  1. Information &Interaction Design Fall 2005 Bill Hart-Davidson Session 2: Team & Project intros; Activity Analysis; Phase 1 presentation and Memo guidelines;

  2. Teams discuss project ideas (part 1) Exercise 1: Activity Analysis Guidelines for Presentation #1 Guidelines for Requirements memo Today in Class…

  3. Remember Activity… Consider 3 levels of action: 1. Activities that are motivated 2. Action that are goal oriented 3. Operations that have conditions Note that most complex activities are comprised of all three…so…

  4. Tell us about your project What… 1. Activities go on there? 2. Actions make up those activities? 3. Operations characterize the specific conditions? What do you aim to transform and why?

  5. Identify Activity Select Instances Initiate Contact Plan Observation Observe Document Mediation Follow Up Interview Observing Activity: The Steps

  6. Begin with your Project: An Activity and a Problem A general sense of what your activity is… Filing run reports to support emergency 911 calls A general problem users are having: How can EMTs more easily, accurately record patient information on emergency runs

  7. Identify An Opportunity & Target User Group A general sense of the technological solution: A way to extend current PDA technology to the emergency care market. Describe user group in some detail…who? In what kind of situations? EMT’s on emergency runs…

  8. Think about Actions & Activity What would participants be doing when they use this HCI? Going on a call, taking patient history, administering care, documenting services Why would participants be taking these actions? How does patient info, documentation, etc. help them to provide care & transport for patients?

  9. Target the Activity to Observe Participants + Actions + Activity We will observe (participants) doing (actions) for the purpose of (activity). We will observe EMTs going on a call to provide care and transport for emergency victims

  10. Choosing Mediations to Watch Low-tech instances represent • the opportunity • the market & its problems High-tech instances represent • current directions • the competition & its mistakes At any given time in culture, expect to find: • high-tech instances: activity mediated by state of the art technologies • low-tech instances: activity mediated with legacy tech

  11. Choose Low Tech • Less constrained by leading edge solutions • More free to innovate • Currently, some EMTs use PDA’s; most use paper forms • Observe EMTs using paper forms

  12. For Assignment next week: You’ll be doing 1 observation for homework next week, then 2-3 more for your requirements phase report Identify participants, actions and activity that you will target with your HCI design.

  13. Locate & Group Participants Group by • experience • gender • affiliation • interest • or any other relevant attribute Who • might use this HCI? • is my real user? • Is available, willing, interested?

  14. Typical Critical Advanced Beginner Selecting Participants multiple observations of the same kind of participant single observations of several kinds of participants or X, Y, Z x x Choose your own user attributes

  15. For Assignment next week: You’ll be doing 1 observation for homework next week, then 2-3 more for your requirements phase report Teams of 2 should observe 2 instances; teams of 3-4 should do 3 instances

  16. Introduce Your Purpose • I am ___ • Working on a project • Want to understand how ___ • You look like a good person to talk to because ____ • Would you be willing to help?

  17. Identify What You Want • Watch you ___ • Collect some samples of ___ • Interview you ___

  18. Inquire about Frequency, Duration and Scheduling How long does a typical run take? How often do you go on one? When do they usually occur? Your Purpose: When can I observe?

  19. Inquire about Partners & Others • Are there others along with you on runs? Who are they? • Your Purpose: Are there others that I must arrange with?

  20. What to watch: a working session • 2 hours or less • typical for the participant • results in an identifiable product or outcome by which success can be measured • occurs frequently Be sure to get permission ahead of time! Try out recording practices first too, rehearse if you can

  21. Recording Practices • tape recording • video recording • note taking • screen capture (download.com) • timing technology Note taking is the primary goal here, all of the other tools should help you take accurate notes…

  22. When you start… • Define purpose • Review available artifacts and tools • Get permission to record on site • Start recording Here’s where having a pre-designed note format and a rehearsed procedure will help!

  23. Take Time-Stamped Notes On actions: 12:31: opened file “My schedule” On comments representing goals, concerns • 12:32: “Just trying to remember where I was” On changes in mediation • 12:37: Reaches for piece of paper, Memo dated 12/12/97

  24. Time-Stamped Notes, 2 On comments of emotion: 12:39: “wow, there are, like, a ton of buttons here!” On artifacts produced • 12:50: created new to-do list, called do1/22/20001.doc On task success & failure • 12:52: overwrote to-do list file

  25. Collect & Duplicate Artifacts • Get copies of initial and revised files • screen dumps • xeroxes of all papers consulted • xeroxes of all paper written on Try to match up artifacts & tools – take note of tools used and any interactions that seemed important

  26. The follow up interview, 1 Used to: • confirm routine activity, mediation, and outcome • Explore alternate conditions & scenarios I saw you doing X, is that typical? What happens when the phone rings in the middle of X?

