Touch-Screen and Method for an Electronic Device
First Claim
1. An electronic device, comprising:
- a display for presenting information to a user; and
an infrared detector, comprising;
at least four infrared transceivers disposed about the display such that light from the at least four infrared transceivers is projected across a surface of the display; and
a controller, operable with each of the at least four infrared transceivers, wherein the controller is configured to detect which of the at least four infrared transceivers receives a most reflected light signal, and to correlate an infrared transceiver receiving the most reflected light signal with one of a plurality of user modes of operation.

Abstract
A touch sensitive display for an electronic device includes a display (201) for presenting information to a user and at least four infrared transceivers (202,203,204,205) disposed about the display (201). The four or more infrared transceivers (202,203,204,205) can be disposed about the display (201) such that infrared light (206,207,208,209) from each of the infrared transceivers (202,203,204,205) projects across a surface (303) of the display (201). A controller (214), which is operable with the infrared transceivers (202,203,204,205), is configured to detect which of the infrared transceivers (202,203,204,205) has the most reflected signal (702). The controller (214) can then correlate this and other information with one of a plurality of user modes of operation. A control menu (802) can then be presented on the display (301) in accordance with the user mode of operation to mitigate finger blockage.

16. A computer-readable medium in a portable electronic device comprising a display and at least four infrared transceivers disposed about the display, the computer-readable medium including instructions for performing a method, when executed by a processor coupled with the computer-readable medium, for determining a user mode of operation, the method comprising:
-
determining, from signals received from the at least four infrared transceivers, which infrared transceivers receives a most reflected infrared signal; correlating which infrared transceiver receives the most reflected infrared signal with one of a plurality of user modes of operation; and presenting a menu of user selectable options on the display in a location based upon the one of the plurality of user modes of operation. - View Dependent Claims (17, 18, 19)

20. A method, configured as embedded code operative with a processor in a portable communication device, for presenting an unobscured menu to a user on a display, the method comprising:
-
receiving, from four or more infrared transceivers disposed about the display, signals indicating reflection of infrared light from a user digit on the display; determining which signal is indicative of most reflection; correlating an infrared transceiver receiving the signal indicative of most reflection with the user digit extending from one side of the display into the display; and presenting the unobscured menu distally from the one side of the display.
