With the modern computing systems becoming more and more complex,
simple ways of interaction with the end user are being researched.
Various approaches are being explored including hand and palm
gestures, retinal tracking and even brain waves measurements. While
the later require special equipment to implement, the former can be
accomplished using a simple camera, making it a preferred cost /
performance solution.
Human – Computer gesture based interaction has the potential to
speed-up work process, provide better user experience and simplify
otherwise complicated tasks. Since each user is different by nature
the input produced, while implying the same gesture can actually be
very different from user to user.
