I created a wizard-of-oz demonstration using two breadboards. One that I wired with a photon cell, LED, and Particle Photon to simulate the interaction when the family member places the rock to cover the pain (light). Then I wired 9 LEDs to a battery source to represent the other pain (light). For the video demonstration, I rewired the breadboard with 1 LED to the battery source to simulate the patient’s zen garden lighting up. I made the boxes out of foam core to encase the wiring and used clear plastic as the base so the LEDs would shine through to light up the sand.
