The main screen shows a list of available channels and color codes them based on recent activity. Tapping a channel selects its detailed view (bottom right) which displays live graphs of any numeric quantities. Tapping a graph or number in a channel brings up the graph interface (below).

More traces can be added to the plot by pressing Menu and then selecting Add Trace. The Add Trace window appears (lower right) which allows the user to browse through available channels and variables in those channels. More than one new variable can be selected.

Graph screen (cont.)

When graphing text, we display small colored bars at the bottom of the screen that change color when the text changes. While this does not convey what the text is, it conveys that it has changed, which may still be useful. We use a hashing strategy to display colors, so that the same text will always have the same color.

Control mode

A control mode, accessible from the Menu button on the main screen allows the user to change parameters. Options are presented as spinners which update in real-time (send data on finger-up). An interface for selecting the resolution of the spinner is shown in the lower right.

Analysis

• Learnability
  • Most things are clickable in this interface, so learnability should be relatively easy. The graph mode has a few features that novice users are not likely to know about, but that is more a visibility issue.
• Visibility
  • Some options like the command menu are accessible only from the Menu option, which might cause visibility issues. This issue arises for some of the graphing screen's more advanced features as well.
  • Most data is displayed early and quickly, so data visibility is high.
• Efficiency
  • The drill-down aspect of the interface may not be the most efficient, but we expect that it is worth the organizational and learnability benefits.
• Error Prevention
  • The only serious errors that can occur with the application is in the command screen. As the interface stands, commands are sent on finger-up, but if testing reveals that this is an issue, we will likely add a Confirm button.
