Abstract: A virtual control device is provided for an electronic device. The virtual control device includes a first lens, a second lens, a first photosensitive unit, a second photosensitive unit and a processor unit. The first photosensitive unit is arranged behind the first lens by a focal length, and obtains a first image via the first lens. The second photosensitive unit is arranged behind the second lens by the focal length, and obtains a second image via the second lens. The processor unit determines the object-position coordinates of a virtual control plane according to a first position of the projection of the object on the first photosensitive unit and a second position of the projection of the object on the second photosensitive unit, and the processor unit provides the object-position coordinates to the electronic device.
