Abstract

A position-bias compensation method, applied to a three-dimensional image interactive system, includes steps of: displaying a three-dimensional image and setting a trigger position in a preset interactive coordinate system according to a default position of a user; obtaining a position-bias of a user'"'"'s position from the default position; and resetting the trigger position according to the position-bias.

Claims

1. A position-bias compensation method, applied to a three-dimensional image interactive system having a display-and-interactive device, comprising steps of:

displaying a three-dimensional image and setting a trigger position in a preset interactive coordinate system according to a default position of a user by the display-and-interactive device;

obtaining a position-bias of a user'"'"'s position from the default position; and

resetting the trigger position according to the position-bias of the user'"'"'s position by equations;

2. The position-bias compensation method according to claim 1, wherein resetting the trigger position comprises a step of:

resetting the trigger position through modulating the trigger position in the preset interactive coordinate system.

3. The position-bias compensation method according to claim 1, wherein resetting the trigger position comprises a step of:

resetting the trigger position through resetting the preset three-dimensional image coordinate.

4. The position-bias compensation method according to claim 1, wherein the three-dimensional image is composed by the first image and the second image which has an aberration to the first image, and is visible by the user wearing three-dimensional glasses.

5. The position-bias compensation method according to claim 1, further comprising a step of:

triggering the three-dimensional image interactive system to perform a response action in response to a user'"'"'s action moving an object to pass through the reset trigger position in the preset interactive coordinate system.

6. The position-bias compensation method according to claim 5, wherein the response action is implemented by sound feedback, tactile feedback, visual feedback, or a command input.

7. The position-bias compensation method according to claim 1, wherein resetting the trigger position comprises steps of:

determining a direction from the trigger position to the reset trigger position in the interactive coordinate system according to a direction of the position-bias; and

determining a distance from the trigger position to the reset trigger position in the interactive coordinate system according to the value of the position-bias.

8. The position-bias compensation method according to claim 3, further comprising a step of:

resetting the preset three-dimensional image coordinate according to the position-bias, wherein the reset three-dimensional image coordinate is configured for displaying the three-dimensional image.

9. The position-bias compensation method according to claim 8, wherein resetting the preset three-dimensional image coordinate comprises steps of:

determining a direction from the preset three-dimensional image coordinate to the reset three-dimensional image coordinate according to a direction of the position-bias; and

determining a distance from the preset three-dimensional image coordinate to the reset three-dimensional image coordinate according to the value of the position-bias.

10. A three-dimensional image interactive system, for interacting with a user, comprising:

a display-and-interactive device, configured for displaying a three-dimensional image and setting a trigger position in a preset interactive coordinate system according to a default position of the user;

a detecting device, configured for detecting a position-bias of the user'"'"'s position to the default position; and

a compensation unit, coupled by signal to the detecting device and the display-and-interactive device, and configured for receiving the position-bias and resetting the trigger position in the preset interactive coordinate system according to the position-bias of the user'"'"'s position by equations;

11. The three-dimensional image interactive system according to claim 10, wherein the three-dimensional image is composed by the first image and the second image which has an aberration to the first image, and is visible by the user wearing three-dimensional glasses.

12. The three-dimensional image interactive system according to claim 10, wherein the three-dimensional image interactive system performs a response action in response to a user'"'"'s action moving an object to pass through the reset trigger position in the preset interactive coordinate system.

13. A position-bias compensation device, applied to a three-dimensional image interactive system for displaying a three-dimensional image and setting a trigger position in a preset interactive coordinate system according to a default position, comprising:

a detecting device, configured for detecting a position-bias of the user'"'"'s position to the default position; and

a compensation unit, coupled by signal to the detecting device and a display-and-interactive device, and configured for receiving the position-bias and resetting the trigger position in the preset interactive coordinate system according to the position-bias of the user'"'"'s position by equations;

14. The position-bias compensation device according to claim 13, wherein the 3D image is composed by the first image and the second image which has an aberration to the first image, and is visible by the user wearing three-dimensional glasses.
