Abstract

A sensing device for generating orientation data when positioned or moved relative to a surface, the orientation data being indicative of an orientation of the sensing device relative to the surface, the surface having coded data disposed upon it, the coded data being indicative, when sensed by the sensing device, of the orientation, the sensing device including: a housing; orientation sensing means configured to generate the orientation data using at least some of the coded data; and communications means configured to communicate the orientation data to a computer system.

Claims

1. A sensing device for enabling joystick control of software or hardware, in at least one rotational direction, the sensing device being configured to interact with a command surface, the command surface including user information and coded data, the coded data being indicative of a plurality of reference points of the command surface, the sensing device including:

a sensor for sensing at least some of the coded data as the sensing device is used to interact with at least some of the user information on the command surface;

processing means for processing at least some of the sensed coded data to generate indicating data, the indicating data being indicative of;

at least one dimension of rotational orientation of the sensing device relative to the command surface; and

a position of the sensing device relative to the surface;

a transmitter for transmitting the indicating data, the indicating data being useable to enable the control of the software or hardware.

2. The sensing device of claim 1, wherein the rotational orientation includes at least a roll of the sensing device relative to the control surface.

3. The sensing device of claim 2, configured to determine the dimension of rotational orientation by determining a rotational position of at least some of the sensed coded data in a frame of image data captured by the sensor.

4. The sensing device of claim 1, wherein the rotational orientation includes at least one of yaw and pitch of the sensing device relative to the surface.

5. The sensing device of claim 4, configured to determine the dimension of the at least one of yaw and pitch by determining a perspective distortion of at least some of the sensed coded in a frame of image data captured by the sensor.

6. The sensing device of claim 5, wherein the coded data includes periodic elements, and the sensing device is configured to determine the at least one of yaw and pitch by determining the perspective distortion based on the relative positions of at least some of the periodic elements in the frame of image data.

7. The sensing device according to claim 1, wherein the coded data is substantially invisible.

8. The sensing device according to claim 7, wherein the user information includes an icon that indicates, to a human, that interacting with the icon with the sensing device will cause the sensing device to be used as a controller.

9. The sensing device of claim 1, further including a memory for storing an identity of the sensing device, the indicating data including the identity, thereby enabling identification of the sensing device from which the indicating data was transmitted.
