You can adjust Views in the Atlas and Quiz modes, or after hitting the "Pause to Explore" button during an interactive animation in the Show mode, using the following actions:
Pan: Swipe three fingertips across the screen to pan in any direction.
Zoom in: Place the tips of your thumb and forefinger on the screen and move them apart to enlarge the structures within the view.
Zoom out: Place the tips of your thumb and forefinger on the screen and move them together, as if you are pinching, to increase the scope of the view.
Center: To center the View on an anatomical structure, tap twice quickly, with one fingertip, on that structure.
Rotate or tilt: Place one fingertip on the screen, then slowly drag your finger in the desired direction to tilt or rotate the model. To change the axis of rotation, tap twice quickly on any area of the model; that area becomes the new axis of rotation.
Background Color: This button at the top of the screen, directly to the left of the Visible Body logo, allows you to toggle between a white or black background for your Views.
