Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional motion capture systems use multiple cameras and markers, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and removes the markers and fixed sensors from the motion capture system, using only the wearable device's own sensors to capture motion. This eliminates the need for external cameras and markers while maintaining measurement capability through inertial measurement units and wearable sensors integrated directly into the device.
Solution Approach 2:
The wearable device performs multiple functions including motion capture, gesture recognition, and environmental sensing using a single integrated sensor system. The same sensors that track device orientation and position are also used to detect user gestures and capture environmental data, eliminating the need for separate dedicated motion capture equipment.
2Measurement precision
If conventional motion capture systems use multiple cameras and markers, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
By removing markers and fixed sensor infrastructure, the system becomes portable and requires no special environment setup. Users simply wear the device and begin capturing motion immediately without requiring calibration of external cameras or placement of markers in the environment.
Solution Approach 2:
The wearable device autonomously captures and processes motion data using its own integrated sensors without requiring external equipment or complex setup procedures. The device self-calibrates and processes gestures independently, eliminating the need for operators to configure external camera systems or manage marker placement.
3Adaptability or versatility
If the system integrates multiple sensor types (RGB and IR pixels), then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent combines RGB and infrared sensors into a single integrated sensor module within the wearable device. Both sensor types share common processing circuits and data pathways, allowing the system to capture both visible light and thermal/infrared information simultaneously without requiring separate independent sensor systems.
Solution Approach 2:
The integrated sensor system serves multiple functions including gesture recognition, environmental mapping, and motion tracking. The same sensor array detects both color information from RGB pixels and thermal or depth information from IR pixels, enabling the device to adapt to various detection scenarios without adding separate dedicated sensor subsystems.
Data Source
AI summary
The technology disclosed relates to user interfaces for controlling augmented reality (AR) or virtual reality (VR) environments. Real and virtual objects can be seamlessly integrated to form an augmented reality by tracking motion of one or more real objects within view of a wearable sensor system. Switching the AR/VR presentation on or off to interact with the real world surrounding them, for example to drink some soda, can be addressed with a convenient mode switching gesture associated with switching between operational modes in a VR/AR enabled device.
