In repetitive workflows like CAD, short, redundant and seemingly trivial sets of movements can add up to cause siginificant fatigue and/or time wastage. The project Single-Handedly develops and tests a novel one-handed interaction technique that enables the user to ‘fingerspell’ numbers to a computer mouse to input numbers into a computer. We designed a way to intuitively encode numbers into finger gestures executable while holding a mouse, built two electronic prototypes and user tested the interaction technique as a full-fledged input method to find its capability. In CAD applications, while switching between mouse and keyboard might be quicker for numeric entry, it requires taking one’s eyes off the screen to locate the keys. Our tests show that fingerspelling prototypes are better for such workflows than keyboard and mouse.

GuidingBand
GuidingBand
Prof. Anirudha Joshi
Computerised guidance systems can help alleviate tedious everyday tasks such as identifying a desired object in a collection of similar objects. Such guidance systems can prove useful as microinteractions if they are made accessible as a consumer wearable that delivers tactile feedback. We designed a wrist-wearable tactile guidance system called GuidingBand that provides vibrational cues to help the user pick visual targets out of an array. We conducted two studies to evaluate it. The studies involve presenting visual targets to users on a screen and giving them visual search tasks. It was surprising that instead of improving the precision of the users' performance, their visual perception in fact deteriorated it.
This work is accepted at and will be presented as a research paper at INTERACT 2023 in York, United Kingdom.
