The 5 Pen PC technology allows 5 pens to function as the core components of a portable computer. Each pen serves a distinct purpose: the CPU pen functions as the computer's processor, the camera pen contains an integrated digital camera, the visual keyboard pen projects a keyboard interface, the display pen works as an LED projector, and the communication pen enables cellular connectivity. Together, these 5 pens integrate the main functions of a CPU, camera, keyboard, display, and phone into a wireless, portable computer system that is lightweight, compact, and has a battery life of up to 2 weeks.
