Method and equipment for making interactive operation with display system

Abstract

This invention discloses a method and equipment for interacting with display systems, in which, the method includes that before an operator holding a near-infrared polarized light emitter enters into the screen of a display system, a computer displays an interaction interface on the screen and the emitter contacts with the screen and emits orders, an imager collects images on the screen and an image processor computes the facular position of the polarizer and receives its orders to code and transmit them to the computer, which interacts with the display system based on the position and order information. The equipment includes a display system, a computer, an imager, an image processor and a near infrared polarized light emitter.

Description

technical field [0001] The invention relates to a method and equipment for human-computer interaction, in particular to a method and equipment for interactive operation with a display system. Background technique [0002] As an auxiliary means of interacting with computers, display interaction has become one of the fields that are widely concerned at present. From the fields of teaching, conference and entertainment, the display interaction system plays an increasingly important role. In teaching, projectors are traditionally used as display devices. Before teaching activities, teachers should prepare the scripts to be spoken and display the files in class through computers. There are several problems in this way: First, the teacher may be negligent or omission when writing the lecture. Because editing needs to be operated by computer and normal teaching needs to be interrupted, it is impossible to correct the deviation in time; second, the teacher may need a platform simi...

There are several problems in this method: First, the teacher may be negligent and omit when writing the lecture

However, the disadvantages of this method are: first, the response speed is slow, and the signal generated by the ultrasound is processed through signal filtering, shaping, amplification, etc., and then the position information is calculated; The coordinate position, the installation position and angle of the ultrasound equipment need to be manually registered, and this process generally takes a long time; third, the equipment requires relatively expensive hardware costs, which mainly requires a strong signal processor ; Fourth, the device is sensitive to environmental noise. If there is a frequency close to the ultrasonic frequency in the environment, ultrasonic positioning will become unreliable
