Personal Space Technologies™ PSS™ - Technical Specifications
The PSS technology
high resolution, unobstructed stereo images presented in real-time
The user looks at the monitor via a mirror. This enables the user to bring his hands into the same environment as the virtual 3D-objects without interrupting the visual image.
natural and direct intuitive 3D input
The user is 'attracted' to the objects he sees; his natural reaction is usually to grab and manipulate them.
Interaction devices are used to follow the hand movements and give the ability to interact with and manipulate the volumetric images intuitively and with great precision. The hand movements are optically tracked with sub millimeter accuracy and immediately translated to movements of the virtual objects.
