Luc will be our focus of the project. We want to especially focus on the love for technology of this person and provide a fun interaction as the person operates the machine.

analysis:
The dog itself is actually in the background of the project. The machine is controlled entirely by the person. The dog only eats the cookie after it comes out of the machine. The machine must be well-set so that the dog can not destroy it.

Film behavior:
In this short fragment you can see how Luc is operating the current machine. The operation of this machine is ideal for him. He can easily pull the lever backwards with the little finger of his right hand.

Dynamic demands

Personal factors

Transparant so you can see the mechanism
Nice interaction by launching the cookie
Right hand pulling

Product related factors

Compact ( mounted on a specific place on the wheelchair )
At least 13 cookies
Different sizesof cookies

Factors related to the environment of the users

No possibility the cookie end under a wheel

Prototype 10

Practical

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.

Type of weelchair

After contacting Mr. De Wilde by telephone we made an appointment on Friday February 21, along with another group that works with him.

There has also been some exchange of information such as the address and what type of wheelchair he uses. The type is the Permobil m400, a six-wheeled wheelchair with center drive.
