AR Headset Visual Sensor Input Detection Unworn State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality (AR) devices and gaming systems are limited in their ability to interact with the physical world, as they primarily influence virtual environments and lack seamless integration with external displays and user inputs when the headset is not worn.
Innovation Solution
A wearable headset with an optical arrangement and visual sensors that can detect user inputs and adapt visual content, both when worn and when docked, allowing for AR and VR modes, and enabling seamless transitions between internal and external displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the headset is designed to provide AR/VR experiences when worn, then the visual display and optical arrangement are optimized for immersive experiences, but the device cannot effectively interact with or display content on external displays when not worn
Solution Approach 1:
The headset system dynamically changes its operational mode based on whether it is worn or not. When worn, it operates in AR/VR mode with the optical arrangement directing display output to the user's eyes. When not worn, the system detects this state and automatically switches to external display mode, where the same display components output content to external monitors or screens. This dynamic reconfiguration allows a single device to serve multiple functions without requiring separate hardware systems for each mode.
2Adaptability or versatility
If the visual sensors are used to detect user inputs only when the headset is worn, then the sensing system is optimized for head-mounted tracking, but user inputs cannot be detected when the headset is docked or not worn
Solution Approach 1:
The visual sensors in the headset are designed to perform multiple functions depending on the operational state. When the headset is worn, the sensors detect user inputs such as hand gestures or controller positions within the field of view for AR/VR interaction. When the headset is not worn or is docked, the same visual sensors continue to function by detecting user inputs in the environment, enabling the system to maintain input detection capability across different operational states. This multi-functional design ensures reliable input detection regardless of whether the headset is being worn.
3Adaptability or versatility
If the system transitions between worn and unworn states, then the display output can switch between internal and external displays, but the transition may cause disruptions in the user experience
Solution Approach 1:
The system performs preliminary detection of the headset's operational state (worn or not worn) and proactively prepares the appropriate display output configuration before the user actually needs to switch modes. For example, when the headset is placed on a docking station, the system detects this state change and automatically begins routing display output to external monitors, ensuring a seamless transition. This preliminary action prevents disruptions by having the system ready to switch display outputs before the user becomes aware of the state change.
