Haptics Control Signal Modulation for Tactile Perception Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing haptic feedback technologies struggle to provide a consistent and realistic tactile experience due to individual variations in tactile sensitivity and situational changes among users, leading to differences in how users perceive haptics, even when using the same device in a predetermined mode.
Innovation Solution
An information processing device and method that acquires context information about the user's state or environment and modulates control signals for a haptics unit to adjust tactile feedback, accounting for user-specific and environmental factors such as age, emotional state, activity level, and environmental conditions to standardize the tactile experience.

Engineering Contradiction Analysis
1Ease of operation
If haptics are presented using a predetermined mode, then the device operation is simple, but the way of feeling haptics varies between users and situations
Solution Approach 1:
The haptic control signal is dynamically adjusted based on context information about the user's state and situation. The system transitions from a static predetermined mode to a dynamic adaptive mode where haptic parameters change in response to detected user conditions, resolving the contradiction between operational simplicity and perception consistency.
Solution Approach 2:
The system changes haptic parameters (such as vibration frequency, amplitude, or pattern) based on acquired context information about the user's state. By modifying these parameters adaptively, the system maintains consistent haptic perception across different users and situations while keeping the overall system operation simple through automated adjustment.
2Reliability
If haptic parameters are adjusted for each user and situation, then the consistency of haptic perception is improved, but the device complexity increases
Solution Approach 1:
The system performs self-adjustment of haptic parameters by automatically acquiring context information about the user's state and situation, then autonomously modulating the control signal accordingly. This self-service approach eliminates the need for complex manual configuration interfaces, reducing perceived device complexity while maintaining perception consistency.
Solution Approach 2:
The system implements a feedback loop where context information about user state is continuously acquired and used to adjust haptic parameters. This automatic feedback mechanism replaces complex manual adjustment systems, achieving consistent haptic perception through automated closed-loop control rather than increased device complexity.
