A GOMS theory of stimulus-response compatibility is shown to predict response-time performance on a command/abbreviation encoding task. Working with parameters that were set by an earlier study and which have rational, task-meaningful interpretations as mapping, motor, perception and retrieval operators, zero-parameter predictions were made that fit the observed performance with r

= 0.776 (p<0.05). The reasonableness of the parameters, the algorithms used to generate the predictions, and the weighting assumption used to combine algorithms into a single prediction are discussed.

Since humans direct their visual attention by means of eye movements, a device which monitors eye movements should be a natural βpickβ device for selecting objects visually present on a monitor. The results from an experimental investigation of an eye tracker as a computer input device are presented
