Abstract

The invention discloses a multimedia teaching device, especially relating to an electric blackboard. The electric blackboard comprises a touch display screen and a computer. The touch display screen connects with a host machine of the computer, and is used for converting a touch locus on the touch display screen into an electric signal and sending the electric signal to the host machine of the computer. According to the electric signal, the host machine of the computer identifies the touch locus and displays the touch locus on the touch display screen. The electric blackboard uses a traditional mode of using a chalk and a blackboard for teaching, damage to a teacher body by dust pollution is avoided, in addition, a finger, a pen or any object capable of blocking light can be employed to carry out touch control operations of writing, erasing or modifying and the like, and usage of the electric blackboard is simple and efficient.

Description

technical field [0001] The invention relates to a multimedia teaching device, in particular to an electronic blackboard. Background technique [0002] The use of chalk and a blackboard format for teaching lessons has long held a very important place in the field of education. It not only has the advantage of low teaching cost, but also the teacher's vivid lectures and graphic illustrations or explanations on the blackboard can greatly improve students' attention and thus improve learning efficiency. [0003] However, with the development of science and technology and people's deeper understanding of certain diseases, the disadvantages of traditional chalk teaching have gradually attracted attention. For example, the chalk dust produced by chalk when writing and wiping, its main component is calcium sulfate or calcium carbonate. Inhalation into the trachea will cause discomfort in the nose, pharynx, and throat. If you stay in this environment for a long time, you are more l...
