Abstract

The present invention discloses a virtual touch control apparatus and a method thereof. The virtual touch control apparatus includes a virtual touch interface for generating a graphic display; a remote controller device controllable by a user to interact with the virtual touch control interface, wherein the interaction between the remote controller device and the virtual touch control interface generates a coordinate or an action command; a data format converter device converting the coordinate or action command into data with a format compatible to a physical touch control apparatus; and a processor for processing the converted data.

Claims

1. A virtual touch control apparatus, comprising:

a virtual touch interface for generating a graphic display;

a remote control device controllable by a user to interact with the virtual touch interface, wherein the interaction between the remote control device and the virtual touch interface generates a coordinate or an action command;

a data format converter converting the coordinate or action command to data with a format compatible with a format of a physical touch control apparatus; and

a processor for processing the converted data.

2. The virtual touch control apparatus as claimed in claim 1, wherein the interaction between the remote control device and the virtual touch interface generates a relative coordinate, and the data format converter converts the relative coordinate to an absolute coordinate.

3. The virtual touch control apparatus as claimed in claim 1, wherein the data format converter converts the coordinate according to a ratio between an area of overall coordinate outputs of the remote control device and a size of the graphic display generated by the virtual touch interface.

4. The virtual touch control apparatus as claimed in claim 1, wherein the remote control device includes a button, and pressing and releasing the button indicate touching and being away from the virtual touch interface.

5. The virtual touch control apparatus as claimed in claim 4, wherein the time period when the button is pressed indicates virtual pressure on the virtual touch interface;

the longer the time period is, the higher the virtual pressure is.

6. The virtual touch control apparatus as claimed in claim 1, wherein when the remote control device is moved by an acceleration larger than a predetermined threshold, it indicates touching the virtual touch interface, and when the acceleration is not larger than the predetermined threshold, it indicates that the user is moving the remote control device but does not intend to touch the virtual touch interface.

7. The virtual touch control apparatus as claimed in claim 6, wherein when the acceleration is larger than the predetermined threshold, the larger the acceleration is, the higher the virtual pressure on the virtual touch interface is.

8. The virtual touch control apparatus as claimed in claim 1, wherein when the remote control device points to a location and stays for a time period longer than a predetermined threshold, it indicates touching the virtual touch interface;

when the remote control device stays pointing at the location for a time period not longer than the predetermined threshold, it indicates not touching the virtual touch interface.

9. The virtual touch control apparatus as claimed in claim 8, wherein when the time period that the remote control device stays pointing at the location is longer than the predetermined threshold, the time period is converted to virtual pressure on the virtual touch interface.

10. The virtual touch control apparatus as claimed in claim 1, wherein the remote control device and the virtual touch interface interact with each other by optical communication, and wherein if one of the remote control device and the virtual touch interface detects an optical signal from the other, it indicates touching the virtual touch interface, and any coordinate change afterward indicates pure movement without touching the virtual touch interface.

11. The virtual touch control apparatus as claimed in claim 1, wherein the remote control device and the virtual touch interface interact with each other by optical communication, and wherein if one of the remote control device and the virtual touch interface detects an optical signal from the other, it indicates touching the virtual touch interface, and any coordinate change afterward indicates movement while keeping touching the virtual touch interface.

a remote controller of a television or a video player, a controller or pointing device of an electronic entertainment apparatus, an object capable of projecting light, and an object capable of receiving light.

13. A virtue touch control method, comprising:

providing a virtual touch interface for generating a graphic display;

providing a remote control device;

generates a coordinate or an action command by interaction between the remote control device and the virtual touch interface;

converting the coordinate or action command to data with a format compatible with a format of a physical touch control apparatus; and

processing the converted data.

14. The virtue touch control method as claimed in claim 13, wherein the interaction between the remote control device and the virtual touch interface generates a relative coordinate, and the method further comprises:
