Introduction of 5 pen PC Technology
  • Last Updated : 30 Jul, 2020

5 pen PC technology is a computer technology in style of pen. It was developed in 2012 by a Japanese Technology Company, NEC. This technology consists of an input device with input that can be taken from handwriting, a Central Processing Unit, a small projector and a camera along with a mobile phone.

All devices communicate with each other using wireless Technology (Wi-Fi) and it can be connected to mobile phones and other internet connections.

It was developed by Toru Ichihash. This technology uses 5 pens in making a computer. These work as different parts of a computer such as a CPU, a camera, a virtual keyboard, a projector and a phone. All these are placed on a holder, called base, that holds and charges their batteries. We can get a digital copy of handwritten data and it can even be directly sent as mail.

Working :
Using 5 pen PC technology, monitor and keyboard is produced on a flat surface. The functions of these keyboards and monitors are similar to a normal personal computer (PC). It mostly uses pen (stylus) for input. It uses a special Operating System that supports handwriting recognition. It is a small handheld device.

Functionalities :
It has the following functionalities.



  • CPU pen –
    This is used as computing engine. All processes and calculations are processed here.
  • Communication pen –
    This is used as a mobile phone and pointer. It can also be used as an earpiece that uses Bluetooth for communication.
  • Projector pen –
    This is an LED projector of approximately A4 size with a resolution of 1024×768.
  • Keyboard pen –
    This is a virtual keyboard. It can be projected on any flat surface using 3D IR Sensors.
  • Camera pen –
    This pen is used for clicking pictures, audio and video recordings. It can take 360 degrees of visual.
  • The base is actually a holder for 5 pens and also is a charger and acts as a mass storage unit.
    It can go upto 6 days. For normal use it would work for 2 weeks.

Advantages :

  1. It is Portable.
  2. It has a very long lasting battery life.
  3. It reduces electronic waste.
  4. Virtualization reduces costs.
  5. It is much lighter than a traditional portable computer.

Disadvantages :

  1. The positioning of pens is very important. Slight disturbances would hamper entire setup.
  2. Cost might be high due to technology being new.
