Single Gesture Adjusts Display Brightness and Mode Threshold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable devices require separate actions to adjust brightness and change modes, leading to inefficiencies and delayed visual feedback for users.
Innovation Solution
Implementing a single gesture, such as a two-finger swipe, to simultaneously adjust brightness and mode, allowing continuous motion to change settings with immediate visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate actions are used to adjust brightness and change mode, then each setting can be controlled independently, but the number of steps increases and user interaction becomes complex
Solution Approach 1:
The patent combines brightness adjustment and mode switching into a single gesture operation. When the user performs a swipe gesture, the system first adjusts brightness along the swipe direction, and when brightness reaches its maximum or minimum threshold, it automatically switches mode (day/night) and continues adjusting brightness from the new threshold. This merging of two separate functions into one gesture directly reduces operation complexity while maintaining ease of use.
Solution Approach 2:
The swipe gesture is designed to perform multiple functions: it can adjust brightness levels and switch between day and night modes. This multi-functional gesture eliminates the need for separate operations for each setting, directly addressing the contradiction by reducing the number of steps required while maintaining independent control over both parameters through a single universal action.
2Productivity
If multiple separate steps are required to change mode, then precise control is maintained, but the time required to implement changes increases
Solution Approach 1:
The patent implements continuous adjustment of brightness throughout the entire swipe gesture duration. Unlike traditional methods where settings are changed in discrete steps through menus, the brightness adjustment occurs continuously as the user swipes, and mode switching happens automatically when thresholds are reached during the same continuous action. This eliminates idle time between operations and directly reduces the time to implement changes.
Solution Approach 2:
The system prepares for mode switching by continuously monitoring brightness levels during the swipe gesture. When brightness reaches a threshold value, the mode switch is automatically triggered without requiring additional user actions. This preliminary preparation and automatic triggering mechanism eliminates the time loss associated with manual mode switching steps.
3Ease of operation
If conventional separate controls are used, then each setting can be adjusted independently, but visual feedback is delayed
Solution Approach 1:
The patent implements immediate visual feedback by changing the displayed content's brightness in real-time as the user performs the swipe gesture. The brightness adjustment is applied continuously during the gesture, and mode switching is reflected immediately when thresholds are reached. This real-time feedback mechanism eliminates the delay inherent in traditional menu-based systems where users must navigate through multiple screens to see the effect of their settings.
Data Source
AI summary
Content is displayed on a touchscreen display of a computing system such as an electronic book reader. The content is displayed according to a setting for a first attribute (e.g., level of brightness) and a setting for a second attribute (e.g., day mode or night mode). In response to sensing a motion proximate to the touchscreen, the setting for the first attribute is changed to a different value. In response to a value for the setting for the first attribute crossing a threshold value (e.g., while the motion is being performed), the setting for the second attribute is changed.
