Finally!!
This was quite a journey, with many ups and downs but definitely one that ended in relief and content! The idea of our final project revolved giving our audience a chance to go back to their childhood and just have fun! Anyone that interacts with our project is given the opportunity to just draw whatever their heart desires, and the physical interactivity (because users will draw with their hands) gives it an extra interesting and more immersive experience. We wanted our project to give the user complete freedom, so they users can choose between 5 different brushes and use the color they want to draw using the color selector.
Implementation:
There were mainly two aspects of this project, the processing aspect and the Arduino aspect (and serial communication). This is essentially also how we split the work between us. Fatema essentially took on the challenge of the processing side of things and I took on the challenge of the Arduino side of things and the blog documentations. So Fatema is the one that created the beautiful generative art pieces that played the role of our brushes, and she worked on the fiducial tracking as well (which was a pain! so she did a great job). While I focused on the arduino side of things, wiring up the buttons and slide potentiometer, creating the color gradient and its code on processing, and creating the serial communication between arduino and processing, I also took responsibility of the blog documentation. However, we also found ourselves working together most of the time, Fatema would help me with the arduino when I was stuck and vice versa. So it eventually turned into us working together on most of the aspects of the project rather than individually which worked out great!
lessons learned/how to improve:
This project is one that definitely helped us grow. Naturally it was not a perfect linear growth, hence there is always room for improvement. reflecting on where we can improve is definitely an essential thing to do. After the showcase these are the things we noticed could have been executed better:
- During our presentation to the class on the 13th, a very inconvenient and stupid mistake (we just need to move the location of the project slightly due to lighting issue) caused us to panic and not be able to show the class our project. lesson learned! we should have set up earlier especially since our project was not very straight forward and is prone to spontaneous errors.Luckily it all worked out in the end.
- When it comes to the project itself, we found that we should have included some sort of feedback for when the buttons are pressed, just to let the person know which brush they are using.
- We also learned that sometimes the finer details take even more time and effort than the bigger aspects of the project! and they bring the project together at the end.
IM showcase:
Here are some of the very unique masterpieces that people created on our digital doodle in the showcase. It was so much fun seeing how different people interacted differently with our project!
And here are a few video out of many of people interacting with our project (you can see how people move in the camera on the screen)!!
