Passive Haptic Learning (PHL) can be used to teach text entry systems such as Braille and Morse code where each finger controls at most one key. However, most keyboards have a spatial layout where each finger controls multiple keys, and each key is labeled. Can PHL help users improve their skill at these text entry systems? We are investigating these questions by using passive stimuli to help users learn a randomized layout of the number pad. This research is aimed at laying the groundwork for creating a system to help individuals improve their QWERTY keyboard typing.
