Grip Patterns

Grabbing Hold of Life

The Nexus 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.

There are a total of 14 grip patterns in total. Opposed grips are defined by the thumb being in opposition to the fingers, while Non-Opposed grips position the thumb parallel with the fingers on the hand.

Opposed Grips

COVVI Grip Patterns - Precision Grip

Precision Grip (Open & Close)

These two grips use the thumb and index finger to give a reliable and fast method of picking up, holding and using small objects with precision which aids the user as it does not require simultaneous movement of the hand and the fingers. In ‘Precision – Open’, the rest of the fingers are extended and in ‘Precision – Close’ the fingers are flexed in towards the palm.

COVVI Grip Patterns - Trigger Grip

Trigger Grip

This grip is for the use of trigger operated objects such as hairdryers, spray bottles or electronic garden tools. It features an extended index finger used to activate a trigger while the rest of the fingers flex in towards the palm around the object and the thumb closes around the object to hold it steady.

COVVI Grip Patterns - Power Grip

Power Grip

This is a stable grip for carrying bags and suitcases and holding heavier items, but it is also useful for other tasks such as pushing the trolley at the supermarket or mowing the lawn.

The four fingers flex towards the palm around an object with the thumb completing the grip by locking over the first two fingers.

COVVI Grip Patterns - Glove Grip

Glove Grip

This grip is to aid dressing and undressing as it helps the hand slide through sleeves without catching.

The fingers flex slightly and the thumb flexes in towards the palm to put the hand in the slimmest position possible.

COVVI Grip Patterns - Rock Grip

Rock Grip

This grip is not a functional grip. It enables the user to display their inner Rockstar! The index and little finger remain extended, while the middle two fingers flex in towards the palm with the thumb closing over them to give the rock gesture. Rock on!

COVVI Grip Patterns - Tripod Grip

Tripod Grip

This grip uses the thumb and first two fingers to hold objects. The thumb moves to a fixed opposed position and the first and second fingers clamp the object against the thumb. Active finger tracking ensures a reliable and stable grip.

Non-Opposed Grips

COVVI Grip Patterns - Column Grip

Column Grip

This grip is ideal for a variety of tasks such as pressing buttons, calling lifts, or turning light switches on and off. The thumb flexes in towards the palm and the first two fingers close over the thumb.

COVVI Grip Patterns - Phone Grip

Phone Grip

This grip is not a functional grip. It is to imitate holding a phone. The thumb and little finger remain extended and the rest of the fingers flex in towards the palm.

COVVI Grip Patterns - Relaxed Grip

Relaxed Grip

This grip provides a natural resting position for when the hand is not in use. The hand is open, but the fingers and thumb are slightly flexed.

COVVI Grip Patterns - Mouse Grip

Mouse Grip

This grip is specifically designed for using a mouse.

The thumb and little finger grip the mouse whilst the index finger is used to click the button.

COVVI Grip Patterns - Key/Card Grip

Key/Card Grip

All four fingers partially flex to provide a stable platform and the thumb moves to a non-opposed position against the side of the index finger. This grip is ideal for holding thin objects like keys, credit cards or paper, but it can also be used in domestic tasks such as carrying plates or holding a knife.

COVVI Grip Patterns - Tap Grip

Tap Grip

This grip is very similar to the finger point grip. The only difference is that the index finger moves up and down, which is especially useful for using a keyboard when the flex wrist is locked into 30° extension, as it gives the user the ability to accurately position the fingertip for easy typing.

COVVI Grip Patterns - Finger Point Grip

Finger Point Grip

The index finger remains extended while the rest of the fingers and the thumb flex in towards the palm. This grip enables the user to press buttons, ring a doorbell, use a smartphone, or point out directions.
