Solution Overview

Problem

Existing haptic output technologies fail to effectively enhance the sense of reality in virtual environments by not considering the spatial distance of haptic events from the user's perspective, leading to a disjointed experience.

Innovation Solution

An information processing system that includes a delay amount decision unit to calculate a delay for haptic outputs based on the event's position in a virtual space, incorporating both virtual distance and user proximity, ensuring synchronized haptic feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If haptic output is provided immediately upon event occurrence, then responsiveness is improved, but sense of distance from event is degraded

Engineering Contradiction:

Improveresponsiveness of haptic outputVSAvoidsense of distance from event

Core Design Contradiction:

SpeedVSLoss of information

Solution Approach 1:

The system pre-calculates the delay amount based on the event occurring position before the haptic output is generated. By determining the appropriate delay in advance, the system maintains immediate responsiveness to events while incorporating the spatial distance information, thus resolving the contradiction between quick response and distance perception.

2Loss of information

If haptic output delay is increased to enhance sense of distance, then immersion is improved, but responsiveness is degraded

Engineering Contradiction:

Improvesense of distance from eventVSAvoidresponsiveness of haptic output

Core Design Contradiction:

Loss of informationVSSpeed

Solution Approach 1:

The system dynamically adjusts the haptic output delay amount based on the event occurring position in the virtual space. Rather than using a fixed delay, the delay is calculated proportionally to the distance, allowing the system to optimize both responsiveness and sense of distance according to the specific spatial context of each event.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If fixed delay is applied to haptic output, then implementation simplicity is improved, but sense of spatial realism is degraded

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The system changes the delay parameter dynamically based on the event occurring position. Instead of using a constant delay value, the delay amount is adjusted as a variable parameter that corresponds to the spatial distance in the virtual space, thereby achieving spatial realism without excessive complexity.
