Congratulations man, well done! Me, I donāt even fully understand the title. It is aiming to ease peopleās use of their new prosthetic arms, is it?
Congratulations! One of those truly impressive achievements!
Congratulations! Way to go!
Congrats!
Well done @JohnAtl !
Now, to which particular app do you ascribe your fantastic success?
Only kidding! 
Wow!
Thanks everyone!
Most people who have upper-extremity limb loss donāt use prostheses. Those who do only do so 50% of the time they could. Weāve all seen the new high-tech Iron Man arms, etc. but the rejection rates remain high, so engineering isnāt solving the problem. My thinking going in was it is the loss of sensory information that has a major effect on prosthesis disuse. Sensory loss as in the inability to feel with a prosthesis, and also sensory loss as in not knowing the motor (muscle) commands that lead to the prosthesisā movements when we are watching someone use a prosthesis.
Thanks @beck for the announcement here, thanks @DrJJWMac for help with LaTeX, and thanks everyone for the kudos

It could be up to a year, as it will be embargoed until we publish the rest of the work.
To understand why people hate using them.
One of my participants, a quadruple amputee, drove in without her arm prostheses on.Carried them in in a bag, put them on for my study, then immediately took them off to fill out some paperwork.
