Saffer, Designing Interaction: Cognitive Innovative Applications and Devices, New Riders, Berkeley, CA, 2010. What is Interaction Design? (1) What is Interaction Design? (2) Not well defined Interdisciplinary roots in: industrial and communication Design is to design a design to produce a design design, human factors, and human-computer interaction John Heskett Interaction Design Much of interaction is not visible E.g., Though Windows and Mac operating systems may have almost the same functionality and look, yet, they feel differently Interaction is about behavior and behavior is difficult to observe and understand 1 2/1/2010 Interaction Design Perspectives Focus of Interaction Design (1) Focusing on users o Designers should advocate users’ expectaions Finding alternatives Technology centered o Designing is not choosing among multiple options, o E.g., use of digital technology o It is about creating options (Genetic programming link) Behaviorist Using ideation and prototyping o Study product behavior and users’ feedback o Many prototypes, e.g., Jeff Hawkins – designer of the original Social interaction design PalmPilot carried around wooden blocks and wrote on them o Facilitating interaction among products and people Collaborating and addressing constraints o Designers deal with teammates, money, materials; and address business goals, deadlines, etc. Focus of Interaction Design (2) History of Interaction Design (1) Creating appropriate solutions Likely begun with Native Americans and other tribes o Appropriate to the situation (Evolutionary computation and evolving landscape link) used smoke and other signals to communicate over Drawing on a wide range of influences long distances E. g., engineering, ergonomiergonomicscs, psychology, economics, 1930s – 40s arts In mid 1930s Samuel Morse created a system to convert Incorporating emotion electromagnetic pulses into a language (system = everything from electrical system to mechanism of tapping out the code, o Product without emotional component does not connect to people to training operators) o Other mass communication technologies required systems solutions 2 2/1/2010 History of Interaction Design (2) History of Interaction Design (3) 1940s – 60s The first computer - ENIAC was engineered, not designed. 1960s – 70s Humans had to adopt to the computer, speak its language not o 1960 – Computer network – Ted Nelson the natural one, and it was poorly usable o 1963 – Graphical user interface – Ivan Sutherland o In 1945 Vannevar Bush introduced Memorex (augmenting a o 1962 – ARPANET human memory) - a microfilm device for storing books, o 1965 – Email records, and communications o 1968 – Douglas Engelbart – Mouse demo and o Memorex was the fist concept of hypertext followed by interactive design presentation Douglas Engelbart o 1970 – Gaming industry, e.g., ATARI in 1977 o 1973 – Ethernet and beginning of Apple’s era (Steve Jobs) History of Interaction Design (4) 1980s o Apple Computer (Lisa and Macintosh) o Era of personal computers o Portable compp,uters, Osborn 1 o Concept of ubiquitous computers at Xerox PARC 1990s Case Study 1 o The era of networked computers 2000s o Era of social software and ubiquitous computing Microsoft Office 2007 o Era of products and services 3 2/1/2010 Microsoft Office 2007 (1) Microsoft Office 2007 (2) Microsoft: The world’s largest software company The Process The Problem Microsoft analyzed data created by anonymous users on In earlyy, 2000, a decision was made to redesig n Microsoft Office the use of Office 2003 A decade old interface did not scale well They looked at desirable (low frequency) features that users E.g., 50 menu items and 2 toolbars from MS Word 1.0 had could not find, and ballooned to 260 menu items and over 30 toolbars in Frequently used features that were difficult to find (users badly MS Word 2003 wanted them) Microsoft Office 2007 (3) The Solution Microsoft Office 2007 has been enhanced with 1000 improvements taking less screen space than the previous versions Minibar introduced Ribbon introduced (with some controversy) 4.
