Each smart hair is composed of Shape Memory Alloy(s) (SMA) imbedded within a thin cylinder of silicone and a small drive circuit.
Its unique, creature-like motion attracts people who see the interface.
The motion of each hair is controlled by light patterns from LCD/LED, etc. In other words, visual images could be used to control their motion.
Such method contributes improving flexibility in configuration. Then, various devices that have light source, such as ipads and iphones, could be equipped with their own "hair".
This should contribute improving communication between human and artificial devices.
