Solution Overview
Problem
Existing systems for providing tactile sensory information to users, such as those using multiple cameras, are inefficient and may not accurately detect objects based on user interaction, particularly when determining object positions on a screen.
Innovation Solution
A 4D technology-based system that employs a sensor-equipped tactile device to detect motion and transmit motion information to a display device, which then extracts and transmits tactile information to the user, allowing for accurate object detection and sensory feedback without relying on multiple cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are used to detect tactile sense-providing device, then object detection capability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the detection function from multiple cameras and consolidates it into a single tactile sense-providing device equipped with sensors. This removes the need for complex multi-camera systems while maintaining detection capability, directly resolving the contradiction between detection accuracy and system complexity.
Solution Approach 2:
The tactile sense-providing device is designed to perform multiple functions: it provides tactile feedback to the user while simultaneously serving as the detection device with sensors. This multi-functionality eliminates the need for separate detection systems, reducing overall system complexity while maintaining detection precision.
2Reliability
If multiple cameras are installed on television, then tactile detection capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent extracts the tactile detection function from the television system and relocates it to a separate, portable sense-providing device. This extraction simplifies television manufacturing while maintaining reliable tactile detection through dedicated sensors in the portable device.
Solution Approach 2:
The tactile sense-providing device is designed as a self-contained unit with integrated sensors and processing capabilities. It independently performs detection and feedback functions without requiring complex integration with the television system, thereby simplifying manufacturing for both the television and the detection device.
3Measurement precision
If motion information from sense-providing device is used, then object detection accuracy is improved, but processing complexity increases
Solution Approach 1:
The patent implements a feedback loop where motion information from the sense-providing device is continuously monitored and used to update object detection in real-time. This feedback mechanism improves detection accuracy by correlating device motion with object position, while the processing complexity is managed through efficient algorithms that leverage the structured nature of tactile sensor data.
