Proposal of interaction using breath on tablet device

Abstract

We would like to propose an interaction which is operated by blowing a breath on a screen of information terminal. Therefore, we propose and evaluate a device for detecting breath and an algorithm for identifying the breath. While it has been studied conventionally about expiration input device operated by a breath, users are not supposed to blow a breath on a touch panel like an ordinary manual operation on the touch panel but required to blow a breath toward a dedicated input sensor. In our proposed system, it has become possible for a user to perform operations such as selection and determination of objects displayed on a screen by detecting a breath blown out toward a screen of information terminal. In this study, a breath interaction is proposed by allocating various breaths to various operations of a tablet terminal.
