Gesture Velocity
A gesture “velocity” is calculated to represent the speed of the gesture. This is done by measuring the time from when
the user first presses the screen until the user releases. The following simplified velocities are supported and transferred
to the master in the custom event message:
1.
Fast
2.
Normal
3.
Slow
A precise velocity is sent in the custom event message which represents the velocity in terms of pixels per second for
slides and circles. For a double tap, this value is the total time in milliseconds from the first press to the second release.
Gesture Prioritization
It is important to prioritize the operation of the presses, moves and releases of the user to avoid confusion over what the
user intended. The following process is used to determine what the user meant whenever a gesture operation is defined
globally or for this page.
Gesture VNC/Mouse Support
Gestures are recognized whether or not the user is using a finger or stylus on the panel's screen overlay, a mouse on a
VNC connection, or a mouse connected to the local USB port on the panel.
Gesture Custom Event
Whenever a gesture is recognized and processed a custom event is also sent to the master. The following values describe
this event:
CUSTOM_EVENT ADDRESS is 1
CUSTOM_EVENT EVENTID is 600
Custom.Value1 is the gesture number
Custom.Value2 is the simplified gesture velocity
Custom.Value3 is the precise gesture velocity
Gesture numbers are:
Gesture Prioritization
The user presses outside of a button or
slider and moves before releasing. The firmware will always try to recognize a gesture as long as the
user moves at least 20 pixels before the release occurs.
The user presses inside of a slider and
moves before releasing. This will always be processed as a slider operation and no attempt
will be made to recognize a gesture.
The user presses inside of a joystick
button and moves before releasing. This will always be processed as a joystick operation and no
attempt will be made to recognize a gesture.
The user moves a movable popup page. This will always be processed as a popup page move and not a
gesture.
The user presses on a button and then
moves. In this case, the press will not be sent for the first 0.15 second. If
the user has moved at least 60 pixels by this time, then a button
press/release will not be processed, but this will be processed as a
gesture. At 0.15 second, the button press is processed and once
the user releases, the release is processed and no gesture
recognition is attempted. To be clear, it is not necessary for the
user to move off of a button to be considered a gesture, but to
move at least 60 pixels in that first 0.15 of a second.
The user double taps on a button or
slider. This will not be recognized as a gesture. This would be considered
two quick press/release operations on the button or slider.
The user double taps outside of a button
or slider. This will be registered as a gesture.
