Abstract

Joystick display data is generated for display on a touch screen of an electronic device. The joystick display data creates a visual representation of a virtual joystick when displayed on the touch screen. Touch data from the touch screen is processed to determine when the touch data indicates user interaction with the virtual joystick. When the touch data indicates user interaction with the virtual joystick, the joystick display data is adjusted to reflect the user interaction with the virtual joystick, based on the touch data, and joystick data is generated based on the user interaction with the virtual joystick. The display of at least one other element on the touch screen can be adjusted based on the joystick data.

generating orientation data that indicates an orientation of the virtual joystick;

comparing the orientation indicated by the orientation data to a nonlinear capture function that includes a range of orientations about a plurality of advantageous orientations that are advantageous to operation of the game;

generating the joystick data to indicate a selected one of the plurality of advantageous orientations when the orientation data compares favorably to the range of orientations corresponding to the selected one of the plurality of advantageous orientations;

generating the joystick data to indicate the orientation indicated by the orientation data when the orientation data compares favorably to another range of orientations, distinct from the range of orientations corresponding to the plurality of advantageous orientations; and

generating the joystick data to indicate a null orientation when the orientation data compares favorably to at least one null range of orientations, distinct from the range of orientations corresponding to the plurality of advantageous orientations and the another range of orientations, wherein the range of orientations about the plurality of advantageous orientations together with the another range of orientations and the at least one null range of orientations correspond to a full 360 degree range of possible orientations of the joystick data.

2. The method of claim 1 wherein display of the game object on the touch screen is controlled to indicate a first mode of motion when the orientation data compares favorably to the range of orientations corresponding to the selected one of the plurality of advantageous orientations;

and

wherein display of the game object on the touch screen is controlled to indicate a second mode of motion when the orientation data compares favorably to the another range of orientations.

3. The method of claim 1 further comprising:

determining the touch data indicates user interaction with the virtual joystick when the touch data corresponds to dragging the touch from inside the boundary to outside the boundary, wherein the boundary maintains a fixed position on the display screen;

wherein the joystick display data includes an indication of the boundary at the fixed position and the joystick display data maintains an actuator position within the boundary regardless of when the touch data corresponds to dragging the touch from inside the boundary to outside the boundary.

4. The method of claim 1 further comprising:

displaying visual orientation feedback on the touch screen, based on the joystick data, wherein the visual orientation feedback includes an orientation object that visually indicates an orientation selected by the virtual joystick, and wherein the object is separate from the visual representation of the virtual joystick and is separate from the game object, but displayed in conjunction with an axis centered on the game object.

5. The method of claim 4 wherein the game object is displayed at the selected one of the plurality of advantageous orientations and the visual orientation feedback is displayed at the orientation indicated by the orientation data.

6. The method of claim 1 further comprising:

generating instruction data for display on the touch screen, wherein the instruction data generates a display of a visual prompt on the touch screen that instructs the user on use of the virtual joystick.

7. The method of claim 6 further comprising:

terminating the display of the visual prompt when the touch data indicates user interaction with the virtual joystick.

8. The method of claim 1 wherein generating joystick display data for display on the touch screen includes modifying a position of the virtual joystick on the touch screen in response to a user selection of the position of the virtual joystick.

9. The method of claim 1 further comprising:

processing the touch data to determine a bias corresponding to the user interaction with the virtual joystick;

wherein generating the joystick data based on the user interaction with the virtual joystick includes bias compensation.

10. The method of claim 1 wherein the virtual joystick includes at least one adjunct button that is selectable in response to user interaction;

wherein processing the touch data further includes determining when the at least one adjunct button is selected; and

wherein generating the joystick data includes generating button selection data when the at least one adjunct button is selected.

11. A method for use in conjunction with an electronic device that includes a touch screen, the method comprising:
