Study conducted to compare the functional performance of three types of input technologies with three devices: (1) HeadMaster Plus, from Prentke Romich, (2) Tracker 2000, from Madentec, and (3) Tracer, from Boost Technologies. Each device was used to produce a series of drawings of similar complexity until the participants achieved a stable level of performance. The number of trials required to achieve mastery, the speed of drawing at mastery, and the accuracy of drawings was compared for the devices. In addition, the participants were asked about their subjective experiences using the devices. Each of the three devices was fastest for different participants, but the HeadMaster Plus produced the most consistently fast drawing times. Results showed that while performance of the devices was somewhat similar, participant preferences were influenced more by comfort than by performance. The two fastest devices, the HeadMaster and the Tracer, both yielded complaints regarding comfort. The Tracker 2000 was preferred as the most comfortable device, yet was slightly slower in performance.
