Three-Finger Pinch (Abducted)

Used to pinch medium objects or discs, such as phones, bottle caps, glue sticks. To protect your bionic hand, avoid pressing fingers forcefully.

Two-Finger Pinch (Adducted)

Used to hold strip-shaped objects like cigarettes, or represent "Victory" and number 2. To protect your bionic hand, avoid clamping heavy objects.

Support-Pinch (Thumb Adducted)

Used for supporting bowls, plates, etc. Represents the number 4.

Two-Finger Pinch (Abducted)

Used to hold strip-shaped objects like cigarettes. To protect your bionic hand, avoid clamping heavy objects.

Index Finger Flick

Uses a motor and torsion spring to flick the index finger outward. To protect your bionic hand, it is recommended not to use this gesture frequently.

Two-Finger Pinch (Abducted)

Used to pinch objects of smaller size and weight, representing "OK". To protect your bionic hand, avoid hooking heavy objects with a single finger.

Middle Finger Flick

Uses a motor and torsion spring to flick the middle finger outward. To protect your bionic hand, it is recommended not to use this gesture frequently.

Mouse-Grip Gesture

When this gesture is selected, the bionic hand forms an enclosure around the mouse.

Bunny Ears Gesture

Allows the user to showcase their personality.

Five-Finger Open

Used to hold objects flat and represent the number 5. To protect your bionic hand, avoid supporting overly heavy objects
