There are three major components to this project:

1. Wearable capture devices. These include semi-custom development boards (with some assembly required) as well as off-the-shelf products like Apple Watch. We would like to develop fully custom open source hardware.

3. Presentation clients. Applications that display information gathered by the system (e.g., transcripts, conversation summaries) and allow interaction with an online assistant. Currently, a mobile app and web app are included.

### Getting started with development boards

Designing an AI wearable involves balancing compute power, sensor capabilities, and connectivity to achieve the desired battery life and form factor. Fortunately, there are many development boards available that make it easy to get started and begin field testing. Below are just a few boards we've experimented with for inspiration.
