"Multiple Natural-User-Inputs" interface from Microsoft

Instead of allowing users to interact only with touch or only with speech, Microsoft is working on interfaces that will combine multiple natural-input techniques (especially with Windows 7 and Windows Mobile 7).
Microsoft officials showed off a demo of an automated front-desk receptionist, which the company plans to deploy internally later this year.
The automated receptionist, it turns out, is one of the fruits of a Microsoft Research effort, known as the “Situated Interaction project.”
