Ten operators had to complete a complex visuo-motor task in two extreme presentation conditions, 2D dislocated display and 3D collocated display. Using 3D collocated display operators had better total time performance as well as improved error time performance. In all conditions learning occurred. Error-time improvement following training in the 3D collocated condition carried over to a following 2D dislocated condition but there was no carry over following a block of 2D dislocated display.

Previous studies have argued for the use of gaze-assisted pointing techniques (MAGIC) in improving human-computer interaction. Here, we present experimental findings that were drawn from human performance of two tasks on a wall-sized display. Our results show that a crude adoption of MAGIC across a range of complex tasks does not increase pointing performance. More importantly, a detailed analysis of user behavior revealed several issues that were previously ignored (such as, interference of corrective saccades, increased decision time due to variability of precision, errors due to eye-hand asynchrony, and interference with search behavior) which should influence the development of gaze-assisted technology.
