Gaze-Based Notification Adaptation for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User devices, such as mobile phones, often provide redundant notifications when the user's gaze is directed towards the screen, wasting power and resources by outputting both visual and non-visual alerts simultaneously.
Innovation Solution
Implementing a gaze detection system that determines the user's gaze direction using camera input, allowing the device to selectively output notifications as either visual, audio, or haptic based on whether the user is facing the screen, thereby disabling redundant forms of notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user device outputs both visual and non-visual notifications simultaneously, then the notification delivery is comprehensive, but the power consumption increases and resources are wasted
Solution Approach 1:
The notification system dynamically adjusts the type of notification output based on real-time detection of user gaze direction. When the user is detected to be looking at the display, visual notifications are output; when looking away, non-visual notifications (audio or haptic) are output. This dynamic adaptation eliminates redundant notifications and reduces power consumption while maintaining comprehensive notification delivery.
Solution Approach 2:
The system changes the parameter of notification modality (visual vs. non-visual) based on the detected state of user gaze. By monitoring gaze direction and switching between different notification types, the system optimizes power consumption without compromising notification effectiveness.
2Reliability
If the user device outputs both visual and non-visual notifications simultaneously, then the notification delivery is comprehensive, but the resources are wasted
Solution Approach 1:
The system extracts and removes redundant notification outputs by detecting user gaze direction. When the user is looking at the display, non-visual notifications are eliminated; when looking away, visual notifications are suppressed. This selective removal of unnecessary notifications reduces resource waste while maintaining effective notification delivery.
Solution Approach 2:
The notification system dynamically determines which notification modality to use based on real-time gaze detection, eliminating redundant outputs and optimizing resource utilization.
3Productivity
If the gaze detection system is implemented, then the notification efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent leverages the existing front-facing camera, originally designed for other purposes (such as selfies or video calls), and repurposes it for gaze detection. This multi-functional use of the camera minimizes additional hardware requirements and reduces overall system complexity while enabling efficient gaze-based notification control.
Solution Approach 2:
The system uses the device's own existing resources (camera, processor, display) to implement gaze detection and adaptive notification delivery, rather than requiring entirely new specialized components. This self-service approach reduces complexity by utilizing already-present hardware.
Data Source
AI summary
A device may determine whether a user is facing a display screen associated with the device; and present feedback to the user. When presenting the feedback, the device may present visual information, that is based on the feedback, when determining that the user is facing the display screen associated with the device, and present audio information, that is based on the feedback, when determining that the user is not facing the display screen associated with the device. At least a portion of the audio information might not be presented when the visual information is presented when the user is facing the display screen associated with the device.
