Abstract
An electronic interaction apparatus for providing a 3D MMI is provided with a processing unit. The processing unit determines a first length between an object positioned at a first time and a surface formed by two digital camera modules, and a second length between the object positioned at a second time and the surface. Also, the processing unit determines a third length between the object positioned at a third time and the surface, and determines 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. Particularly, 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.
