1 Today Ubiquitous Computing TDA471 Course Information A few words about Interaction Design Overview of Ubiquitous Computing Home work Teachers Olof Torgersson Responsible for the course Literature seminars Project supervision Lalya Gaye Course assistant Technology supervisor Project suprvision Course Aim The concept of ubiquitous computing deals with a world where computational technology and services permeate almost everything around us, yet fulfils human needs far better than most technology does today. This course aims to give insights in the theory and philosophy of ubiquitous computing as well as practical skills in developing such systems

2 Learning outcomes After completion of this course, the student should be able to: Understand and reflect on the theory and philosophy of ubiquitous computing Reflect upon the effects of a society where computational technology permeates every aspect of our lives Discuss and criticize designs in the area of ubiquitous computing Design computational things using non-traditional ways of realising the interaction between man and machine After completion of this course, the student should be able to: Understand how computational technology can be understood and used as a material for design of interactive systems Apply knowledge of hardware, software and other design materials into the design of artefacts with embedded information technology Carry out the development of a prototype of a ubiquitous computing system from concept development to working prototype Present and document your work through both oral and written presentations Ubiquitous Computing Movie Minority Report Check use of IT "Ubiquitous Computing is fundamentally characterized by the connection of things in the world with computation (Mark Weiser)

3 ubiquitous yo!!bikw"t"s adjective present, appearing, or found everywhere : his ubiquitous influence was felt by all the family cowboy hats are ubiquitous among the male singers. Prescence of IT-artefacts DERIVATIVES ubiquitously adverb ubiquitousness noun ubiquity -w"t# noun ORIGIN mid 19th cent.: from modern Latin ubiquitas (from Latin ubique everywhere, from ubi where ) + -ous. Thesaurus ubiquitous adjective the ubiquitous golden arches of burgerdom OMNIPRESENT, ever-present, everywhere, all over the place, pervasive, universal, worldwide, global; rife, prevalent, far-reaching, inescapable ANTONYM rare. $ Ubiquitous Computing In short about what happens when we become surrounded by IT-artefacts in our daily and working lives Distributed interactive computing permeating the world Perspectives Computer Science Sociological Science Interaction Design Talk some about ID next

4 Impact Prescence of IT-artefacts Interaction Design Design? Interaction design concerns the design of computer-based products and systems with a focus on their intended use. Interaction Design Chalmers 2006 The design of everything that is both digital and interactive. Moggridge 2007 The shaping of use-oriented qualities of a digital artifact the imaginative jump from present facts to future possibilities Page 1966 A goal-directed problem-solving activity Archer 1966 The optimum solution to the sum of the true needs of a particular set of circumstances Matchett 1968 Löwgren

5 Design materials The IT Material Some Properties The design material of Ubiquitous Computing Behaviour the result of executing a program Changes over time - Temporal Gestalt Device for interaction - Spatial Gestalt Flexible Time - Interaction

Non-traditional interaction Distributed through environment

7 History of Interaction Before proceeding with Ubiquitous Computing something about how our interaction with IT-artefacts has evolved over time History of Interaction Era 1: Mainframes (past) Central, powerful and expensive computer Many users access a single computer from dumb terminals Used for enterprise data processing Cobol, data bases, etc.. Computer not easily accessible History of Interaction Era II: Personal computers (present) Powerful and relatively inexpensive computers At least one machine per user Used for word processing, personal productivity applications, video, audio etc Powerpoint, MS Word, Web browser etc.. Computer still not that accessible History of Interaction Era III: Post-PC (future) Explosion in number and variety of computing devices A number of devices/machines share one user Devices (inexpensive) vary in complexity and function Used to make our lives better Computers become invisible

8 Three Waves Mainframe computing (60 s-70 s) massive computers to execute big data processing applications very few computers in the world Desktop computing (80 s-90 s) one computer at every desk to help in business-related activities computers connected in intranets to a massive global network (internet), all wired Ubiquitous computing (00 s-?) tens/hundreds of computing devices in every room/person, becoming invisible and part of the environment WANs, LANs, PANs networking in small spaces Movie The Office of the Professional before the mouse Ubiquitous Computing Coined by Mark Weiser and researchers at Xerox Palo Alto in the late 80s. Computers as we know them will be replaced by a multitude of networked computing devices embedded in our environments, and these devices will be invisible in the sense of not being perceived as computers. Ubiquitous computing pushes the user interface away from the desktop and into our everyday environments. Ubicomp Vision The computer for the 21st century (1991) As technology becomes more embedded and invisible, it calms our lives by removing the annoyances... The most profound technologies are those that disappear. They weave themselves into fabric of everyday life until they are indistinguishable from it

How can we design IT-artefacts and ITenvironments using computational technology as a material? What computational infrastructure do we need? UC Issues HCI how to address many computers (without going insane) Security & Privacy Wireless data, overcoming surveillance Communications & Networking Home Networks, Personal Area Networks, Ad-hoc Networks Operating Systems Must fit in small memories, energy aware Hardware Design Small size, low weight, low power, harsh environments Software Design Cope with large variation in hardware, partition the code to be easily customized in different environments

11 Design Perspective Toward a hybrid design Combine unique capabilities of computer technology with properties of physical environments Focus on foreground activity: how people interact with their designed environment preserve familiarity and accustomed use Interaction with Physical Artefacts / Environments Physical/Tangible Interaction Physical affordances: suggesting and guiding action Distributed interaction: actions across artefacts / space Spatial/ambient interaction Spatial organisation of action/communication Ambient interaction: spatial attention model Technical Perspective Computers in the Background Computers as secondary artefacts (embedded/situated) Embedded: (only a) part of some other artefact Situated: meaningfully placed, designed for specific context ( context-made rather than context-aware ) The Environment is the Interface Build upon affordances of the primary artefact or environments Don t break with accustomed uses and familiar concepts Physical I/O (sensors/actuators) to tie computers to entities in the physical environment Networking to enable coherent interaction Spatial interaction, proximate networking, etc Allow for new interactions/relationships across parts of the environment Recap Movie ambientroom metadesk Ubiquitous Computing concerns how computational technology becomes a natural part of our lives Involves both technology and interaction design Moves away from traditional desktop interaction Computation becomes embedded in the environment Next a few words about design methodology

At Chalmers we study 15 hec in 7 weeks Therefore the working week for students at Chalmers is roughly 55 hours Accordingly, this course may require 27 hours per week Home Work The Computer for the 21st Century Mark Weiser, original Ubicomp vision A History of Interaction, from Where the Action is, by Paul Dourish General history Tangible Bits: Towards Seamless Interfaces between People Bits and Atoms The concept of Tangible Computing Should be read by Wednesday morning Next Time Lalya Gaye on Locative Media More about the course project Project groups Exercise
