UX TESTING AND RESEARCH

Life or Death UX

Every so often, we take on the responsibility of leading a project with life or death implications. Take, for example, the work we’ve done for Logos Imaging, designing and building software that runs portable inspection systems for bomb techs.

The basics of usability, listed below, take on a new level of importance in this domain.

Simplicity – Is the experience as simple as possible and tailored to the task at hand?

Affordance – Do the controls map to the result in a simple and logical way that is easily determined at a glance?

Feedback – Is it clear what is happening/what has happened?

Structure – Are features organized sensibly and clearly?

Consistency – Are the design patterns and language consistent throughout?

Tolerance – Does the application provide easy reversal of actions and/or the ability to recover from errors?

Accessibility – Is the application usable by all intended users on their desired device and/or environmental conditions?

Sometimes In Situ User Research is a Really Bad Idea

Embracing the tenants of user-centered design, we often conduct research in situ with the people we’re designing for. Contextual inquiry allows us to gain a true understanding of the tasks users aim to complete, along with the constraints of their work space. But it’s generally a bad idea to shadow bomb techs, and ask them questions as they’re working. So on this project, we instead relied heavily on event simulations and interviews with retired bomb techs.  

Drawing on findings, we defined a corpus of mission-critical features, expressed as user stories, to inform our interaction design work, and deliver on bomb techs’ needs through a best-in-class application, LIA 8. We found that although the existing application, LIA 7, had a robust feature set, its dense UI hindered usability. Through our research, we developed an understanding of what features techs used most often in LIA 7 and which were hardly used (80/20 rule). This allowed us to clean up the UI substantially.

Building for Bomb Squads

With the new application, we utilized PHP, HTML, CSS, and Javascript (with a heavy focus on the Javascript Canvas element) to create an image manipulation tool that works across devices. Our custom Javascript Canvas matrix is able to track user actions, apply adjustments and transformations to the image in real time, create beautiful histograms, and then categorize that image into organizable incidents. The software even provides a native touch interface built on the Universal Windows Platform, customized for use with fat-fingered bomb-tech gloves.

Mitigating Risk

The business case for investing in user-centered design often revolves around driving increased revenue through better conversion and retention rates, or reducing costs by achieving greater efficiencies and higher levels of customer self-service. But this project was all about reducing risk by providing greater visibility of potential threats allowing the technician to focus purely on the task at hand. Helping bomb squads save lives is not only some of the most rewarding work we do, it’s also a major crowd pleaser during career day at school.
