摘要:
Provided are a virtual optical input device and a method of controlling the same. In the method, a portion of an input means such as a finger, and a portion of a shadow of the input means generated by a light source are detected through image processing. Physical variations formed between them are used to detect the touch contact of the input means, calculate the position of the input means, and input the corresponding command. Accordingly, it is possible to provide various input patterns.
