Investigation of Respiratory Input Interface Using Respiration Estimation Method Based on Electrocardiogram

Abstract

Current input interfaces for games are designed mainly for able-bodied people, and the needs of physically challenged people are not fully considered. In this study, we attempted to develop a new input interface using respiration which is a natural action for everyone. However, conventional methods of measuring respiration are less comfortable and not suitable for prolonged use. Therefore, we created a command input to the game based on respiration estimated from the electrocardiogram (ECG). The results suggest that the respiration estimated from the ECG might be used as an input to the game.
