Prototype 10

Dimensions and placement old biscuit machine
The old machine is mounted on a square aluminum profile of 1.5 cm by 1.5 cm with the aid of a screw, which provides clamping.
Current machine is still about 11 cm below the profile. There is also a cover provided so that the cookies do not end up under the wheel of the wheelchair.
Between the handle and the container there is 8 inches of space.

Operation current machine:
Luc pulls a lever and there is a cookie that falls through the tube down. Luc cant see this happen, he just hears it  and sees a happy dog​​.

Ideas and thoughts after first visit

• 13 cookies is for the current dog enough for one day.But Luc gets a new young dog in June, it should probably still learn so it might need more cookies per day
• Luc is very interested in technology, so it would be nice that he can see how the machine works every time he uses them
  => Possibly work in Plexiglas so that everything can be seen
• extra dimension: create fun interaction
• Strong design: lasercutten

First visit to Luc and his assistant dog

Because Luc still lives with his parents and his father have eye problems, Luc prefers not being too busy during the visit. So the agreement is that one person of each group visits Luc in the weekend.

Luc is very enthusiastic about the project. However, his dog is very old and in June Luc gets a new assistance dog. The cookie machine must not be designed for this dog. Because the dog itself should not operate the cookie machine, this is not a problem for the continuation of this project.

Luc and his new weelchair

Luc demands:

• Luc himsel has has to operate the machine, not the dog.
• The machine has to be solid so that the machine doesn't brake when the dog is too interested in the cookie machine.
• The machine mst be designed for the right hand.
• Different cookie formats.
• We cant use electricity from the wheelchair => to expensive wheelchair ( so preferable mechanical system )
• At least a magazine of 13 cookies a day.

Luc wishes

• Preferably a nice interaction (eg cookie is flying in the air)
• new machine positioned in the same place as old machine

The assistance dog is in everything he does well rewarded. Luc cant do this by petting him and thus he gives the dog a cookie every time. And so te cookies should be so thin that the dog is not too getting thick. Luc has a certain brand of cookies and the machine is designed based on the shape of that specific cookie. But unfortunately, the cookies will disappear from the market. As a result, the current machine can not be used anymore.
