Applying low latency touch sensor technology to mobile devices

Today, mobile devices fail to achieve their full potential of direct input, despite of advancements on touch sensing technology. One of the factors is the inclusion of input latency that results in objects lagging behind the user's finger, instead of kept under the finger, breaking the belief of direct manipulation of virtual objects. Tactual Labs core product is a touch sensor that has very little input latency, supporting sensor response time down to 10ms, well below the current standard of 75-120ms. My objective is to leverage Tactual Lab’s low latency sensor to understand to what extent latency affects the human performance and to utilize this understanding to improve upon the current design of mobile devices. Once an understanding of latency’s effects on user performance has been achieved, a touch-based experience can be untelligently designed to take into account low latency and react accordingly to human’s limitations, thus providing a final experience where latency is controlled and, imperceptible by users. To study latency I propose the following methodology: (1) understand the effect of latency in human performance....
