Solution Overview

Problem

Conventional haptic presentation devices fail to provide a realistic haptic stimulus to users by not processing haptic stimulus values based on sensing information, resulting in a lack of dynamic and immersive experiences.

Innovation Solution

An information processing device that acquires sensing information regarding a user and generates second haptic information from first haptic information unique to a haptic presentation object, allowing for the presentation of a more realistic haptic stimulus by processing the haptic stimulus values based on user interactions and environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If haptic stimulus values are presented directly without processing based on sensing information, then the system operation is simple, but the haptic stimulus lacks realism and dynamic response

Engineering Contradiction:

Improverealism of haptic stimulusVSAvoidcomplexity of haptic information processing

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system pre-processes haptic information by creating a relationship between sensing information and haptic stimulus values before actual haptic presentation occurs. This preliminary processing enables the haptic device to dynamically adjust stimulus values based on user interactions and environmental conditions, improving realism without adding complex real-time processing during haptic delivery

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where sensing information from user interactions and environmental sensors continuously influences the haptic stimulus values. The haptic information processing unit adjusts stimulus values based on this feedback, creating a dynamic and realistic haptic experience that responds to user actions and environmental changes

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If haptic stimulus values are dynamically adjusted based on sensing information, then the haptic stimulus becomes more realistic and immersive, but the information processing complexity increases

Engineering Contradiction:

Improvedynamic response of haptic stimulusVSAvoidcomplexity of haptic information processing

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The haptic information processing unit is designed to handle multiple types of sensing information (user interactions, environmental conditions) and adjust haptic stimulus values accordingly. This multi-functional approach allows the system to adapt to various scenarios and user needs while using a single integrated processing unit, reducing overall system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system pre-establishes the framework for dynamic haptic adjustment by creating the processing unit and defining the relationships between different sensing information types and haptic stimulus values. This preliminary setup enables versatile dynamic response without requiring complex real-time decision-making algorithms during actual haptic presentation

Inventive Principle:

Principle #10Preliminary action
