Solution Overview

Problem

Conventional headphone systems render haptics only based on audio data, limiting the immersive experience by not incorporating non-audio events, such as visual or interactive data from virtual or augmented reality systems.

Innovation Solution

A haptically-enabled headphone system generates haptic signals from non-audio data, using internal or external sensors and data generators to produce haptic effects like vibrations, thermal, or electrostatic feedback, independent of audio data, enhancing the experience with events like collisions or environmental changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If haptics are rendered only based on audio data, then the system complexity remains low, but the immersive experience is limited

Engineering Contradiction:
Improveimmersive experienceVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The haptic output device is designed to respond to multiple types of input data (audio data and non-audio data) through a unified haptic signal generation process. The system can process both audio-derived signals and non-audio signals (such as visual or interactive data) using the same haptic rendering pipeline, making the device multi-functional without requiring separate hardware systems for different input types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

A haptic signal generator acts as an intermediary component that receives both audio data and non-audio data, processes them through consistent algorithms, and generates unified haptic signals. This mediator component enables the system to handle diverse input types without increasing overall system complexity, as the intermediary abstracts the complexity of multi-source processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If haptic signals are generated from non-audio data, then tactile feedback richness is improved, but data processing requirements increase

Engineering Contradiction:
Improvetactile feedback richnessVSAvoiddata processing requirements
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system selectively processes only the necessary portions of non-audio data that are relevant for haptic feedback generation. Rather than processing all available data streams in full detail, the haptic signal generator extracts and processes only the essential characteristics needed to create meaningful tactile feedback, reducing overall data processing requirements while maintaining feedback richness.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If multiple data sources are integrated for haptic rendering, then engagement in interactive environments is enhanced, but system adaptability requirements increase

Engineering Contradiction:
Improveengagement in interactive environmentsVSAvoidsystem adaptability requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The haptic rendering system is designed with universal processing capabilities that can handle multiple data sources (audio, visual, interactive) through a single unified framework. This multi-functional design allows the system to adapt to different interactive environments without requiring separate specialized systems for each data type, thereby enhancing engagement while controlling adaptability requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)
