Mental Workload and Performance Experiment (15-IML-1)
Research Area:
Behavior and performance
Human factors
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Whether on Earth or in space, people tend to work more productively in settings designed for efficiency and comfort. Because well-designed accommodations enhance performance and contribute to congenial relationships among coworkers, the living and working areas of spacecraft used during long-term missions assume particular importance. Also, the complexity of future Space Stations require crewmembers to be capable of supervising the on board electronic logistics. It is necessary to design workstations with efficient computer display formats and input devices.

To optimize the setting for interactions between astronauts and on board computer control systems were the main objective of the Mental Workload and Performance Experiment (MWPE). The experiment focused on motor and cognitive skills associated with such interactions, and designed to understand the demands placed on the astronaut’s mental and physical capabilities during space flight and particularly while operating graphic input devices such as cursor keys, joysticks, and trackballs.
