Solution Overview
Problem
Users in various environments, such as industrial settings or homes, often struggle to detect and respond to vibrations and sounds due to limitations in perception, hearing, or physical capabilities, which can lead to safety issues and difficulties in performing tasks effectively.
Innovation Solution
A wearable display device (WDD) equipped with environmental sensors detects vibrations and sounds, identifies alert conditions, and generates augmented notifications to guide users, providing proactive contextual information and improving reaction times and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users rely on natural hearing and vision to detect vibrations and sounds, then the system complexity remains low, but the detection capability and safety awareness are insufficient
Solution Approach 1:
The patent introduces an intermediary system consisting of vibration sensors, audio sensors, and a notification device that mediates between the environmental vibrations/sounds and the user's perception. This intermediary system enhances detection capability by capturing and processing environmental signals that the human senses might miss, while maintaining manageable system complexity through modular sensor integration and signal processing algorithms.
2Loss of time
If users are provided with detailed environmental information, then the awareness and reaction time improve, but the information processing load and distraction increase
Solution Approach 1:
The patent extracts only the most critical vibration and sound parameters from the complex environmental data stream. Instead of presenting all environmental information, the system identifies and extracts salient features such as vibration amplitude thresholds, sound level cutoffs, and pattern recognition markers that indicate alert conditions. This selective extraction reduces information processing load while maintaining effective user awareness and rapid reaction time.
Solution Approach 2:
The system implements feedback mechanisms where vibration and audio sensors continuously monitor the environment, process the data through alert condition evaluation, and provide timely notifications to the user. This closed-loop feedback system ensures that users receive information at the moment it becomes relevant, optimizing reaction time while the automated processing handles the complexity of continuous environmental monitoring.
3Reliability
If the notification system provides comprehensive environmental data, then the user awareness improves, but the user attention and focus are diverted from tasks
Solution Approach 1:
The patent applies partial action by providing only the essential notification information needed for user awareness and safety, rather than overwhelming users with comprehensive environmental data. The system selectively notifies users of alert conditions that require attention, such as excessive vibrations or dangerous sound levels, while filtering out redundant information. This partial notification approach maintains reliable user awareness of critical conditions while preserving user focus on their primary tasks.

Function Achieved in This Case
The system enhances user safety and awareness by providing timely and relevant notifications, allowing users to react appropriately to environmental vibrations and sounds, even in situations where they may not be able to hear or see the source directly.
Implementation Method 1
One or more environmental vibrations that originate from a vibration source are detected by a wearable display device
Data Source
AI summary
One or more environmental vibrations that originate from a vibration source are detected by a wearable display device. The wearable display device is worn by a user. The vibration source is located in an environment that is proximate to the wearable display device. An alert condition related to the vibration source is identified, based on the one or more environmental vibrations. An augmented notification for the wearable display device is generated in response to the alert condition. The augmented notification provided, by the wearable display device, to the user.
