Exploring the Design Space of Optical See-through AR Head-Mounted Displays for First Responders in the Field

Główne pojęcia

The author explores the design space of optical see-through AR head-mounted displays to support first responders by involving various roles and addressing specific needs, while also highlighting concerns around trust, privacy, and integration with existing equipment.

Streszczenie

The study delves into the preferences and needs of first responders regarding AR hardware, interactions, and feedback. It reveals role-specific insights and proposes actionable design guidelines for future AR systems tailored to emergency response scenarios.
First responders navigate hazardous environments, making split-second decisions. AR HMDs show promise but require thorough exploration. The study involved 26 first responders experiencing state-of-the-art AR HMDs. Generic and role-specific preferences were identified for hardware, interactions, and feedback. Concerns around trust, privacy, and integration with equipment were raised. Comprehensive design guidelines were derived to inform future AR systems for in-field first responders.

Statystyki

FRs include disciplines like firefighters (FF), law enforcement (LE), emergency medical services (EMS).
Three disciplines—FF, LE, EMS—commonly work in the field.
2D maps preferred over 3D maps for urgent scenarios.
Firefighters desired back-tracing cues in visually challenging environments.
Paramedics needed subtle directional cues for driving emergency vehicles.
Real-time marking proposed for collaboration among team members.
Outdoor navigation suggested an AR compass on the ground.
Firefighters preferred outlining egress points over shaded overlay.
EMS and LE favored shaded overlays for highlighting smaller objects.

"Having furniture on the map could be a hindrance...a structural unchanging layout would be more valuable." - Participant 6
"I think having arrows [during firefighting] would be pretty serious situation...for driving situation you do want it pretty low-key." - Participant 5

How can AR technology address privacy concerns when integrated with existing equipment?

Integrating AR technology with existing equipment in a way that addresses privacy concerns involves several considerations. One approach is to implement features that prioritize data security and user privacy, such as encryption of sensitive information transmitted through the AR system. Additionally, providing users with control over their personal data and ensuring transparent data handling practices can help build trust.
Another strategy is to design the AR system in a way that minimizes the collection and storage of unnecessary personal information. By only capturing essential data for the task at hand and implementing strict access controls, the risk of privacy breaches can be reduced. Furthermore, incorporating features like anonymization or pseudonymization of user data can add an extra layer of protection.
In terms of physical integration, ensuring that any cameras or sensors on the AR device are used responsibly and ethically is crucial. This may involve implementing mechanisms to disable certain functionalities in sensitive environments or situations where privacy could be compromised. Providing clear guidelines on when and how these devices should be used can also help mitigate potential privacy risks.

What are potential challenges in implementing real-time marking features for collaboration among team members?

Implementing real-time marking features for collaboration among team members presents several challenges that need to be addressed for effective use:

Accuracy: Ensuring the accuracy of real-time markings requires precise tracking and mapping capabilities to correctly overlay digital markers onto physical spaces.

Data Synchronization: Maintaining synchronization between team members' devices to ensure they see consistent real-time markings poses a technical challenge, especially in dynamic environments.

User Interface Design: Designing an intuitive interface for adding, viewing, and interacting with real-time markings is essential for usability during high-pressure situations.

Collaboration Tools Integration: Integrating real-time marking features with existing communication tools used by first responders may require interoperability considerations.

Training & Adoption: Training all team members on how to effectively use real-time marking features and encouraging adoption across different roles within emergency response teams can be challenging.

Addressing these challenges will require close collaboration between designers, developers, end-users (first responders), and stakeholders throughout the development process.

How might the use of highlighting cues differ between indoor and outdoor emergency response scenarios?

The use of highlighting cues may vary between indoor and outdoor emergency response scenarios due to differences in environmental factors:
Indoor Scenarios:

In indoor scenarios such as building fires or search-and-rescue operations inside structures, highlighting cues are often used to identify critical elements like exits, hazards (e.g., gas leaks), victims' locations, or structural details (e.g., doors).
Highlighting cues indoors may focus more on specific objects within confined spaces where visibility is limited due to smoke or darkness.
Outlines may be preferred indoors as they provide clear delineation without obstructing detailed information about objects like door types or room layouts.
Outdoor Scenarios:

In outdoor scenarios like wilderness searches or large-scale incidents involving open areas, highlighting cues could emphasize landmarks (e.g., trails) points-of-interest (e.g., water sources), hidden dangers (e.g., cliffs), suspect locations during law enforcement operations outdoors.
Shaded overlays might be more suitable outdoors where there's ample space since they provide broader coverage over larger areas compared outlines which work better indoors where precision matters more than broad coverage
The scale at which highlights appear would likely differ outdoors compared indoors due vastness difference
Adapting highlighting cue designs based on these environmental factors ensures optimal support for first responders navigating diverse emergency situations both indoors ad outdoorts
