A one-dimensional visual tracking chip has been implemented us(cid:173) ing neuromorphic, analog VLSI techniques to model selective visual attention in the control of saccadic and smooth pursuit eye move(cid:173) ments. The chip incorporates focal-plane processing to compute image saliency and a winner-take-all circuit to select a feature for tracking. The target position and direction of motion are reported as the target moves across the array. We demonstrate its function(cid:173) ality in a closed-loop system which performs saccadic and smooth pursuit tracking movements using a one-dimensional mechanical eye.
