The future of touch as an interface tool
Touch screens have been around in specialized applications for some time but interfacing by touch has not been mainstream except for laptop touchpads. That may be changing and Walt Mossberg devoted his Thursday consumer electronics column to the subject of touch as an interfacing method. He begins:
We are now witnessing the emergence of a new user interface for digital devices, including laptop computers, advanced cellphones, wireless portable data gadgets and other types of computing products.
This interface is generally called “multitouch,†and it involves using one or more fingers on a screen or touchpad to perform special gestures that manipulate lists or objects on a screen — without moving a mouse, pressing buttons, turning scroll wheels or striking keys.
