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.

Opposed Grips

COVVI Grip Patterns - Precision Grip

Precision Grip (Open & Close)

These grips use the thumb and index finger to hold small objects. The thumb moves to a fixed position and the index finger clamps the object against the thumb, which facilitates 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 closed 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 spray bottles or a power drill. 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. The index finger can then flex to work the trigger.

COVVI Grip Patterns - Power Grip

Power Grip

The four fingers flex towards the palm around an object with the thumb completing the grip by locking over the first two fingers. This is a stable grip for when holding heavier items, but it is also great for daily and manual tasks such as carrying bags, pushing a shopping trolley, or mowing the lawn.

COVVI Grip Patterns - Glove Grip

Glove Grip

This grip is to aid dressing and undressing. The fingers flex slightly and the thumb flexes in towards the palm. This grip makes the hand as slim as possible to make it easier to put on clothing, for example, pulling a jacket sleeve onto your arm.

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 fourth 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 - Precision Grip

Tripod Grip

This grip uses the thumb and first two fingers to hold objects. The thumb moves to a fixed 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 - Key/Card Grip

Key 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 first finger. This grip is for holding thin objects like credit cards or keys and can be used in domestic tasks such as carrying plates.

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, point and use a smartphone.

COVVI Grip Patterns - Column Grip

Column Grip

This grip is ideal for pushing objects or pressing large buttons and switches. 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 - Mouse Grip

Mouse Grip

This grip is specifically designed for using a mouse. The fourth finger and thumb grip the mouse while the index finger is used to click the mouse button.

COVVI Grip Patterns - Relaxed Grip
