What is Node?
By visualizing the data coherently on time lines and maps, the design makes complex processes and vast amounts of data, currently scattered in a multitude of formats, more legible and easier to relate. This creates a faster, smarter and more efficient workflow.
NODE is an intelligent system, which uses data gathered in past cases and from other sources to enable predictive and assistive functions. These functions help dispatchers gather important information to base their decisions on.
Before & After Screens
Due to confidentiality the original data has been removed.
User Research & Analysis
The first two weeks of the project were dedicated to research. We went to the LKC twice, first with the entire class for an introduction, and a second time in smaller teams on four hour shifts.
We observed the work environment, and the way the dispatchers use the interface to communicate, report , and search for information. We interviewed them on their experience in quieter moments and took photographs, video- and audio- footage. After these visits, we analyzed what we had seen and developed our areas of interest.
Multitude of information channels
They have 8 different databases for searching different types of information.
Visual hierarchy does not reflect hierarchy of use
The sizes of windows, such as address book or sound control, do not reflect the importance, regularity or order of use.
Relating information is difficult
Functions used together are often spaced far apart in the layout. Textual codes for resources are difficult to recognize in lists.
Smart work flow
From our observations we saw that there were multitude layers of information on cases and resources scattered all over the system and there was no coherency in the interface or synchronism in the workflow.
We realised that an enormous amount of crucial data is generated with every case, but is being underutilised by the system for smarter working on future cases.
Time is vital to the system. All information is time-tagged and time is indicated in various windows in the interface - it is the underlying structure of everything. However, there is no coherent display or visualization of time. We decided to put our main focus onto that.
Based on our discoveries, we started brainstorming ideas, sketching, discussing and building simple, interactive prototypes in paper and initial graphical details using 2-D softwares.
We got input and feedback on our concepts from LKC staff on two occasions: a Co-design workshop and a user testing session.
The overall concept to display activities with icons on a time line was very quickly understood by all three groups and got a positive feedback. They liked the idea of browsing collected information, especially for data searches.
