How does the sleeve trigger OBS Studio without custom plugins?

It pairs as a standard Bluetooth HID keyboard and sends F13–F16 function hotkeys (or any key combo you set in Sleeve Studio) directly to OBS Studio, Ecamm Live, or vMix.

Will the red tally light spill onto a subject's face during a close-up gimbal shot?

Tap Pad 4 to drop the 8×32 matrix to 15% PWM studio dim mode, or load the 4-pixel inner-wrist tally profile so zero light faces the lens.

Can a podcast producer push silent wrap cues from across the glass?

Yes—keep the Sleeve Studio app open in Chrome in the control room within BLE range to send silent 12-character wrap prompts ('HARD OUT 2M') to the host's wrist.

OBS Studio & Multi-Cam Live Wrist Tally Light on an 8×32 LED Sleeve

Built for gimbal operators, livestreamers, and multi-cam hosts, the Garment GUI LED & Touch Sleeve turns your forearm into a low-latency Bluetooth tally light (PREVIEW green, LIVE CAM 2 red border, MIC MUTED amber) plus one-tap timestamped B-roll markers on Pads 1–5 ($199).

Tally in constant peripheral vision: Live, preview, and muted state stays on your leading forearm even when you pan away or turn to a co-host.
Silent scene macros: Five pads cut cameras, mute your mic, dim the LEDs for dark shoots, and drop B-roll markers without a laptop.
Ships as 1 of 50 modes: Pre-loaded as OBS Tally Light; remap any hotkey in the Sleeve Studio app.

Watch the 8×32 RGB LED matrix and 5 conductive-fabric touch pads running the 50 built-in modes and multi-mode switching on the forearm sleeve. Concept render · simulated 8×32 display · first production run of 500 units.

Why Hot-Shoe Tally Lights Fail Gimbal Operators and Moving Hosts

Hot-shoe lights go dark: A monitor-mounted tally vanishes the moment a gimbal operator pans away or a host turns across the table.
Fingers free for macros: Five silent scene-switching pads sit on the arm already holding the rig.
Peer-reviewed textile 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 conductive-fabric pads and a removable 8×32 LED pod.

What Each Forearm Pad Does (Pads 1–5)

Pad 1 (Elbow)Single tap — Drop timestamped 'GOOD TAKE' marker into NLE / OBS log · LED cue: Flashes cyan MARKER @ 14:22 for 1.5s
