Abstract

In many small communication devices both a liq- uid crystal display (LCD) and a keypad are used by the consumer to direct software menu options such as set- ting the time of day, an alarm, various audible tones or scrolling through a message on the LCD screen. It is not very clear how to do any of these functions without carefully reading a detailed instruction manual, which generally leads to customer frustration and discontent with the product. Currently, to help the customer adapt to the software menu, blinking icons are used to indi- cate which menu is active, however, this doesn't clearly show the necessary keypad buttons that can be used to open or change this menu.

  In many small communication devices both a liq- uid crystal display (LCD) and a keypad are used by the consumer to direct software menu options such as set- ting the time of day, an alarm, various audible tones or scrolling through a message on the LCD screen. It is not very clear how to do any of these functions without carefully reading a detailed instruction manual, which generally leads to customer frustration and discontent with the product. Currently, to help the customer adapt to the software menu, blinking icons are used to indi- cate which menu is active, however, this doesn't clearly show the necessary keypad buttons that can be used to open or change this menu.

  To give more clarity to this procedure, the software menu can be directed via an independently backlit keypad. This will indicate exactly which keypad buttons

are active for a given menu screen, since they will be illuminated (see Figure 1). As a consequence, there won't be as many wasted keystrokes due to consumer use of trial and error methods to operate these software menus.

  A light emitting diode (LED) or similar device can be the source of illumination for the keypad, which will con- tain a translucent material for light transmission. Internally, the function controller of the communication device would recognize the currently active sothare menu sc...
