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.
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.
This grip uses the thumb and first two fingers to hold objects. The thumb and four fingers move simultaneously, but if uninterrupted, finger 3 and 4 will flex in towards the palm and fingers 1 and 2 will clamp against the tip of the thumb.
Active finger tracking ensures a reliable and stable grip.
This grip is for the use of trigger operated objects such as hairdryers, spray bottles, a power drill or electronic garden tools.
When a close signal is sent fingers 2, 3 and 4 will close around an object followed by the thumb to maintain it steady. If the close signal is maintained the index finger will then flex activating the trigger.
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 arm and the fingers. In precision open the thumb moves to a known resting position and the index finger comes to meet the tip of the thumb.
The rest of the fingers remain extended allowing the user to get the hand close to the object. In precision closed, fingers 2, 3 and 4 close first, the thumb moves to the known resting position and then the index finger meets the tip of the thumb. This grip is designed to offer the user better visibility of the object they are picking up.
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!
In response to a close signal all four fingers flex towards the palm around an object with the thumb completing the grip by locking over fingers 1 and 2.
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.
This grip is specifically designed for using a mouse. When a close signal is received, the thumb and little finger move simultaneously to hold the mouse.
Reapplying the close signal will partially flex the index finger to tap the mouse and releasing the close signal will extend the index finger again. Only applying an open signal will fully open the hand again.
This grip is very similar to the finger point grip but has the additional function of an active button press. When the close signal is maintained the index finger partially flexes and when the signal is released the index finger extends.
This allows the user to keep the wrist static and press a button.
Finger Point Grip
This grip enables the user to press buttons, ring a doorbell, use a smartphone, or point out directions.
Fingers 2, 3 and 4 flex in towards the palm, the thumb closes to a fully flexed position and the index finger remains extended.
This grip is ideal for a variety of tasks such as pressing buttons, calling lifts, or turning light switches on and off.
When a close signal is sent, the thumb flexes to a fully closed position, then all four fingers close simultaneously over the thumb.
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.
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.
In response to a close signal all four fingers partially flex and the thumb closes to meet the distal section of the index finger.
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.
