(winter show documentation coming)
It’s very exciting to see our installation comes to life since the mini model that we made weeks earlier. To recap, the project is a interactive storytelling installation that consists of several door-sized frames. Each frame “contains” music, visualization, and a small paragraph from a poem written by my partner about death and rebirth. As a participant go through each frame, the sound and visualization assigned to the frame will be triggered.
After my partner’s final presentation last Tuesday and user testing on Wednesday, we decided to change our trigger system, photosensors and laser diodes, to ultrasonic sensors. The problems with our previous triggering system was that it was very difficult to aim laser to the tiny photosensors, and any slight change or movement of the structure will effect the position of the laser, thus resulting in flickering reading of data from the photosensors.
Here’s the code for setting up the ultrasonic triggering system:
Also after the user testing, we have been thinking about how to stop the participant at each frame. We thought about sending a signal for stop by adding a speaker sound every time the participant passes the frame. We also programmed the LED light to blink every time the participant passes one frame.
From this project, we learned a lot about setting up serial communications between two applications, voltage relay using transistors, testing different sensors for desire result, and so on. What we’ve also learned from this project, besides the physical computing part, is that often space is a limitation and factors to consider when it comes to project like this. Something more detachable or easier to transform would be nice to consider next time when doing project like this. It has been a lot of trials and errors, but in return, I think we got a lot out of this project.
