;
wherein:
in a first mode, the plurality of lights are arranged to indicate a configuration of shape adopted by the exercise mat due to a surface upon which it has been placed, and
the entertainment device is configured to modify a behaviour of an application run by the entertainment device in response to a configuration of shape of the exercise mat calculated by the processing device.
2. An exercise system according to claim 1 , in which the mat further comprises:
a lighting control input configured to receive, from a remote entertainment device, signals controlling one or more selected from the list consisting of:
i. activation or deactivation of the plurality of lights;
ii. the activation or deactivation of a subset of the plurality of lights;
iii. a brightness level of some or all of the plurality of lights; and
iv. a colour of some or all of the plurality of lights.
3. An exercise system according to claim 1 in which, in a second mode, an activation, a brightness, and/or a colour of a subset of the plurality of lights is responsive to the configuration of shape adopted by the exercise mat due to the surface upon which it has been placed.
4. An exercise system according to claim 1 , in which the flexible exercise mat further comprises:
one or more pressure sensors incorporated into the flexible body of the flexible exercise mat; and
a pressure level output configured to transmit, to a remote entertainment device, signals indicative of pressure values from at least one of the one or more pressure sensors.
5. An exercise system according to claim 1 in which, in a second mode, an activation, a brightness, and/or a colour of a subset of the plurality of lights is responsive to a proximity of the subset to a pressure sensor incorporated into the flexible body of the exercise mat.
6. An exercise system according to claim 1 , in which the flexible exercise mat further comprises:
one or more vibration units incorporated into the flexible body of the flexible exercise mat, and
a vibration control input configured to receive, from a remote entertainment device, signals controlling at least one of the one or more vibration units.
7. An exercise system according to claim 1 , in which the flexible exercise mat further comprises:
one or more flexure sensing units incorporated into the flexible body of the flexible exercise mat; and
a flexure level output configured to transmit, to a remote entertainment device, signals indicative of flexure values from at least one of the one or more flexure sensors.
8. An exercise system according to claim 2 in which, in the first mode, the flexible exercise mat is configured to change the activation, brightness level, and/or colour of a subset of the plurality of lights responsive to a lighting control signal defining an asymmetric pattern on the flexible exercise mat.
9. An exercise system according to claim 1 , in which the entertainment device further comprises a lighting control output to transmit, to the flexible exercise mat, signals controlling one or more selected from the list consisting of:
i. activation or deactivation of the plurality of lights;
ii. the activation or deactivation of a subset of the plurality of lights;
iii. a brightness level of some or all of the plurality of lights; and
iv. a colour of some or all of the plurality of lights.
10. An exercise system according to claim 9 , in which the entertainment device is configured to modify the activation, brightness level, and/or colour of the subset of the plurality of lights to produce an asymmetric pattern on the flexible exercise mat.
11. An exercise system according to claim 1 , in which the entertainment device is configured to estimate a pose of a user of the flexible exercise mat responsive to which of the plurality of lights is visible within the captured video image.
12. An exercise system according to claim 1 , in which the entertainment device is configured to detect an input from a user responsive to a flexure value from a flexure sensor at a predetermined position in the flexible exercise mat.
