Robots {robot, computer} can recognize patterns [Aleksander, 1983] [Liang et al., 1997]. QRio android robot can move and converse.
Kismet is a robot head whose parts can move like human head parts [Breazeal, 2001]. If it is too close to see, it cranes back, and if it is too far, it cranes forward. It checks for movement, skin color, and saturated colors and looks in weighted direction. State depends on happiness, stimulation, and willingness for new stimuli. State affects where it looks. It checks pitch for approving, disapproving, attending, and soothing patterns, as used worldwide by mothers to babies, but it has no language ability. It can make sounds in pitch patterns. It can move eyebrows, lips, and ears to reflect happiness, stimulation, and willingness for new stimuli.
In neuromorphic systems {silicon retina}, photodetectors output voltages proportional to current logarithm. Resistive network locally weights averages, so point effects decrease exponentially with distance. Retinal output is difference between local and overall voltage [Mead and Mahowald, 1991].
