60.3L: Late‐News Paper : Algorithm for Recognizing Pinch Gestures on Surface‐Capacitive Touch Screens
Jiro Yanase, Kenichi Takatori, Hideki Asada · SID Symposium Digest of Technical Papers · 2015
Pinch gestures for scaling an image were recognized successfully on a surface‐capacitive touch screen that has only a single‐touch function without increasing manufacturing cost. An algorithm for recognizing the gestures was developed, which calculates the distance between two touching points without detecting each position of the two points.
