Recent evidence on the performance benefits of expanding targets during manual pointing raises a provocative question: Can a similar effect be expected for eye gaze interaction? We present two experiments to examine the benefits of target expansion during an eye-controlled selection task. The second experiment also tested the efficiency of a "grab-and-hold algorithm" to counteract inherent eye jitter. Results confirm the benefits of target expansion both in pointing speed and accuracy… CONTINUE READING
