Paper Abstract:
|
We implemented a virtual keyboard interface using depth camera and projector. The primary function of this interface is to recognize the typed keys on the virtual keyboard. To make this function possible, we implemented several functions: (1) Generation of virtual keyboard from the projector, (2) Capture of depth image, (3) Detection of hands and extraction of fingertips, (4) Recognition of clicking gesture, and (5) Localization of typed key positions. This interface is useful to generate keyboard commands in any places when the user is walking around. |
