Solution Overview

Problem

Existing technologies face challenges in efficiently transmitting and receiving tactile data of multiple channels with low delay, particularly as the number of vibrators increases, leading to longer transmission times and potential delays in tactile presentations.

Innovation Solution

The use of an estimator based on frequency analysis, pattern matching, or machine learning to divide tactile signals into base tactile signal groups, allowing for the conversion of tactile data into encoded data for efficient transmission and reception, while suppressing delays in tactile presentations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the number of vibrators is increased to provide a higher sense of reality, then the tactile presentation quality is improved, but the transmission time of tactile data increases

Engineering Contradiction:
Improvetactile presentation qualityVSAvoidtransmission time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The tactile signal is segmented into multiple base tactile signals belonging to different groups. Each group contains signals with similar characteristics, allowing the system to process and transmit only the essential information needed to reconstruct the tactile sensation, thereby reducing transmission time while maintaining quality

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the parameters of tactile signals by organizing them into groups based on their characteristics. By transforming the raw tactile data into grouped base signals with specific parameters, the system achieves efficient compression and transmission without losing the essential tactile information

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the number of channels for tactile data is increased to support more vibrators, then the tactile presentation capability is improved, but the transmission delay increases

Engineering Contradiction:
Improvetactile presentation capabilityVSAvoidtransmission delay
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Multiple tactile channels are merged into grouped base tactile signals. By combining signals with similar characteristics into single groups, the system reduces the total number of separate transmission channels needed while maintaining the ability to present complex tactile patterns across multiple physical vibrators

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The grouped base tactile signals serve multiple functions simultaneously. Each group can represent different tactile patterns and can be applied to multiple vibrators, making the transmission system more versatile and efficient at handling multi-channel tactile data

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

AI summary

The present disclosure relates to an information processing apparatus, an information processing method, and a program that can efficiently transmit a tactile signal for a plurality of tactile presentation units. A transmission apparatus breaks up a tactile signal included in content into a base tactile signal group, converts the base tactile signal group into encoded data including parameters defined for each of the broken up base tactile signals, and transmits the encoded data. A reception apparatus restores and combines the base tactile signals based on the parameters included in the encoded data to restore the tactile signal and makes a tactile presentation. The present disclosure can be applied to a content reproduction system including a tactile presentation apparatus.
