Vex- Your hand is the controller

Most game controllers are built on an assumption nobody questions anymore: you have two free hands.

That assumption breaks down more often than it should for streamers holding a mic or a second device, for people demoing on a crowded booth table, for anyone with limited mobility or the use of only one hand, and even for regular players during long sessions where sustained two-hand gripping is a known contributor to hand and wrist strain. Clinical and ergonomics research on controller use consistently points to the same culprits: prolonged static muscle contraction, repetitive wrist motion, and grips that force the hand into unnatural positions — all of which compound the longer a session runs.

Vex removes the two-hand requirement without removing the input depth.

One hand, full control finger-contact points, wrist motion, and an onboard analog stick are fused into a single wearable, so the other hand stays free for a mic, a drink, a second screen, or simply rest.
Motion replaces reach instead of stretching a thumb across a large controller face, wrist tilt (read by an onboard IMU) handles what would normally take a second stick, cutting down on the repetitive micro-movements that drive fatigue over long sessions.
Combinations replace clutter  rather than adding more physical buttons, finger states combine into distinct inputs, so complexity lives in software, not in a bigger, heavier shell.
Accessible by design, not as an afterthought  a single-hand form factor isn't just a novelty; it's a legitimate accessibility path for players who can't comfortably operate a two-hand controller at all.

Vex isn't trying to replace a full controller for every genre. It's solving a specific, real gap: when you don't have two hands to give a game, you shouldn't have to give up control.
