Graphical representations
A controller for a display device includes a processor configured to receive an indication of the orientation of a user of the display device; receive an indication of the orientation of the display device; and generate a graphical representation of a user of the display device using the received indications, such that the orientation of the graphical representation of the user is adapted based on the orientation of the display device.
1. A controller for a display device, the controller comprising:
a processor configured to
receive a first angle of orientation of a user of the display
device with respect to a magnetic north and a second angle of orientation of the display device with respect to the magnetic north; and
generate a graphical representation of the user such that the orientation of the graphical representation of the user is based on a difference between the second and first angles,
wherein when the difference is 0 the graphical representation is a back of the user.
2. The controller as claimed in claim 1 , wherein the received orientation of the user is rotated around a vertical axis of the graphical representation by the second angle.
3. The controller as claimed in claim 1 , wherein the graphical representation of the user is a mirror image of the user when displayed on the display device.
4. The controller as claimed in claim 3 , wherein the graphical representation is mirrored prior to display by the display device.
5. The controller as claimed in claim 1 , wherein the orientations of the user and the display device are given with respect to a predetermined direction.
6. The controller as claimed in claim 5 , wherein the predetermined direction is magnetic north.
7. The controller as claimed in claim 1 , wherein the orientations of the user and the display device are given in three dimensions.
8. The controller as claimed in claim 1 , wherein the processor is further configured to receive a movement and/or posture of the user, and to generate the graphical. representation that corresponds to the movement and/or posture of the user.
9. The controller as claimed in claim 1 , wherein the processor is further configured to animate the graphical representation to demonstrate movements and/or postures to the user when the graphical representation is displayed on a display device.
10. The controller as claimed in claim 9 , wherein the movements comprise a plurality of basic movements that together form a complex movement, each basic movement comprising the movement of a single joint.
11. The controller as claimed in claim 10 , wherein the graphical representation comprises first and second graphical representations, the first graphical representation being animated to demonstrate the plurality of basic movements, and the second graphical representation being animated to demonstrate the complex movement.
12. The controller as claimed in claim 9 , wherein the graphical representation is animated to indicate a current ability of the user relative to a desired ability.
13. The controller as claimed in claim 1 , wherein the display device includes a sensor for determining the orientation of the display device.
14. The controller as claimed in claim 13 , wherein the sensor is a magnetometer.
15. The controller as claimed in claim 14 , wherein the sensor further comprises an accelerometer.
16. A method of generating a graphical representation of a user for display on a display device, the method comprising acts of:
receiving a first angle of orientation of the user of the display
device with respect to a magnetic north and a second angle of orientation of the display device with respect to the magnetic north; and
generating a graphical representation of the user such that the orientation of the graphical representation of the user is based on a difference between the second and first angles,
wherein when the difference is 0 the graphical representation is a back of the user.
17. A non-transitory computer readable medium comprising computer program code that, when executed on a processor, performs a method of generating a graphical representation of a user for display on a display device, the method comprising:
receiving a first angle of orientation of the user of the display device with respect to a magnetic north and a second angle of orientation of the display device with respect to the magnetic north; and
generating a graphical representation of the user, such that the orientation of the graphical representation of the user is based on a difference between the second and first angles,
wherein when the difference is 0 the graphical representation is a back of the user.
