What if a computer didn't live in your pocket or on your desk, but rested behind your ear?
The Pen is our attempt to rethink the form factor of personal computing. It doesn't glow, vibrate, or demand your attention. Instead, it sits out of the way, ready when you need it, and invisible when you don't.
We wanted to build something that feels less like a device and more like an accessory. Something you'd wear because it fits your style, not a fancy gadget.
It's lightweight and discrete. A small computer you forget about until you speak.
Here are some of the early prototypes:

After achieving a functional prototype, we continued to build on top of what we had. We focused on understanding how people experience wearing and using a device like this.
After adding a few more components and making some refinements, we conducted a small study to evaluate user perception and establish interaction design takeaways for the earable form factor. This work led to a follow-on paper exploring episodic cognitive assistance through the ear-worn interface.
This is all pretty great, but what if your device could sense not just what you see and say, but how your mind responds to the world around you?
We are now studying how we can tap into the electrical signals of the body and mind to derive meaningful markers for interaction, assistance, and understanding the human condition at a deeper level.
With EEG (electroencephalography) and EOG (electrooculography), we can pick up electrical patterns from brain activity and eye movements.
Maybe this will lead to a device that knows when you're focused, tired, or distracted, and can detect a glance or a blink as well as it can hear your voice. That's the goal.
This is still early work, and we're exploring what's possible when wearable computing and sensing become a bigger part of your relationship with your environment.
