Have you wondered what would it take to build an Android-based 80-inch touch surface? In the process of making my data viz tool VizInteract to work with large displays, I managed to find great answers to the question. Due to the need for vanilla android to send a video stream and read sequential touch events, a traditional Tablet with HDMI display out cannot serve the purpose. To solve this problem, we used the Android-x86 Open source project and an IR touch overlay to run android on the large display and support 12 touch points.

In this talk, I will share how I modified the Android-x86 kernel to add driver support for an IR touch overlay. I will share my learnings from building multi-touch experiences on unnaturally large surfaces and how that poses interesting challenges, especially for a data visualization tool. Most notably, what are the key changes in the UX of affording dragging, rotation, pinch to zoom and scale gestures on an 80-inch tablet vs a regular android tablet.
