Touch input has enriched our interaction with almost every application we use on mobile devices. With visualizations too, the promise it holds is compelling. The progress towards making visualizations touchable, however, has been surprisingly slow. In this talk, I highlight the key challenges with designing visualizations for touch-based devices, discuss the platforms available, present notable experiments in the space and shed light on the direction(s) we are headed.
