Light guide plate for system inputting coordinate contactlessly, a system comprising the same and a method for inputting coordinate contactlessly using the same
Disclosed are a light guide plate for a non-contact type coordinate input system, a system including the same, and a non-contact type coordinate input method using the same. More particularly, the present invention relates to a light guide plate for a non-contact type coordinate input system, which eliminates inconvenience of a conventional contact-type coordinate input system inputting coordinates through direct contact, and which can reduce use of sensors and optical loss as much as possible. The present invention also relates to a system including the same, and a non-contact type coordinate input method using the same.
