Dynamic Object Image Display for Touch Panel Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
On touch panels with smaller screen sizes, the display of multiple object images is inefficient due to the need for frequent scrolling, as increasing the display area of each object image reduces the number of images visible on screen, making it less user-friendly.
Innovation Solution
An image display apparatus with a coordinate detector and controller that dynamically adjusts the number of object images displayed within a single screen area, allowing for continuous arrangement and swapping of images based on user input operations, thereby optimizing visibility and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display area of each object image is increased, then the tapping operation accuracy is improved, but the number of object images displayable within a single screen decreases
Solution Approach 1:
The patent implements dynamic adjustment of the number of displayed object images based on user interaction. Initially, N object images are displayed, and upon detecting a pressing operation, the system increases the display to K object images (where K > N). This dynamic reconfiguration allows the display to adapt between showing fewer images with larger areas and showing more images with smaller areas, resolving the contradiction between tapping accuracy and information density.
Solution Approach 2:
The system changes the parameter of the number of displayed object images from N to K in response to user input. This parameter change allows the display to transition between different states: a initial state with N images for accurate tapping, and an expanded state with K images for comprehensive viewing. The parameter is adjusted based on the detected pressing operation, enabling the system to optimize between the two conflicting requirements.
2Measurement precision
If the number of object images displayable within a single screen decreases, then the tapping operation accuracy is improved, but the scrolling frequency increases
Solution Approach 1:
The system dynamically adjusts the number of displayed images between N and K based on user interaction patterns. When a pressing operation is detected, the display expands to show K images, reducing the need for frequent scrolling. This dynamic adaptation allows the system to maintain high tapping accuracy while minimizing scrolling frequency by showing more images when the user is actively searching through the list.
3Productivity
If more object images are displayed within a single screen, then the scrolling frequency is reduced, but the tapping operation accuracy decreases
Solution Approach 1:
The patent employs dynamic reconfiguration of the display based on user input. The system starts with N object images displayed for accurate tapping, and upon detecting a pressing operation, expands to display K object images (K > N) to reduce scrolling frequency. This dynamic adjustment ensures that the system optimizes between tapping accuracy and scrolling frequency based on the user's current needs.
Solution Approach 2:
The system changes the display parameter from showing N images to showing K images in response to user interaction. This parameter change allows the display to adapt to different user states: showing fewer images when precise tapping is needed, and showing more images when the user is browsing or searching, thereby reducing scrolling frequency without permanently compromising tapping accuracy.

AI summary
An image display apparatus includes a controller configured to display N object images within a first display area of a display, the N object images are included in first to M-th object images, in response to a first operation input via the display while the N object images are displayed, determining K object images including the N object images, display the K object images within the first display area, in response to a second operation input via the display while the K object images are displayed, change the K object images to another set of K object images, display the changed K object images within the first display area, in response to a third operation input via the display while the changed K object images are displayed, extracting N object images from among the changed K object images, and display the extracted N object images within the first display area.
