More TCUID: Tasks, Scenarios, and the Design Process Slide 2 Hall of Shame Median Crossing on First Avenue in Cedar Rapids Slide 3 Sign A Sign B Slide 4 Sign A Slide 5 What's the issue? Mapping biggest issue "Do Not Enter" signs proximity of exits and entrances Constraints elevation in the road "Do Not Enter" signs Affordances openings in the median AFFORD to be turned into Signifiers mostly ineffective Feedback when every car is heading the opposite direction of you Slide 6 Objectives for today Review project deliverables for this week Continue working through TCUID Elaborate; relate to other approaches Try out some techniques Slide 7 Project: whats coming up First, check the project guide frequently! Some of you may have met with your users . So, any questions? Slide 8 Deliverables for Week 5 User Visit Report 5 Tasks 2 Scenarios Other stuff Slide 9 User Visit Report Summary of the process you carried out A user description relevant user characteristics you are considering in your design. expected range of computer and internet experience use environment special user concerns or motivations what users do today to fulfill the needs that your project aims to satisfy in a new way Slide 10 Task Analysis Descriptions of at least five (TCUID) tasks that users would accomplish with your prototype For each task description who are the users what are they doing why are they doing it At least three should be general tasks that users accomplish today Detailed enough for users to understand and comment on Not tied to a specific interface Slide 11 Current Usage Scenarios For two of the tasks, provide a detailed scenario explaining how users accomplish that task today These scenarios may involve computer software, paper, or other devices, in any combination Slide 12 Other Stuff To Include Anything else you learned from the user visit not already covered How effective was your process Lessons learned what youd do different in the future Any information you could not gather, along with either (a) plans for how you will get it or (b) how youll continue without it Slide 13 Be prepared to discuss What you learned from the analysis Any changes in your conception of the project Slide 14 Quick Review of Tasks Slide 15 Tasks A detailed description of a complete job that a specific user wants to accomplish Doesnt specify how they would do the job separate the What from the How; concentrate on the What Slide 16 Using tasks Set goals for system functionality Inform design decisions Thomas: Lets add this cool new feature!!! Sharon: Why? Which task does it support? Compare design alternatives Slide 17 From Task to Design Write-up tasks, circulate among users clarify missing details Mock up an interface, using existing systems or designs where possible Sketch out how each task would be accomplished in the interface, then develop scenarios Slide 18 Sample Task Rita Neus, the on-line production coordinator for the paper sits down at 1:30 AM before going home for the night, and Selects the stories stokeef.xy, stguns.xy, stvet.xy, stwres.xy, stcomp.sy (in that order) for the news section of the website. She decides that stvet.xy should be the lead story She realizes that stwres.xy is actually a sports story and moves it to that department. Slide 19 Sample Task Dr. Wenthold, head of the search committee, is in charge of setting up the schedule for the campus visit of a job candidate (Sal Lammy) on February 7 th. He schedules time to take the candidate to lunch, and dinner. 3:30-4:30 PM for the candidates research talk. 4:30-5:30 for the wine and cheese reception. A 90-minute block for a campus tour which ends with a meeting with the Dean (check with the Dean on availability). He contacts the other members of the department and allows them to schedule 30 minute meetings with the candidate for any time slot not yet taken and to join meals. Slide 20 Exercise Consider the general task of voting A voter chooses one (or more) candidate from a set of candidates for a particular office In a given election, voters may have to make choices for multiple offices Slide 21 Exercise Part 2 Now consider tasks Write 2 task descriptions Who are the users? What are they trying to do? Slide 22 Some example tasks Casting a vote Changing a vote Casting a ballot Counting votes Recounting votes Slide 23 A better task description Mary Lee Rollalong gets a ballot. She votes for: Jay Walker for Mayor Krystal Ball, Moe Cotton and Jim Lawless for City Council Bob Shotwell for Sheriff She then realizes she can only vote for two city council members and so she unvotes for Moe Cotton She submits her ballot. Slide 24 Scenarios Specific instances of system use From the what to the how A particular task A particular interface What the user do would, in detail enough detail for a user to complete without task knowledge Slide 25 Example Scenario Open two command prompt windows. In window #1 type ls l In window #2 type pico news.ord Type the following items one per line stokeef.xy stguns.xy stvet.xy stwres.xy stcomp.sy. Slide 26 Example Scenario Using the cursor keys, move the cursor after the y in the line reading stvet.xy. Type >lead. Using the cursor keys, move the cursor to the line reading stwres.xy Press ctrl-k to delete this line. Press ctrl-x followed by y to save this file. Type pico sports.ord At the end of this file type stwres.xy Press ctrl-x followed by y to save this file. Slide 27 Scenarios arent always computer related Obtain a paper copy of the visitor schedule sheet from the secretary. In the who field write Sal Lammy. In the when field write February 7 th. In the why field write job interview. Draw a box around the fields for 12:00 and 12:30. Inside this box write Lunch with Li and others. Draw a box around the fields for 6:00-8:00. Inside this box write Dinner with Wenthold and others. Pick up the phone and dial 3-1234. Find out what time in the morning the Dean would like to meet the candidate. Draw a box around the time field suggested by the Dean and the hour prior to this. Label the box tour and visit with Dean. Slide 28 Properties of Scenarios Interface-dependent Detail appropriate to user, task, interface Make certain issues obvious how components work together tricky parts of the interface First step in evaluation Slide 29 Exercise Take a look at myUNIverse.uni.edu Define 3 tasks students might try to accomplish with the site Remember what tasks are used for Slide 30 Where are we? Project This week in Studio First user visit during week Visit Report due Friday Reading Should have read DOET TCUID 1-2 Slide 31 Hey wait!!!! Werent we supposed to have some pop quizzes from time to time??? Put everything away except a pen/pencil.
