VR-MARS Virtual Reality, Medical Assistance and Rescue for Space

Study Overview
=================
Brief Summary
-----------------
VRMARS is a medical simulation study in microgravity. Healthy volunteers (n=18) test in microgravity the functionnality of an augmented reality headset in which a medical assistance is displayed.

| Experimental: Augmented Reality Headset Usability<br>In this arm, participants tested the functionality and usability of the headset (a Microsoft Hololens 2 or a Varjor XR3) | Device: Augmented Reality Headset / Hololens 2 or Varjo XR3<br>* Augmented Reality Headset<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Technical validation of the headset in microgravity | The participant had to report to the invistigators whether the headset functioned under microgravity. Images superimposed on the real environment had to be correctly placed and stable in zero-G | 1 day | 
| Usability test HARUS / Form | The HARUS (Handheld Augmented Reality Usability Scale) is a questionnaire measuring manipulability -- the ease of handling the HAR system, and comprehensibility -- the ease of understanding the information presented by augmented reality. | 1 day | 
| NASA-TLX cognitive test | The NASA TLX is a subjective, multidimensional assessment tool that rates perceived workload in order to assess a task, system, or team's effectiveness or other aspects of performance (task loading) | 1 day |
