Grabbing Hold of Life

The COVVI hand is the most advanced of its kind for the intuitive default grip patterning that it offers in addition to the grip-mapping capabilities that allows the user to input custom-made gesturing into their device with their clinician. Hands are tools people often take for granted, but they are capable of so much!

We at COVVI understand that and want you to get to know each of the grip patterns as if they were your closest companion.

Covvi Grip Patterns - Power Grip

Power Grip

For carrying or grasping where all four fingers flex towards the palm, with thumb locking over the first two. Important for manual tasks and is the most forceful grip, but also most useful when combined with a passive flex wrist (reduces shoulder compensation).

Covvi Grip Patterns - Trigger Grip

Trigger Grip

Similar to the finger point grip, this mode features a flexed first digit enabling use of objects with triggers such as spray bottles and power tools. The rest of the fingers flex in towards the palm of the hand and the thumb holds the object steady.

Covvi Grip Patterns - Key/Card Grip

Key/Card Grip

As indicated by its name this grip is for holding thin objects like credit cards or keys, although it’s also great for domestic tasks like cooking, e.g. carrying plates, using a steak knife. All four fingers partially flex to provide a stable platform and the thumb moves to an unopposed position against the side of the first digit.

Covvi Grip Patterns - Finger Point Grip

Finger Point Grip

Where all fingers and thumb flex to palm apart from the first digit which remains straight. Enables the pressing of buttons and typing on a smartphone keypad, as well as being a socially indicative tool (when giving directions, for example).

Covvi Grip Patterns - Precision Grip

Precision Grip

Allows for the holding of very small objects such as needles, blades of grass, or anything else that requires close inspection with the eye, between first finger and opposed thumb – the rest of the fingers flex in towards the palm.

Covvi Grip Patterns - Pinch Grip

Pinch Grip

This position allows objects to be held solely between fingers and thumb without relying on the palm of the hand. The first and second digits are driven against the thumb which provides a stable grip for medium-sized objects, although the active finger tracking in the hand ensures a reliable grip regardless of object size.
