Ng, Albert, Lepinski, Julian, Wigdor, Daniel, Sanders, Steven and Dietz, Paul (2012): Designing for low-latency direct-touch input. In: Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 453-464.

Software designed for direct-touch interfaces often utilize a metaphor of direct physical manipulation of pseudo "real-world" objects. However, current touch systems typically take 50-200ms to update the display in response to a physical touch action. Utilizing a high performance touch demonstrator, subjects were able to experience touch latencies ranging from current levels down to about 1ms. Our tests show that users greatly prefer lower latencies, and noticeable improvement continued well below 10ms. This level of performance is difficult to achieve in commercial computing systems using current technologies. As an alternative, we propose a hybrid system that provides low-fidelity visu-al feedback immediately, followed by high-fidelity visuals at standard levels of latency.
