Basics

A Silent Speech Interface Designed with Human-AI Teaming In Mind
- Essentially you could search any connected database with the ease of a Voice Assistant without being that guy talking on their Bluetooth Earpiece in a room circa Mid 2000's; you get the picture
It also has a built in Bone Conduction Earpiece so you can get silent audio feedback

Potential Improvements

Integration into a pair of headphones akin to those with an integrated microphone
- Would have stereo sound, and look less odd (Also higher sound quality than Bone Conduction)
Open Source Hardware and Software
- That way no-one can essentially eavesdrop on your inner thoughts to an extent
Bluetooth connection (preferably multi-device) so it can be used with a Smartphone , Smart Watch , or PC as a speech input / sound out, rather than just as a standalone device
- Could improve the devices SWAP stats
The other direction to go would be REJECT AESTHETICS! and have an EEJ Cap + AlterEgo + Project North Star (With Eye Tracking, SLAM Module, and Hand Tracking for all of that sweet sweet data and easy access to the outputs of the computer
Having the Electrodes Mounted in some sort of Hard Hat / Bicycle Helmet Strap etc would be an interesting possibility
