Jumping-At-Air: Jumping without Touching the Ground in Virtual Reality

We propose Jumping-At-Air, where the avatar jumps in the virtual world and lands at a higher air while the user jumps in the real world, then jumps again from the air. The core idea is to first create a pair of pressure-sensing shoes based on the ESP32 chip, equipped with pressure sensors in the soles, to accurately detect the jumping stage. Then, through a carefully designed equation with two adjustable parameters, the user’s jump trajectory in the real world is redirected to drive the jumps of the avatar in the virtual world. The redirected jumping curve is differentiable and continuous throughout its domain and conforms to the definition of a parabola.
