Mid-term evaluation of the prototypes so far

We were thinking about using a magnet. This has to be a very strong magnet. We weighed the front of his bike because this is the part he pulls while jumping. The front weighs about 10 kilo's.

We looked at how he places his hand on the handlebar. For us it is important to see where he excercises pressure. As you can see after only a few seconds on the bike, the print of the handlebar is already imprinted in his hand.

Conclusions:

We needed to know a few more things before we could continue prototyping. 

We for example asked if he would like the product to blend in (either with the bike or his arm) or for it to be personal. We thought about using the colors of his favorite football team, which is Anderlecht. He does not really care about the aesthetic. He prioritizes the functionallity. But when possible, he prefers the product to blend in with the bike. 

Sander added a demand to the list of demands. He would like the product to be closed so that it is windproof. When the temperature is lower than 20 degrees, he does not like to bike because the cold wind hurts his hand. He never used gloves and does not want to start using them now.

Sander's hand is really sensitive and therefore he would like to have some sort of cushion or gel.

Sander told us he used to mountainbike before the accident. He likes to ride at the Kluisbos, Muziekbos and in the Ardennen.

For next time it is important that we make prototypes that are more firm so that they can actually be tested. For Sander it is important to feel and experience. 

Prototype 6

Prototype 6

This prototype shows a way to lock the hand onto the handlebar. It will only come of if you folow the profile. While riding the bike it will stay in place.

Testing:

Sander liked the idea but he said that it was going to be difficult to take off.

 

Sander like the idea about this prototype, but as said above, he was worried that it would be too difficult to take off.

Prototype 5

Prototype 5

This prototype solves two problems: how to attach the hand and how to attach the prototype to the handlebar. Inside the sock there is a cushion to make it more confotable.

Testing:

He liked the connection to the handlebar on this prototype. He also liked the cushion. The wooden stick was too long (he needs a direct response) and the sock will come off.

+	–
Connection to the handlebar	Wooden stick too long
Cushion	Sock comes off

 

The reason that he liked this prototype was because of the connection and the cusion. The connection to the handlebar gave him a stable feeling while also allowing an extension of his arm. The wooden stick between the handlebar and the bottom of the sock was too long though. Because of this he felt a little less stable.
