Prototype 13

Prototype based on Prototype 12

Changes since 12:
- Adding rubber band to retract the spoon and 'reset' the movement
- Changing of positions and dimensions to place the spoon better
- Adding nut in the pulling cord to stop the bar from bumping into the head
- Putting the spoon on a rotatable axis, bounded with a rubberband to scoop food better
- Putting the whole system on a plate, so it would fit on Brenda's table

Personal test (6/04/2016)

After this test, it was ready for Brenda

Brenda's test (7/04/2016)

Expected positive:
- Fits on the table

Unexpected positive:
- Tiene likes the system ("With this idea we could help all the children here who can't eat on themselves")

Expected negative:
- Scooping food would be dificult
- Brenda might not like it (hopefully she does)
- She doesn't understand what happens (she doesn't have the cognitive knowledge)
- She can't choose which food she scoops up

Unexpected negative:
- Brenda didn't understand it
- Brenda didn't like it

Score:

Brenda/ Tiene gave us a score of 7 /10

Tiene really liked the effort that the prototype has taken, but Brenda doesn't understand the system. Now we know all types of external systems won't help (the armswing, prototype 7 and this prototype). Tine says we need to look more for something to support her ellbow and doesn't take away her level of independence by making external structures who grab the food for Brenda.
