Abstract

The embodiment of the present invention discloses a method and device for annotating display content. The method includes: the main control chip of the interactive device receives the display data sent by the data source and performs corresponding display; the touch screen of the interactive device detects the touch track corresponding to the annotation , the main control chip generates a transparent layer with the touch track; the main control chip superimposes the transparent layer on the display screen corresponding to the display data for synchronous display. In the embodiment of the present invention, the main control chip of the interactive device receives the display data sent by the data source, generates a transparent layer with a touch track according to the touch track corresponding to the annotation detected by the touch screen, and synchronously displays the transparent layer on the display screen, When the display screen needs to add annotations, the main control chip will add them according to the touch detection results, which eliminates the impact of different types of data sources and access methods on annotations, and can annotate various display screens to improve interaction. The intelligence of the device.

Description

technical field [0001] Embodiments of the present invention relate to the field of smart terminals, and in particular, to a method and device for annotating displayed content. Background technique [0002] With the rapid development of smart terminals, smart interactive tablets have gradually become the main force of education informatization. [0003] The intelligent interactive tablet is an integrated device that controls the content displayed on the display panel and realizes human-computer interaction operation through touch technology, and brings people a new experience through interactive behavior. At present, intelligent interactive tablets have been popularized in conference rooms and classrooms, and the annotation function will be used in PPT playback. In order to improve the convenience of after-sales use and service processes such as product maintenance and software and hardware upgrades, the existing intelligent interactive panels often integrate the basic funct...
