Multi-touch
iPod touch features the same revolutionary interface as iPhone. Built to take full advantage of the large 3.5-inch display, the multi-touch interface lets you control everything using only your fingers. So you can glide through albums with Cover Flow, flick through photos and enlarge them with a pinch, or zoom in and out on a section of a web page. And iPod touch features a touchscreen QWERTY keyboard perfect for browsing the web in Safari, searching for videos on YouTube, finding music on the iTunes Wi-Fi Music Store, or adding new contacts.
Ambient Light Sensor
The iPod touch display has an ambient light sensor that automatically adjusts brightness to suit the ambient light in your surroundings. The result? A better experience for you and battery-saving efficiency for iPod touch.
Accelerometer
An accelerometer detects when you rotate iPod touch from portrait to landscape, then automatically changes the contents of the display, so you immediately see the entire width of a web page, your music in Cover Flow, or a photo in its proper aspect ratio.
