The way children play iPad games could reveal if they have autism, researchers have found. They found those with the condition used greater force and moved their finger in different ways. It is hoped the app could lead to earlier diagnosis and treatment. The children were asked to play games on smart tablet computers with touch-sensitive screens and embedded movement sensors. Researchers at the University of Strathclyde and colleagues at the start-up Harimata added code to two commercially available games for children in order for them to capture sensor and touch-screen data as they children played.

Piano Tiles 2 is a touch-based mobile game that's lots of fun, and also maddeningly difficult. A normal person probably plays for a few weeks, gets frustrated, and uninstalls it. Thankfully, YouTuber DenverFinn is not normal. For him, the obvious solution was to build a robot that slips over an iPad and acts like human hands, only better. An iPhone overhead films the game at 120 frames-per-second and sends visual input to a controller that knows to seek out the black keys and avoid the white spaces.
