The Solution

Screen Door Laboratories focused on creating an interface where first responders can actively interact with real-time data, completely hands-free. The interface, ARfocus, empowers first responders to “click” into different features with eye gaze, which functions as a cursor on the AR headset. To “click,” users simply look at an icon for it to be triggered; and to “unclick,” they simply look away.

Accompanying text: The 3D map has different datasets for the commanders to toggle on and off.
Three interface screens side by side demonstrating how to "click" with the middle screen showing white, green, blue, and red buttons with a person icon in the middle simulating a "click." Accompanying text reads: to "click," user simply look at a dot for it to be triggered; to "unclick," they simply look away.

Key Features

  • ARfocus Crew View: Featuring a minimalistic design, with only a four-dot menu and a compass belt, it promises to never distract users from the real world. By looking at each dot, users can activate messages, check maps, and leave time-stamped bookmarks. These bookmarks (indicating patients, personnel, or resources) are automatically saved and sent with GPS data. All of the captured data becomes accessible by other crew members and commanders.
  • ARfocus Commander View: Equipped with four 2D panels and a 3D map, the commander view thrives on being the one-stop shop for commanders. They can see the status of crews, message them, and have a high-level view of the moving pieces. Bringing commanders’ whiteboards into the virtual space allows commanders to stay in the headset, visualizing data in real-time. Based on different disaster scenarios, the 3D map has different datasets for the commanders to toggle on and off. The ARfocus data broker processes over 2,000 points of data per second.
