portable whiteboard on wheels. The principle of ultrasonic technology is to calculate the distance from the transmitting point to the receiving point according to the characteristics of the slow transmission speed of the ultrasonic wave according to the ultrasonic transmission to the receiving time. The principle of using the planar positioning is to place two ultrasonic receiving devices distributed at a fixed distance on one side of the screen, and the pen for positioning is an ultrasonic transmitter, and the ultrasonic wave emitted when the pen moves on the surface of the screen It is detected by the receiver along the surface of the screen, and the distance between the pen and the two receivers can be converted by the time of receiving the ultrasonic waves. The principle of three-point positioning is adopted, that is, according to the three side lengths of the triangle, the apex principle of the pen can be determined, and the position coordinates of the pen are calculated. It is a ranging positioning mode.

It is a ranging positioning mode.. The IQAio GR519 is an upgraded lightweight version based on the original IQAio GR511. The original dual-cavity structure was changed to a bottom-edge structure, so that the minimalist design accommodates modern classrooms and conference rooms. With one IQProjector V2 and one IQView E3821, you can achieve flexible and intelligent classroom.

IQAio highly integrated multi-point infrared interactive whiteboard, central control system, wireless microphone, stereo amplifier system, OPS and other equipment.

The uniquely designed IQUSB interface supports one-line connection to external PC equipment. It supports intelligent switching of interactive whiteboards, audio, PPT turner and other internal integrated devices, without additional wiring to meet the needs of various teaching scenarios.

IQAio adopts capacitive touch button, scan RFID card to power on/off device and front button indicator to show the status of teaching operations. That improves the operation experience and very easy to use.

15 soft hotkeys on the both sides and
clear function classification greatly improve the efficiency of use.
