Adaptive Function Button Placement for Mobile Interface Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of mobile devices with multiple functions makes it difficult for users to find the appropriate function button, as numerous buttons are displayed on the screen, leading to user confusion and operational challenges due to varying usage frequencies, environments, and user characteristics.
Innovation Solution
An information processing device with a display portion, user recognition portion, button selection portion, and display control portion that recognizes users and moves function buttons to a specified position on the screen based on user attributes, usage history, and environmental factors, ensuring the most relevant button is easily accessible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If numerous function buttons are displayed on the display screen to provide multiple functions, then the device functionality is improved, but the ease of operation deteriorates as it becomes difficult for users to find the desired function button
Solution Approach 1:
The patent applies local quality by displaying different function buttons at different locations on the display screen based on user characteristics. The control unit determines the location of function buttons corresponding to functions suitable for each user's line of sight direction, thereby providing localized, personalized button placement that adapts to individual user needs while maintaining comprehensive device functionality.
2Adaptability or versatility
If function buttons are classified and displayed hierarchically to organize numerous functions, then the device functionality is improved, but the ease of operation deteriorates as it becomes difficult for users to locate the desired button
Solution Approach 1:
The patent applies preliminary action by pre-determining the locations of function buttons based on user characteristics before the user needs to operate them. The control unit determines appropriate button locations according to each user's line of sight direction in advance, so when users operate the device, the relevant buttons are already positioned in optimal locations, eliminating the need for users to search through hierarchical classifications.
3Adaptability or versatility
If many different types of function buttons are displayed at the same time to provide comprehensive functionality, then the device versatility is improved, but the ease of operation deteriorates as users cannot understand what button corresponds to what function
Solution Approach 1:
The patent applies local quality by displaying different sets of function buttons at different locations on the display screen based on user characteristics. The control unit determines the location of function buttons corresponding to functions suitable for each user's line of sight direction, thereby providing localized, personalized button placement that adapts to individual user needs while maintaining comprehensive device functionality.

AI summary
An information processing device is provided that includes a display portion, a user recognition portion, a button selection portion, and a display control portion. The display portion displays at least one function button that is related to a function that the information processing device is capable of performing. The user recognition portion recognizes a user who is operating the information processing device. The button selection portion selects, from among the at least one function button that is displayed on the display portion, at least one function button that corresponds to the user who has been recognized by the user recognition portion. The display control portion moves the function button that has been selected by the button selection portion from an initial position on a display screen of the display portion such that the function button is close to a specified position on the display screen.
