INTERFACE DEVICE, PORTABLE DEVICE, CONTROL DEVICE, MODULE, CONTROL METHOD, AND PROGRAM STORAGE MEDIUM

摘要

In order to provide an interface that has input functionality with high recognition precision, this interface device (100) is provided with an imaging unit (110), a control unit (120), and a projection unit (130). The protection unit (130) projects projected video (300). The imaging unit (110) captures video of the area in which the projected video (300) is being projected. If captured video captured by the imaging unit (110) contains both the projected video (300) and a user-input object (400), then on the basis of the relationship between the position of the projected video (300) in the captured video and the position of the user-input object (400) in the captured video, the control unit (120) generates user-input information by recognizing user input being performed using the user-input object (400).
