Multi-Touch : Multi-Touch With its large Multi-Touch display and innovative software, iPhone lets you control everything using only your fingers. Type using the predictive keyboard, glide through albums with Cover Flow, scroll through photos with a flick, or zoom in and out on a section of a web page — all courtesy of Multi-Touch. How it works - The Multi-Touch display layers a protective shield over a capacitive panel that senses your touch using electrical fields. It then transmits that information to the LCD screen below it. And the iPhone software enables the flick, tap, and pinch.

Accelerometer : Accelerometer iPhone responds to motion using a built-in accelerometer. When you rotate iPhone from portrait to landscape, the accelerometer detects the movement and changes the display accordingly. So you immediately see the entire width of a web page, view a photo in its proper aspect ratio, or control a game using only your movements. How it works - The accelerometer inside iPhone uses three elements: a silicon mass, a set of silicon springs, and an electrical current. The silicon springs measure the position of the silicon mass using the electrical current. Rotating iPhone causes a fluctuation in the electrical current passing through the silicon springs. The accelerometer registers these fluctuations and tells iPhone to adjust the display accordingly.

Ambient Light Sensor : Ambient Light Sensor The ambient light sensor in iPhone automatically brightens the display when you’re in sunlight or a bright room and dims it in darker places.

Proximity Sensor : Proximity Sensor When you lift iPhone to your ear, the proximity sensor immediately turns off the display to save power and prevent inadvertent touches.
