Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable computer systems pose challenges in clean and hygienic environments due to the need for hand interaction and non-visibility of integrated or remote displays, limiting user interaction and information access for individuals in manufacturing and medical settings.
Innovation Solution
An augmented reality head-mounted system with sensors and detectors that capture user gestures and environmental data, overlaying information through transparent displays, allowing hands-free interaction and enhanced visibility in various environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hand-held or wearable computer systems are used, then workers can move freely about the workspace and access information, but hand interaction is required which compromises hygiene in clean environments
Solution Approach 1:
The patent replaces manual hand interaction with voice commands and gesture recognition. The system uses microphones to capture voice inputs and cameras/sensors to detect hand gestures, converting mechanical hand operations into acoustic and optical signal processing, thereby eliminating direct hand contact with the device while maintaining full operational capability.
Solution Approach 2:
The patent introduces voice and gesture as intermediary control methods between the user and the computer system. Instead of direct hand contact with buttons or touchscreens, the system mediates user intent through voice recognition software and gesture detection algorithms, allowing hygienic interaction while preserving system control.
2Loss of information
If integrated or remote displays are used, then information can be displayed to users, but the displays are not visible in clean and hygienic environments
Solution Approach 1:
The patent employs displays with adjustable brightness and contrast settings that can be optimized for visibility in cleanroom environments. The system may also utilize color-coded information prioritization, displaying critical alerts in high-visibility colors while maintaining overall screen visibility without requiring physical contact with display surfaces.
Solution Approach 2:
The patent transitions from traditional 2D touchscreen interaction to 3D spatial gesture recognition. By detecting hand position, orientation, and movement in three-dimensional space using cameras and sensors, the system provides information access and control capabilities that don't require direct contact with the display surface, maintaining hygiene while ensuring information visibility.
3Ease of operation
If hand interaction is required for wearable computer systems, then full control capability is achieved, but user interaction is limited in clean and hygienic environments
Solution Approach 1:
The patent implements a universal control system that accepts multiple input modalities: voice commands for verbal instructions, gesture recognition for spatial commands, and limited touch interaction when necessary. This multi-functional interface maintains full control capability across different environments, adapting the primary interaction mode to environmental requirements while preserving all control functions.
Solution Approach 2:
The patent employs dynamic interaction mode switching that adapts to environmental context. The system can dynamically transition between voice-only mode, gesture-based mode, and hybrid modes based on environmental conditions, task requirements, and user preferences, ensuring ease of operation while maintaining adaptability to clean and hygienic settings.

AI summary
A method, system, apparatus, and/or device for moving or scrolling a virtual object in a virtual or augmented reality environment. The method, system, apparatus, and/or device may include: detecting, by a first sensor, a first gesture associated with selecting a first virtual object in an augmented reality environment displayed by a head-mounted display; displaying, by the head-mounted display, a first indicator indicating a selection of the first virtual object by a user; detecting, using the first sensor or a second sensor, a first movement of the head-mounted display associated with a first movement command; and in response to detecting the first movement of the head-mounted display, executing the first movement command, where the first movement command is a scrolling function to scroll text or a graphical object of the first virtual object or a movement function to move the text or the graphical object of the first virtual object.
