Cost-effective hand gesture computer control interface

The article shows the design and implementation of a gesture control system, which determines the gesture from the movement of the hands. The presented gesture controller system can be built relatively easy from cheap components, so it is ideal development goal in case of a students' project also in the field of project based learning. The movement detected with distance measurement sensors, and the presented control interface determines the assigned gesture according to the hand's movement. The distance sensors are built into a box, along with a microcontroller. This controller did the signal pre-processing, which is an Arduino based unit. The signal post processing, filtering, and classification of gestures and the control of the computer are managed by a desktop application. The article presents the usability test of the gesture controlling system based on study carried out by test subjects.
