Interactive flat panel display and application switching method

Abstract

An application switching method is provided for an interactive display device. The application switching method includes receiving a touch event from a user; obtaining coordinates of the touch event; determining an application window corresponding to the coordinates; enabling the first application and transmitting the touch event to the first application when the application window is a first application; and enabling a second application and transmitting the touch event to the second application when the application window is not the first application.

Claims

1. An application switching method for an interactive flat panel display (IFPD), comprising the following steps: receiving a touch event from a user; obtaining coordinates of the touch event; determining an application window corresponding to the coordinates; enabling the first application and transmitting the touch event to the first application when the application window is a first application; and enabling a second application and transmitting the touch event to the second application when the application window is not the first application.

2. The application switching method as described in claim 1, wherein the interactive display device supports multi-window applications.

3. The application switching method as described in claim 1, wherein the first application is an application that includes handwriting input functionality and provides an independent input screen.

4. The application switching method as described in claim 1, wherein the second application is a annotation application that overlays handwriting input functionality onto the display screen of another application.

5. The application switching method as described in claim 1, wherein the coordinates are the starting position coordinates of the touch event.

6. The application switching method as described in claim 1, wherein the application window corresponding to the coordinate is the topmost application window among all windows containing the coordinate.

7. The application switching method as described in claim 1, further comprising: when the application window is the first application and the application window is not in the foreground, adjusting the first application window to the foreground.

8. An interactive flat panel display (IFPD) comprising: a touch screen for receiving a touch event from a user; a processing unit coupled to the touch screen and the touch screen for executing code; and a storage unit coupled to the processing unit for storing the code to instruct the processing unit to execute the following instructions: obtaining coordinates of the touch event; determining an application window corresponding to the coordinates; enabling the first application and transmitting the touch event to the first application when the application window is a first application; and enabling a second application and transmitting the touch event to the second application when the application window is not the first application.

9. The interactive display device as described in claim 8, wherein the interactive display device supports multi-window applications.

10. The interactive display device as described in claim 8, wherein the first application is an application that includes handwriting input functionality and provides a separate input screen.

11. The interactive display device as described in claim 8, wherein the second application is an annotation application that overlays handwriting input functionality onto the display screen of another application.

12. The interactive display device as described in claim 8, wherein the coordinates are the starting position coordinates of one of the touch events.

13. The interactive display device as claimed in claim 8, wherein the application window corresponding to the coordinate is the topmost application window among all windows containing the coordinate.

14. The interactive display device as described in claim 8, wherein the processing unit further performs the following: when the application window is the first application and the application window is not in the foreground, adjusting the first application window to the foreground.
