  1. Fall 2012 Prof. Searleman jets@clarkson.edu

  2.  Course objectives  Administrivia  Introduction to Interaction Design  Motivating Examples  Good & Bad Designs

  3.  This course is an introduction to the field of Human-Computer Interaction (HCI)  Students will learn how to design, evaluate and implement interactive systems from the user’s perspective

  4.  course webpage: http://www.clarkson.edu/~jets/cs459  contact info: office: SC375 & Applied CS Labs:VR (SC364) phone: 268-2377 email: jets@clarkson.edu

  7. CS459 CS559  Assignments* 20% 15%  Presentation(s) 20% 25%  Project* 40% 40%  Midterm Exams 15% 15%  Class participation 5% 5% Attendance: Participation in class discussions are an essential part of this course, so attendance is required and you must be prepared for class (i.e. have done the reading in advance). *We will be using Clarkson’s Usability Lab (in CEC)

  8.  Each student in CS459 and CS559 will deliver a presentation based on an area of human- computer interaction (a list of suggested topics and references will be posted on the course webpage).  In addition to this, each student in CS559 will also present a research-level paper to the class. All students will write a reaction paper to it (details to follow later).  The presentation evaluation sheet is online

  9.  The goal of the course project is to give you experience with designing and evaluating an interactive product.  The focus of the project is on the interaction design and evaluation, so the actual application can be a simple (but working) prototype  This can be integrated with another software project you are working on (for example, for CS350), as approved by both instructors.

  10.  Late submission policy:  Maximum 2 late days per assignment/project deliverable  Each late day penalized with 10%  No late days for presentations and test  Legal notices on the world-wide web: Read and comply with accompanying legal notices of downloadable material  Specify all references used  Plagiarism and cheating: will not be tolerated

  11. Why study Human-Computer Interaction?

  12.  Crashed near Cali, Colombia in 1995  Official cause: “pilot error”  Real cause: poor design

  13.  Boeing 757 cockpit

  14.  Pilots manually navigate only during takeoff, landing, inclement weather, emergencies.  Navigate by traveling between beacons  Flight management system

  15.  Most common way to navigate to next beacon  Enter first letter of beacon  To navigate to “ Rozo ” beacon  Pilots enter “R” on flight management system  Plane navigates towards “Romeo” beacon  Flight management system does not provide feedback on chosen beacon

  16.  Plane headed in the wrong direction, eventually crashing on a mountain  Speed brakes not disengaged when trying to accelerate http://sunnyday.mit.edu/accidents/calirep.html

  17.  Lessons  Expert users make mistakes  Feedback  Consistency  System state needs to match state expected by users

  18.  Software used to trade in Tokyo Stock Exchange  Trader for Mizuho tried to sell  1 share of J-Com for 610,000 yen  Instead he sold  610,000 shares of J-Com for 1 yen each  Software warned him, but he ignored warning  Attempted to undo, but it was not possible

  19.  Confidence in Tokyo Stock Exchange damaged  Shares in NTT, rival of software maker, jumped 11%  $331,000,000 loss from trade for Mizuho http://news.bbc.co.uk/2/hi/business/4512962.stm

  20.  Lessons  Busy people in a hurry more likely to make mistakes  Users rarely read warning messages because they rarely matter  Good designs expect mistakes to happen  Provide “undo” capabilities

  21.  Poll by UK charity found a third of men and a quarter of women drink to cope with stress  Almost one third said IT problems were a major cause of stress  Top cause of stress cited, followed by finances and commuting  Not as severe in effect as other issues (e.g. death, divorce), but much more common

  22.  Lessons  Widespread use of technology means stressful interactions can have negative impact on society http://news.bbc.co.uk/2/hi/health/4602872.stm

  23.  Technology available 10 years before WWW appeared  Graphical user interfaces  Modems  Internet  Hypertext

  24.  Interface made difference  Not geared towards experts  Tim Berners-Lee worked at CERN  Web browser  Simplicity  Consistency  Easy to recuperate from errors  Easy to learn and remember

  25.  Simple interface to access very powerful technology  Helps you notice and remediate typos

  26. iTV 3G Mobile Phones Auto Mobile iPod Cooking Arrangement Smart Fridge SMS

  27.  Ubiquitous Computing  Pervasive Systems  Tangible Interfaces  Ambient Intelligence  Context-aware Systems  Augmented Reality Increasing influence of these technologies on our day-to-day lives has fuelled a shift to user- centric design

  28.  Huma man-Com ompute puter r Inter terac actio tion (HCI) HCI) is: “concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them” (ACM SIGCHI)  Inte terac racti tion on Design gn (ID) is: Designing interactive products to support people in their everyday and working lives. (Sharp, Rogers and Preece 2007) We will concentrate on the design of computer technologies “The old computing is about what computers can do; the new computing is about what people can do” - Ben Shneiderman

  29.  Classic Software engineering  How to build functional, efficient, robust software on time given specifications  Usually not concerned with how users will interact with software  GUI design (Graphical User Interfaces)  Implies that you put something between people and code  Code developed independently from interface  Process does not start with users’ goals in mind

  30.  Academic disciplines contributing to ID:  Psychology  Social Sciences  Computing Sciences  Engineering  Ergonomics  Informatics

  31.  Design practices contributing to ID:  Graphic design  Product design  Artist-design  Industrial design  Film industry

  32.  Interdisciplinary fields that ‘do’ interaction design:  HCI  Human Factors  Cognitive Engineering  Cognitive Ergonomics  Computer Supported Co-operative Work  Information Systems

  33.  Many people from different backgrounds involved  Different perspectives and ways of seeing and talking about things  Benefits  more ideas and designs generated  Disadvantages  difficult to communicate and progress forward the designs being create

  34.  Increasing number of ID consultancies, examples of well known ones include:  Nielsen sen Norman an Group up : “help companies enter the age of the consumer, designing human-centered products and services”  Cooper: r: ”From research and product to goal -related design”  Swim: “provides a wide range of design services, in each case targeted to address the product development needs at hand”  IDEO: “ creates products, services and environments for companies pioneering new ways to provide value to their customers”

  35.  interacti raction on designer gners - people involved in the design of all the interactive aspects of a product  usabi bility lity engine neers rs - people who focus on evaluating products, using usability methods and principles  web eb des esigners gners - people who develop and create the visual design of websites, such as layouts  inform ormati ation on arch chite itects cts - people who come up with ideas of how to plan and structure interactive products  user experienc ience designer gners s (UX) - people who do all the above but who may also carry out field studies to inform the design of products

  36. Activity ivity#1 #1 (to prepare epare for class ass on Wedn ednesda esday): ): 1. Find out more about at least 4 of the terms on Slide 29, and describe them in your own words 2. Take a critical look at Peoplesoft from an HCI point of view and list three good points and three bad points. Type your answers and pass in a printout on Wednesday’s class.
