CheekTouch: An affective interaction technique while speaking on the mobile phone

Abstract

We present a new affective interaction technique, called CheekTouch, by combining tactile feedback, delivered through the cheek, and multi-finger input, while speaking on the mobile phone. We designed a prototype by using a multi-touch mobile device and a 4x3 vibrotactile display device. We identified six affective touch behaviors (pinching, stroking, patting, slapping, kissing and tickling) that can be exchanged through one another's cheeks while speaking on the phone. We mapped the affective touch behaviors on tactile feedback expressions of the vibrotactile display. Results of a preliminary user study suggest that our technique is positively evaluated by the participants and applicable to intimate and emotional communication.
