title: Using Fitts's law for evaluating Tongue Drive System as a pointing device for computer access.
abstract: In this paper, the results of a 2-D center-out task in a Fitts's law experiment have been presented for measuring the performance of the Tongue Drive System (TDS). Although the end-user population for TDS is individuals with tetraplegia, in this study, we recruited 6 able-bodied subjects in 3 sessions, conducted in 3 consecutive days. They performed the same task with their right hand using a standard mouse for achieving a baseline as well as a standard keypad with their right index finger. The resulting average throughput for TDS, keypad, and mouse were 1.67, 2.17, and 3.99 bit/s, respectively.
