Gaze-Based Wake-Free Control for Intelligent Speakers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wake-up-free function in intelligent speakers is not flexible enough to meet individual user requirements, as it is automatically deactivated after a fixed time, which does not accommodate varying user needs.
Innovation Solution
A control method and apparatus for an intelligent device that determines the state of a target function and detects user gazing operations to switch the function's state based on acquired information, allowing for flexible activation and deactivation according to user interaction, such as delaying deactivation when the user is actively using the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wake-up-free function is automatically deactivated after a fixed time, then the device can save energy and reduce unnecessary wake-ups, but the function becomes inflexible and cannot meet individual user requirements
Solution Approach 1:
The patent replaces traditional mechanical interaction (physical buttons, voice commands) with gaze-based control. The eye tracking system detects user gaze direction and duration to automatically control the wake-up-free function state, substituting mechanical input methods with optical sensing to improve flexibility without significantly increasing operational complexity
Solution Approach 2:
The system automatically determines whether to activate or deactivate the wake-up-free function based on detected gaze behavior, without requiring explicit user commands. The device self-adjusts its state by interpreting gaze duration and direction, making the system adaptive to user needs while maintaining simple interaction
2Ease of operation
If the wake-up-free function remains activated for extended periods, then user convenience is improved, but energy consumption increases and unnecessary wake-ups occur
Solution Approach 1:
The system uses periodic gaze detection to dynamically control the wake-up-free function state. Instead of continuous activation or fixed-time deactivation, the function state changes periodically based on detected gaze behavior patterns, allowing the system to balance user convenience with energy conservation through rhythmical on-off cycles triggered by user interaction
Solution Approach 2:
The eye tracking system provides real-time feedback about user attention to the device. When gaze is detected, the system feedback indicates the user wants the function active; when gaze is absent, feedback triggers deactivation. This feedback mechanism ensures the function remains active only when needed, improving convenience while preventing unnecessary energy consumption
3Ease of operation
If traditional interaction methods (voice commands, physical buttons) are used to control function state, then the interface is simple, but the user experience is less natural and intuitive
Solution Approach 1:
The patent replaces mechanical interaction interfaces (buttons, voice recognition) with an optical sensing system that tracks eye movements. This substitution enables more natural and intuitive control where simply looking at the device activates functions, eliminating the need for physical manipulation or verbal commands while managing detection complexity through specialized eye tracking hardware
