| value | Event data for recognition gesture. |
Event that fires when the state of a recognition gesture changes.
The platform recognizes hand gestures by tracking the position of either or both hands that are visible to the device. It sees hands when they are in either the ready state (back of the hand facing you with index finger up) or the pressed state (back of the hand facing you with the index finger down). When hands are in other poses, they will be ignored.
