This project aims to explore those interactions and forms that arise when trying to incorporate fingerspelling gestures into consumer mice. I looked at existing mouse designs, identified parameters that constitute the mouse user experience, and developed concepts that incorporate fingerspelling into those mice. For my P1, I designed a novel interaction technique called Fingerspelling. It is a single-handed numeric text entry method that involves lifting fingers resting on a mouse or a trackpad to input numeric data without disrupting the normal functioning of a mouse. While I had a working prototype, I had completely neglected the ergonomics and user experience of the device.
