FingerSense-Augmenting Expressiveness of Physical Button by Fingertip Identification

In this paper, we propose a novel method, FingerSense to enhance the expressiveness of physical buttons. In a FingerSense enabled input device, a pressing action is differentiated according to the finger involved. We modeled the human performance of FingerSense interfaces and derived related parameters from a preliminary usability study. Overall findings indicate that FingerSense is faster compared with traditional keypads when the finger switching action could be paralleled.
