Particle Effect Display for Touch Input Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices lack visual feedback when users perform input operations on their touch screens, such as switching between pages or applications, which can lead to a less engaging and less interactive user experience.
Innovation Solution
A method and electronic device that generate particle effects on the screen based on input parameters like duration, pressure intensity, gesture type, and input tool, creating moving particles with varying sizes, shapes, and colors to provide visual feedback around the input area, enhancing user interaction and engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no effect is provided in response to user input, then the device maintains simplicity and avoids unnecessary processing, but the user experience becomes less engaging and interactive
Solution Approach 1:
The system changes parameters such as particle size, particle count, particle shape, and duration based on input parameters (duration, pressure intensity, gesture type, input tool) to create varied particle effects that enhance user engagement without requiring complex hardware modifications
Solution Approach 2:
The system creates visual copies in the form of particle effects that mirror and respond to user inputs, providing feedback that enhances interaction without adding physical components to the device
2Loss of information
If particle effects with varying sizes, shapes, and colors are generated based on multiple input parameters, then visual feedback and user engagement are enhanced, but the processing complexity and computational requirements increase
Solution Approach 1:
The system applies different particle properties (size, shape, color, duration) to different regions and contexts based on local input characteristics, such as creating larger particles for pressure inputs and colored particles for specific gesture types, providing tailored visual feedback without uniform complexity throughout

AI summary
Methods and electronic devices for displaying a particle effect are described. One method includes receiving an input on an area of a display screen, the area having a color. A main particle color is set based on the color, and then a secondary particle color is set based on the main particle color. A plurality of moving particles are displayed, the moving particles moving around the input area, and each of the plurality of moving particles has a color on a spectrum from the main particle color to the secondary particle color.
