Gestures are performed on the touch screen exactly as they are on a track-pad. The action associated with each gesture can be defined in the gesture settings dialog. To utilize all available gestures you will need to use a multi-touch touch screen that supports up to 5 touches otherwise you will be restricted to the gestures that relate to the number of stylus supported on the touch screen.
A number of videos showing the use of our software have been posted on the web from end uses such as this one here. Mac OS X gesture usage is shown here.
These notes relate to various gesture functions as described:
| Function |
Notes |
| Two finger Tap |
The Two finger Tap invokes a right click which is generated by default under the left stylus. This behaviour can be changed to generate the right click under the right most stylus. A time threshold is also configurable to specify the time in which a two finger tap can occur. |
| Press and Tap |
The Press and Tap invokes a right click which is generated by default under the first stylus. This behavior can be changed to generate the right click under the second stylus. |
| Four finger swipes |
In OS X Snow Leopard, four finger swipes typically invoke one of the "Expose" features, or invoke the application switcher. Unfortunately there's no supported way to programmatically activate these features, so UPDD Gestures posts keystrokes that trigger them. Since the hot key for the "Expose" feature can be configured, UPDD Gestures reads in the Apple hot key preferences to determine which keystroke is the correct one to press. We believe this works quite successfully and in our test these features get activated consistently. We are keen to find out if it works consistently for our users – any feedback much appreciated! |
| Scroll direction |
Given that touch screens are absolute pointer devices operating directly top of the video then, by default, gestures scrolls the contents of a window the same direction as your finger movement. However, trackpads have a scroll direction option under System Preferences to scroll window content with or opposite to the finger movement (Natural option checked or unchecked). E.g. scrolling to the left to view the contents under the left side of a window, meaning that that data has to scroll right to reveal the left side contents. Since gesture version 2.0.60 there is now a setting for scroll direction to "scroll", "swipe between full screen apps", and "pan screen" actions. |
| Scroll & swipe between pages |
Since 2.6.3 we added checkbox to 'Scroll & Swipe between pages' action options that allows disabling swipe between pages. When doing a scroll gesture, it will either always or never perform a 'swipe between spaces' action depending on whether the 'disable swipe between pages' check box is checked, regardless of system settings. Swipe between pages is enabled by default. |
| Navigate between pages |
In native use the 'Navigate between pages' gesture action works on the Window that is currently active not at the mouse cursor position. For example, "Navigate between pages" can be used successfully to go back and forward in a Safari window as long as it is frontmost and active, even when the mouse cursor is in a different location / display. Since gesture version 2.6.4 we have added an option to 'Navigate between pages' gesture that allows focusing the window under the gesture which defaults to on.

| Double click / double tap |
Setting the tap gesture action to click then tapping twice will produce a double click (and triple clicks and so on) as expected and this is the most obvious method of producing double clicks. However, there is also a ‘double tab’ gesture and ‘double click’ action……
The purpose of the 'double tap' gesture allows double tapping to produce a different action than a single tap, however this causes single taps to be delayed because Gestures needs to determine which of the two gestures is being performed before any action is triggered.
The 'double click action' can be associated with a gesture such that gesture will always perform a double click (e.g. having a three finger tap trigger a double click).
It is not necessary to set the double tap gesture to the double click action be able to generated double clicks and in fact will introduce a delay in single clicks. Be warned! |
