Design of VR Extension Device Based on Motion Capture Tracker and Data Glove
The emergence of the metaverse has necessitated enhanced interactive experiences with virtual devices,leading to increased demands for virtual reality applications.A VR expansion device that utilizes motion capture trackers and data gloves is proposed.Motion capture trackers collect inertial sensors(IMU)to obtain posture data on the chest,waist,and legs.The data glove collects the voltage of the limiter to obtain the curvature of the five fingers.The system uses ESP32 as the main control and FreeRTOS embedded real-time op-erating system.Each terminal communicates with PC through Wi-Fi and Bluetooth protocol.Data is connected to Open source VR sys-tems such as SlimeVR Server and Open Gloves to generate 3D models and restore human actions in virtual environments.At the same time,ESP32 obtains the finger-limit data and outputs PWM signals to control the steering gear,realizing the VR force feedback body sensing glove finally.Each lower machine terminal has a perfect debugging interface and power supply design.Each device is modeled and 3D printed using Solidworks software.With the support of open-source projects,this design facilitates the tracking of various body parts,including the waist,legs,feet,and fingers on existing home VR headsets and accompanying positional controllers.Consequently,it enables comprehensive full-body tracking within virtual reality software,thereby augmenting the interactive capabilities of virtual de-vices.
