Mobile Device RSVP Text Display Dynamic Font Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile wireless communications devices face challenges in displaying content efficiently due to limited display area and user accessibility issues, particularly for users with impaired vision, as existing adaptations of Rapid Serial Visual Presentation (RSVP) do not fully leverage the features of modern cellular phones to enhance reading speed.
Innovation Solution
A mobile wireless communications device that dynamically adjusts font size and style based on the physical orientation and display area, using an orientation sensor to select the largest font size for the longest fragment, and implements RSVP to display textual content along a diagonal, allowing for increased reading speed and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional scrolling display is used on mobile devices, then all content can be displayed, but reading time increases and user convenience deteriorates
Solution Approach 1:
The patent segments textual content into individual words or phrases and displays them sequentially one at a time in a fixed location on the display, eliminating the need for scrolling and enabling faster reading through Rapid Serial Visual Presentation
Solution Approach 2:
The patent employs periodic display of text fragments at controlled intervals, presenting each word or phrase for a specific duration before transitioning to the next, which optimizes reading speed while maintaining comprehension
2Area of stationary object
If smaller text is displayed to fit limited screen area, then more content can be shown, but readability for users with impaired vision deteriorates
Solution Approach 1:
The patent transitions from horizontal scrolling to vertical temporal sequencing, displaying text in the time dimension rather than requiring horizontal space, allowing large font sizes to be displayed without sacrificing content volume
Solution Approach 2:
The patent dynamically adjusts font size, display duration, and presentation rate based on user preferences, visual capabilities, and content characteristics, optimizing both readability and information density
3Productivity
If RSVP is implemented on mobile devices, then reading speed increases, but display flexibility and content presentation options are reduced
Solution Approach 1:
The patent implements dynamic adjustment of RSVP parameters including display rate, font size, and text fragmentation level based on user feedback, device orientation, and content type, maintaining versatility while achieving rapid reading
Solution Approach 2:
The patent changes multiple display parameters simultaneously including presentation speed, font characteristics, and text segmentation density to optimize reading efficiency while adapting to different content types and user needs

AI summary
A mobile wireless communications device (12) includes a wireless transceiver (14), a display (13) having an available display area and a memory (15). A processor (17) cooperates with the wireless transceiver for downloading textual content having a plurality of words and storing the textual content in the memory. The processor also cooperating with the memory for generating successive fragments of the textual content, each fragment having at least one word. The successive fragments are searched to locate a longest fragment. A selected font in which the longest fragment can be displayed on the display area of the display is determined. Rapid serial visual presentation (RSVP) is used for displaying on the display area of the display the successive fragments of the textual content in the selected font.
