Image Display Device Automatic Page Switching Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices require repetitive user input for switching between pages, which can be cumbersome and inconvenient, especially when viewing large amounts of content, and do not provide efficient navigation or feedback on the current position within the content.
Innovation Solution
An image display device with a controller that detects user input and automatically switches images at a stored speed after a predetermined number of flick operations, allowing continuous viewing while providing optional pop-up indications for demarcation points within the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic image switching is implemented, then user convenience is improved and repetitive input is reduced, but device complexity increases due to additional detection and control sections
Solution Approach 1:
The detection section serves multiple functions: it detects both the user's flick operation to determine switching direction and counts the number of flicks to determine when to enable automatic switching. This multi-functionality reduces the need for separate components, thereby improving ease of operation while minimizing the increase in device complexity.
Solution Approach 2:
The system performs automatic image switching without requiring continuous user input after the initial flick operations. The image display controller automatically switches images based on the stored switching direction and speed, reducing repetitive user input and improving ease of operation with minimal additional complexity.
2Productivity
If automatic switching is enabled after predetermined flicks, then productivity is improved through faster content navigation, but ease of operation deteriorates due to loss of manual control
Solution Approach 1:
The system dynamically transitions from manual control to automatic switching based on the number of flick operations performed. Initially, the user has full manual control, but after a predetermined number of flicks, the system automatically switches images. This dynamic adjustment optimizes productivity for continuous viewing while preserving manual control when needed.
Solution Approach 2:
The system periodically checks the number of flick operations and transitions between manual and automatic modes. This periodic evaluation allows the system to maintain manual control for initial navigation while enabling automatic switching for efficient content browsing, balancing productivity and ease of operation.
3Productivity
If image switching speed is increased, then productivity is improved through faster page turnover, but measurement precision deteriorates as users cannot accurately perceive content position
Solution Approach 1:
The system provides visual feedback by displaying the current page number or position indicator during automatic switching. This feedback mechanism allows users to accurately perceive content position even at higher switching speeds, maintaining measurement precision while improving productivity through faster page turnover.

AI summary
An image display device includes: a display that displays an image which represents a first part of information content and that switches the image to represent a second part of the information content; a detection section that detects a contacting object which contacts the display; an image switch determination section that determines whether or not to switch the image displayed on the display in accordance with operation of the contacting object detected by the detection section; a speed storage section that stores a speed at which the image is switched in the case where the image switch determination section determines to switch the image; and an image display controller that controls the display to continuously switch the image to represent subsequent part of the information content at the speed stored in the speed storage section when the image is continuously switched a predetermined number of times or more.
