Head-Mounted Display Emergency Notification Visual Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighters and other workers in emergency situations may fail to perceive emergency notifications due to ambient noise or movement, making existing vibration-based systems ineffective.
Innovation Solution
An information processing apparatus with a notification transmitting unit and a display control unit that transmits emergency notifications and displays them on a head-mounted display, ensuring visual recognition even during movement or in noisy environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vibration-based notification is used, then the notification can be transmitted to workers, but the worker cannot perceive the notification when moving their body during work
Solution Approach 1:
The patent replaces the mechanical vibration-based notification system with an optical display system. The head-mounted display shows notification icons and information visually, eliminating the unreliability of vibration perception during movement. This substitution ensures notifications are always perceivable regardless of the worker's physical state.
Solution Approach 2:
The patent introduces a head-mounted display as an intermediary device between the notification system and the worker. This intermediary converts vibration signals into visual representations that can be perceived by the worker's vision system, which remains functional even when the worker is moving their body during firefighting operations.
2Reliability
If vibration-based notification is used, then the notification can be transmitted, but the notification cannot be perceived in noisy environments
Solution Approach 1:
The patent substitutes the acoustic/mechanical vibration notification with an optical display notification. The head-mounted display presents visual information that is immune to ambient noise interference, allowing workers to perceive notifications clearly even in noisy firefighting environments where vibration signals may be masked or imperceptible.
3Loss of information
If visual display on head-mounted display is used, then accurate recognition of emergency notification is achieved, but the device complexity increases
Solution Approach 1:
The patent integrates the notification display function into the existing head-mounted display device already worn by firefighters for other purposes. By utilizing this existing universal device, the system achieves accurate visual notification without significantly increasing overall device complexity, as the display infrastructure is already in place.
Solution Approach 2:
The patent merges the emergency notification function with the existing head-mounted display system. Instead of adding a separate notification device, the notification icons and information are combined with the display already present on the worker's helmet, thereby achieving accurate notification recognition while minimizing additional complexity.

AI summary
An information processing apparatus, a method for processing an emergency notification, and a program capable of enabling, when an emergency situation for a worker occurs, the worker to accurately recognize a state of issuance of an emergency notification are provided. An information processing apparatus includes a notification transmitting unit configured to transmit an emergency notification when a predetermined condition is satisfied, the emergency notification being a notification for reporting an occurrence of an emergency situation for a worker, and a display control unit configured to perform control so as to display information about the emergency notification on a head-mounted display.
