Video-Hero

Initially the plan was to control something using a guitar hero controller, but I didn't know what or how it would work. With the help of Dave (Cooper), we developed a way to control video through a program using the guitar hero controller to change different settings within the program. 

How it works

What we did was we bought a wireless receiver so that we can receive the signal from the guitar-hero controller. This wireless receiver was plugged into a device called an Arduino and the Arduino device was plugged into my laptop. When I played a note or pressed a button on the guitar-hero controller, the wireless receiver sent all the information through the Arduino and the Arduino sent the information into my laptop. We sent all the information into a program called VPT7, which allowed us to control different things about video depending on our setting. 

VPT7 is a free software where you can upload little video clips and manipulate them by messing with various setting such as mixing two clips together, warping the clips, fading in fading out, cycling between different clips, and even changing between the webcam. Because we could send all the Guitar-hero controller information to the laptop, we were able to manipulate the videos using the guitar-hero controller. This required a little bit of programming to make sure that pressing button 1 on the controller would do something different than pressing button 2 etc. 

We ended up using the whammy bar on the controller to control the fade in of the video, so pressing the whammy all the way down will fade the video all the way in. You could also control the blend of 2 clips by holding down the green button and fading the two clips together using the whammy bar. We also made it so that holding down the blue button and using the whammy cycles through the clips, so we could change what the audience was seeing on screen. 

I was able to upload my own clips of my choice so I had about 5 different clips of cool nature shots that I really enjoyed, along with the 5 default clips that come with VPT7. However, I found that I could only cycle through the first 5 clips that showed up within the program (I found this out too late), so while doing the performance I couldn't show all the nature clips I had gathered. 

Overall the instrument build worked pretty well. There was a bit of a problem with my clips and not being able to cycle through them all but apart from that it worked pretty smoothly thanks to the help of Dave.
