Abstract
A portable information display device has a backlit touch-sensitive display screen and a housing. The housing has a bezel portion which defines a perimeter of the display screen. The bezel has location identification means which identify touch-responsive icon regions on the display screen. The location identification means allow the device to be used in poor lighting conditions or by the sight-impaired. The user can trace the bezel until finding the location identification means which corresponds to the desired icon region. The desired icon region can then be touched to manipulate the displayed information.
