Interactive facial robot system on a smart device Enhanced touch screen input recognition and robot´s reactive facial expression

This paper suggests an interactive facial robot system on a smart device which has a touch screen and a built-in microphone. The recognition process for touch inputs is enhanced by analyzing input patterns and a built-in microphone. Recognized results from the input procedure are converted to emotional states of the system, and then the emotional states are reactively expressed at a facial simulator displayed on the device´s touch screen. Therefore, the proposed facial system can be implemented in one smart device at which input sensors and a visual output are on a same display component.
