LiDAR based Smart Wall is a device that can convert any wall into a smart wall. We've seen many large touch screen devices that cost a lot of money, but this one just costs around INR 10K. If you keep the device to the base of any wall and connect the projector, the entire wall becomes a smart wall. All you need to do is 4-point calibration to project your screen and then the screen is controlled by your hand's actions. Then the wall functions as a normal touchscreen device.
