Solution Overview
Problem
Existing technologies fail to effectively capture and relay haptic feedback from one device to another, particularly in gaming and virtual reality applications, where the feedback is often lost shortly after it is provided.
Innovation Solution
A method and system that utilize a haptic relay device with sensors to detect haptic feedback, such as vibration, and convert it into an electrical signal for wireless transmission to a target device, allowing the device to actuate corresponding actions that can be sensed by the user, including varying frequency and intensity based on the original feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If haptic feedback is provided in the game controller, then user feedback is delivered, but the feedback is lost shortly after it is provided
Solution Approach 1:
An intermediary system consisting of sensors, signal processing circuitry, and communication modules is introduced to capture haptic feedback from the game controller and relay it to a second device. This mediator prevents the natural loss of haptic feedback by transferring the signal to another device where it can be preserved and retransmitted.
Solution Approach 2:
The haptic feedback signal is captured and copied from the original game controller to a second device through wireless or wired communication. This creates a duplicate of the haptic feedback that can be stored, transmitted, and replayed, preventing the original signal from being lost after provision to the user.
2Duration of action of stationary object
If haptic feedback is captured and relayed to another device, then feedback persistence is achieved, but device complexity increases
Solution Approach 1:
The relay device is designed with multi-functionality, serving as both a haptic feedback receiver and transmitter, and potentially as a processing unit. This universal approach consolidates multiple functions into a single device, managing complexity rather than increasing it through distributed components.
Solution Approach 2:
The system enables self-service by allowing the second device to autonomously receive, process, and retransmit haptic feedback signals without requiring constant external intervention or complex external control systems. The relay device independently manages the feedback persistence function.
3Measurement precision
If sensors are used to detect haptic feedback, then feedback capture accuracy is improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs cost-effective, readily available sensors (such as accelerometers) that can be easily manufactured and integrated into the relay device. These sensors are chosen for their availability and ease of integration rather than high precision or longevity, balancing manufacturing ease with sufficient detection accuracy for haptic feedback.
