Using a Tablet Computer in Space
 
Oct 31, 2015:  When the Space Age began, there was no such thing as a
"graphical user interface."  Astronauts interacted with their electronics
using only knobs and toggle switches. It was a different time.
 
Fast forward to 2015.
 
The knobs and switches of the 1950s have been replaced by a glass cockpit,
where the majority of commanding is done through software controls.
Old-fashioned twisting and flipping may soon be replaced by a complex
combination of taps, swipes, and finger-tip swirls.

The Fine Motor Skills experiment on the station is looking at how
long-duration microgravity effects fine motor task performance.
 
"Many tasks performed inside a modern spacecraft will involve fine motor
skills such as typing or interacting with a computer touchscreen," says
Kritina Holden, Principal Investigator for the Fine Motor Skills experiment
now underway on the International Space Station. "In the future, astronauts
will use portable computers for many tasks, including maintenance, training,
medical treatment, science, time lining, and scheduling."
 
It is well known that microgravity can have a detrimental effect on the human
body-muscles atrophy, bones weaken, and the immune system doesn't function
properly. Are fine motor skills affected as well?
 
The Fine Motor Skills experiment aims to find out.
 
"We really haven't seen problems, but this type of performance hasn't really
been measured systematically in space," says Holden, who works for Lockheed
Martin in Houston, Texas. "Some experiments have shown that tasks take longer
in microgravity than on the ground, but no study has yet looked at the types
of tests that are included in this investigation."
 
The Fine Motor Skills experiment studies the effects of long-duration
microgravity on the type of fine motor task performance required to interact
with computer-based devices such as tablet computers with touchscreens.
Crewmembers will complete four types of tasks on an iPad: pointing, dragging,
shape tracing, and pinch-rotate.
 
"Our real concern is making sure that future crewmembers can use their
computer-based devices with accuracy onboard and on a planetary surface after
a long voyage, for example to Mars."
 
Imagine what might happen if faulty finger work prevented an astronaut from
accurately checking the life-support system on a future spacecraft?
 
"If we find performance deficits in this long-duration study, we may need to
develop some exercises or practice tasks to keep fine motor accuracy high,"
explains Holden.
 
This experiment could also benefit people on Earth. Holden believes that if
the Fine Motor Skills test battery works well for measuring astronaut
performance in space, it might also be a great tool for measuring performance
back home. For example, it could be used to see how much fine motor
performance a Parkinson's or brain injury patient has lost compared to a
healthy person.
 
"It may also be that one or more of these tasks, if performed frequently,
could serve as a fine motor rehabilitation tool. The team was recently
contacted by a university occupational therapy department interested in
working together to develop some of these ideas."
