Gaurav Manek likes to work with Arduino and experiment with
different means of remote control. His latest project involves several new technologies relating to gesture- and web-based control.
This project extends a simple remote-controlled car, allowing it to be controlled by an iPad or by hand gestures. This project builds on the Arduino project, the Kinect and certain HTML5 features (WebSockets, DeviceMotionEvent, Canvas).
Check out his webpage for a detailed explanation of this project, including source code and schematic.
