Build a switch similar to the one Stephen Hawking used

The Assistive Context Aware Toolkit (ACAT) supports a variety of sensors including ACAT Vision (camera based sensor) and most commercially available “off-the-shelf” sensors. However, for some users, using the camera based sensor may not be feasible due to their condition and the commercially available sensors may be too expensive. To bridge this gap, Intel Labs has developed an Arduino based proximity sensor solution that is also open source. If the potential ACAT user has financial constraints that prevent them from purchasing "off-the-shelf" sensors and has someone with minimal technical experience to help set up the Arduino proximity sensor, then this system may be the best solution for them. Additionally, the system is open source so developers can build on top of the system by adding new sensors, features, algorithms, etc. The

VCNL4010 proximity sensor used in the system best operates by detecting movements close to the sensor (within ~4cm). Some examples of ideal movements that could be detected by the sensor include: hand / finger movements, facial movements, and leg / foot movements. Set up of the sensor requires some soldering (about a couple minutes), finding someone that already knows how to do so is recommended. The sensor has holes for screws so it is flexible in terms of mounting options. You can find all the details here.
