Continuing to discuss and think about the project, we decided to go back in some decisions and think more about our project, trying to give more context to the concept and problem.
In the brainstorming, Will came with the idea of blocking the image of the projector and this way we could project the image on the door of the elevator. This was a turning point in our project that allowed us to think to redefine our project.
Having the video projection placed on the elevator door itself in real-time, we decided to create a pre visualization of how crowded the elevator could potentially be. We also decided to create a hand crank that invites the viewer to move the graphical presentation of their future scenario up and down accordingly, creating a visual representation of the action of the elevator itself.
First we started by creating a cardboard prototype of the blocker. Sunghun created a system using a proximity sensor that senses when the door of the elevator opens and then, using a servo motor, makes the blocker moves down in order to block the light of the projector
I worked in the prototype of the crank. We made a small/scale model and decided to use a multi-turn potentiometer to make the crank move physically and also to make the image moves up and down. Will was working in the programming of the image analysis and also getting the data from the potentiometer.
Here some images of the first set up of the installation:
We had a lot of implementation issues that had to be resolved and in the first attempt to set up the installation we observe that:
It's was important the localization of the projector and that it had to be set up vertical. Also the video image had to be clipped because the projection area is bigger that the elevator door
Another question was where to put the crank because we didn't wanted to be in front of the image that is projected on the door of the elevator.
Setting up the installation for the first time, made us be aware of some of the problems that we were facing and also we found out that it takes time to set up everything even if in this test we didn't hang the projector in the ceiling and used a web camera .
The next step was starting to build the crank and putting the system working together and of course setting the final installation. Here is some pictures of the final set up that took us almost two days to finish:
