In yesterday’s column, I mentioned that I was going to use today’s column to tell you about the gestures that are supported by Windows 7’s touch interface. Some of the gestures that are supported are pretty obvious. For example, you would probably expect to be able to tap, double tap, drag, and scroll. There are some other less obvious ones though.
One example of this is that you can invoke the zoom function by moving two fingers together (in a pinching motion) or by moving them apart.
There is also a gesture called a two finger tap. The two finger tap causes the area where you tapped to be zoomed in (or restored to its previous size). To be able to use this gesture though, you must be using an application that was specifically coded to support it.
Another gesture that requires special coding is the rotate gesture. To use this one, just touch two different spots on a digital photo, and then slide your fingers. The photo will be rotated in the direction of your fingers.
Windows 7 also supports a flick gesture, that is similar to the one used on the iPhone. Any application that uses a back button supports this gesture.
You might have noticed one very important gesture missing from the list… the right mouse click. You can use a touch interface to perform a right mouse click, but it isn’t exactly intuitive. You can either press the screen and hold it, or you can press the screen, and then tap the screen with a second finger. Either of these gestures does the same thing as a right mouse click.
