Session Two, Question Three: What were your likes and dislikes with your
second exposure to DaViTo?
Like: Intuitive to use select a specific area and use shapes to draw graphs. The
different options to modify plots (e.g. - freq vs percent- normalized- etc.)
Dislike: Since there is an inherent lag in the system- a user feedback prompt or inprogress bar would be helpful to the user. Inability to change the line colors in the
plots
Likes: Reviewed previous Session- so that quickly got me reoriented to the tool.
Gained knowledge on the system to include informational/Statistical plots. Focused
was on the different views and map manipulation.
Likes: Clear instructions- good examples of tasks. Hands on is definitely a benefit to
learning the application rather than just watching the video.
Dislike: Is really my personal preference to see the instructions while I'm executing
the task. Since I don't consider myself to be proficient with this software yet- I'd like
the option to refer to the question you're asking as I go down the menus (to confirm I
understand the task).
Like: Step by step instructions
Dislike: Need to memorize each step of task (the white screen) and no able to go back
to reread the instruction.
Dislikes: Still a little difficult to remember how to load data set. May have been to the
brief exposure.
Likes: Ease of general statistical analysis- access to overlays- ability to create new
graphs on the fly.
Dislikes: Response times to clicks- load times for data sets- unclear chart option
explanations in control panel- too many steps to draw a shape.
Like: The ability to create the chart in order to pull data.
Dislike: Remembering the steps to create the chart.
Dislikes: The maps take a while to upload- seems okay for this environment but it may
be too restrictive in a real work environment that requires more changing- uploading
Dislikes: Maps and charts loaded a little slow- but other than that no issues.
Likes: Good graphical user interface- and the pop-up menus were easy to follow.
Graph displays were good. No dislikes with my second exposure.
Likes: Visual interface
Dislike: Area selection method
Dislikes: Deeper you go into the functionality the more you have to remember. Tough
to do when you get older and your short term memory begins to slip.
