Abstract
A coordinate detection system includes a coordinate detecting apparatus that is mounted on a display apparatus, detects approach of an indicating object toward the display apparatus, detects a position coordinate of the indicating object on the display apparatus, and outputs a notice indicating the approach of the indicating object and the position coordinate; a contact detecting apparatus that detects whether the contact detecting apparatus is in contact with the coordinate detecting apparatus and outputs a notice indicating contact or non-contact of the contact detecting apparatus; and an information processing apparatus that includes a control unit that, upon reception of the notice indicating the approach of the indicating object, determines whether the notice indicating the contact of the contact detecting apparatus is received within a predetermined time, and issues an event indicating the contact of the contact detecting apparatus when receiving the notice of the contact of the contact detecting apparatus.
