Touchscreen Wake-Up Gestures for Low-Power Display Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with touch-sensitive displays face challenges in conserving power while maintaining user-friendly navigation and functionality, particularly when transitioning between power modes.
Innovation Solution
Implementing a method that switches the device to a low power mode based on trigger conditions and uses designated wake-up gestures, such as meta-navigation gestures, to transition back to full power mode, utilizing the non-display area and buffer regions of the touch-sensitive overlay to detect these gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device continuously monitors touch inputs to maintain responsiveness, then user interaction responsiveness is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts its operational state between full power mode and low power mode based on detected gestures. During low power mode, the device enters a state where only specific wake-up gestures are detected, reducing overall monitoring activity while maintaining the ability to respond to important user inputs.
Solution Approach 2:
The patent introduces an intermediary gesture recognition layer that filters touch inputs before they reach the full system. The system first determines whether a touch is a wake-up gesture, and only then activates full system responsiveness, thereby reducing unnecessary processing and power consumption.
2Use of energy by moving object
If the device enters low power mode to conserve battery, then power consumption is reduced, but device responsiveness and accessibility deteriorate
Solution Approach 1:
The system performs preliminary gesture classification to identify wake-up gestures before fully activating the device. By预先 determining the nature of the touch input, the system can efficiently transition from low power mode without requiring full system activation, thus conserving power while maintaining responsiveness.
Solution Approach 2:
The patent applies different monitoring qualities to different gesture types. Wake-up gestures receive high-priority, localized attention with simplified detection logic, while other gestures are either ignored or processed with full system activation. This selective approach maintains essential responsiveness while reducing overall power consumption.
3Ease of operation
If the device uses the entire touch-sensitive display area for interaction, then ease of use is improved, but accidental inputs increase
Solution Approach 1:
The patent designates specific local regions of the touch-sensitive display as wake-up gesture zones, typically along the edges or borders. By confining wake-up gesture detection to these specific areas rather than the entire display, the system maintains ease of access while significantly reducing the likelihood of accidental wake-up inputs from central display interactions.
Solution Approach 2:
The touch-sensitive display is segmented into different functional zones: wake-up gesture zones (typically peripheral areas) and regular interaction zones (central display area). This segmentation allows the system to distinguish between intentional wake-up gestures and regular interactions, reducing accidental inputs while maintaining overall ease of use.
