SWE 4783 WEB B Web B is the experience of participating in a semiotic exploration from Ch. 1 of your textbook. This experience is target for Week 3 of Fall 2014 To be done instead of the Thursday’s 8/28 class
Treemaps • Read Ch. 1 especially p. 10 – 23 • The author used Acrobat 5.0.5 to document the design of UCD cannons and the problems with the absence of introducing the new technology. • Look over the following PP slides • Do the semiotic scoring experience by: • Download treemaps tool • Record your experience using treemaps with 2 different data files • Create your report file something like your textbooks accounting of Acrobat’s problem (so explain and use screen shots). • Hand in your report file with your some of your raw data, your analysis, and your informational graph as WEB Bby Monday 9/1 midnight.
Semiotic Scoring Experience • You are the user of a Visual Organization tool called Treemaps. • You have been asked to use the tool and score it according to your understanding of the tool.
First download & Install Treemaps Please go to http://www.cs.umd.edu/hcil/treemap/ to install the software tool. Run the software and open the simple1 data file. You should see the following slide.
The First Impression Please record (audio) your experience so that you have the true original experience for you to refer to in your analysis. Speak out loud at the items you are looking at (without mouse travel or keyboard interaction). Tell us what you think they are in detail. Now spend another minute exploring with the mouse/keyboard with a verbal explanation of what you are doing and noticing. Please give out loud any associations, assumptions, understandings.
The Experience • Explore the software to discover: • Operation – What can you “do”…. • Controls – What can you “change” … • Feedback - Does the system “tell” you …. Please remember to think out loud - record your experience.
Specific Tasks in Simple1 • In case you changed the tool in your exploration, please restore default. • Find the label “Roads” on the top of the treemap (and select it with your mouse). What do you notice in the top right window? How many nodes? • Place your cursor on I-234. Notice the top right window with data. • Go to the second window and change the tab to Legend – change the size and color to speed limit
Open different data file • Please go to File and open the census.tm3 file • Operation – What can you “do”…. • Controls – What can you “change” … • Feedback - Does the system “tell” you …. Please remember to think out loud - record your experience.
Specific Tasks in Census • In case you changed the tool in your exploration, please restore default. • Notice the labels on the top of this treemap(and select each with your mouse). What do you notice in the top right window? How many nodes for the different labels? • Place your cursor on the different “Agricultures”. Notice the top right window with data. • Go to the second window and change to the tab “Legend” – change the size and color to “Establishments”. Now change color to year.
Experiment Done • You are done as a user. Now you are a usability evaluator. • You have the audio recording as the data and metrics that were gathered. • Document your experience in an outline of what was done. Keep it simple by giving a list of the explored areas. You can give different groups (understood items), (not understood items) etc. • After you document your experience, look at the following slides for a reading of the usability of the treemapapplication with regards to whether it had usability “cannons”. UCD cannons are Usability good practices. So address whether Treemaps did the good practices.
For this section – please give where you saw treemaps give evidence or where treemaps didn’t give evidence of: Offer information feedback (did you seetreemaps give you evidence of what the system was doing) Visibility of system status Lack of data entry instructions? Lack of clear indication of status? Lack of search in progress? System and real world Use of …………. as menu headers Use of …………. as menu items Lack of ability to ……….. User control and freedom Was the dialog designed to yield closure? Support internal locus of control? Breadcrumbs …. Back feature (undo) … Type an accounting of the following UCD Cannons when used with the treemap application
Strive for Consistency (standards) Data arranged Consistent template Error prevention offered error prevention and simple error handling? Permit easy reversal of actions? Recognize and recover from errors Aesthetic and minimalist design Recognition rather than recall Reduce short-term memory load Help and documentation Continuation of examining the UCD Cannons
Web AB was simple experience with one user (you) to uncover whether the tool communicated the design vision. Please review your report for both the original impressions of Treemaps and the evaluation of Treemaps as containing the “good usability practices”. You will upload a report of the simple experience with the data collected into D2L. Please give the raw data and then take the raw data and organize it to show a premise.
