Teleoperation Haptic Menu Feedback for Surgical GUI Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Teleoperational medical systems lack effective haptic feedback mechanisms when navigating graphical user interfaces, which can lead to user disorientation and reduced operational efficiency during minimally invasive procedures.
Innovation Solution
A method that applies haptic forces to control devices to simulate a nominal position, an engaged operational state, and a return to the nominal position, providing tactile feedback indicative of menu item selection and navigation through graphical user interfaces, enhancing user interaction and immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If graphical user interfaces are used to control teleoperated medical tools, then the functionality of the system is extended without adding structural controls, but the user experiences disorientation and reduced operational efficiency due to lack of haptic feedback
Solution Approach 1:
The system applies haptic feedback forces to the control device to provide tactile cues to the user during menu navigation. When a menu item is selected, a haptic force is applied to indicate the selection state, giving the user sensory feedback that confirms their input and reduces disorientation when using graphical interfaces.
2Device complexity
If graphical user interfaces are used instead of additional structural controls, then the device complexity is reduced, but the user experiences reduced operational efficiency during menu navigation
Solution Approach 1:
Haptic feedback is applied to the control device to provide tactile confirmation during menu navigation. This feedback mechanism improves operational efficiency by giving users sensory confirmation of their selections and system state, enabling faster and more accurate interaction with the graphical interface without adding physical controls.
3Ease of operation
If haptic feedback is applied to indicate menu item selection, then user interaction is improved with clear tactile cues, but the system requires additional haptic control mechanisms
Solution Approach 1:
The haptic feedback functionality is merged with the existing control device that is already used to manipulate medical instruments. The same control device provides both instrument control and menu navigation with haptic feedback, eliminating the need for separate haptic feedback mechanisms and reducing overall system complexity.
Solution Approach 2:
The control device is designed to serve multiple functions: it controls medical instruments during surgical procedures and also navigates graphical user interface menus with haptic feedback. This multi-functionality reduces the need for additional dedicated controls while improving user interaction.

AI summary
A haptic feedback method comprises providing a teleoperational control system including a first operational mode for operating a teleoperational instrument in response to movement of a control device in a first degree of freedom and a second operational mode for controlling a graphical user interface. The method also includes engaging the second operational mode of the teleoperational control system. While in the second operational mode, the method includes tracking movement of the control device of in a second degree of freedom, different from the first degree of freedom. While in the second operational mode and responsive to the movement of the control device in the second degree of freedom, the method includes applying, by a teleoperational control system, a first haptic force to the control device.
