Touch Screen Selection Indicator for Small Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screens with small sizes and high-resolution displays face challenges in precise selection due to parallax errors and the difficulty in distinguishing between closely packed digital images, leading to accidental selections and user inconvenience.
Innovation Solution
The implementation of a system that displays a floating icon or alters digital image characteristics to indicate selectability, allowing users to select objects without zooming in, thereby reducing errors and maintaining the visibility of all information on the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the touch screen size is reduced to fit small devices, then device portability is improved, but selection precision deteriorates
Solution Approach 1:
An indicator is introduced as an intermediary element that mediates between the user's touch input and the target digital image. The indicator visually highlights the selectable object, allowing users to accurately identify and select images on small screens without needing to physically locate and precisely touch the small target area.
2Loss of information
If multiple digital images are displayed simultaneously, then information visibility is improved, but selection difficulty increases
Solution Approach 1:
Instead of uniformly displaying all digital images with equal visual weight, the indicator applies local quality enhancement by highlighting only the currently selectable image. This allows multiple images to remain visible for information purposes while the highlighted image stands out for selection purposes, reducing selection difficulty without sacrificing information visibility.
3Measurement precision
If zooming is used to improve selection precision, then selection accuracy is improved, but screen real estate is reduced
Solution Approach 1:
The selection indication function is extracted from the digital image itself and represented by a separate indicator element. This allows the indicator to be overlaid on or associated with the target image without requiring the image to be enlarged, maintaining full screen real estate availability while providing visual selection guidance.

AI summary
An approach to selecting an object represented on a touch screen display includes displaying a plurality of independent digital images on the touch screen display, indicating one of the plurality of independent digital images is selectable, detecting if interaction with the touch screen display is made while one of the plurality of independent digital images is indicated as selectable, and if interaction with the touch screen display is not made while the one of the plurality of independent digital images is indicated as selectable, indicating a subsequent digital image is selectable.
