Handheld 3D Interface for Sterile Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D visualization systems in medical and industrial applications require physical interaction, which poses risks of cross-contamination and is inconvenient in dirty or sterile environments, as they necessitate the use of touch-based user interfaces for controlling 3D views.
Innovation Solution
A system integrating 3D user interface functionality into a handheld device that allows remote control of 3D environment views on a display, enabling the operator to perform actions in a physical 3D environment while maintaining a sterile or clean environment, using motion sensors and actuators to switch between action and control modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical touch-based user interface devices are used for controlling 3D views, then ease of operation is improved, but risk of cross-contamination and harmful factors increases
Solution Approach 1:
The patent introduces motion sensors as an intermediary between the user and the 3D visualization system. The sensors detect hand gestures and body movements in the air space around the display, translating these physical motions into digital control commands without requiring direct contact with the touchscreen interface. This mediator layer enables touchless operation while maintaining intuitive control over 3D medical images.
Solution Approach 2:
The patent replaces the mechanical touch-based interface system with a motion detection system. Instead of requiring physical contact with buttons or touchscreen elements, the system uses optical or electromagnetic sensors to detect gestures in three-dimensional space. This substitution eliminates the mechanical contact point that would otherwise serve as a vector for pathogen transmission.
2Adaptability or versatility
If separate user interface devices are used for 3D view control, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent merges the 3D visualization display system with motion sensing capabilities into a single integrated unit. The motion sensors are embedded within or positioned as part of the display assembly, allowing the same system to both present medical images and detect controlling gestures. This consolidation eliminates the need for separate handheld controllers or external gesture recognition systems.
Solution Approach 2:
The display system is designed to serve multiple functions: it acts as both the visualization screen for 3D medical images and the control interface through integrated motion sensors. The same physical device that displays diagnostic information also captures gesture data, processes control commands, and adjusts viewing parameters, making the system universal rather than requiring specialized separate devices.
