A potential exploration of finger-specific interaction

We propose Finger-Specific Interaction (FSI) as a potential interaction technique for interactive surfaces. FSI treats each finger as completely independent, as one input primitive. This paper discusses the advantages and drawbacks of adopting FSI for use on interactive surfaces. The advantages include an increase of input primitives, enabling eyes-free interaction and the ability to differentiate between users. The drawbacks include the need for users to memorize the variety of operations for input assignments. We devised solutions to solve these drawbacks, and then developed some applications using them. We also developed other applications that utilize the compatibility with mobile devices.
