While most of the cellphone manufacturers are still busy perfecting the touchscreen interface for mobile phones, two Japanese scientists have developed a new input method for cellphones. The developers, Professor Masatoshi Ishikawa and Dr. Takashi Komuro of the Tokyo University, are calling it the "vision-based input interface".
The system uses the front camera of cellphone which recognises all the five fingers of the user. The System binarizes the images of the fingertip and uses it as a template image. Then it tracks thefingertip in input images about translation, rotation and scale. In that way, the positions and postures of the fingertips are estimated. The user can wave his fingers in front of the camera for different inputs. The system allows user to text, browse, click and perform some other functions without physically touching the cellphone.
Below is a video showing the functioning of a system. The camera used in this demo is a 154 FPS (frame per second) sensor, which is much better than the front (so called secondary) cameras of the currently available handsets. For this system to be put to a commercial use, the secondary cameras of the cellphones would need to be bettered. For now, enjoy the video and do tell us if you would like to see this new system in the cellphones of future. For further details you can also check out The Paper here.
