Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tactile reproduction systems that sense and reproduce tactile information, such as vibrations, are complex and costly, making them unsuitable for general user applications.
Innovation Solution
A signal generation device that utilizes an angular velocity sensor from an imaging device to generate tactile signals, eliminating the need for separate motion detection units by converting angular velocity into displacement or angle signals, and synchronizing these with visual information to provide a realistic tactile experience.

Engineering Contradiction Analysis
1Reliability
If a separate motion detection unit is added to sense tactile information for reproduction, then the tactile information reproduction capability is improved, but the system complexity and cost increase
Solution Approach 1:
The imaging device's angular velocity sensor, originally designed for camera shake correction, is repurposed to detect motion for tactile signal generation. This allows the same sensor to serve dual functions: optical stabilization and tactile information acquisition, thereby avoiding additional hardware components and reducing system complexity
Solution Approach 2:
The imaging device generates its own tactile signals using its built-in angular velocity sensor without requiring external motion detection equipment. The device serves itself by utilizing its existing resources (sensor and processing capability) to create tactile reproduction functionality, eliminating the need for separate motion detection units
2Reliability
If a separate motion detection unit is added to sense tactile information for reproduction, then the tactile information reproduction capability is improved, but the cost increases
Solution Approach 1:
The angular velocity sensor in the imaging device performs both camera shake correction and tactile signal generation functions. By making the sensor multi-functional, the system avoids the need for additional expensive components, thereby reducing manufacturing costs while maintaining tactile reproduction capability
Solution Approach 2:
The imaging device utilizes its own existing angular velocity sensor and processing capabilities to generate tactile signals, eliminating the need to purchase and integrate separate motion detection units. This self-sufficient approach reduces overall system cost while achieving the desired tactile reproduction functionality

AI summary
To achieve simplification in configuration and reduction in cost of a tactile reproduction system that reproduces tactile information. The signal generation device according to the present technology includes a signal generation unit that generates a tactile signal on the basis of a detection value of a motion detection unit that is provided in an imaging device and detects motion of the imaging device. This eliminates the need to provide a separate motion detection unit other than the motion detection unit provided in the imaging device in order to realize a system that reproduces tactile information together with visual information.
