Projector interaction refers to handwriting, gesture control and labeling on the projection screen by using a special capacitance pen or laser pointer. It can not only display our operations on the screen in real time, but also interact and cooperate in real time. In teaching, demonstration, conference and other occasions, projector interaction technology can greatly improve the efficiency and quality of communication and meet the needs of modern people for efficiency, convenience and dynamics.

Interactive projector technology has the advantages of simplicity, convenience, real-time interaction, sustainability and long service life. Compared with the traditional projector and LCD screen, projector interaction technology is more flexible and diverse, which can realize the function of writing or drawing by many people at the same time, and the work efficiency and learning effect are relatively higher. Moreover, the interactive projector equipment is simple to operate, movable and reusable, which not only saves the waste and loss of traditional paper teaching, but also helps to protect the environment and save resources.

Application Scenarios and Prospects of Projector Interaction

With the continuous updating of science and technology and people's constant pursuit of quality of life, projector interaction technology has been widely used in education, training, business and other fields. In the field of education, projector interactive technology makes the teaching content more flexible and easy to understand, and increases students' participation and interest. In the commercial field, projector interaction technology has also become an essential tool for display, meeting and publicity. In the future, with the continuous progress of technology and the expansion of application scenarios, projector interaction technology will have a broader application prospect.
