This thesis project consists of developing a hand-held, one-thumb input device small enough to be placed on gestural controllers and providing performers with a simple way to select between multiple options with few movements of a thumb.
Most commercial input devices for the thumb make the assumption that buttons are the de facto standard. However, buttons are not always the best solution especially where space is very limited. This project explores a new approach to input design by analyzing the thumb’s movements and designing a suitable input device that can track them. The design progression from the first to the last prototype is presented in great detail.
The final prototype is compared to other existing one-thumb input devices used in gestural controllers and mobile computing. The shortcomings of each one-thumb input method is described with the final prototype presented as a possible solution in each case.
