Prototype 8 & protomorphing

Prototype 8

With this prototype we try to connect the prototype to the handlebar by using a slide system. The hand is attached by a cotton strap. The strap is bigger than the previous one to divide the pressure and also to protect the hand from the cold winds.  

Protomorphing:

We put double sided tape on this prototype so we can change the sort of cushion we use to absorb the shocks.

Testing:

The strap is hard to put on, but easier than the previous prototype.

It would be easier to use one big slide instead of two. It is easy to click in, but difficult to click out. The clicking noise helps. This gives auditory feedback. A slide to the side would be better than a slide to the front.

+	–
Easier than prototype 7	Strap hard to put on
Easy to click in	Difficult to click out
Clicking noise	Should use 1 slide instead of 2

  

Extra questions:

Do you want support for wrist?: no Do you want to be able to change the size of the strap?: yes

Prototype 7

Prototype 7

This prototype is to test the attachement to the hand as well as the attachement to the handlebar. 

Testing:

The strap is hard to open, but gives good support. It does not hurt as long as there is some sort of cushion. The gel feels good, but has to be everywhere. The slide system turns too much.
