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

VSEngineering 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

Engineering Contradiction:
Improveguiding functionVSAvoiddisplay information amount
Core Design Contradiction:
Ease of operationVSQuantity of substance

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improvedisplay qualityVSAvoidbrowsing region
Core Design Contradiction:
Illumination intensityVSArea of stationary object

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.

Inventive Principle:
Principle #23Feedback

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.
