Microsoft demonstrated its multitouch interface for its upcoming Windows 7 operating system on Tuesday. The interface provides a touch-screen input for users to interact with their computers.

Multitouch uses Surface technology, introduced last year by Microsoft, which harnesses touch and multitouch capabilities to provide users with a more natural way to interact directly with computing devices. Expect to see the table-like Surface devices in hotels, retail establishments, restaurants, and public entertainment venues, Chris Flores, a director at Microsoft working on the Windows Client Communications Team, said in the Windows Vista Team blog on Tuesday.

In a demo to the Wall Street Journal 's D: All Things Digital conference, Julie Larson-Green, Microsoft's corporate vice president for Windows experience program management, showed a number of applications that could use the multitouch technology, including photography applications that enable a user to handle photos on the screen more easily. The user can drag and drop snaps, zoom in, and rotate snaps with his fingers. The musically inclined can play with their fingers on an on-screen piano keyboard.

In a blog entry on Tuesday, Flores said that the long-term architectural investments Microsoft introduced in Windows Vista and then refined for Windows Vista SP1 and Windows Server 2008 will carry forward in Windows 7. Contrary to some speculation, Microsoft is not creating a new kernel for Windows 7, he said. One of the design goals for Windows 7 is that it will run on the recommended hardware specified for Windows Vista and that the applications and devices that work with Windows Vista will be compatible with Windows 7, Flores added.
