OUTCOME
A radical change in the UI as a result of improving the I.A and layout of toolbars, resulted in 0 mild to moderate usability issues within a group of 3 users over 6 clinical procedures.
WHY - PROBLEM SPACE
“As an electrophysiologist I do not want to be distracted by tools around the data and the software operator’s mouse movements.”

WHAT - THE GOAL
creating a scalable design
which prioritizes procedural data and
minimizes mouse movements
INFORMATION ARCHITECTURE
scalable design
HIERARCHY OF INFORMATION
11% increase of the physician’s view
Discoverability is not a principle for this product as users undergo extensive training before they use the product in the field. Driven by users workflow and frequency of the use of controls I utilized UI design elements to create a layered architecture including:
-
eliminating duplicated controls by defining the scope of their effects - panel specific or global (across panels)
-
expandable and collapsible menus
-
tabbing structure
-
including a ‘more options’ button

F SHAPED PATTERN OF READING
restricting mouse movements
The highlighted F-zone of the interface is clear of frequently used controls, thus restricting mouse movements in that area. This further emphasizes the procedural data.
“Use the F-shaped pattern to draw attention to the most important information instead of relying on the arbitrary elements that people may fixate on when they scan in an F-shape.”

HOW - RELEVANT RESEARCH
research backed design
COMPETITIVE ANALYSIS
optimizing screen real estate
Considering that the software is not a web based product and is used in a highly niche context, we had to rely on how our competitors handled certain features and their design.
competitor 1 - 85% procedural data
competitor 2 - 90% procedural data
Kardium’s previous Globe software - 75% to procedural data
FORWARD THINKING
offering multiple concepts
In an agile software team which values incremental improvement over perfect solutions, I aimed to provide two or more design solutions with varying degrees of usability, value and feasibility.
1. today - cheap and cheerful solution
2. tomorrow - more sophisticated, target solution
USER ENGAGEMENTS
context specific testing
At Kardium, I have experienced testing in different contexts depending on the stage of the design process. This includes early UX engagement, Usability testing and Simulated testing.

ENDORSEMENT
KEY STAKEHOLDER - CEO
It reminds me of a Tesla's interface now - the nested architecture and modern look.
KEY STAKEHOLDER - DIRECTOR OF PRODUCT
The menus are much more usable and contemporary. The toolbar is more intuitive and accessible. Makes a lot more sense, fewer clicks and invisible which is great.
KEY STAKEHOLDER - CLINICAL FIELD SPECIALIST
It was really slick in the demos. Even better than I expected.
