Abstract

A method and system are disclosed for implementing touch screen text entry on a screen in a first orientation. A web page is used for presenting a touch screen display, which allows text selection via a virtual keyboard. Selected alphanumeric characters are displayed on the screen in an orientation matching the first orientation of the screen.

Claims

1. A method, comprising:

providing a screen having a horizontal axis that is parallel to a least one edge of the screen and a vertical axis that is perpendicular to the horizontal axis and parallel to at least one other edge of the screen;

rendering a web page on the screen such that content associated with the web page is provided in a first orientation that is parallel to one of the horizontal axis and the vertical axis, the web page having a virtual keyboard;

receiving touch data from the virtual keyboard for at least one alphanumeric character; and

displaying the at least one alphanumeric character on the screen in a second orientation that is parallel to a reference axis, wherein the reference axis forms an acute angle with respect to the horizontal axis and an acute angle with respect to the vertical axis.

2. The method of claim 1, wherein the at least one alphanumeric character is displayed on the screen as a graphic image of the alphanumeric character.

3. The method of claim 1, further comprising:

representing the touch data by a first coordinate and a second coordinate;

transforming the touch data by transposing the first coordinate and the second coordinate; and

transmitting the transformed data to a server as serial data over a network.

4. The method of claim 3, wherein the network is an Ethernet.

5. The method of claim 3, further comprising:

running a web browser on a set-top box connected to the screen; and

polling the server for data using the web browser.

6. The method of claim 5, further comprising:

providing the transformed data to the set-top box; and

displaying a graphic image of the at least one alphanumeric character on the screen by refreshing only a portion of the web page occupied by the graphic image.

7. The method of claim 3, further comprising:

in response to polling by a set-top box connected to the screen, providing the transformed data from the server to the set-top box; and

displaying the at least one alphanumeric character on the screen using hypertext markup language document object model (HTML DOM).

8. A method, comprising:

providing a screen operable in at least one orientation;

rendering a web page on the screen, the web page having a virtual keyboard;

wherein the rendering of the web page further comprises;

loading on the web page graphic images of all alphanumeric characters shown on the virtual keyboard, the graphic images having orientations that match the screen orientation; and

displaying the virtual keyboard;

receiving touch data from the virtual keyboard for at least one alphanumeric character; and

displaying the at least one alphanumeric character in a text entry area of the screen in an orientation that is parallel to a reference axis,

wherein the orientation of the reference axis is independent of the at least one orientation.

9. The method of claim 8, wherein the at least one alphanumeric character is displayed on the screen as a graphic image of the alphanumeric character.

10. The method of claim 8, further comprising:

representing the touch data by a first coordinate and a second coordinate;

transforming the touch data by transposing the first coordinate and the second coordinate; and

transmitting the transformed data to a server as serial data over a network.

11. The method of claim 10, further comprising:

providing the transformed data to a set-top box connected to the screen; and

displaying a graphic image of the at least one alphanumeric character on the screen by refreshing only a portion of the web page occupied by the graphic image.

12. A system, comprising:

a screen having a horizontal axis that is parallel to a least one edge of the screen and a vertical axis that is perpendicular to the horizontal axis and parallel to at least one other edge of the screen, the screen configured for displaying a web page having a virtual keyboard for entering touch data corresponding to at least one alphanumeric character;

rendering a web page on the screen such that content associated with the web page is provided in a first orientation that is parallel to one of the horizontal axis and the vertical axis, the web page having a virtual keyboard;

and

a control module that displays the at least one alphanumeric character in a second orientation that is parallel to a reference axis, wherein the reference axis forms an acute angle with respect to the horizontal axis and an acute angle with respect to the vertical axis.

13. The system of claim 12, wherein the first orientation is a portrait orientation.

14. The system of claim 12, further comprising:

a serial network interface that processes the touch data; and

a server for receiving the processed touch data.

15. The system of claim 14, wherein the touch data is represented by a first coordinate and a second coordinate, and the serial network interface further processes the touch data by transposing the first coordinate and the second coordinate.

16. The system of claim 15, further comprising:

a set-top box connected to the screen, wherein the set-top box displays the at least one alphanumeric character on the screen based on data received from the server.

17. The system of claim 16, wherein the set-top box further displays a graphic image of the at least one alphanumeric character on the screen by refreshing only a portion of the web page corresponding to a display location of the at least one alphanumeric character.

18. The system of claim 13, wherein the means for displaying the at least one alphanumeric character includes:

a network interface that processes the touch data; and

a server that transforms the processed touch data into a data format to display the at least one alphanumeric character on the screen.

19. A system, comprising:

a screen operable in at least one orientation;

a control module that;

renders a web page on the screen, the web page having a virtual keyboard;

loads on the web page graphic images of all alphanumeric characters shown on the virtual keyboard, the graphic images having orientations that match the screen orientation; and

displays the virtual keyboard;

a touch tracker module that receives touch data from the virtual keyboard for at least one alphanumeric character; and

a control module that displays the at least one alphanumeric character in a text entry area of the screen in an orientation that is parallel to a reference axis, wherein the orientation of the reference axis is independent of the at least one orientation.

20. The system of claim 19, wherein the at least one alphanumeric character is displayed on the screen as a graphic image of the alphanumeric character.

21. The system of claim 19, further comprising:

an interface that represents the touch data by a first coordinate and a second coordinate;

a touch adapter module that transforms the touch data by transposing the first coordinate and the second coordinate; and

a serial network interface that transmits the transformed data to a server as serial data over a network.

22. The system of claim 21, wherein the control module further:

provides the transformed data to a set-top box connected to the screen; and

displays a graphic image of the at least one alphanumeric character on the screen by refreshing only a portion of the web page occupied by the graphic image.
