Hold gestures merely denote "there are fingers on the touchpad but they are not moving". As touchpad touches are generally fully abstracted, a client cannot currently know when a user is interacting with the touchpad without moving - no motion events will be sent in this case. The two use-cases here are: - hold-to-interact: where a hold gesture is active for some time a menu could pop up, or some object is selected, etc. - hold-to-cancel: where e.g. kinetic scrolling is currently active, the start of a hold gesture can be used to stop the scroll Since hold gestures by definition do not have movement, there is no need for an "update" stage in the gesture.
