Paper Prototyping

Our class team tests the interface of our blood testing kiosk. Instead of designing a live, touchscreen interface, we used paper to quickly test if our concept was going to work. Here are the results from four random subjects.

Interesting idea, though it seems to have overlooked some issues: why not ask for a language preference? Why not ask the gender of the user? Why not verify the user has an index finger, or right hand for that matter? No instructions regarding the preparation for the needle?
I might also suggest some privacy notification for those using a credit/debit card: the test results could be traced back to the person if the credit card information was stolen from the machine/network.
Also, the needle might be clean but the area where the hand is placed may not be. A previous user may drip blood on that surface - how would that get cleaned? Is there a UV sanitizer that is employed under the cover?

wow! that is really good! thank you for the video.

U MISSED A LOT:
I wouldn't use this machine. Yes it is fast and convenient. But how can you guarantee that machine had really sanitized itself? Someone may have been testing blood for STD before? Maybe machine was stuck and needle didn't clean, maybe sanitizing liquid is same. Etc. I would only go to solution where I would "attach myself sterile needle" on the machine. or smth. The least I would need explanation of how the sterilization is done.

realy after paymant we not see screen. And what hapned if user remove hand before message)) no information about " pls don`t remove your hand before GRENN ligth

[@dimkir100]

Next: u just tested linear operation (when every step of user is successful). What if user is removing hand when the countdown happens?
What if user has no index finger? (or his indexfinger is in cast or too sensitive for needles)?
What if test fails several times? Am i supposed to put needle into my fingers for hours? What if person walks away from the machine and never gets back? What if test eventually cannot be performed, will my money be returned? What if i am afraid of blood and faint?

[@dimkir100]

What if I need more specific requirement for the test (there can be probably around 50-60 different "blood parameter" tests performed on blood (simpliest are sugar, or eritrocits). What if I am "advanced user" and need special ones? When performing sugar test, person is not supposed to eat breakfast (or eat few hours before test) so machine should ask/warn him about it.
Users didn't seem to understand idea of paper prototyping. Maybe they should have shown be4 proto of smth familiar? Like ATM?

@lindstormORG No necessarily, in this case I think ensuring the user that the environment is sanitized will make him feel more comfortable and safe.

The user should have to remove their credit card before proceeding to the test because there's a good chance they'd walk off without their card because they'd be so focused on the results print out..
It's a really good idea though..

I felt like the lady could be friendlier. The first user sounded a bit intimidated.

[@adrianshirazi1857]

this is awesome

[@rich1874]

I agree

[@emilylam1781]

this is #cool

10 years later and this technology still hasn't been turned into life
what a shame
