Tactile Vibration Guidance for Smartphone Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for guiding users through large-area content on smartphones are inadequate, as they either increase display information, making it cumbersome, or narrow the browsing region, making it difficult to determine the direction for reading or browsing without visual cues.
Innovation Solution
A personal digital assistant uses tactile perception by employing vibration elements at different locations on the casing to guide users intuitively to the next browsing direction without increasing display information or narrowing the browsing region, utilizing vibration strength ratios to indicate the direction of the guiding target location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If text information is provided to guide the user, then the guiding function is achieved, but the display information amount increases making the screen cumbersome
Solution Approach 1:
The patent replaces visual text information (mechanical display system) with tactile vibration feedback (mechanical vibration system). Vibration elements are activated at different locations and with different strengths to indicate browsing direction, substituting the need for text-based guidance while maintaining the guiding function without increasing visual information load.
Solution Approach 2:
The patent introduces vibration elements as an intermediary between the content and the user. Instead of directly displaying text guidance on the screen, the system uses tactile vibrations transmitted through the casing to convey directional information, acting as a mediator that transfers guidance information through a different sensory channel.
2Illumination intensity
If the content is enlarged to fit the display, then the display quality improves, but the browsing region is narrowed making it difficult to determine reading direction
Solution Approach 1:
The patent implements a feedback mechanism where vibration elements provide real-time directional guidance based on the user's current browsing position. The system detects the user's location within the content and activates appropriate vibration patterns to indicate the next browsing direction, creating a closed-loop feedback system that guides users through enlarged content without losing orientation.
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
This solution allows users to navigate large-area content effectively by providing intuitive tactile guidance, ensuring the user can browse in the correct direction without visual clutter or reduced browsing regions, enhancing usability for various types of content like newspapers and maps.

AI summary
An information processing apparatus that determines a direction to browsed next as a guiding direction with a location of content displayed by a display of the information processing apparatus as a reference location; determines a perceptual strength of each of a plurality of active elements disposed in different locations on or within a casing of the information processing apparatus based on the guiding direction; and controls each of the plurality of active elements based on the perceptual strengths.