  27. The follow up interview, 2 Used to: • Get personal history • Get institutional history How long have you been doing X this way? Is this way of doing X a standard way?

  28. The follow up interview, 3 Used to: • Identify dissatisfaction & problems • Explore plans for future changes What would you like to do differently? Are there any plans to change X?

  29. Products of Your Observation 1. Time-stamped notes 2. Documentation of tools and artifacts 3. Personal and Institutional History A basis from which to do further User-Needs Analysis, and to begin your design work…

  30. Identify actions Note Duration Construct Activity Graph Assess Typicality Identify opportunities to develop task support Analyzing Observation Data

  31. Identify Actions An action is a set of operations by a distinct set of participants using a distinct set of artifacts and tools. • Segment notes at changes in participants, acts, or tools • Name and define the action to answer the question “What?” • Use a single set of categories

  32. Raw Data 1 16:07 Joe closes door; leaves station 16:10 Joe writes on run report: dispatch information 16:11 Carla prepares equipment for possible cardiac 16:13 arrive at 2 family house

  33. Raw Data 2 16:14 woman crying about husband inside 16:15 man found lying in bed 16:16 Carla takes first vitals; look okay 16:20 man moved to stretcher 16:21 Carla asks wife some questions; doesn't write

  34. Segmented data 1 Name: Riding Definition: going to the scene prior to arriving at the scene; minimal writing to record dispatch information Segmentation 16:07 Joe closes door; leave station ….. 16:13 arrive at 2 family house

  35. Segmented data 2 Name: Routine Care Definition: providing treatment to patient and filling out some parts of run report Segmentation 16:13 arrive at 2 family house …. 16:44 Joe calls in; gives patient information

  36. Tricky things about actions… • Watch for actions embedded in other actions • Pay attention to the way tools are associated with actions • Keeping a running log of events is important, you’ll need it to do your duration analysis later

  37. Charting Duration: Your Log CLOCK ACTION MINUTES 16:07 RIDING 6 16:13 ROUTINE CARE 31 16:44 RADIO REPORT 2 16:46 ROUTINE CARE 7 16:53 F-TO-F REPORT 5

  38. Calculate Percentage of Total ACTION ?/83 min % RIDING 6 / 83 7% ROUTINE CARE 31 / 83 37% RADIO REPORT 2 / 83 2% ROUTINE CARE 7 / 83 8% F-TO-F REPORT 5 / 83 6%

  39. Activity Graph

  40. Reading an Activity Graph • X axis = % of working time • y axis = activity • length of the horizontal =relative duration of action • height of line =type of action The activity graph gives us a tool to see patterns, and a chance to ask about typicality

  41. Why Use Graphs? We graph multiple instances to understand: • Standard set of actions • Standard order of actions • Standard duration • Standard onset

  42. Use graphs to discover how activity is developing: • Direction & reasons for individual change • Direction & reasons for variations across institution • Dissatisfactions, conflicts, plans

  43. Use Graphs to Guide Design • Design for what actions? • Design with what mediation? • Design with what transitions? • Design for what contingencies?

  44. Activity Homework: Basics • Post to your team page by next week • Present it to the class on 2/2 and be prepared to discuss

  45. Components of Activity Homework For at least one set of notes on an observation: 1. Segment your notes into actions 2. List and define each action and its associated mediational means 3. Draw an activity graph of the data 4. Post these to your team page

  46. Requirements Phase - components • Activity Analysis • Requirements Presentation • Requirements Memo (draft for consultation one week after phase 1 presentation; final due one week after consultation)

  47. Phase 1 Presentation: Content • Introduce team members • Project Goal – What social practice do you intend to transform? • Background: project context • Background: current scenarios of use, users, and existing technologies • Preview of transformed scenarios of use and technologies

  48. Presentation Quality: Preliminary Research • Project Goal – What social practice do you intend to transform? - other projects like this one? - readings on issues involved • Background on project context • Site visit, activity analysis, interviews • Background on activities, users, and existing technologies - pictures, sketches, documents, etc. collected from current site

  49. Presentation Guidelines • 15 minutes, total • Think 8-10 slides • All group members participate

  50. Peer Review • Email within 48 hours • Copy to Bill • Feedback should be designed to be used in finalizing memo
