TACTILE-TYPED INFORMATION INPUTTING SYSTEM FOR VERY SMALL INFORMATION DEVICE USING FINGER AND DEVICE THEREOF

摘要

PURPOSE: A tactile-typed information inputting system for a very small information device using a finger and a device thereof are provided to operate more precise information input by offering feedback through tactile sensation of the finger, as a finger tip of a user gets to a pad, and recognize normal movement of the finger without seeing the movement through an eye or a screen. CONSTITUTION: A transparent plate(211) is equipped with a small projection(212) for easily touching with the finger tip and recognizes information input feedback through the tactile sensation of the finger. A lens(213) formed to a lower part of the plate collects an image recognized by the plate. A CMOS(Complementary Metal Oxide Semiconductor) image sensor(214) formed to the lower part of the lens generates the current image and motion vector information of the finger passing the lens. A switch button(215) transfers information by being pushed by the finger in order to process a user's command. The information is inputted by the movement for pushing or leaving from the projection.
