Here, we discuss the way through which we can capture the lower body movements of the body, with a simple Bluetooth device. The device will have a liquid or water bubble in it, which when worn on shoes, will track the movement of the lower body, with the help of AI on the (VR/AR/MR) device. Introduction Today, Virtual Reality/ Augmented Reality/ Mixed Reality has come a long way from earlier techniques using motion controllers for hand movement tracking. Nowadays, we use hand tracking which comes inbuilt with (VR/AR/MR) devices. These devices use the camera built in the (VR/AR/MR) devices to capture the image of the hand movements and track it. The problem with this method is it can't track the lower body movements. The camera in the (VR/AR/MR) devices, which is worn on the head can't have a view of the lower body. So, if we use motion controllers in the lower body, instead of cameras in the (VR/AR/MR) devices to capture the movement of the lower body, the ...
