Figure 2: Touch screen phone Figure 2 shows a picture of a touchscreen phone. The hinges allow the phone to flip open and fold to close in order to become more compact. When flipped open, the phone's speaker and microphone are placed closer to the operator's ear and mouth, thereby improving usability. Figure 3: A flip phone The Slider Phone A slider or slide phone is composed of usually two, but sometimes more, sections that slide past each other on rails.
It usually has a display segment which houses the speaker and screen, while the segment that slides in and out contains the keypad or keyboard. The sliding form factor allows the owner to take advantage of a full key board without sacrificing portability. Figure 4 Figure 4: A slider phone shows a picture of a slider phone.
