Large screen and high-precision frameless touch control scheme in conference room

  What have we solved Laser touch technology turns various large screens into large touch screens with high precision, large picture and no frame, which can realize: large picture touch projection, touch LED screen and touch splicing screen Product core advantages: large picture: up to 3 * 36 meters, fast speed: products above 120 inches are 2-3 times the response speed of infrared frame, high precision: positioning accuracy of 2mm, which can achieve writing accuracy No border: no border, more beautiful Technical parameter setting of large screen scheme 1 in conference room , Bit: automatically correct the number of touch points: ten points (multiple pens are required for pen touch) delay , When: & le; 30ms push-pull mode: the software automatically controls the push-pull filter to enhance stability
Touch mode: finger touch, pen touch, laser imaging technology (lict) positioning accuracy: the deviation is less than 2 pixels, projection ratio: 0

The palm stays for 1 second
Sliding is to move the window 9 Ten fingers open and slide down to minimize all windows 10, tap the palm twice to return to the computer desktop 11, wipe the palm 12
In any non writing state, switch to the writing state and double-click with one finger , 13
Palm hold for 2 seconds spotlight Principle of laser imaging technology (lict) , An infrared laser module is installed on the board or wall to form an invisible light film 1-2mm higher than the surface and about 1mm thick on the projection surface
When the finger or any opaque object contacts the surface, the light is reflected to an image sensor arranged above the projector, and then the coordinates of the mouse are obtained through the accurate calculation of the photoelectric position http://www
