Touch Input Intensity Detection for Dynamic Content Previews
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with touch-sensitive surfaces face inefficiencies in customizing touch input processing, requiring software updates and consuming excessive processing power, leading to battery drain and inefficient user interactions.
Innovation Solution
Implementing methods that detect the intensity of touch inputs on touch-sensitive surfaces, generating distinct 'force down' events and providing customizable processing, such as displaying previews or enlarging images based on input intensity, to streamline user interactions and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If predefined software operations are used for touch input processing, then device functionality is maintained, but customization is difficult and requires software updates
Solution Approach 1:
The system dynamically adjusts touch input processing behavior based on detected touch characteristics (duration, pressure, location) without requiring software updates. The processing logic adapts in real-time to different user interactions, allowing customization of operations such as image preview, enlargement, or navigation based on the specific touch pattern detected.
2Productivity
If conventional touch input processing is used, then basic functionality is provided, but processing efficiency is low and power consumption is high
Solution Approach 1:
The system performs only the necessary processing based on touch characteristics. For example, a light tap triggers a preview in a popup window without full page navigation, while a prolonged press triggers different behavior. This partial action approach avoids unnecessary processing steps and reduces power consumption while maintaining functionality.
3Adaptability or versatility
If multiple touch input interpretations are supported, then user interaction flexibility is improved, but processing complexity increases
Solution Approach 1:
The system segments touch input processing into distinct characteristic categories (duration, pressure, location) and evaluates each independently to determine the appropriate operation. This segmentation allows multiple interaction types to be supported through clear, separate decision criteria rather than complex integrated processing logic.

AI summary
An electronic device displays a content region including first content that contains an image; and, while displaying the first content, detects an input at a location that corresponds to the location of the image. In response, the electronic device, in accordance with a determination that the input includes an intensity above a respective threshold and that the image is associated with a link to second content that is different from the first content, displays a preview of the second content while maintaining display of at least a portion of the first content in the content region; and, in accordance with a determination that the input includes an intensity above the respective threshold and that the image is not associated with a link to additional content, displays an enlarged version of the image while maintaining display of at least a portion of the first content in the content region.
