Abstract

A touch-based interaction method includes the steps of: detecting a first ending touch point signal generated when a user at a first location touches a first ending touch point on a touch screen; upon detection of a disappearance of the first ending touch point signal, displaying a shortcut icon on a first area on the touch screen, wherein the first area is an area on the touch screen touched by the user locating at the first location; upon the user touching the shortcut icon, hiding the shortcut icon from the touch screen and displaying a menu interface on the touch screen, wherein the menu interface is located in the first area; detecting a close menu touch point signal generated when the user touches the touch screen outside of the menu interface; and upon detection of the close menu touch point signal, hiding the menu interface from the touch screen.

Claims

1. A touch-based interaction method, comprising:

detecting a first ending touch point signal generated when a user at a first location touches a first ending touch point on a touch screen;

upon detection of a disappearance of the first ending touch point signal, displaying a shortcut icon on a first area on the touch screen, wherein the first area is an area on the touch screen touched by the user locating at the first location;

upon the user touching the shortcut icon, hiding the shortcut icon from the touch screen, and then displaying a menu interface on the touch screen, wherein the menu interface is located in the first area;

detecting a close menu touch point signal generated when the user touches the touch screen outside of the menu interface; and

upon detection of the close menu touch point signal, hiding the menu interface from the touch screen.

2. The touch-based interaction method according to claim 1, further comprising:

upon hiding of the menu interface from the touch screen, displaying the shortcut icon on the first area on the touch screen.

3. The touch-based interaction method according to claim 1, further comprising:

projecting an image on the touch screen from at least one image source.

4. The touch-based interaction method according to claim 1, further comprising:

upon the disappearance of the first ending touch point signal, displaying the shortcut icon on a position of the touch screen wherein the position is adjacent to a long side of the touch screen and the position is located under the first ending touch point along a direction perpendicular to the long side of the touch screen.

5. The touch-based interaction method according to claim 1, wherein when a plurality of connecting touch points are generated by the user touching the touch screen continuously wherein the connecting touch points are contacted with each other, defining the last one of the connecting touch points as the first ending touch point.

6. The touch-based interaction method according to claim 1, further comprising:

detecting a second ending touch point signal generated when the user locating at a second location touches a second ending touch point on the touch screen; and

upon detection of a disappearance of the second ending touch point signal, the shortcut icon moving from the first area to a second area on the touch screen, wherein the second area is an area on the touch screen touched by the user locating at the second location.

7. The touch-based interaction method according to claim 6, wherein upon the disappearance of the second ending touch point signal, the shortcut icon moves on the touch screen from a first position to a second position, the first position is adjacent to a long side of the touch screen and the first position is located under the first ending touch point along a direction perpendicular to the long side of the touch screen, and the second position is adjacent to the long side of the touch screen and the second position is located under the second ending touch point along the direction perpendicular to the long side of the touch screen.

8. The touch-based interaction method according to claim 1, further comprising:

detecting a second ending touch point signal generated when the user locating at a second location touches a second ending touch point on the touch screen; and

upon the disappearance of the second ending touch point signal, the call interface moving on the touch screen from a first position to a second position, wherein the first position is adjacent to a long side of the touch screen and the first position is located under the first ending touch point along a direction perpendicular to the long side of the touch screen, and the second position is adjacent to the long side of the touch screen and the second position is located under the second ending touch point along the direction perpendicular to the long side of the touch screen.

9. The touch-based interaction method according to claim 1, wherein the menu interface comprises a tool menu, a drawing function menu, an image clearing menu, and an image switching menu.

10. The touch-based interaction method according to claim 9, wherein the tool menu comprises a plurality of function icons corresponding to a plurality of functions, an image displayed by the shortcut icon on the touch screen corresponds to one of the function icons chosen by the user.

11. The touch-based interaction method according to claim 10, wherein the function icons of the tool menu comprise a pen icon, an eraser icon, and a cursor icon.

12. The touch-based interaction method according to claim 1, wherein the touch screen is touched by a finger of the user or an object operated by the user.
