What is Mobile Computing? ØMobile 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 Ø Many types of mobile computers have been introduced since the 1990 s, including the: Ø Wearable computer Ø Personal digital assistant/Enterprise digital assistant Ø Smart phone Ø Carputer Ø Ultra-Mobile PC

WEARABLE COMPUTER Ø Wearable technology has been used in behavioral modeling, health monitoring systems, information technologies and media monitoring systems , information technology and media development.

Ø 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.

ØOne of the main features of a wearable computer is consistency. Ø There is a constant interaction between the computer and user, ie. there is no need to turn the device on or off. Ø Another feature is the ability to multi-task. Ø These devices can be incorporated by the user to act like a prosthetic.

Uses of Wearable Computer Ø 1980 s Ø The 1980 s saw the rise of more general-purpose wearable computers. In 1981 Steve Mann designed and built a backpack-mounted 6502 based computer to control flashbulbs, cameras and other photographic systems.

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

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

PERSONAL DIGITAL ASSISTANT Ø A personal digital assistant (PDA), also known as a palmtop computer Ø Many PDAs can access the internet, intranets or extranets via Wi-Fi, or Wireless Wide Area Networks(WWANs). Many PDAs employ touchscreen technology.

TYPICAL FEATURES Ø Ø Ø Touch screen Memory cards Wired connectivity Wireless connectivity Synchronization

TOUCH SCREEN Ø PDAs, such as the Apple Newton and Palm Pilot, featured touchscreen for user interaction. Ø Touch screen PDAs, including Windows Mobile devices, usually have a detachablestylus that can be used on the touch screen

Text input is usually done in one of four ways Ø Ø virtual keyboard External keyboard or chorded keyboard Ø letter or word recognition Ø Stroke recognition The Palm TX

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

SMART PHONE Ø A smart phone is a mobile phone offering advanced capabilities, often with PC-like functionality (PC-mobile handset convergence). Ø There is no industry standard definition of a smart phone. Ø 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 Ø Operating systems that can be found on smart phones include Symbian OS, i. Phone OS, Palm Web. OS, Black. Berry OS, Samsung bada, Windows. Mobile, Androi d and Maemo which all are related to Unix. Market Smart phone of share operating system sales for 2009

ADVANTAGES OF MOBILE COMPUTING Ø Ø Ø 12345 - providing wider reach. reducing transaction cost streamline business processes. competitive pricing. reducing time to order.

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

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