11.11 Grip Switch Triggers
11.0 COVVI Go App
Swipe left to choose the Grip Switch Triggers to
switch between the grips and tables. All triggers
are shown on the left, all actions are shown on
the right. Any trigger that has been assigned has
a tick in the orange circle to the left of its name.
Whichever trigger is highlighted in grey is the one
you are assigning, whichever action highlighted in
orange is the action you are assigning it to. Any
trigger can be assigned to any action, you can
only assign a grip switch trigger once, but you
can assign the same action to multiple grip switch
triggers. If you are unsure of what a particular
trigger or action does, click on it and a box
appears at the bottom of the screen explaining it.
The available Grip Switch Triggers are:
Open/Open -
An Open/Open signal is an open signal to fully open the hand followed by another open signal.
The second open signal must be sent before the Open/Open time.
Long Hold Open - A Long Hold Open signal is an open signal maintained. The hand can be closed, partially
closed or fully open. The signal must be maintained for the Long Hold Open time once the hand is fully open.
Co-Contraction - Co-contraction is when both inputs cross the Co-contraction thresholds within an amount of
time from the On threshold being surpassed. The first input to cross the On threshold initiates the Co-contraction
time (a timer customisable by the user) and if both inputs cross their Co-contraction thresholds before the
Co-contraction time there will be a successful Co-contraction trigger. In the Input Graph the Co-contraction
thresholds must be higher than the On thresholds. Co-contraction only works when the hand is fully open.
Co-contraction can be assigned to any action, however, we would recommend that it is mapped to switching
between devices, for example, an elbow to a wrist.
