This invention provides a virtual input device. The virtual input device comprises an image device, a tip generation module, a display with an input interface and an inputted message area, a transformation device and a key-press determination device, wherein the input interface includes a first button corresponding to a first value, etc. The image device captures a plurality of environmental images based on the movement of a real object such as fingertip. The tip generation module, corresponding to the plurality of environmental images, generates a tip position parameter. The transformation device generates a virtual object on the input interface based on the tip position parameter. The key-press determination device selectively generates the first value on the inputted message area based on a set of virtual parameter of the virtual object.
