Extended Reality Headset Calibration Using Equipment Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 2D screens on exercise equipment lack immersion and users face issues with orientation in extended reality environments due to a lack of frame of reference in real-world surroundings while using extended reality headsets.
Innovation Solution
A method for calibrating an extended reality headset by identifying physical parameters of exercise equipment, defining an operation space, and presenting a digital control space to align virtual and real-world interactions, allowing users to interact with virtual objects while maintaining orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an extended reality headset is used to provide immersive exercise experience, then immersion and interactivity are improved, but user orientation and spatial reference in the real world deteriorate
Solution Approach 1:
The patent introduces physical markers placed on the exercise equipment as intermediary objects between the virtual reality environment and the real world. These markers serve as reference points that the XR system can detect and use to establish spatial orientation, allowing users to maintain awareness of their physical surroundings while immersed in the virtual exercise environment.
Solution Approach 2:
The system performs preliminary calibration by detecting the position and orientation of physical markers on the exercise equipment before the user begins exercising. This preliminary spatial mapping establishes a reference frame that enables the XR system to correctly orient virtual elements relative to the user's physical position on the equipment.
2Measurement precision
If physical parameters of exercise equipment are calibrated to align virtual and real environments, then user orientation is improved, but system complexity increases
Solution Approach 1:
The patent uses simple visual markers that replicate physical features of the exercise equipment in the virtual environment. These markers are detected by the XR system to create a simplified geometric model of the equipment's spatial configuration, enabling orientation alignment without requiring complex sensing or processing systems.

AI summary
A method calibrates an extended reality headset to be worn by a user for use with a piece of exercise equipment having at least one exercise device. The method includes the step of inputting data identifying physical parameters of the at least one exercise device. An operation space is then identified about the at least one exercise device for the user to occupy while using the piece of exercise equipment. A digital control space is then presented with control inputs allowing the user to control the piece of exercise equipment and/or to control the digital rendering of the extended reality environment. A digital rendition of the piece of exercise equipment and the at least one exercise device is rendered in the view of the user wearing the extended reality headset while operating the piece of exercise equipment.
