No Touchy

No Touchy was a product of COVID. With the disease spreading, we decided to create a simple application for the Apple Watch to help notify people when they reached for their face. We also included some metrics for the previous day, and some voice integration to speak to the user during calibration. Ultimately we were unable to publish the application to the app store due to time constraints, but the core functionality was essentially built out.

Software

• Built with Swift + SwiftUI

The software leveraged accelerometer data to attempt to identify when the user was motioning toward their face. This required marking the application as a "workout" tool, to expose the requisite app permissions. The app included a simple training method that established a rough bounding box of ranges where the user appeared to be touching their face. This method, while simple, proved to be largely effective. Given that we had to balance the computational complexity of the detection with the strict requirements from Apple to hit power consumption targets, we were ok with the potential for false negatives.
