Using the Touch Screen

Embedded infrared optical sensors of your computer's touch screen enable direct interaction with the computer using your 
finger(s). You can perform various gestures on the touch screen to compensate for mouse operations, such as selecting items 
and scrolling.

The touch screen function may be disabled depending on the software application you are using.

You cannot use some touch screen functions while the Quick Web Access function is activated.

Your computer is equipped with two optical sensors and supports multi-touch input of up to two points. When you rotate a picture on the touch screen, 
for example, a rotating gesture may not be successfully recognized by your computer, which, however, does not indicate a malfunction.

The touch screen function is disabled while you are using the HDMI/VIDEO input function. See Using the HDMI/VIDEO Input Function 

 for 

more information.
