AI Technical Summary

Problems solved by technology

However, the existing electromagnetic interactive surface technology has not yet provided a technical solution that meets all the requirements of users.
Since the display area of ​​the electronic whiteboard is significantly larger than that of ordinary monitors, the presenter needs to move in a large range when operating the controls in the demonstration interface. For operations that require temporary adjustment of the display mode to emphasize part of the display content, repeatedly through the menu , buttons and other controls to change the display mode will take too much time for the presentation, and may distract the audience's attention and affect the presentation effect

Embodiment Construction

[0032] Such as figure 1 As shown, the interactive display system includes a whiteboard 10 in communication with a computer 14 . The projector 12 receives the signal from the computer 14 and translates it into a corresponding projected image and projects it on the whiteboard 10 . The image projected on the whiteboard 10 is the same as the display on the computer screen. The position of the indicator 11 can be electronically detected by a plurality of circuits embedded under the surface of the whiteboard 10, and it can function similarly to a computer mouse by the method described above. Another alternative is that the whiteboard could be a resistive type so that the presence of the pointing device could be sensed in the form of pressure that would press the two layers together at a location where it would be sensed. Another alternative is to use a laser pointer. When the laser pointer hits the light spot on the whiteboard, it will be reflected back to the laser pointer by th...

Abstract

The invention discloses an interactive display system with an emphasis mode. An image displayed by the interactive display system has a first display area in a common display mode and a second display area in an emphasis display mode. An indicating device can control a calculating device to open or close the second display area. Therefore, the display system provided by the invention is simple and practicable, has the emphasis mode, cannot divert attention of audiences and has excellent demonstrating effect.

Description

technical field [0001] The present invention relates to interactive display systems, and more particularly to an interactive display system with an emphasis mode. Background technique [0002] Interactive displays in the prior art use an electronic whiteboard to sense the position of an electronic pen on its surface. After the computer display is placed on the whiteboard and its position is corrected, the computer display can be manipulated by manipulating the electronic pen to write on the whiteboard, just like using a computer mouse. The use of this interactive whiteboard, which enables teachers to quickly process and annotate material in response to audience questions, improves teaching efficiency while enhancing student understanding. This whiteboard enables the adoption of high-quality digital teaching materials, as well as the use of sound and visual technology for data processing and presentation. [0003] A typical construction of an electronic whiteboard includes ...
