With that in mind, we considered using pressure sensors for translating to the digital space in the working prototype. Each person in the photo would have a pressure sensor behind the picture. When pressure is applied/the physical photo is scratched, the screen would reveal the photo without the person corresponding with the pressure sensor being activated. We briefly tested some pressure sensors with some sample code, and discovered that it's difficult to accurately simulate onscreen the process of scratching, since the code merely switches between the scratched photo and the original when the sensor is triggered. This idea was quickly abandoned, since creating realistic representations of the scratching experience using pressure sensors was time-consuming and its complexity exceeds the timeline of this project.
