Head Mounted Display Power Mode Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays face challenges in efficiently managing power consumption based on the presence of interactable objects within their field of view, as they often operate in fixed power modes regardless of usage, leading to unnecessary battery drain when no interactable objects are present.
Innovation Solution
Implementing a power mode transition mechanism that dynamically adjusts the display's power consumption based on the presence of interactable objects within the field of view, switching to a higher power mode when an object is detected and reverting to a lower power mode when it is not, by utilizing sensors and user interface indicators to determine object presence and user intent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the head mounted display operates in a fixed high power mode to ensure full functionality, then user interaction capabilities are maintained, but battery life is reduced due to unnecessary power consumption when no interactable objects are present
Solution Approach 1:
The system dynamically transitions between first and second power modes based on the detection of interactable objects. When an interactable object is detected within the field of view, the system switches to the second power mode (higher power consumption) to enable full interaction capabilities. When no interactable object is present, the system switches to the first power mode (lower power consumption) to conserve battery life. This dynamic adaptation resolves the contradiction by making power consumption contingent on actual usage needs rather than maintaining a fixed high-power state.
2Use of energy by moving object
If the head mounted display uses sensors to detect interactable objects and dynamically switch power modes, then power consumption is optimized, but device complexity increases
Solution Approach 1:
The system employs a feedback mechanism where sensors continuously monitor the environment for interactable objects within the field of view. Based on this feedback, the system automatically transitions between power modes without requiring user intervention. The presence or absence of detected objects triggers相应的 power mode changes, creating a closed-loop control system that optimizes power consumption while managing complexity through automated decision-making rather than manual control.
3Adaptability or versatility
If the system transitions to a higher power mode when an interactable object is detected, then user interaction capabilities are enhanced, but immediate power consumption increases
Solution Approach 1:
The system uses periodic sensing and conditional power mode transitions rather than continuous high-power operation. The sensors periodically check for interactable objects, and power mode changes occur only when needed. This periodic action pattern allows the system to maintain enhanced interaction capabilities when objects are present while avoiding sustained high power consumption, effectively managing the trade-off between adaptability and instantaneous power usage.

AI summary
A method comprising determining that an interactable object is within a field of view of a head mounted display while the head mounted display is operating in a first power mode, and transitioning the head mounted display from operation in the first power mode to operation in a second power mode based, at least in part, on the determination that the interactable object is within the field of view, such that the head mounted display consumes more power during operation in the second power mode than during operation in the first power mode is disclosed.
