The chairs in the Usability Desing And Testing Classroom are always giving students problems because their legs are out very far that they block students and hit other chairs. Even though, the chairs are comfortable when sitting on them, when trying to move the wheels of the legs bump into other wheels and cause them to jam up and stop. These chairs were not meant to be close to each other and are not usable for being close to each other in a classroom.

The chairs fail our conceptual model of an everyday classroom chair. A conceptual model shows consistency and a coherent system image of a chair in a traditional classroom. A solution would be taking out these chairs and replacing them with four leg chairs instead of five. The five leg chairs could perhaps be used in a one desk person in an area where there is enough space for the chairs to move. A four leg chair would help keep people from blocking and hitting each other every time they move or want to sit down. 

At the Lebanon Valley College, Vickroy Residence Hall dorms have normal size closets. But the closets have a wall blocking half of the closet and allowing a very small space for residence to occupy. I noticed this problem right away because in my dorm, I don't have more space and room for my closet. Why would the residence from Vickroy have to deal with less space? I couldn't find the answer of this question, that is why I think it was a bad design and the wall was not usable.

As you can see in the picture, the closet door is very small and the wall to the right is blocking half of the closet. This design fails mostly the conceptual model of a closet because the closet does not provide a coherent system image of how a closet should look like. In fact, the wall has no purpose for being built and so I believe that the wall fails all of the seven principles of design.

A solution to fixing this bad design would be eliminating the wall to the right, as well as the wall at the top. The top wall is also blocking space from reaching the top shelf. With this simple solution, the residence of Vicroy would have more space in their dorm and easy way to get things in and out of the closet.
