  11. Android Book • Sayed Y. Hashimi, Satya Komatineni: Pro Android. Apress, 2009. ISBN 1430215968. – General introduction into the concepts of Android – Recommended for exercises and project • Lots of other books on Android available – Your choice Michael Rohs MMI 2: Mobile Interaction WS 2011/12 11

  12. Early Mobile Communication Devices • 1946 AT&T first commercial mobile phone service for private customers – Mounted in vehicles – Weighted 80 lbs • 1972 Motorola prototype for Portable Radio Telephone – First mobile phone call April 3, 1973 – DynaTAC 8000x first mobile telephone • could connect to the telephone network • could be carried by the user – www.cbc.ca/news/background/tech/cellphones/firstcellphone.html Martin Cooper (considered the inventor of the mobile phone) 12 Michael Rohs MMI 2: Mobile Interaction WS 2011/12 12

  13. How Times Have Changed • “In 1954, the Marquis of Donegal heard that the Duke of Edinburgh possessed a mobile radio set with which he phoned through to Buckingham Palace – and anyone else on the network – while driving in London. The Marquis was more than a little jealous, and enquired of the postmaster general whether he, too, could have such a telephone. The polite but firm reply was “no”. In the mid-1950s, if you were the husband of the Queen you could have a mobile telephone connection to the public network. But if you were a mere marquis, you could go whistle.” Agar, J.: Learning from the mobile phone. Journal of the Royal Society of Arts, pp. 26-27, January 2004. Michael Rohs MMI 2: Mobile Interaction WS 2011/12 13

  14. Today More Mobile Phones than PCs • Mobile subscribers – 5.3 billion in late 2011 – World population 7.0 bn • BRIC countries one third and fastest growing – Brazil, Russia, India, China – 2.2 bn mobile subscribers (1.3 bn end of 2008) • Europe – More than 1 mobile phone per inhabitant in some countries http://www.itu.int/newsroom/press_releases/2008/29.html Michael Rohs MMI 2: Mobile Interaction WS 2011/12 14

  15. Mobile Phone Subscribers in China Passerini et al., CACM Oct. 2007 Michael Rohs MMI 2: Mobile Interaction WS 2011/12 15

  16. Alan Kay’s Dynabook (1968) • Vision of a mobile computer with focus on UI • A portable interactive personal computer, as accessible as a book • Envisioned as a learning aid for children • Problem: software that facilitates dynamic interactions between the computer and its user • “The Dynabook will have considerable local storage and will do most computing locally, it will spend a large percentage of its time hooked to various large, global information utilities which will permit communication with others of ideas, data, working models, as well as the daily chit-chat that organizations need in order to function. The communications link will be by private and public wires and by packet radio.” http://www.artmuseum.net/w2vr/archives/Kay/01_Dynabook.html Michael Rohs MMI 2: Mobile Interaction WS 2011/12 16

  17. “Dynabooks” Today • Field work supported by tablet PCs • Example: Work in archaeological sites – Capture notes and images – Exchange data – Match items to databases • Source: www.apple.com/ipad/pompeii Michael Rohs MMI 2: Mobile Interaction WS 2011/12 17

  18. Mobile Interaction is Usage in Context • Primary real-world task Adapted from a slide by Albrecht Schmidt Michael Rohs MMI 2: Mobile Interaction WS 2011/12 18

  19. Mobiles “in the Wild” and “on the Go” • Interruptions – From environment or device itself – Short attention periods • Changing environments – Noise, lighting conditions • Full concentration on device impossible – Cognitive capacity shared with other tasks • Presence of others, social situation – Incoming call changes social situation • Importance of events in environment – Environment provides relevant information – Acting in the environment based on combination Michael Rohs MMI 2: Mobile Interaction WS 2011/12 19

  20. Ubiquitous Computing “The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it.” Mark Weiser • Computers embedded in everyday things • Technology moves into the background • Computers in the world, instead of world in the computer • Mobile devices as always available mediators • Entry point into the digital world Michael Rohs MMI 2: Mobile Interaction WS 2011/12 20

  21. What can you do with your phone? http://www.youtube.com/watch?v=Pgsw-NgDoFE Michael Rohs MMI 2: Mobile Interaction WS 2011/12 21
