Abstract:
1. An electronic interaction apparatus for providing a 3D man-machine interface (MMI), comprising: a processing device, determining a first length between an object positioned at a first time and a surface formed by two digital camera devices, determining a second length between the object positioned at a second time and the surface, determining a third length between the object positioned at a third time and the surface, and determining a depth in a virtual 3D space corresponding to the object positioned at the third time according to the first length, the second length, and the third length, wherein the virtual 3D space is displayed in a display screen, the third time is later than the first time and the second time, and the third length is longer than the first length and shorter than the second length, wherein the processing device determines the depth in the virtual 3D space using the following formula: where L
