Alternate Gesture Mode for Touchscreen Inadvertent Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic personal display devices, such as e-readers and tablets, often face issues with inadvertent triggering of input commands due to their touch-sensitive screens, especially when used by young children, leading to undesirable page transitions during reading.
Innovation Solution
Implementing an alternate gesture mode that requires a higher degree of human motor skills coordination by disabling touch functionality on the main display screen and re-enabling it only on a smaller, spatially exclusive portion, where a more complex predefined gesture must be performed for page transitions, reducing the likelihood of accidental input commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire display screen is made touch-sensitive for easy navigation, then ease of operation is improved, but inadvertent triggering of input commands increases
Solution Approach 1:
The display screen is segmented into multiple touch-sensitive regions with different functions. The first region (e.g., left side) triggers first-page transitions while the second region (e.g., right side) triggers second-page transitions. This segmentation allows easy navigation through distinct zones while reducing inadvertent triggering by providing spatially separated control areas.
Solution Approach 2:
Different portions of the display screen are assigned different touch sensitivity characteristics and functions. The first portion responds to gestures for first-page transitions with specific sensitivity parameters, while the second portion has different sensitivity parameters for second-page transitions. This local differentiation enables easy operation in each zone while preventing accidental activation in wrong zones.
2Ease of operation
If gesture recognition sensitivity is increased for responsive navigation, then ease of operation is improved, but false gesture detection increases
Solution Approach 1:
Gesture detection is segmented by spatial region on the display screen. Each region (first and second portions) has its own gesture recognition parameters and sensitivity thresholds. This allows responsive navigation within each zone while reducing false detection by confining gesture patterns to their intended regions.
Solution Approach 2:
Different sensitivity parameters, gesture thresholds, and recognition criteria are applied to different portions of the display screen. The first portion uses parameters optimized for first-page transition gestures, while the second portion uses parameters for second-page transition gestures. This parameter differentiation enables responsive navigation while minimizing false gesture detection.

AI summary
A method and system for providing an alternate gesture interface. A computing device, such as an electronic personal display or e-reading device, includes a memory and a display screen having touch functionality. The memory stores instructions configured to enact a page transition operation for digital content rendered on the display screen upon receipt of a first gesture input action performed at a first portion of the display screen. The method comprises receiving a gesture-mode switch request; in response to the gesture-mode switch request, disabling the touch functionality of the display screen; activating the touch functionality in only a second portion of the display screen, the second portion being at least partly spatially exclusive of the first portion of the display screen; and enacting the page transition operation only when a predefined second gesture input action is received at the second portion of the display screen.
