From the project

Source code repository for ENGAGE: Battery-Free Game Boy

This is the official public repository for ENGAGE: the battery-free gaming console.

Battery-free devices can make phone calls, facilitate machine learning, or even track eyes, but immersive interactive experience without batteries has not been explored so far. In this project we focus on this ignored part of the battery-free device ecosystem. We explore how reactive and user-centric applications, mobile gaming in particular, can also be battery-free.
