Embodiment Construction

[0028] Such as figure 1 As shown, an air mouse applied to an interactive electronic whiteboard of the present invention has a cylindrical casing on the outside, the front end of the casing is tapered, and the entire casing looks like a pen. A laser head 1 , a power control module 2 , a photoelectric rotary encoder 3 , a wireless signal sending module 4 and a power supply 6 are installed in the casing. The laser head 1 is arranged at the front end of the casing, inside the cone, and the output of the power control module 2 is respectively connected to the laser head 1 and the wireless signal sending module 4 . The laser head 1 has two stable working states of weak light and strong light, and its working state is controlled by the power control module 2 .

[0029] The power supply 6 is connected to the power switch 5, and the power switch 5 extends out of the housing. The laser head 1, the photoelectric rotary encoder 3 and the wireless signal transmission module 4 are respect...

Abstract

The invention discloses an air mouse applied in an interactive electronic whiteboard of multimedia teaching devices. The air mouse comprises a housing; a laser head, a power control module, a photoelectric rotary encoder, a wireless signal transmitting module and a power supply are installed inside the housing. The power supply is connected with the laser head, the photoelectric rotary encoder and the wireless signal transmitting module through a power supply switch; the output end of the power control module is connected with the laser head and the wireless signal transmitting module; the output end of the photoelectric rotary encoder is connected with the wireless signal transmitting module; part of a pulley is positioned inside the housing and the other part of the pulley protrudes from the housing to the outside; the resistance value of the power control module increases or decreases by rotating the pulley; the laser head has a weak light work state and a strong light work state; the moving status of the pulley is detected and encoded by the photoelectric rotary encoder; detected and encoded signals are sent by the wireless signal transmitting module in the form of wireless signals; only a pulley is used as a function key which makes the air mouse flexible to operate; by means of the air mouse, writing and drawing can be performed remotely and in a contactless mode.

Description

technical field [0001] The invention relates to an electronic whiteboard (projector system) in multimedia teaching equipment, in particular to an air mouse used for an interactive electronic whiteboard. Background technique [0002] The teaching equipment has gradually changed from the combination of chalk and blackboard to the combination of laser pointer and electronic whiteboard (projection system). Laser pointer and electronic whiteboard have been widely used, but in the process of multimedia teaching, laser pointer and electronic whiteboard cannot be used flexibly. The main performance is the lack of functions, the human-computer interaction cannot be fully realized, and the real-time operation cannot be fully realized. [0003] Now there are two directions for improving the whiteboard system. The first direction is to improve the whiteboard, which is generally called a touch whiteboard, and the second direction is to improve the laser pointer, which is generally called...
