Proportional Timeline Visualization

Body Camera Activity Log (Audit Trail)

Developed while Product Design Intern at Axon - Summer 2017

 

Axon's body cameras log every user action into Audit Trails which are used in investigations and as evidence in court to establish ground truth.

I redesigned Axon's audit trails to be interactive + clearly surveyable by identifying the central concern, the proportional representation of time.


Prior to my internship at Axon, audit trails were raw spreadsheet tables:

These are in-office test actions, not real data from the field.

 

Their form made quick understanding difficult. The relative timing of events was obscured because each entry occupied the same vertical space — entries a second apart appeared as close as entries a day apart.

 
 

Displaying time proportionately
reflects + preserves the pacing of events.
