Amadee-20-HUMAIN

Details

Summary

The HUMAIN experiment studies the interaction between humans and machines, specifically
between the analog astronauts and the Aouda spacesuit simulator.
The field of HMI (human-machine interface) not only includes control devices such as switches,
keyboard or touchscreens; but also, the displaying of information, such as sound or graphical displays.
In particular, the ability to correctly and effectively display information plays a major role in high
workload, time-critical, hazardous environments such as aircraft piloting or performing EVAs. It
is crucial in providing good situational awareness and allowing proper risk assessment and
management.

The Aouda space suit simulator includes a head-up display (HUD) that allows the visualization
of information such as sensor data, procedures, videos or maps. The experiment focuses on the
use of the Aouda HUD to increase situational awareness within the space suit, for risk
assessment and risk management during EVAs.

The basic hypothesis to be tested is whether making trend data available from sensors,
specifically the sensors for carbon dioxide (CO2 ) and temperature within the suit, helps improve
the AA’s perception of risk. This boils down to the research question, “do the CO2 and
temperature readings acquired during an EVA statistically differ if the AA is shown only current
CO2 and temperature readings, vs. trend data for the last few minutes?”
