3. Navigation and Controls
Touch Control
The MIZ-21C display includes Touch UI that allows the user to interact with the software application
in some very useful ways. Throughout the software applications various gestures of Touch UI are
enabled depending on the current screen and action. Below are the gestures used with the MIZ21C.
Single Tap on most screens allows you to select a menu item or move features on
the data screen.
Double Tap is used on select screens to provide deeper functionality. For
example, double tapping on the C-Scan display from an array technique will
launch a menu with display options for the C-Scan.
Pinch and Zoom provides additional features for interacting directly with the
screen image. For example, pinch and zoom on the 2D calibration Lissajous
screen can be used to adjust the display scale.
Touch control can be disabled by selecting the Tools menu and navigating to
the Touch Screen preference menu.
