  • Virtual optical input device with feedback and method of controlling the same
    Patent number: 8698753
    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.
    Type: Grant

  • Virtual optical input device for providing various types of interfaces and method of controlling the same
    Patent number: 8508505
    Abstract: 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.

  • VIRTUAL OPTICAL INPUT UNIT AND CONTROL METHOD THEREOF
    Publication number: 20090295730
    Abstract: Provided are an input unit and a control method thereof. In an embodiment of the method, a portion of an input member such as a finger, and a portion of a shadow of the input member generated by a light source are perceived through image processing. Relationship information between the image and shadow of the input member are used, so as to determine if an input is made. Also, the input pattern can be provided to a user using an imaging light, whereas the images can be detected using a detection light.
