Tokyo University professors, Masatoshi Ishikawa and Takashi Komuro, have developed a new control interface for mobile phones which could ultimately rival the touchscreen display.
The so-called “vision-based input interface” uses a tiny camera to record movements of the user’s fingers then translate these movements into commands. Although this technology will undoubtedly involve a learning curve for users, it could potentially allow for faster and more dynamic control than a built-in keyboard or touchscreen display.
