Haptic Control Signal Generation for Synchronized Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for presenting haptic stimuli, such as vibrations, lack a comprehensive method for generating and reproducing control data in synchronization with content reproduction, particularly in environments like movie theaters or theme parks, leading to an incomplete user experience.
Innovation Solution
An information processing system that includes a control unit generating haptic control signals based on position and type information for haptic stimulus units, and a script associating time information with these signals to synchronize the haptic presentation with reproduction content, allowing for the creation and reproduction of haptic control data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a haptic presentation device is used to present haptic stimuli to users, then the realistic sensation is amplified, but the system for generating and reproducing control data in synchronization with reproduction content is insufficient
Solution Approach 1:
The patent applies preliminary action by generating haptic control signals and creating synchronization scripts before the actual reproduction content is played. The control unit generates control signals based on position information, haptic stimulus type information, and device arrangement data, then associates these signals with time information from the reproduction content in advance. This pre-synchronization approach ensures reliable timing without requiring complex real-time processing during content playback.
2Manufacturing precision
If control signals are generated for each haptic stimulus unit based on position and type information, then the haptic presentation accuracy is improved, but the processing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the haptic control system into distinct functional components: position information processing, haptic stimulus type identification, device arrangement data storage, and control signal generation for each individual haptic stimulus unit. Each haptic stimulus unit receives dedicated control signals tailored to its specific position and function, enabling precise control while organizing the complexity into manageable modular segments.
3Reliability
If time information is associated with haptic control signals in a script, then the synchronization with reproduction content is improved, but the data processing burden increases
Solution Approach 1:
The patent applies copying by creating a script that contains copied or referenced time information from the reproduction content and associates it with pre-generated haptic control signals. Instead of processing complex real-time synchronization data, the system uses a script format that stores time stamps and control signal references, allowing efficient retrieval and execution during content playback without heavy processing burdens.

AI summary
An information processor (10m) includes a control unit (104). On a basis of position information indicating a perceptual position that causes a haptic stimulus to be perceived in a haptic presentation device (2) and on a basis of haptic stimulus type information specifying a type of the haptic stimulus, and in accordance with an arrangement of one or more haptic stimulus units provided in the haptic presentation device (2), the control unit (104) generates a haptic control signal to each of the haptic stimulus units for presentation of the haptic stimulus of the type specified at the perceptual position, and a script in which time information on a reproduction content and one or more of the generated haptic control signals are associated with each other.
