Solution Overview

Problem

Existing robotic control systems face challenges in maintaining intuitive operation when the point-of-view of an imaging sensor changes, leading to inconsistencies in user interface control directions and haptic feedback, as the operator's frame of reference varies with sensor position and orientation.

Innovation Solution

A method and system that dynamically modify control and haptic feedback signals based on the imaging sensor's point-of-view, ensuring that user interface inputs align with the operator's frame of reference by performing directional translations of both control and haptic feedback directions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the imaging sensor's point-of-view changes, then the operator's frame of reference changes, but the control direction and haptic feedback direction become inconsistent with the operator's expectations

Engineering Contradiction:

Improveadaptability to changing point-of-viewVSAvoidintuitive control consistency

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts the directional translation matrices based on the current point-of-view of the imaging sensor. As the sensor moves or rotates, the translation matrices are updated in real-time to maintain consistency between the control directions and the operator's frame of reference, resolving the contradiction between adaptability and operational intuitiveness

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameters of the directional translation by computing new translation matrices that account for the updated point-of-view. This involves transforming the control directions and haptic feedback directions using the current sensor orientation and position, ensuring that the operational characteristics remain consistent despite changes in the imaging perspective

2Ease of operation

If directional translation is performed based on imaging sensor point-of-view, then control consistency is improved, but system complexity increases

Engineering Contradiction:

Improvecontrol direction consistencyVSAvoiddirectional translation processing

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system replaces complex mechanical reconfiguration with computational processing. Instead of physically reorienting control elements when the point-of-view changes, the system uses directional translation matrices to computationally adjust the control signals, simplifying the overall system architecture while maintaining control consistency

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The directional translation matrices serve as an intermediary layer between the user interface controls and the robotic manipulator actuators. This intermediary transforms control directions and haptic feedback directions based on the current point-of-view, isolating the complexity of coordinate transformations from both the user interface and the actuator control

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 1:

The system pre-computes the directional translation matrices based on the imaging sensor's point-of-view. By preparing these transformation matrices in advance or maintaining them in a ready state, the system minimizes the processing time required during real-time operation while ensuring accurate haptic feedback translation

AI summary

Method and system for telematic control of a slave device. Displacement of a user interface control is sensed with respect to a control direction. A first directional translation is performed to convert data specifying the control direction to data specifying a slave direction. The slave direction will generally be different from the control direction and defines a direction that the slave device should move in response to the physical displacement of the user interface. A second directional translation is performed to convert data specifying haptic sensor data to a haptic feedback direction. The haptic feedback direction will generally be different from the sensed direction and can define a direction of force to be generated by at least one component of the user interface. The first and second directional translation are determined based on a point-of-view of an imaging sensor.
