The video above shows how the Xbox Kinect can interact with your Windows Phone 7 handset to make your life easier with certain tasks. An example shown in the video is an advert for Toyota. Simply activating Kinect's voice control and announcing "Near Me" will bring up a map showing the nearby locations of Toyota garages. Then a simple text message or email can be sent to your WP7 with the co-ordinates.
This example aids in local advertising and minimises time for the end-user compared to opening a browser, searching Bing etc.
