Multitouch Interface Is Starting to Spread Among New Devices

Feb. 4, 2008 — -- 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.

The best-known example of the interface is on Apple's iPhone and iPod Touch devices. It allows you, for example, to rapidly flip through photos, lists of emails or song titles by merely "flicking" a fingertip on its screen, or to resize a photo by "pinching" the image with two fingers. And, this month, Apple moved some of these multitouch features onto a laptop, its new MacBook Air, where fingertip actions are performed on an oversized touchpad rather than on a screen.

Apple didn't invent the multitouch concept. Academic and commercial researchers, and small, obscure companies, have been working on it for years. Apple is adapting the concept, adding its own ideas and popularizing it -- just as it did in the 1980s with the mouse and the graphical user interface, which had also been invented elsewhere.

Rival companies are scrambling to add multitouch features to laptops and other digital gadgets. Synaptics, a leading supplier of touchpads for laptop makers who compete with Apple, has announced that shortly it will incorporate several multitouch features into its touchpads. Microsoft is producing a coffee-table-size computer called the Surface, meant for hotels, casinos and retail stores, that uses multitouch finger gestures to move around digital objects such as photos, play games and browse through product options. Hewlett-Packard developed a prototype of a similar multitouch coffee-table computer for home use.

And, in the back rooms of this month's Consumer Electronics Show in Las Vegas, various cellphone makers, seeking to emulate the iPhone, were showing off their own unannounced efforts at multitouch. One prominent cellphone maker, Taiwan-based HTC, has already built a phone, called the Touch, which slaps a rudimentary multitouch interface on Microsoft's Windows Mobile operating system.
