The Concept

OUIS: The Sleeve That Listens When You Touch It The Open Universal Input Sleeve — OUIS — is exactly that. A fabric sleeve embedded with conductive fabric touch sensors that turn the surface of your arm into an input device. Tap a patch of fabric, trigger an action. It's soft, it's wearable, and it works with virtually anything you want to control. The "Open" in OUIS is intentional. This isn't a finished product with one fixed purpose — it's a platform. A starting point. A sleeve-shaped blank canvas that you wire up however your project demands.

The Concept

Conductive fabric is remarkable stuff. It looks and feels like ordinary textile, but it carries electrical signals the way a wire does. Sewn into a sleeve in deliberate patterns, it becomes a series of touch-sensitive zones — each one a button, a trigger, a switch — all built from material soft enough to wear against your skin all day.

OUIS maps those zones to inputs on a microcontroller. From there, the possibilities are genuinely open: trigger sound effects, control LEDs, send keyboard commands, drive a puppet, advance a slide deck. Whatever needs a human touch to activate it, OUIS can be that touch.

It is also one of the most compelling introductions to conductive fabric that exists — because the feedback is immediate. You touch the sleeve, something happens. That cause and effect is deeply satisfying, and it makes the technology feel accessible in a way that breadboards and jumper wires often don't.

Why a Sleeve?

A sleeve is always with you. It moves the way your arm moves. It disappears under a jacket. It doesn't look like technology until it does something extraordinary.

For performers, educators, musicians, and accessibility advocates, that invisibility matters. OUIS lets you keep your hands free and your tech hidden until exactly the moment you need it.

Build It Yourself

Full build instructions - all 12 steps - are available on Instructables, and a complete video walkthrough is on the YouTube channel. Conductive fabric, conductive thread, and everything else you need to build your own OUIS is available here in the Tinker Tailor shop.
