After interviewed with 6 analysts, here are the user requirements I gathered.
Requirement 1 : Depending on the tasks, different analysts have different opinions on what is an important feature for them. For instance, sometimes one variable is more important than another depending on the field operational task and/or risk environment.
Requirement 2: The data from the group and from individuals are both important to view. For instance, if the average data from the group is abnormal, it is more likely to be caused by something in the environment rather than an individual-based health-related problem.
Requirement 3 : How the alerts are triggered is very important. The analysts’ mission is to protect the workers in the field, so they don’t want to miss any potential risk. However, too many false positives could potentially confound real alerts. Therefore, giving the analysts a certain degree of control on the alert settings is the key.
Requirement 4 : As the data is updated in real time, the ability to rewind, mark, and revisit the historic data and alerts is required.
The Process
Skeches
One of the ideas. The user feedback was the visualization is complicated and hard to follow.
The idea that the user preferred. The main reason is the visualization is very straight forward and easy to follow.
High fidelity design
First iteration
The team thoughts it's too complicated to develop with the tight timeline we had.
The final design
Greatly simplified the visualization. Heavily using color to indicate the threat level. The analyst can know who is at danger at a glimpse.
