Participants must be 18 or older.
Face the camera with your whole face clearly visible, even lighting, and no filters. Upload a photo or take one with your device camera if that option is available.
Hand length instructions: Keep your hand open and flat, with fingers straight and together. Measure in a straight line from the wrist crease at the base of your palm—the crease closest to your hand—to the tip of your middle finger. Measure to your fingertip, not to the end of a long nail. Choose the hand you measured and use the same unit for both measurements.
Circumference at band position instructions: Use the same arm as the hand selected above. Find the small bony point on the little-finger side of your wrist (the ulnar styloid). Measure 3 cm (about 1.2 inches) from this point toward your elbow—just a little below the wrist bone. At that position, wrap a flexible measuring tape once around your forearm. Keep it level and snug against bare skin, without squeezing. Enter the distance all the way around in your selected unit. The illustration is a placement guide, not a ruler.

During this paid, in-person wearable data collection session, you will wear a wristband and gloves and complete guided hand and computer tasks. The equipment will collect EMG (electromyography) data: electrical signals produced by your muscles. By checking the box and signing below, you agree to this EMG data collection during your session. You may ask questions or request a pause or stop to recording before or during the session. Pay is $20 per hour. Questions about the session or EMG collection? Email
