Wearable Screen State Switching for Power-Aware 3D Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices with augmented reality capabilities do not effectively adapt the state of screens based on user interaction, leading to inefficient resource utilization and increased power consumption.
Innovation Solution
A wearable device equipped with sensors to identify user direction and body part motion, allowing it to switch between different screen states based on interaction permission, enabling three-dimensional rendering and interaction functions dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If three-dimensional rendering is continuously enabled for all screens, then visual quality and user experience are improved, but power consumption increases
Solution Approach 1:
The system dynamically switches the rendering state of each screen between first preset state (three-dimensional rendering enabled) and second preset state (three-dimensional rendering disabled) based on real-time detection of user gaze direction and interaction permissions, optimizing power consumption while maintaining visual quality when needed
Solution Approach 2:
Different screens are assigned different rendering states independently based on their individual interaction permissions and user attention, allowing high-quality three-dimensional rendering only for screens that require user interaction while using lower-quality rendering for other screens
2Adaptability or versatility
If interaction functions are enabled for all screens, then user control and versatility are improved, but system complexity and processing overhead increase
Solution Approach 1:
Interaction permission status is independently configured for each screen, allowing the system to provide full interaction capabilities only where needed while simplifying or disabling interaction for other screens, thereby reducing overall system complexity
Solution Approach 2:
The system segments the control and state management of multiple screens, with each screen's interaction state managed independently based on its specific requirements, reducing the complexity of managing all screens uniformly

AI summary
A wearable device includes: a display; a sensor, memory storing instructions, and at least one processor comprising processing circuitry, wherein the instructions, when executed by the at least one processor individually or collectively, cause the wearable device to: identify, in a displaying area of the display, areas in which each of a plurality of screens is displayed; identify, based on a direction of a body part of a user wearing the wearable device, a first area among the areas corresponding to the direction, wherein the direction of the body part of the user is identified by data of the sensor; display, based on the identified first area, a first screen corresponding to the first area in a first preset state, and display at least one second screen that is different from the first screen in a second preset state that is different from the first preset state.
