Tracking fingers with the Wii Remote

Using an IR led array and some reflective tape, you can track fingers in thin air using the Wii Remote by Johnny Chung Lee, Carnegie Mellon University. The grid software is a custom program written using a C# wiimote library and DirectX. More information about the grid software can be found at http://www.cs.cmu.edu/~johnny/projects/wii/

00:00:35.110 --> 00:00:35.120 align:start position:0%
an infrared camera this camera is just

00:00:35.120 --> 00:00:37.190 align:start position:0%
an infrared camera this camera is just

00:00:37.190 --> 00:00:37.200 align:start position:0%
like any other video camera we use but

00:00:37.200 --> 00:00:39.470 align:start position:0%
like any other video camera we use but
it's<00:00:37.360><c> sensitive</c><00:00:37.800><c> only</c><00:00:38.079><c> to</c><00:00:38.280><c> infrared</c><00:00:38.760><c> light</c>

00:00:39.470 --> 00:00:39.480 align:start position:0%
it's sensitive only to infrared light

00:00:39.480 --> 00:00:41.869 align:start position:0%
it's sensitive only to infrared light
that's<00:00:39.680><c> why</c><00:00:39.920><c> it</c><00:00:40.039><c> can</c><00:00:40.200><c> track</c><00:00:40.719><c> points</c><00:00:41.200><c> like</c><00:00:41.600><c> the</c>

00:00:41.869 --> 00:00:41.879 align:start position:0%
that's why it can track points like the

00:00:41.879 --> 00:00:44.670 align:start position:0%
that's why it can track points like the
Nintendo<00:00:42.280><c> sensor</c><00:00:42.640><c> bar</c><00:00:43.280><c> or</c><00:00:43.760><c> light</c><00:00:43.960><c> bulbs</c><00:00:44.399><c> or</c>
