Why is a forearm sleeve better than a smartwatch for shared, social moments?

A watch display is private and oriented to its one wearer, so reading it pulls your wrist away from everyone else. The 9-inch forearm canvas faces up and two people can use it at once.

Can I operate the sleeve with gloves on or with my chin?

Yes. The 5 sewn pads respond to a finger, knuckle, opposite wrist, or chin — so gloves, cold hands, or messy hands don't block input the way a bare watch glass does.

How do washing and charging compare to a smartwatch?

Unsnap and slide the sealed 8×32 LED and Bluetooth pod out of the inner pocket, hand-wash the sleeve in cold water, and hang dry; you charge only the small module, not a whole watch puck.

Forearm 8×32 LED & 5-Pad Touch Sleeve vs a 40mm Smartwatch

Swap your wrist-twist for a zero-twist sightline: the $199 Garment GUI LED & Touch Sleeve gives you a 9-inch shared two-player canvas, 5 pads you can tap through gloves or with your chin, and washable slide-out electronics.

Read without a wrist-twist: because the display sits along your forearm, it stays in peripheral vision — and it is a shared canvas two people can use at once.
Gloved, wet, or chin taps: 5 sewn fabric pads answer to a finger, knuckle, opposite wrist, or chin, where a bare capacitive watch glass ignores gloves.
Ready out of the box: ships as one of the 50 built-in modes; the LED + Bluetooth pod slides out in 5 seconds for cold hand-washing.

Why a Private 40mm Watch Glass Cannot Be Shared, Gloved, or Washed

A watch is private and small: reading it means twisting your arm and staring at a 40mm glass you cannot share and must charge on a puck every night.
A 9-inch shared forearm canvas: the matrix faces up, so two people can play a bar game, read a message, or see a status cue together without a twist.
Peer-reviewed roots, shipping hardware: the Oct 2026 NUS Nature paper coined “garment GUI” with a lab-only woven pixel fibre (not for sale); our shipping $199 sleeve uses 5 sewn pads and a removable 8×32 LED pod.

What Each Forearm Pad Does (Pads 1–5)
