3. 1-3 Mobile Computing - Evolution

4. 1-4 What is Mobile Computing? ��information at any time, any place, and in any form. Whether in the office, at home or virtually any place on earth.� ��mobile computing is associated with mobility of hardware, data and software in computer applications.� ��mobile computing is the use of computers in a non-static environment.� �The combination of mobile computing and wireless communications is prompting the emergence of what is referred to as pervasive or ubiquitous computing.�

5. 1-5 Mobile Computing - Today's Devices

11. 1-11 Computers Everywhere

12. 1-12 Aspects of Pervasive Computing Mobility ability to move about easily, speedily, and changing rapidly. � Embedding Placing �intelligence� in devices. Ubiquity Intelligent devices everywhere.

13. 1-13 Intelligent (Smart) Objects Real world objects are enriched with information processing capabilities Embedded processors in everyday objects small, cheap, lightweight Communication capability wired or wireless spontaneous networking and interaction Sensors and actuators

14. 1-14 Can remember pertinent events They have a memory Show context-sensitive behavior They may have sensors Location/situation/contextawareness Are responsive/proactive Communicate with environment Networked with other smart objects Intelligent (Smart) Objects

15. 1-15 Bluetooth technology is an important step in getting components that can be blended in a simpler, more understandable way. Another pervasive technology is radio frequency identifiers (RFID). These tags, which can be as small as a grain of sand, are already being used as an alternative to barcodes in some supermarkets. Intelligent (Smart) Objects

16. 1-16 Example of Smart Object Technology: A carton of milk could be tagged with a chip carrying information about its sell-by date which would tell the supermarket when to take it off the shelves. Once purchased, the same chip could be read by a fridge, which could order a new carton over the Internet before the old one goes off. Intelligent (Smart) Objects

18. 1-18 When Everything is Smart ..

19. 1-19 Embedded Technology Smart Rooms e.g. the smart home and the smart office Wearable Computing e.g. wearable within and without the body Automotive telemetry and telematics e.g. remote systems diagnosis Information Appliances e.g. self reporting household appliances

20. 1-20 Wearable Computing

21. 1-21 Wearable Computing Miniaturisation of pervasive devices Weight minimisation of pervasive devices Type/nature of device location on /in the human body The development of safe, secure, and effective data communication media Providing different forms of engagement with wearable devices that are hands-free

22. 1-22 Wearable Computing - Smart Clothing Conductive textiles and inks print electrically active patterns directly onto fabrics Sensors based on fabric e.g., monitor pulse, blood pressure, body temperature Invisible collar microphones Kidswear game console on the sleeve? integrated GPS-driven locators? integrated small cameras (to keep the parents calm)?

23. 1-23 Wearable Computing - Smart Glasses �By 2009, computers will disappear. Visual information will be written directly onto our retinas by devices in our eyeglasses and contact lenses� - Raymond Kurzweil

24. 1-24 Wearable Computing � Active Badges

25. 1-25 Body Area Networks Very low current allows some kb/s to pass through the human body Possible applications: Car recognize driver Pay when touchingthe door of a bus Phone configures itselfwhen it is touched

26. 1-26 Interactive Map Foldable and rollable

27. 1-27 Automobile Telematics - Weather Response 17% of all USA highway fatalities occur during adverse weather (Snow, Ice, Fog) Weather information is critical to travelers Existing national weather information is inadequate for highway operations Efforts to enhance this information locally are expensive and of limited value
