Google has unveiled several new features of the Android mobile communication software, including detailed use of the map street view service Google Maps Street View and touch interface functions similar to those of Apple's iPhone. On the 28th, at the Google I/O conference, Steve Horowitz, Director of Engineering for Android, in his speech, simply gestured slightly to swipe from the phone's homepage to different pages. More specially, he demonstrated how to use the built-in compass and accelerometer to control the Street View service. After calling up a certain street view of San Francisco using the browser, when Horowitz turned around, the Street View image also moved left and right, reflecting his direction.
