- This example demonstrates a couple features of the TouchNavigation - control. The TouchNavigation control controls most map dragging, - movement, zooming, etc, optimized for mobile devices. + This example demonstates what OpenLayers provides for map + navigation on mobile. +
+ ++ The TouchNavigation control allows to pan the map with touch + gestures on the screen – "touchstart", "touchmove", + "touchend" sequences. It also allows to zoom in with double taps, + and to zoom out with two-finger single taps. The latter is only + available on devices supporting multi-touch. Note that in most + devices Android doesn't support multi-touch in the browser. +
+ ++ The ZoomPanel control provides + and - buttons for zooming in and + out. These buttons should work on any device, and the zoom out + button is especially needed for devices that don't support + multi-touch.
