The non-contract selecting device include a light source, emitting light to an outside; a camera unit, generating and outputting a video signal corresponding to an external video; a video data generating unit, generating video data corresponding to the video signal; and an identity unit, detecting a location of a detected area formed by light, reflected by pointing-means and inputted, of the light emitted from the video data in units of each frame, recognizing a moving locus of the detected area by comparing at least two continuous frames and generating and outputting corresponding change information. With the present invention, the function-selecting can be more quickly and easily and increase making the most use of elements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-contact selection device","description":"A non-contract selecting device is disclosed.
