Working prototype — not yet miniaturized
A compact wearable to control a computer with finger micro-gestures, discreetly and privately, without relying on voice or a touchscreen. Since February 2025, I've been developing it consistently as a full input system for any device that accepts keyboard and mouse. Glasses and XR are an obvious use case, but the goal is broader: portable interaction for computers where the screen may be far away, on your glasses, or may not even exist.
The challenge
The industry is actively pushing for new, quieter, and more portable forms of interaction. Voice solves a lot, but it doesn't always fit due to privacy, context, or precision. When you need fine control — navigating, selecting, moving a cursor, or typing — there's still no truly comfortable solution for everyday use.
The idea
A small set of natural, discreet gestures, expressive enough to control a full system and simple enough to learn without friction.
How it works
I integrated an IMU (gyroscope and accelerometer) and a capacitive sensor to interpret gestures and distinguish actions like cursor movement, click, and scroll. The device sits on the thumbnail and connects via Bluetooth Low Energy as a standard peripheral.
What I've built
I've developed the system end-to-end, including hardware prototypes, firmware, and host software. Today it already works as a keyboard and mouse, with interaction modes for gesture control, air cursor, click, scroll, and system commands like music and volume control. I've also built a predictive text input engine that runs on the host and a validation app to test real flows and speed up iteration.
Demo
In September 2025, I conducted private demos in Silicon Valley, presenting the project to technical profiles at companies like Google, Neuralink, Intel, and Logitech. That line of work led to a patent application.
Current status
It currently works on macOS as a Bluetooth keyboard and mouse, with several operating modes. The focus is on continuing to refine the experience for real-world use: consistency, ease of learning, and speed in everyday tasks.
