Wearable Device Power Save Mode via Orientation and Audio Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional AR/VR wearable devices have shorter battery life due to design limitations and increased power consumption, continuing to consume power even when not actively in use, with existing solutions requiring manual interaction or gaze detection that may not accurately determine device inactivity.
Innovation Solution
Implementing sensors to identify the orientation of a wearable device and determine if it is in an active or inactive position, combined with environmental audio analysis to provide power save options, allowing the device to dynamically switch to sleep or power off modes based on context and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the wearable device continues to consume power even when not actively in use, then the device remains ready for immediate use, but the battery life is reduced
Solution Approach 1:
The system performs preliminary detection of device orientation and user presence before transitioning to power save mode. Sensors detect whether the device is in a pocket or bag orientation, and if no user presence is detected, the system proactively transitions to a lower power state, preparing for power conservation before the user would naturally notice the power consumption issue.
Solution Approach 2:
The system dynamically adjusts its power state based on real-time sensor data. Instead of a static power consumption mode, the device transitions between active and power save states based on detected orientation and user presence, optimizing power consumption while maintaining readiness when needed.
2Extent of automation
If manual interaction or gaze detection is used to determine device inactivity, then the device can switch to power save mode, but the solution requires user interaction or may not accurately determine inactivity
Solution Approach 1:
The system uses sensors as intermediaries to detect device orientation and user presence. Rather than relying on direct user input or gaze detection, the sensors indirectly measure physical conditions (orientation, proximity) that correlate with user presence, providing a more reliable automated detection mechanism that works even when the user is not actively interacting with the device.
Solution Approach 2:
The device monitors its own state through integrated sensors, automatically determining when it should transition to power save mode without requiring external user input. The system serves itself by detecting its own orientation and the absence of user presence, making autonomous decisions about power management.
3Loss of energy
If the device uses sensors to detect orientation and provide power save options, then power consumption is reduced, but the device complexity increases
Solution Approach 1:
The sensors integrated into the wearable device serve multiple functions: they detect device orientation for power save determination, track user presence, and potentially support other device functions. By making the sensors multi-functional, the patent reduces the need for additional dedicated components, thereby limiting the increase in device complexity while achieving power conservation goals.
