Problems solved by technology

However, for writers, using this adjustment method is to adjust the overall backlight brightness of the touch whiteboard, so it is unavoidable that there is a large area of ​​fixed background color on the touch whiteboard, and the background brightness and contrast are relatively large. Fixed phenomenon, it cannot solve the problem of visual fatigue of writers

Abstract

The present invention provides an adjustment method and device for a touch whiteboard. The method includes the following steps that: when touch operation is recognized, a visual attention area is determined on the touch control whiteboard according to the touch position of the touch operation on the touch whiteboard; and the display parameters of the visual attention area are adjusted according toa preset adjustment manner, so that the display effect of the visual attention area can be adjusted. With the method adopted, the dynamical local adjustment of the touch whiteboard can be realized according to the writing state of a writer on the touch whiteboard, so that the visual comfort of the writer can be improved.

Description

technical field [0001] The present application relates to the field of touch technology, in particular to a method and device for adjusting a touch whiteboard. Background technique [0002] With the rapid development of touch technology, writing operations on touch whiteboards have been widely used in many fields such as teaching and office work. When using touch whiteboards in these fields, it mainly involves the writer and the viewer watching the text for a long time. In the application scenario displayed, in this application scenario, since there is a large area of ​​fixed background color on the touch whiteboard, and the background brightness and contrast are relatively fixed, it is easy to cause visual fatigue for writers and viewers. [0003] In the prior art, the brightness of the overall backlight of the touch whiteboard is usually adjusted by means of adjusting the overall backlight. However, for writers, using this adjustment method is to adjust the overall backli...
