Sequential Text Block Display for Small Screen Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic visual displays face challenges in effectively presenting information on smaller screens, where larger text reduces information density and causes eyestrain, while smaller text increases difficulty in reading and requires frequent eye movement.
Innovation Solution
A method of displaying text in blocks of words, allowing users to select the block size and format, hiding less important text while keeping all text available, reducing eye movement and refocusing, and enabling easier reading by displaying important segments first.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If text size is increased for easier reading, then readability is improved, but information density per display area decreases
Solution Approach 1:
The text is divided into blocks of words that are displayed sequentially. Each block contains a specific number of words (e.g., 3-5 words) that are presented to the user at once, allowing larger text size while maintaining information density through controlled progression of content blocks.
Solution Approach 2:
The patent introduces a temporal dimension to text display by showing blocks of text sequentially over time rather than all at once. This transforms the traditional 2D spatial arrangement into a 3D space-time structure, allowing larger text blocks to be displayed while controlling overall information volume through temporal progression.
2Quantity of substance
If text size is decreased to increase information density, then information density is improved, but readability deteriorates and causes eyestrain
Solution Approach 1:
By segmenting text into manageable blocks of 3-5 words displayed at a time, the system allows smaller overall text size for high information density while each individual block remains large enough to be readable without excessive eyestrain, as users process one block at a time rather than scanning large amounts of small text.
Solution Approach 2:
The system displays only the necessary portion of text (partial action) in each block rather than requiring users to read entire paragraphs or pages at once. This partial display approach allows smaller text size while maintaining readability by limiting the cognitive and visual load to manageable chunks.
3Loss of information
If all text is displayed at once on small screens, then information completeness is improved, but eye movement and refocusing frequency increases
Solution Approach 1:
Text is segmented into blocks that are displayed sequentially, with each block containing a limited number of words. This segmentation reduces the total visual scanning distance and refocusing events compared to displaying all text at once, while maintaining information completeness through progressive disclosure of all text blocks over time.
Solution Approach 2:
The system prepares and organizes all text into blocks in advance (preliminary action), allowing users to navigate through predetermined blocks rather than scanning unstructured text. This preliminary organization reduces eye movement frequency by providing a structured progression path through the content.
4Stability of the object's composition
If text is displayed in traditional continuous format, then reading flow is maintained, but information must be reduced on smaller screens
Solution Approach 1:
By dividing text into sequential blocks of 3-5 words, the system maintains reading flow through continuous progression from one block to the next, while simultaneously controlling information volume displayed at any given moment. The block structure creates a natural reading rhythm that preserves flow without requiring reduction of total information content.

AI summary
A device includes a display screen and a processor. The processor is configured to convert a textual document into sequentially ordered portions of text and display at the same designated location on the display screen the portions of text one at a time in the sequential order for a user to read.
