Touch Screen Icon Orientation Detection and Speech Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices face inconvenience when trying to find specific application icons on a cluttered screen, especially when visual recognition is impaired, as they must search the entire screen to locate the correct icon, and there is no clear indication of the direction of other icons relative to the intended one.
Innovation Solution
An electronic device with a processor, touch screen, and memory that detects touch inputs to identify the orientation for rearranging selectable objects, outputs information about the objects, and rearranges them based on the detected orientation, allowing users to easily find desired applications through a prioritized and organized layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If icons are displayed densely on the screen to accommodate multiple applications, then the screen utilization is improved, but the ease of finding a specific icon deteriorates
Solution Approach 1:
The patent introduces a speech output intermediary that mediates between the user and the icons. When visual recognition is impaired, the system outputs speech information about icons in a specific search order, allowing users to locate desired icons through auditory feedback rather than visual scanning, thus resolving the contradiction between dense display and ease of finding icons
Solution Approach 2:
The patent changes the parameter of information presentation from visual-only to auditory-speech output. By outputting speech information about icon identities in a predetermined search order, the system enables users with impaired visual recognition to efficiently locate icons without requiring visual differentiation among densely packed icons
2Device complexity
If the screen displays all icons in a fixed arrangement, then the device complexity is reduced, but the adaptability to user needs deteriorates
Solution Approach 1:
The patent implements dynamic adaptability by allowing the search order to be flexibly determined based on user input. When a user provides a keyword, the system dynamically adjusts the search order to prioritize icons matching the keyword, transforming a static fixed arrangement into a dynamic adaptive system that responds to user needs without increasing device complexity
3Ease of operation
If a user with impaired visual recognition touches a position on the screen, then the user attempts to locate an icon, but the user cannot determine the direction to search without visual feedback
Solution Approach 1:
The speech output system acts as an intermediary that compensates for lost spatial visual information. When a user touches a position, the system outputs speech information about icons in a search order radiating from that position, providing directional spatial information audibly so users can understand the arrangement and locate icons without visual feedback

AI summary
An electronic device and method are disclosed herein. The electronic device includes a processor, a touch screen and a memory including instructions executable by the processor to execute the method, including: when detecting a first touch input to the touch screen, identifying an orientation for arranging a plurality of selectable objects, rearrange one or more objects from among the plurality of selectable objects according to the identified orientation relative to a location on the touch screen where the first touch input is detected, and outputting information associated with a particular object from among the rearranged one or more objects corresponding to detection of a second touch input.
