Electronic whiteboards generally do not have a touch screen. There are two cases.
First, you mean that the board of the electronic whiteboard has no sensing function. If the electronic whiteboard you use is one of electromagnetic, infrared or pressure sensing, and the hardware problem of the board is excluded, the common problem may be the driver. Not installed or not connected successfully. For three different sensing technologies, the electromagnetic whiteboard also checks whether the electromagnetic induction pen is sensitive and easy to use. The infrared whiteboard also insists on whether the frame infrared transmitting and receiving device is covered or not.
Second, if the "electronic whiteboard" you use is an interactive LCD, it is generally infrared-sensitive, which is consistent with the above method.
We are the manufacturer of interactive whiteboards and interactive LCDs. We can communicate with you in this regard!
