18 TODAY S GOAL After this lecture and its activities, you should be able to: Have an overview over where the mobile smartphone scene is today and what to read to get supplement information

19 LENDING OUT DEVICES So that you can get to know this technology Push vs pull Data+interface (web apps/sites) vs data-only services (e.g. calendar) Experience accessibility so that you can design and work with accessibility Tie into our network and services WiFi: Eduroam Email:... Social: Twitter Time: Calendar Dynamic media: podcasting

22 GENERAL TENDENCIES TODAY Lot of interest gravitates toward the mobile industry, dev. & research Heavy focus on smartphones and tablets. New devices almost daily Movement of power and money (from carriers to OS and app developers) Standardisation of UIs, equipment, apps, add-ons and infrastructure Appification of the Web Focus on the inside of devices, rather than the outside (1990-2007) Usability improves. Now not only geeks that used phones and tablets Atoms becomes bits (music, movies, newspapers, books, periodicals)

23 HIG IN 5 YEARS? Calendars, alarms and augmented reality helps you navigate in time and space around the campus? Social production of content in the cloud and easy-to-use tools to assess individual student contribution? More mobile services to help students navigate in Gjøvik? Get full access to the library content on a tablet? Most services online @ hig accessible by mobile devices? Learning management system: mobile and social? Full access to lecture streams and recordings (audio/video)? Serious games help students connect to and socialize

24 EVOLUTION? 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2007 2008 2009 2010 2011 2012

25 CHALLENGES High cost of devices and access? Radiation? Less social not more? Important focus away from the open web and into closed apps Too much compromise when replacing special hardware with mobile app solution

29 THE BASICS Mobile device Handheld computer Computer: input, processing, output. Communication and storage. Mobile OS System software controlling the operations of a handheld computer Mobile phone Feature phone (classic type, often with hardware keys) Smartphone (highly adaptable modern touch-screen based)

30 THE BASICS Mobile social network Individuals contributing to and/or drawing value from an online social network using a mobile device Web based and Native (using sensor capabilities in the device)

31 MISCELLANEOUS TERMS Ubiquitous computing (Max Weiser, Xerox Parc, 1988) computing integrated into everyday objects and activities also described as pervasive computing or ambient intelligence its base is a robust network of computing devices Context awareness The device and/or network knows something about your situation to provide you useful services Context useful to provide you services is often your location You can state your context explicitly (Path: sleeping ) or let the device use location, time, date, direction, speed and other info elements about you

32 MISCELLANEOUS TERMS

33 MISCELLANEOUS TERMS Augmented reality Often: Live view of the world on which the device puts additional information

34 COMMUNICATION Wireless: communication between entities not physically conneted. E.g. mobile phones First wireless phonecall, 1880 Big jump 100 years ahead to the GSM standard (Groupe Spécial Mobile) Expanded to include data capability (GPRS and EDGE) Later improved to form the 3G (UMTS) standard (0.2-9Mbps) Will evolve into 4G (likely LTE) standard (potential Gbps)

35 INVENTIONS Mobile phone (1973: Martin Cooper, Motorola) GSM (1982: Torleiv Maseng, SINTEF)

36 MOBILE COMMUNICATION Ship to shore and car-phones: 1930 and -40s. Different analog and digital services (1940s-1970s) 1G: 1979 2G: 1991 3G: 2001 4G: 2009

37 MOBILE COMMUNICATION PDA Term by... Smartphone Term by... Converged device

38 BUSINESS Shift of power and money From cell providers to OS and device manufacturers, including their developers Power struggle between MS, Google, Apple and RIM Earlier: Network providers gave customers curated content and access Now: Network providers more a provider of basic network access Network providers can to a less degree decide what apps and services are on the phones

39 SUBSCRIBING TO AUDIO AND VIDEO ON YOUR DEVICE Streaming content live or dynamically downloading and playing content Subcribing to and downloading previously recorded material (podcast) Podcasting interesting because it informs you and can be set to download new content (episodes)

40 TWIT.TV

41 TWIT.TV

42 PODCASTING Mechanism of subscribing to content also used for printed material/ periodicals/newspapers in the ios app store. Likely to turn up elsewhere as well

43 CASTING @ HIG? Subscribing to and automatically informed about changes in: Calendars for courses (imt2551.ical) Recorded lectures (imt2551.rss)

44 OTHER POPULAR PHENOMENON QR codes (Quick Response) two-dimentional barcode that can be translated into alfa-numeric characters today, used by mobile users to reduce typing
