A projector that can interact by touching the wall with your hand, an optical fiber that does not heat up and leak electricity under water...

In front of the booth of the Changshou Economic Development Zone of the Smart Expo, many citizens surrounded these "black technology" products and played "hi".

This is a hand-touch interactive projector developed by Chongqing Dazong Optoelectronics Co., Ltd. Citizens can perform touch operations on the projection wall with bare hands without any media and tools. It is easy to operate various entertainment activities such as chess and cards, video and audio.

According to the person in charge of the scene, this is an interactive projector through laser induction. In addition to the projector itself, it is only necessary to install two laser induction devices at the upper and lower ends of the projection range to achieve manual interaction.

"Our lighting system, because it uses optical fiber material, completely avoids potential safety hazards." In front of a "plastic optical fiber underwater lighting system", the reporter saw fish roaming in the tank, and the optical fiber beside it. Lighting makes the whole tank more interesting.

The on-site staff introduced that because it is fiber optic lighting, it has the characteristics of non-conductive and non-heating, and is more suitable for some underwater application scenarios, thereby preventing safety hazards such as leakage.
