Intelligent learning table based on motion sensing technology

Technical Field

The invention relates to the field of intelligent chemical learning tools, in particular to an intelligent learning table based on a motion sensing technology.

Background

The study table is an indispensable learning tool for primary and secondary school students, and influences the learning efficiency of the students to a certain extent. Traditional study table does not have other functions, and only a few simple panels are spliced to form, on the one hand sit for a long time and study and let primary and secondary school student produce tired easily, on the other hand some problems appear easily when using, for example the desk needs adaptability to be adjusted sometimes, this is to primary and secondary school student comparatively difficult, and is very inconvenient under the condition of not having the head of a family.

The motion sensing technology (motion sensing control) means that people can directly use limbs to move and interact with peripheral devices or environments without using any complex control equipment, and people can interact with contents in the way of seeing the situation. As early as 2005, Sony introduced an optical sensing suite, EyeToy, which acquired human body images mainly through optical sensors and interacted the body movements of the human body images with the contents of the game, mainly based on a 2D plane, but the contents also belong to a simpler type of interactive game.
