     The interaction in 3D space is gaining on importance. The classical means of interaction with mouse and keyboard are often unsatisfactory
for spatial applications, virtual reality is used more often than ever and so there is an increasing need for a cheap and accurate 3D positioning device.

      Such 3D locator was designed and constructed - it is a data acquiring device for tracking movement of the operator's hand. Alternative usage is as "3D mouse", which could be utilized in graphics systems as a replacement of a traditional "2D" mouse. The aim of this design is to gain a new faster way of entering points, curves and animations.

Keywords : Virtual reality, motion capture, 3D mouse
