Today’s mobile phones and tablets have been designed and engineered to enable concurrent vibration along with audio, flashlight and visuals on the display. For users with hearing impairment, feedback from audio alone cannot work independently in the process of communicating. Vibrations can play a major role for such users in their interactions with mobile devices. This design research seminar report includes a compilation of primary and secondary research done with respect to users with hearing impairment and also presents a compilation of the current trends in interaction technology with respect to vibrations. The later part of this report presents experiments done on user groups, about their perceptions of different vibration patterns (inspired from musical concepts like rhythm cycles/time signatures/taals and tempos) and their abilities in mapping those vibration patterns to visual or textual memory cues.
