Gesture-Controlled Beverage Machine Interface to Prevent Pathogen Spread
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation devices with touch-sensitive interfaces can transmit infectious diseases like the common cold and flu due to direct user interaction, and they do not encourage physical activity, which is beneficial for health.
Innovation Solution
A control unit for automatic beverage preparation devices that uses image input means, such as cameras, to detect user movements and generate control signals for preparing beverages without direct contact, promoting physical activity by requiring minimum movement standards, especially vertical movements, and providing visual and auditory feedback to enhance user engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch-sensitive interface is used for beverage preparation, then ease of operation is improved, but pathogen transmission risk increases
Solution Approach 1:
The patent introduces an image input means (camera) as an intermediary device that captures images of the user and their movements. This intermediary system translates physical gestures into control signals without requiring direct contact between the user and the beverage preparation device, thereby eliminating pathogen transmission while maintaining ease of operation.
Solution Approach 2:
The patent replaces the mechanical touch-sensitive interface with an optical-based image recognition system. Instead of requiring physical contact with buttons or touchscreens, the system uses a camera to detect and interpret user gestures, substituting mechanical interaction with optical detection and image processing.
2Ease of operation
If minimal user effort is required for operation, then ease of operation is improved, but physical inactivity increases
Solution Approach 1:
The patent implements a dynamic interaction system where the device adapts to various user gestures and movements. The image input means captures a range of motion patterns, and the control system interprets different types of movements (arm waving, hand gestures, body movements) to control beverage preparation, encouraging users to engage in more varied and active physical interactions.
Solution Approach 2:
The system provides visual feedback by displaying captured images and movement recognition status on a display element. This feedback mechanism confirms to users that their movements are being detected and interpreted, encouraging them to continue engaging in physical activity while operating the device.
