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:1990s  Wearable computer Wearable computer  Personal digital assistant/Enterprise digital assistant Personal digital assistantEnterprise digital assistant  Smart phone Smart phone  Carputer Carputer  Ultra-Mobile PC 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.interaction  Another feature is the ability to multi-task.  These devices can be incorporated by the user to act like a prosthetic.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 based computer to control flash- bulbs, cameras and other photographic systems. Steve Mann

Commercialization IImage of the ZYPAD wrist wearable computer from Arcom Control Systems

Military use  The most extensive military program in the wearables arena is the US Army's Land Warrior system US ArmyLand Warrior  which will eventually be merged into the Future Force Warrior systemFuture Force Warrior

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.internetintranetsextranetsWi-FiWireless Wide Area Networkstouchscreen

USES OF PDA  Automobile navigation Automobile navigation  Ruggedized PDAs Ruggedized PDAs  Medical and scientific uses Medical and scientific uses  Educational usesEducational uses  Sporting uses Sporting uses  PDA for people with disabilities PDA for people with disabilities

SMART PHONE  A smart phone is a mobile phone offering advanced capabilities, often with PC-like functionality (PC-mobile handset convergence).mobile phonePC  There is no industry standard definition of a smart phone.industry standard  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 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.Symbian OSiPhone OSPalm WebOSBlackBerry OSSamsung bada WindowsMobileAndroi dMaemoUnix Market Smart phone of share operating system sales for 2009

ADVANTAGES OF MOBILE COMPUTING  1- providing wider reach.  2- reducing transaction cost  3- streamline business processes.  4- competitive pricing.  5- reducing time to order.

LIMITATIONS OF MOBILE COMPUTING  Insufficient bandwidth  Security standards  Power consumption  Transmission interferences  Potential health hazards  Human interface with device

APPLICATIONS OF MOBILE COMPUTING  Form factor of end user device  Battery life  Input method-keyboard, pen, touch or voice  Ruggedness  Whether Portable or fixed  Safety & Health issues
