MedSystems Interactive Prototype

prototyping, creative coding 
Tools Used: After Effects, Raspberry Pi
Collaborators: Ben Glasser, Flora Zhou

Design Brief:

Create an interactive experiential prototype of part of the MedSystem using the Raspberry Pi and: one switch; at least 1 video (which you must edit); and a projector.

Technology Excerpt:
“MedSystems, operated by sophisticated AI systems, are able to repair nearly any damage short of death or destruction of the brain. MedSystems are designed for use by humans rather than constructs, but can also repair a construct’s organic parts, which consist of cloned human tissue. (Injuries sustained by constructs are normally treated in a repair cubicle, which has specialized tools and equipment to handle the extensive inorganic components.) Self-contained wound packs capable of automatically administering anesthetic and antibiotics and stimulating tissue regeneration and portable emergency medical kits with built-in instructional feeds are also available.”


We began this project by dicussing the aesthetics of our interactive system and how it would be displayed. We wanted to show our MedSystem in a Ready to Scan state, interrupted by a patient being placed within the system, then show the system scanning and healing a patient. Blade Runner’s retrofuturist scanning aesthetics heavily influenced our design. 

We began by testing the projector and designing the graphics for the videos in After Effects. 

Once we had our videos ready as two videos, we added the sound from our previous audio prototypes. We uploaded them to the Raspberry Pi and set Ready to Scan as the default video to play on a loop. Then, we wired the Raspberry Pi using two circuit-activating sensors made with aluminum foil. One sensor was taped to the wall, and the other was taped to the user’s back. Upon touching, the two sensors allowed the circuit to turn on and the Ready to Scan video was interrupted by the Scanning and Procedure in Progress video.


Though this prototying took some fixing along the way due to its interactive nature, we were able to get the result we wanted in the end. Ideally, we would have displayed the prototype with a patient laying down in the MedSystem, but because of the projector limitations we had to display our system on the wall. I’d like to continue iterations of this prototype with different types of projectors that may allow the patient to lay down in the MedSystem, with the prototype projected on top of their body.
