Remote Touch Replication via Segmented Haptic Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote touch systems fail to simulate the desired feeling or sensation of touch and are susceptible to communication network issues, leading to a poor user experience.
Innovation Solution
A system comprising a first device with a touch sensor and a haptic terminal connected via a communication network, where the first device captures data on sliding movements and sends it to the haptic terminal to replicate touch sensations, such as a caress, using a processing unit and touch replicator, even with communication network issues.

Engineering Contradiction Analysis
1Reliability
If conventional remote touch systems are used to enable emotional connection over distance, then communication between remote people is established, but the systems fail to simulate the desired feeling or sensation of touch
Solution Approach 1:
The system segments the touch sensation into multiple independent parameters (position, pressure, speed, direction, contact area) that can be captured separately by sensors and replicated independently by actuators. This segmentation allows precise control over each aspect of the touch sensation to achieve realistic remote touch.
Solution Approach 2:
The system dynamically changes multiple parameters simultaneously to replicate different types of touch sensations. By adjusting pressure, speed, position, and contact area parameters in real-time, the system can simulate various touch types such as caressing, tapping, or gripping, making the remote touch experience more authentic.
2Adaptability or versatility
If remote touch systems are implemented using communication networks, then remote communication is enabled, but communication network issues like break or poor signal strength deteriorate user experience
Solution Approach 1:
The system performs preliminary actions by capturing and buffering touch data locally before transmission, and pre-loading replication patterns. This allows the system to maintain touch sensation continuity even when network communication is temporarily disrupted, as the haptic feedback can continue using previously captured data.
Solution Approach 2:
The system implements feedback mechanisms where the haptic terminal monitors network quality and adjusts its operation accordingly. When network conditions deteriorate, the system adapts by reducing data transmission frequency or using compressed representations, ensuring continuous user experience despite communication issues.
3Measurement precision
If touch sensors capture detailed sliding movement data for accurate touch replication, then touch sensation realism is improved, but data transmission requirements and system complexity increase
Solution Approach 1:
The system extracts only the essential parameters needed for touch replication from the raw sensor data, such as position, pressure, speed, and direction. By taking out only the critical information and discarding redundant data, the system maintains high measurement precision while reducing data transmission requirements and processing complexity.
