What is Mobile Computing?
Mobile computing is a generic term
describing one's ability to use technology
while moving, as opposed to portable
computers, which are only practical for
use while deployed in a stationary
configuration.
Types of Mobile Computers
 Many types of mobile computers have
been introduced since the 1990s,
including the:
 Wearable computer
 Personal digital assistant/Enterprise
digital assistant
 Smart phone
 Carputer
 Ultra-Mobile PC
WEARABLE COMPUTER
 Wearable technology has been used
in behavioral modeling, health
monitoring systems, information
technologies and media monitoring
systems ,information technology and
media development.
 Wearable computers are especially
useful for applications that require
computational support while the
user's hands, voice, eyes, arms or
attention are actively engaged with
the physical environment.
One of the main features of a wearable
computer is consistency.
 There is a constant interaction between the
computer and user, ie. there is no need to turn
the device on or off.
 Another feature is the ability to multi-task.
 These devices can be incorporated by the
user to act like a prosthetic.
Uses of Wearable Computer
 1980s
 The 1980s saw the rise of more
general-purpose wearable computers.
In 1981 Steve Mann designed and
built a backpack-mounted 6502based computer to control flashbulbs, cameras and other
photographic systems.
 A wrist
wearable touch screen
computerwith GPS, WiFi
and Bluetooth connectivity and which
can run a number of custom
applications
Commercialization

computer from Arcom Control Systems
Military use
 The most extensive
military program in
the wearables
arena is the US
Army's Land
Warrior system
 which will
eventually be
merged into
the Future Force
Warrior system
PERSONAL DIGITAL ASSISTANT
 A personal digital assistant
(PDA), also known as a palmtop
computer
 Many PDAs can access
the internet, intranets or extranets
via Wi-Fi, or Wireless Wide Area
Networks(WWANs). Many PDAs
employ touchscreen technology.

SMART PHONE
 A smart phone is a mobile phone offering
advanced capabilities, often with PC-like
functionality (PC-mobile handset
convergence).
 There is no industry standard definition of a
smart phone.
 For some, a smart phone is a phone that
runs complete operating system software
providing a standardized interface and
platform for application developers.
OPERATING SYSTEM
 Operating systems
that can be found on
smart phones
include Symbian
OS, iPhone OS, Palm
WebOS, BlackBerry
OS, Samsung bada,
WindowsMobile, Androi
d and Maemo which all
are related to Unix.
