Question

I want to make a program preferably in C# or Java that can access a video camera and recognize gestures. I have done programming before but this is the first time i require access to a pluggable hardware and control it. I dont want the whole program but just that how should i start.
How to make a programming language access a hardware.
Do i need external api for the hardware manufacturer
How can a camera be made to recognise gestured etc.

Answer 1

If writing in C# then you may want to look at Microsoft Kinect and the libraries and drivers they have for it. This would be much easier and more robust than writing a solution yourself using a camera.
