Summary

Assessing a user’s situation awareness can provide a great way to learn about the user’s mental model when performing related tasks. Situation Awareness Global Assessment Technique (SAGAT) is one widely accepted measure to objectively capture a user’s SA. In this work, we present our developed SAGAT probes to assess the situation awareness of blind individuals during indoor travel tasks. This work is part of our ongoing work to develop an objective method to facilitate blind travelers' situation awareness when traveling unfamiliar indoor environments. We present examples of our probes that were derived from our previously developed situation awareness requirements. Also, we briefly illustrate pilot study results with blindfolded participants.
