Ha and Fu: Interface to Breathe on a Smartphone
Homei Miyashita, Hidenori Aoki · 2022
This study used front-camera face tracking to realize interactions such as blowing on a smartphone to make it foggy or tapping on it to make it puff. We used the parameters of the lower jaw opening, the lip closing, and the lip stretching to identify these actions. Additionally, we enabled pointing based on the position and direction of the face and implemented four applications using this interface.
