Abstract:
1. A three-dimensional virtual input and simulation apparatus, comprising a plurality of point light sources, each point light source being capable of simultaneously and continuously emitting a point like point scattering light source; a plurality of 2D optical positioning devices with a visual axis tracking function, each 2D optical positioning devices receiving a synchronization enable signal and all scattering light sources simultaneously emitted by the point light sources, whereby measuring the 3D positions of all point light sources and outputting a set of physical quantities, each 2D optical positioning devices being equipped with a visual axis tracking function for automatically tracking the central group coordinate of all point light sources and the coordinate of one of the point light sources and outputting its own visual axis angle, so as to achieve the visual axis tracking purpose, and each 2D optical positioning devices further being equipped with a visual axis positioning function to receive a visual axis angle for setting the angular direction of its own visual axis, so as to achieve the visual axis positioning purpose; and a control analysis unit, having a control analysis procedure, being a software procedure mainly used to connect and control all 2D optical positioning devices, outputting a synchronization enable signal for synchronously starting all 2D optical positioning devices to do the 3D position measurement, and also outputting a set of angular direction of visual axis for setting the angular direction of visual axis of each 2D optical positioning devices, so as to achieve the visual axis positioning purpose for all 2D optical positioning devices, and further receiving all physical quantities and a group of a visual axis angles to simulate an input function of a physical input device, so as to achieve the virtual input purpose, and also to simulate the motion of a physical object, so as to achieve the purpose of simulator; wherein the single 2D optical positioning devices with a visual axis tracking function comprises:
