Studying applications for touch-enabled mobile phone keypads
Paul Holleis, Jussi Huhtala, Jonna Häkkilä · 2008
We present a platform to evaluate mobile phone applications that make use of an additional dimension for key presses. Using capacitive sensors on each key, merely touching buttons as well as the force of the press can be measured. A set of applications well known from current mobile phones has been extended with functionality exploiting those new possibilities. The results of a study undertaken with this prototype are presented and conclusions are drawn for the design and implementation of such applications.
