Solution Overview
Problem
Existing human-machine interactions, particularly in industrial settings, pose safety risks and productivity deficits due to suboptimal coordination, necessitating improved safety and productivity in human-machine interactions.
Innovation Solution
An augmented reality system that integrates a detection unit for capturing the real environment, a communication unit for receiving process data, a control unit for processing data to create a virtual image, and an audio output unit for contextually matched audio signals, enhancing user instruction and safety through synchronized visual and auditory cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If human-machine interaction is increased for better coordination, then productivity is improved, but safety risks and accident probability increase
Solution Approach 1:
The patent introduces an augmented reality system as an intermediary between the human operator and the machine (robot). This AR system provides visual overlays with safety information, hazard warnings, and operational guidance, mediating the interaction to enhance both productivity and safety simultaneously rather than allowing direct unmediated interaction that increases risk
Solution Approach 2:
The system implements continuous feedback loops where the AR display provides real-time information about the robot's status, intended actions, and safety zones. This feedback mechanism allows the operator to maintain situational awareness and respond appropriately, preventing accidents while maintaining high interaction levels for productivity
2Loss of information
If visual information is provided to instruct the user, then instruction quality is improved, but misinterpretation risk increases due to lack of contextual audio support
Solution Approach 1:
The patent merges multiple information channels by combining visual displays (AR overlays showing operational status, safety zones, and instructions) with audio output (verbal instructions and warnings). This multi-sensory approach reinforces the same information through different modalities, reducing misinterpretation risk while maintaining high instruction quality
Solution Approach 2:
The system provides differentiated information quality for different user needs and contexts. The AR display and audio output can be customized to provide detailed information for complex operations or simplified warnings for routine tasks, adapting the local quality of information delivery to match the specific instructional context and user competency level

AI summary
The present invention relates to an augmented reality (AR) system for instructing a user of an application. The AR system comprises a sensor unit that captures a real environment and provides it as environmental data, wherein at least one work unit is arranged in the environment; a communication unit that receives process data from the work unit; a control unit that processes the process data and environmental data, wherein a virtual image can be created based on the process data; and a display unit that shows the real environment and the virtual image to a user in relation to each other. Furthermore, the AR system comprises an audio output unit that outputs audio signals for instructing a user based on the process data, wherein the audio signals are preferably synchronized with the virtual image.
