Abstract
Provided are a virtual optical input device capable of providing feedback 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 and motion of the input means, and provide the corresponding feedback.
