NON-CONTACT TYPE INPUT DEVICE

摘要

The present invention relates to a non-contact type input device. The non-contact type input device includes a main body having a predefined virtual input space area at one side; a physical display device installed at another side of the main body; at least two cameras installed at the main body to face the virtual input space area and generate a capture image capturing a position or movement of a touch means in the virtual input space area; and an image processing unit for calculating position coordinates of the touch means by analyzing the capture image and converting the position coordinates of the touch means into projected position coordinates on the display device. According to the present invention, without any physical contact with an actual input device, a user may input a key value or signature. Therefore, disease (germs) infection of a user due to an indirect contact in crowded places such as hospitals, banks, marts, and restaurants may be prevented.
