Problems solved by technology

At present, the above-mentioned indoor space is mainly projected using a front projection device, that is, the image is projected on the projection surface from the front of the screen or other projection surface. The traditional front projection device needs to control the playback of files through a mouse, keyboard or other input devices. For example, another person needs to be dedicated to the operation of the mouse and keyboard

Abstract

The invention provides a front projection control method which is applied to a front projection device. The device is connected to a camera. The method comprises the following steps of: setting three gestures, wherein each gesture corresponds to an operation key of a mouse; when an opened file is projected to a projection curtain, and receiving scene images of a file interpreted by a user of the camera; identifying whether the gesture of the user in the scene image is same as a set gesture or not; when the gesture identified in the scene image is the same as the set gesture, tracking the tip of an index finger of the user; and projecting a vernier at the tip of the index finger of the user, and executing the function of the operation key of the mouse corresponding to the set gesture according to the identified gesture. The invention further provides the front projection device. By the method and the device, the functions of various operation keys of the mouse can be simulated.

Description

technical field [0001] The invention relates to a front projection device and a front projection control method thereof. Background technique [0002] Indoor spaces such as classrooms, venues, lecture halls, and auditoriums are important places for people to carry out collective activities. With the increase of indoor space, projection devices have gradually become an indispensable tool to provide students, participants, and audiences with another A "blackboard" makes up for the defects caused by the large space to some extent. At present, the above-mentioned indoor space is mainly projected using a front projection device, that is, the image is projected on the projection surface from the front of the screen or other projection surface. The traditional front projection device needs to control the playback of files through a mouse, keyboard or other input devices. For example, another person needs to be specially responsible for the operation of the mouse and keyboard. Co...
