Patent application number | Description | Published |
20090322685 | Computer input device using touch switch - Input device of computer using touch switch. Electronic signal flows between touching conducting pads. The microcontroller in main portion detects the said electronic signal and recognizes which pads are touched to generate the input signal. The pad portion may further contain acceleration sensor and in this case the microcontroller recognizes the touching impact strength of pad by analyzing the output of acceleration sensor to generate input signal. The input signal of touching pad and the touching impact strength generated by microcontroller can be transmitted to outer system like PC by communication portion in main portion. | 12-31-2009 |
20100103099 | POINTING DEVICE USING CAMERA AND OUTPUTTING MARK - Pointing device like mouse or joystick comprises camera for capturing the display screen and image processing means for recognizing and tracking the pointing cursor icon or mark from the captured image and producing the pointing signal. The pointing device of present invention can be used with any type of display without and additional tracking means like ultra sonic sensor, infrared sensor or touch sensor. The pointing device of present invention includes mark outputting portion, camera portion for capturing the said mark outputting portion and image processing portion for recognizing the said mark outputting portion from the captured image and producing the pointing signal. | 04-29-2010 |
20120319949 | POINTING DEVICE OF AUGMENTED REALITY - The present invention relates to a pointing device capable of inputting a particular position of augmented reality to a computer. The invention comprises: a camera which takes a picture of a feature point or a mark used to generate an augmented reality image; and an imam processor which recognizes the feature point or the mark taken by the camera, and outputs position information indicative of a particular position in the augmented reality. Mouse cursor images can be synthesized as augmented reality images at the position outputted from the image processor. | 12-20-2012 |
