VR Apparatus Rotating Base for Head Body Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality systems are limited in tracking user movement, particularly failing to reliably determine the direction a user is looking and facing simultaneously, leading to disorientation and nausea due to mismatched visual and vestibular sensations, and are constrained by cables that restrict movement.
Innovation Solution
An apparatus with a first and second base part that rotate relative to each other about a common axis, using a foot-operated or wearable user input to control rotation, and means to determine the angle between these parts, allowing independent tracking of head and body movements, and incorporating a camera to monitor hand movements, thus providing a more immersive and unrestricted experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera is used to monitor user movements in virtual reality, then the ability to track body direction is improved, but the ability to simultaneously track head direction and hand movements is compromised
Solution Approach 1:
The system divides the tracking function into multiple independent sensors: a camera for body direction, a head tracker for head orientation, and hand trackers for hand movements. Each sensor independently monitors a specific body part, allowing simultaneous tracking of multiple movement parameters without mutual interference.
Solution Approach 2:
The controller is designed to receive and process inputs from multiple types of sensors (camera, head tracker, hand tracker), making it a universal input system that can handle various movement parameters from different body parts through a single integrated controller.
2Adaptability or versatility
If visual representation of movement is provided without corresponding physical movement detection, then user immersion is improved, but disorientation and nausea occur due to vestibular-visual mismatch
Solution Approach 1:
The system continuously monitors actual user movements through multiple sensors and provides real-time feedback by adjusting the virtual environment accordingly. This closed-loop feedback ensures that visual representations of movement correspond to actual physical movements detected by the sensors, preventing vestibular-visual mismatch.
3Stability of the object's composition
If cables are used to connect the headset to the controller, then system stability is improved, but user movement freedom is restricted
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The headset and controller communicate wirelessly, eliminating the physical cable constraint while maintaining system functionality and stability through wireless signal transmission.

AI summary
An apparatus for virtual reality simulation includes a first base part and a second base part arranged to rotate relative to each other about a common axis. The apparatus also includes means for determining an angle between the first base part and the second base part. The second base part may be provided with a chair on which a user of the apparatus may sit during use of the apparatus. The means for determining an angle between the first base part and the second base part enables the apparatus to determine the direction in which the user is facing, relative to the first base part, after relative movement of the first base part and the second base part.
