Personal communications devices such as pagers and personal communicators are getting smaller to meet the market need for portability and wearability. However, the range of features keeps increasing, and many of the more advanced devices in these categories are presently equipped with keypads for control and data entry. As the public's demand for delivery of personal ioforma- tion services increases, there will become a need for full ASCII character input to the device. This could be pro- vided by a "QWERTY" keypad, but its size will have to shrink smaller than a Bravo Pager. This presents a human engineering problem. Keypads need to be large enough to be digitally (tinger) activated. Stylus operation requires that the stylus be available, but a stylus is easily lost. The invention outlined here is one way to overcome the human engineering factors and yet use the minimum space for a finger pad and a display.
