Situation Awareness: Classic Levels and New Concepts in XR4DRAMA

At the core of our project, there is always situation awareness (SA). Just in case the term is not familiar yet: SA describes how humans perceive the elements of a given environment within spatial and temporal confinements – and how that perception affects their performance and decision-making in the situation at hand. SA has become particularly important where decision-making happens under time pressure, remotely or among multiple operators, e.g. at a public authority managing natural disasters and sending out first responders – or at a media organization preparing for an outdoor TV production.

Perception, Comprehension, and Projection

Classic models – like the one that goes back to Mica Endsley – define three levels of SA:

  1. Perception

    The first and most basic level of SA is about monitoring, spotting, and recognizing things. L1SA is achieved as agents become aware of different elements a situation
    (e.g. other people and objects) and are also able to detect their status (condition, location etc.).
  1. Comprehension

    The second level of SA is about recognizing, interpreting, and evaluating the lie of the land. L2SA is achieved when agents understand what is going on around them (at present) – and what that means for their objectives.

  2. Projection

    The third and highest level is about projections and predictions. L3SA is achieved when agents extrapolate the information they have collected in L1SA and L2SA and are thus able to gain insights on what the situation (and elements therein) will probably look like in the future – and in what ways the mission may have to be adjusted.

Endsley’s model has been criticized, revised and extended since it was first published in 1995, but for the sake of simplicity – and because this is not an academic forum – we will not go into further details. Instead, we would rather like to briefly explain how the three levels of SA in XR4DRAMA are both similar to and different from the influential classic model outlined above.

Increasingly sophisticated renderings of locations

on a location (L2SA) – but no immersive mode (L3SA) yet.

XR4DRAMA wants to build a digital platform for people who are – remotely or directly – planning for and dealing with events and incidents in a specific location. Just like in the classic model, the XR4DRAMA SA levels will be subsequent ones that build on each other and go from low to high complexity. However, while Endsley et al. start out with simple perception and aim for sophisticated projections, the XR4DRAMA platform will rather focus on providing as much information as possible to achieve good enough or very good comprehension. That being said, the level of detail will always depend on the specific use case and the time that is available to users of the platform.

In any case, the consortium foresees a platform that makes use of three different levels:

  1. Simple Mode

    XR4DRAMA L1SA will be a simple, yet appealing visualisation/representation of a location that includes first information on geography, sociographics etc. as well as a couple of images and/or videos. L1SA is created automatically and relies on data from a number of (publicly available) web services.

  2. Enhanced Mode

    XR4DRAMA L2SA will be an enhanced visualisation/representation that draws on recent, exclusive content and updated information stemming from people with gadgets and sensors who are operating in the field (first responders or location scouts). We will have the XR4DRAMA system process their data and combine it with what has already been collected and visualized for  XR4DRAMA L1SA.

  3. Immersive Mode

    XR4DRAMA L3SA will be a complex and comprehensive representation of a specific location, close to a simulation of an event within that environment. Here, the platform aggregates all the information from L1SA and L2SA and also allows users to immerse themselves in the situation via VR or AR features and tools (with a possible extra focus on more sophisticated audio). Ideally, this representation also enables test runs of specific strategies and methods ( e.g. the simulation of camera movements in the media use case), thus connecting with the concept of projection/prediction in classic L3SA.

In general, the consortium envisions a solution where all levels and functions are accessible to all stakeholders in a scenario, albeit in graduations and on different devices (because nobody wants to wear a VR google in the field). As already mentioned on the project vision page, the ultimate dream is to create a platform that enables shared, distributed SA.

Hello world, this is XR4DRAMA!

19 (out of 27) members of the XR4Drama consortium representing 7 organizations from 4 countries.

We just wanted to let you know that our EU-funded Innovation Action (IA) has been officially kicked off! November 25th and 26th saw us meet online to discuss and organize all the research, development and communication tasks that lie ahead in the next two years. Using XR technology (and lots of data) for a new kind of situational awareness means breaking uncharted territory – but it looks like we’re well prepared.

We had a long, productive, enjoyable  video conference – with only one drop of bitterness: Everybody would’ve loved to meet afk/irl in Thessaloniki (where XR4DRAMA coordinator CERTH is headquartered) – and go for social dinner at the end of the business day. Maybe that will happen sometime in 2021 or 2022, fingers crossed.

Getting back to the IA itself, you can already read quite a bit about the project vision on this page. And to learn more about the consortium behind XR4DRAMA, just go here.

This blog section will keep you up-to-date with regard to deliverables, milestones, insights, prototypes, events, and so on. The next couple of posts will give you a more elaborate intro to the concept of situational awareness and describe the two pilot use cases we have in store.

So stay tuned. And don’t forget to join the conversation on Twitter and Linkedin!

Best regards from Athens, Barcelona, Berlin, Bonn, Cologne, Prato, Thessaloniki, and Venice,

The XR4DRAMA Consortium
