P-ISM (‘Pen-style Personal Networking Gadget Package’), which is nothing but the new discovery, which is under developing stage by NEC Corporation. P-ISM is a gadget package including five functions: a pen-style cellular phone with a handwriting data input function, virtual keyboard, a very small projector, camera scanner, and personal ID key with cashless pass function. P-ISMs are connected with one another through short-range wireless technology. The whole set is also connected to the Internet through the cellular phone function. This personal gadget in a minimalist pen style enables the ultimate ubiquitous computing.

7. 3.1 CPU Pen
• The functionality of the CPU is done by one
of the pen. It is also known as computing
engine.
• Dual Core processor is used.
• Works with windows operating system.
• It is also applicable to android and Linux
operating systems.
7

8. • There are four steps that nearly all
CPUs use in their operation: fetch,
decode, execute, and write back.
• Fetch involves retrieving an
information from memory.
• After the execution write back
operation simply writes back the
results to memory.
8

9. 3.2 Communication Pen
• It offer technologies like:
1. Bluetooth
2. WLAN
3. Cellular phone function.
• Bluetooth mechanism is used for exchanging signal
status information between two devices.
• Uses Wireless Local Area Networks (802.11)
802.11 a
802.11 b/g/n
802.11 ac
9

10. • Connected to internet through cellular
phone function.
• Its cellular network function offer a
number of advantages over other
solutions.
1. Increased Capacity
2. Reduced power use
3. Large coverage area
4. Reduced interference from other
signals
10

11. 3.3 Projector Pen
• The role of monitor is taken by LED
Projector which projects on the screen.
• Depending on how far we are from a
flat surface, this can be either adequate
or very clear.
• The size of the projector is of A4 size.
• Thus it is gives more clarity and good
picture
11

12. • Common display resolutions for a portable
projector include
SVGA (800x600 pixels)
XGA (1024x768 pixels)
720p (1280x720 pixels)
1080p (1920x1080 pixels)
• Out of these Projector pen provides Resolution
capacity of 1024 x 768.
12

13. 3.4 Virtual Keyboard
• This component works much like the
projected screen.
• It emits laser on desk which gives an
alternative input mechanism.
• It analyses what we are typing
according to the co-ordinates of the
location.
• Not only this connect to our pc, but
also our tablet, smartphone and much
more devices.
13

14. 3.5 Digital Camera
• Probably the most important part of 5
pen applications.
• The camera is very small and lodges
itself within the pen style gadget.
• It is useful in video recording , video
conferencing simply as a webcam.
• Connected with other devices using
same Bluetooth technology.
• Portable.
• 360 degree visual communication
device.

15. 3.6 Battery & Mass storage
• Is the most important part in the portable
type of computers.
• Usually batteries should be small in size and
work for a long time.
• The type of battery used here is lithium ion
battery.
• It comes with a battery life of 6+ (i.e. 6 days).
• For normal use it can be used for 2 weeks.
• Also the base includes mass storage for
storing data's.

17. 5. Merits
• It is convenient to use because of its portability. (Small
and Compact)
• It support wireless technologies like Bluetooth and Wi-
Fi
• Excellent battery backup.
• Touch and feel technology
17

18. 6. Demerits
• It works on wireless technologies and therefore it
has limitations of range.
• Gadget is very costly
• One of the components can be easily misplaced
• Projection surface should be flat for optimum
usage.
18

19. 7. Conclusion
• The communication devices are becoming smaller and
compact. This is only an example for the start of
this new technology. We can expect more such
developments in the future.
