Do Re Mi

I really enjoyed the outcome from before and thought it was very creative. The refinements you're making with using major musical scales for learning purposes is a great idea. Even someone who is tone deaf like me could comprehend and recognize these differences, whereas I had trouble differentiating between different ukulele chords. It is also better for teaching children because it boils the idea down to easily digestible musical building blocks. I'd suggest looking into using a Kinect or building a physical device with buttons (or something of the like) to gather input and automate the process so it's a streamlined, integrated experience rather than manually doing such things. I'd also suggest trying to avoid the "learning without realizing it" and more embrace the learning aspect. Kids are sharper than most people give them credit for, and they often realize when a game is supposed to be educational vs not educational. I'd also look into educational video games to get some ideas. I look forward to seeing the finished product!

I like this project very much and it will be meaningful for you to “make it a somewhat educational experience” for children. The idea to extend the board to the floor is very appropriate and will make the game more engaging; but I guess you need to find a good place to set the projector, or work with it a bit to reach the ideal effect of projection that you expect. Also, maybe a recorded video about how to interact with the game can be added aside as instructions of the game. As to using the major musical scale, I think people’s familiarity with it will make the game more approachable; however, you might want to develop several modes (ie. different difficulty levels) for the game as older children might have already memorized the scales very well and would like to play a more challenged version :)

P.S. A more technologically-advanced idea (in my opinion) would be instead of having the sound first, the installation will work in a way (much like a musical instrument) that when a child stand on a dot of certain color, a corresponding note from the major scale will be played. Thus, when a lot of children are involved, they can work together to create some melodies. Even when there is only one child, he/she can still have a lot of fun with it by moving around and stepping or touching multiple dots at the same time or consecutively.
(similar idea to 21 swing --https://vimeo.com/40980676, but with colorful dots~)

This is a great educational goal for an artistic project. The ukulele is also an unconventional instrument to use to attempt to teach the topic. Projection mapping seems like a technology that will grab a child's attention and foster an unprecedented appreciated for both tech and the instrument and learning about music while playing music.
