15-point Laser + Inertial Motion Capture System

Our motion capture system uses laser positioning and inertial fusion to achieve stable and precise capture of full-body and hand movements.

This system is not affected by environmental electromagnetic interference, ensuring stable and reliable motion capture in any environment.
The system has 15 pre-configured wearing positions, making it very convenient for customers without the need for setup. The motion capture algorithm can immediately adapt to bone positions, eliminating the need for additional recognition and calibration, greatly simplifying the motion capture process to ensure smooth and seamless operation.
It can output stable data for a long time, enabling stable operation of motion capture for extended periods.
Based on inverse kinematics and inverse dynamics motion capture algorithms, it provides real-time, precise, and natural motion solution data.
The system includes laser + inertial capture gloves, enabling stable tracking of individual fingers.

Robotic Touch Technology

Force Feedback System

Touch technology has always been a highly sought-after feature to enhance the metaverse experience. However, until now, this technology has been limited by cost and maturity. STEPVR has developed its own tactile system, including a 6-degree-of-freedom robotic arm, tactile gloves, and a vest. The robotic arm provides reverse force in physical interactions, such as opening doors or swinging baseball bats. The gloves simulate tactile sensations when in contact with objects, while the vest is equipped with linear motors to simulate physical touch and collisions. This system allows for a comprehensive tactile experience. STEPVR's in-house development ensures high cost-effectiveness. For example, the cost-effective tactile gloves utilize over 100 dynamic elements, providing high-fidelity tactile sensations.

Omnidirectional Motion System

The omnidirectional motion system is a technology that changes the rules of virtual world games, inspired by the movie Ready Player One. Utilizing orthogonal multi-roller systems, users can achieve arbitrary walking in virtual space on a 1.5-square-meter platform. The system uses low-latency laser positioning technology to accurately identify user movements and seamlessly integrates traditional motor drive control and human motion compensation control with deep learning methods, providing rapid, adaptive response for human motion. It recognizes human motion trajectories and adjusts rollers in 360 degrees to maintain user position.

The system uses low-latency, laser positioning systems to accurately and instantly identify human movements. It seamlessly combines motor drive control and human motion compensation control using traditional and deep learning methods, providing fast and adaptive responses to human movement.
