The Theremin is a very weird instrument. It doesn’t have a key, or bars, or markers on how you play it. You simply.. move your hands in the air. But the basic mechanics are just distances. The vertical antenna controls the pitch, and the horizontal antenna controls the volume. Move your hand away from the vertical antenna, you get lower pitch and closer moving your hand closer to it generates higher pitch. Move your hand closer to the vertical antenna to get a lower volume, and raise your hand to raise the volume.
Although the basic premise seems simple, what is really unique about it that it is a very sensitive device. Even though your wrist is in the same position, if your fingers are in a different position, the Theremin will emit a different sound. So to play an existing.. sheet music, you will have to replicate the positions of your hand as well as your fingers. It would be easy if there were standardized finger positions as you would play the guitar, but because it’s so free, you have to replay the exact position to get the same note.
I think the way for a musical composition to be accurately played on a Theremin, it at least needs to feed 3D points as instructions to the user.
So the multiple concepts that I have come up with are:
3D projectors/AR goggles
The 3D projectors/AR goggles would display a glove that the user follows and displays clues for next movement to give user instructions at the precise time to reproduce the composition.
like a real life osu game
- Users just need to follow the hand
- Very flexible in deployment
- No physical feedback for the user
Robot arms and fingers
A robot arm and hand that the user wears to guide them and how to move their hands. Like a coach physically moving your hand
- Guaranteed to be very accurate
- Physical feedback to user input
- Very involving to wear
- complicated to create
High definition tactile feedback gloves
A glove with a ring-shaped array of vibration motors around the wrist and every finger. Vibrates in the direction that the hands need to be.
- Physical feedback
- Less involving than a robot arm
- Needs an external sensor to see the glove’s position in 3D space
- The vibration motor must be really responsive for the user to be able to reproduce the composition accurately

This Pugh matrix reveals that the 3D Projectors / AR Goggles are the best solution to pursue now. But this might not tell all of the story. This concept and other concepts can be used together to provide a complete experience, physical feedback with directions for future movements, although the devices that the user needs to wear will increase a lot.
