1,Principle and mechanism

IR:Ordinary IR touch frame uses infrared emitting tube to emit infrared light, and forms an optical net above the touch frame. When the finger and other objects touch the screen to block part of the infrared light, the receiving tube detects the change of light intensity to determine the touch position. The principle is more basic and direct.

Smart IR:Smart IR is also based on infrared light emission and reception, but on this basis, an intelligent processing unit is added. It can carry out intelligent analysis and processing of the received light signal, such as the use of intelligent algorithms to optimize the touch detection process, not only simple judgment of light intensity changes, but also more in-depth interpretation of touch action related information.

2,Environmental adaptation

IR:Ordinary ir touch overlay is greatly affected by ambient light. In a strong light environment, such as outdoor direct sunlight or indoor strong light exposure, the infrared component in the ambient light is easy to interfere with the infrared light emitted and received by itself, resulting in a decline in touch accuracy and the possibility of misjudging the touch position.

Smart IR:The intelligent IR infrared touch box can sense the ambient light condition through the intelligent light sensor. Once the interference is detected, its built-in intelligent algorithm will automatically adjust the infrared transmission power, receiver tube sensitivity and other parameters, effectively reduce the ambient light interference, so that the touch box can still work stably and accurately in complex lighting environment.

3,Touch precision

IR:Ordinary IR touch overlay has limited touch accuracy and mainly relies on simple light intensity changes to determine the touch position, which is insufficient for subtle touch action discrimination. For example, when performing fine drawing operations, it may not be possible to accurately present the line direction, which is difficult to meet the requirements of high-precision touch.

Smart IR:Intelligent infrared touch box with advanced multi-touch recognition technology and intelligent calibration algorithm, can locate the touch point more accurately, can accurately distinguish between adjacent touch points, touch accuracy is greatly improved, can be a good response to professional drawing, precision design and other application scenarios with high accuracy requirements.

4,Function expansion

IR:The function of ordinary infrared touch box is relatively single, and most of them can only realize single touch operation. It is difficult to support complex gestures such as two-finger zoom and three-finger switch applications, which limits the richness of interaction methods.

Smart IR:The intelligent infrared touch box has a strong ability to expand functions. In addition to supporting a single touch, it can also accurately identify a variety of complex gestures, such as two-finger zoom, three-finger switch application, multi-finger rotation, etc., which greatly enriches the interaction experience between users and devices.

In general, intelligent IR has obvious advantages in many aspects compared with ordinary IR in the application of infrared touch box, which can better adapt to different scenarios and meet the diverse interaction needs of users.
