Pressure-Sensitive Input for Content Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display methods for retrieving content items from large datasets are inefficient, requiring multiple steps and potentially leading to missed content items due to incomplete viewing of data, especially when switching between date-based categories and content displays.
Innovation Solution
An image display apparatus and method utilizing a pressure-sensitive input device to generate distinct operation signals based on pressing force, allowing sequential switching between content and category displays with transient screens providing overviews, enabling faster and more intuitive retrieval of desired content items by distinguishing between weak and strong pressing forces for navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple operational steps are required for switching between lists (as in Patent Document 2), then erroneous selections can be prevented, but operability deteriorates due to the complexity of operations
Solution Approach 1:
The patent changes the parameter of pressing force magnitude to differentiate between selection operations. By detecting whether the pressing force exceeds a threshold, the system distinguishes between tentative selection (weak press) and confirmation (strong press), eliminating the need for multiple sequential steps while maintaining reliable error prevention
Solution Approach 2:
The system dynamically adjusts its response based on the magnitude of the pressing force applied. Instead of a static binary state (pressed/not pressed), the system continuously monitors force magnitude and transitions between different operational modes (browsing vs. selection) based on this dynamic parameter, enabling intuitive one-step operations
2Ease of operation
If the list is switched without displaying all content items, then the operation can be simplified, but content items may be missed
Solution Approach 1:
Before switching from the first list to the second list, the patent performs a preliminary action of displaying a transient screen showing all content items that will be displayed in the second list. This allows users to review all available content before the switch, preventing missed items while maintaining simple one-step navigation
3Speed
If a transient screen is not displayed during list switching, then the transition is faster, but users cannot view all content items in the category
Solution Approach 1:
The patent uses a transient screen that displays all content items briefly during the transition moment. This transient display skips the need for separate viewing steps while still providing the overview, allowing users to quickly scan all content before the final list switch occurs, thus maintaining speed while preventing information loss
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances operability by allowing quick and accurate retrieval of content items through fewer operational steps, preventing missed items by displaying all content within a category during transitions and providing an overview of unviewed content during category changes.
Implementation Method 1
an operating section which generates a first operation signal according to a first operation performed with a weak pressing force and a second operation signal according to a second operation performed with a pressing force stronger than that of the first operation

AI summary
An image display apparatus includes: a storage section for storing a plurality of content items sorted using categories of a higher level; a display section for displaying either of the content items or the categories; an operating section generating a first operation signal according to a first operation performed with a weak pressing force and a second operation signal according to a second operation performed with a pressing force stronger than that of the first operation; and a control section receiving the input of the first operation signal and the second operation signal and controlling a display image displayed on the display section.
