Portable Device Emergency Alert Notification for Hearing Impaired
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcast technologies for emergency alerts do not effectively notify users with disabilities, such as visual or hearing impairments, as they require users to actively tune into specific channels, which can be challenging for individuals with disabilities.
Innovation Solution
A mechanism that notifies users of emergency alerts on networked portable devices without ongoing polling, using telephony radio networks and broadcast technologies, providing alerts through visual, auditory, or mechanical feedback, and optionally presenting emergency information in sign language.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If broadcast technologies are used for emergency alerts, then emergency alert notification can be provided to wireless subscribers, but users with disabilities cannot effectively receive the alerts because they require active tuning to specific channels
Solution Approach 1:
The system automatically detects emergency alert broadcasts and delivers them to users without requiring any action from the user. The portable device autonomously monitors for emergency alerts, retrieves the information, and presents it through appropriate accessibility interfaces, eliminating the need for users to manually tune channels or activate specific functions.
Solution Approach 2:
The system introduces an intermediary notification mechanism that bridges the gap between broadcast emergency alerts and users with disabilities. This intermediary automatically receives the broadcast alerts, processes them, and delivers them through accessible formats (visual, auditory, or tactile feedback), serving as a mediator that adapts the broadcast content for users who cannot actively access traditional broadcast channels.
2Reliability
If continuous monitoring of emergency communication channels is implemented, then users can receive timely emergency alerts, but battery life is depleted and network bandwidth is consumed
Solution Approach 1:
Instead of continuous monitoring, the system employs periodic polling at optimized intervals to check for emergency alert broadcasts. This periodic approach maintains the ability to detect alerts timely while significantly reducing energy consumption compared to continuous monitoring, as the device can enter low-power states between polling intervals.
Solution Approach 2:
The system uses feedback mechanisms where the portable device monitors for specific indicators that an emergency alert is being broadcast, then activates full retrieval and notification only when such indicators are detected. This feedback-driven approach allows the device to remain in a low-power state during normal conditions while ensuring timely alert reception when needed.
3Loss of information
If emergency alerts are provided through traditional broadcast channels, then alert information can be transmitted, but users with hearing or visual impairments cannot access the information effectively
Solution Approach 1:
The system applies different presentation modalities tailored to individual user needs and disability types. Visual alerts are provided through display screens for hearing-impaired users, auditory alerts through speakers for visually-impaired users, and tactile alerts through vibration motors for users with both visual and hearing impairments. This localized adaptation of information presentation ensures effective communication for each user's specific needs.
Solution Approach 2:
The system implements multi-functional alert delivery capabilities that can present emergency information through multiple sensory channels (visual, auditory, tactile) simultaneously or alternatively. This universal approach ensures that regardless of a user's specific disability, the emergency alert information remains accessible through at least one appropriate modality, making the system adaptable to diverse user needs.
Data Source
AI summary
An indication of an emergency alert message is provided to a user, potentially having a disability, via a networked enabled portable device. The emergency alert message is provided via sign language video images indicative of the emergency alert. A notification makes the user aware when broadcast emergency alerts are issued. In various embodiments, the portable device is enabled to receive information about an emergency alert broadcast of which the potentially disabled user should be aware, e.g., from the EAS, and to notify the user of the emergency alert. The user can be automatically taken to the emergency alert information by having the portable device automatically tune to the emergency broadcast information, the user can optionally retrieve the emergency information by tuning to the emergency broadcast channel, and/or the user can otherwise be presented with a reference to the emergency data, such as a link to the information.
