Haptic Signal Processing for Merging Sensory Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing haptic presentation technologies fail to consistently provide appropriate sensory effects when multiple haptic presentations are combined, as they do not account for human sensory characteristics, leading to unintended sensory experiences.
Innovation Solution
An information processing apparatus and method that generates a haptic signal by considering sensory characteristic data to merge the sensory effects of multiple haptic presentations occurring simultaneously, ensuring a combined sensory effect that aligns with the intended perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple haptic presentations are combined without considering human sensory characteristics, then the device complexity is reduced, but the sensory effect accuracy deteriorates
Solution Approach 1:
The patent applies parameter changes by adjusting haptic signal parameters (amplitude, frequency, duration) based on sensory characteristic data. The signal processing section modifies presentation parameters dynamically according to the type and timing of multiple haptic presentations, transforming raw sensor data into optimized haptic signals that account for human sensory characteristics and achieve accurate combined sensory effects.
2Reliability
If haptic signals are generated without considering sensory characteristic data, then the ease of operation is improved, but the reliability of sensory effects deteriorates
Solution Approach 1:
The patent implements feedback by using sensory characteristic data as input to the signal processing section, which generates haptic signals based on feedback from the sensor section. The system continuously monitors and adjusts haptic presentations according to detected sensory characteristics, ensuring consistent and reliable sensory effects while maintaining automated operation.
3Measurement precision
If overlapping haptic presentations are handled simply, then the productivity is improved, but the measurement precision of sensory effects deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-processing sensory characteristic data and preparing haptic signal parameters before actual presentations occur. The signal processing section anticipates overlapping presentations and pre-calculates appropriate signal combinations, enabling accurate measurement of combined sensory effects while maintaining high processing speed through preparedness.
Data Source
AI summary
There is provided an information processing apparatus, an information processing method, and a program for performing more appropriate haptic presentations. The information processing apparatus includes a signal processing section configured such that in a case where the presentation timing of a first presentation with haptic sensation based on first data overlaps with the presentation timing of a second presentation with either haptic sensation or a sound based on second data, the signal processing section generates a haptic signal for controlling a haptic presentation device performing at least the first presentation based on sensory characteristic data regarding the haptic sensation and on the first data in such a manner that a combined sensory effect on a user receiving both the first presentation and the second presentation becomes an effect merging a first sensory effect of the first presentation with a second sensory effect of the second presentation.
