Digit Wireless has created a mobile device keypad approach that adds a full alphabet's worth of buttons to a standard numeric layout. The company claims FasTap, which it is showcasing at the Intel Developer Forum this week, is no larger than a typical mobile phone keypad.

The FasTap keypad layout has 26 round alphabetical buttons and 18 rectangular numeric and function buttons arranged in a grid-like array, with the alphabetic buttons situated at the corners of the numeric and function buttons.

Users need not be as careful as when using standard, 12-key keypads that require multiple taps to select a number or letter. Instead, with the FasTap approach, the user taps just once to indicate each desired letter or number.

Accidental letter-taps are ignored, via a software alrogithm that assumes users are much more likely to accidentally hit letters keys -- which are raised relative to the number keys -- than number keys. By ignoring letter taps that occur essentially simultaneously with number taps, virtually all input errors are eliminated, according to Digit Wireless founder and CTO David Levy.

According to Levy, Telus Mobility, a major wireless phone carrier in Canada, already has begun supplying a FasTap-enabled LG phone to its customers, with promising results.
