What should OpenAI build as their first hardware device?

My teammates and I sought to answer this question, exploring the hardware × AI landscape, ideating a bunch of concepts, testing them with users, and iterating upon the feedback we received from designers in the industry (we even presented to a designer who worked on the Humane Pin!). Eventually, we landed on an ambient wearable we called Tomo.

Problem

Currently, ChatGPT’s knowledge of you is limited to what you tell it.

Memory in ChatGPT is only capable of being stored as text entries, like: “Christina is a product designer” and “Christina’s lactose intolerant”. It doesn’t have context of what you’re currently doing, and because it’s limited to what you tell it, it’s not as useful as it could be.

Solution

Introducing Tomo: an AI-powered, ambient wearable that acts as ChatGPT's eyes and ears.

With a camera, mic, and pin at the back, you can wear it as a pin or a pendant. Tomo is a wearable that acts as the eyes and ears of ChatGPT. By seeing and hearing what happens in your day, it builds a living memory of your life — powering “Moments”.

Moments

Tomo powers Moments: capturing your everyday in ChatGPT.

Moments is a new atomic unit in ChatGPT, a log of all the events and conversations and solo adventures captured by Tomo. Moments powers up the existing features of ChatGPT like smart suggestions and reminders to be more personalized to the user and to be stickier.

Why? Because the AI that knows you the best is the one that you won't want to switch off of.

The rest of this case study is currently in progress.

Sorry about that ;_; In the meantime, you can view this slide deck to learn more about the project!
