A human-computer interaction platform

Abstract

The invention discloses a human-computer interaction platform, comprising: an operation box, a projection cloth, and a playback box, wherein a wireless signal structure is installed on the operation box, projection cloth, and playback box, and the playback box is installed on the On the classroom ceiling, the projection cloth is installed on the classroom ceiling through a horizontal moving structure, an angle adjustment structure is installed on the playing box, and a human face acquisition structure and an operation angle adjustment structure are installed on the operation box; The arc rotation structure and the angle adjustment structure change the horizontal and vertical angles of the projection equipment. According to the changed angle, the angle of the projection cloth is adjusted through the horizontal movement structure to meet the projection requirements. At the same time, according to the face acquisition structure and light sensor detection The output data, change the projection angle and the angle of the projection cloth, so as to meet the needs of most users, and perform air pressure cleaning on the projector through the cleaning structure, which has a simple structure and strong practicability.

Description

technical field [0001] The invention relates to the technical field of intelligent teaching, in particular to a human-computer interaction platform. Background technique [0002] The projector is an optical instrument that uses optical components to enlarge the outline of the workpiece and project it onto the screen. It can use transmitted light for profile measurement, and can also use reflected light to measure the surface shape of non-through holes and observe the surface of parts. The projector is especially suitable for measuring complex contours and small workpieces, such as clock parts, stamping parts, electronic components, templates, molds, threads, gears and forming tools, etc. Especially suitable for the instrumentation and watch industry. [0003] The angle of the existing projector is fixed during use. When the projector is inclined, the user needs to manually move the position, which is inconvenient for the user to use and reduces the practicability of the sm...

Problems solved by technology

[0003] The angle of the existing projector is fixed during use. When the projector is tilted, the user needs to manually move the position, which is inconvenient for the user and reduces the practicability of the smart projector. In view of this, After in-depth research on the above problems, this case came into being
