Challenges
1. Speed
Every second counts when someone is in cardiac arrest. Designing a quick UX was our number one priority.
2. Simplicity
Being in a panicked state can lead to mistakes, so ensuring the UX & UI are simple and easy-to-follow was critical.
The UX at a Glance
Two figures
• The individual in cardiac arrest
• The individual using the AED
High color contrast of the most important elements
The Team
• Industrial designers
• UX & UI designers (me)
• Usability engineers
• Mechanical engineers
• Electronic engineers
• Prototype functional testers
The Process
The UX team collaborated hand-in-hand with the industrial designers, changing up concepts as the physical device changed.
UX Challenge
Due to the UI being backlit LEDs, none of the UI elements could overlap, causing us to get creative and meticulous with the layout and placement from concept to concept.
Design Solution
None of the dynamic UI elements overlap, allowing room for each step.
Our final prototype efficiently walks the user through the process outlined above.
Expedited run-through of the steps. The actual version is significantly slower, with voice commands for each step.
