Open source software tracking orca vocals to advance marine conservation awareness

Timeline: March 2021

I streamlined Orcasound's reporting flow to simplify user submission of orca sighting reports, aiming to increase engagement and gather crucial conservation data. Working with a global team of designers, I conducted user research, redesigned the interface based on user feedack, and performed two rounds of usability testing.

How can we effectively address these conservation issues through our design approach, while also enhancing data collection to support the protection of the species?

I increased the task completion rate by 15% through the implementation of improved designs baed on user insights.

Defining the problem

For conservationists, there is very little knowledge about orca vocalizationmaking it hard to encourage the public to help participate in conservation efforts. Currently, there are no existing educational platforms that teach people how to identify the sounds of the southern residents.Our overarching objective is to create a comprehensive solution that caters to these diverse needs, closing the knowledge gap surrounding orca vocalization, and mobilizing a broader community to actively contribute to the preservation of these remarkable creatures.

The Existing Process

The existing Orcasound mobile app represents a straightforward and functional tool created by the collaborative efforts of a global community of dedicated volunteer developers. To gain a better understanding of its functionalities and identify areas for potential enhancement, I conducted a thorough analysis of the current Orcasound app, highlighting both its strengths and areas of improvements.

Testing the first re-design iteration with citizen scientists

I joined the Orcasound redesign project during the critical testing phase for the first prototype iteration. To evaluate usability and user experience, we conducted virtual moderated usability tests, measuring task completion rate and collecting System Usability Scale (SUS) scores.

I conducted 5 usability testing across a diverse participant group:

  • Ages ranged from 40-65, spanning key user demographics
  • Participants matched relevant personas: concerned citizens, new users, scientists and educators

This range of qualitative and quantitative data provided valuable insights into how well the redesigned flow resonated across user groups. The data gathered was essential for optimizing the experience and tailoring it to our users' needs and goals.

What are the Pain Points?

By synthesizing the findings from our usability tests, I generated key insights into user pain points. I presented these insights to our core stakeholders in an affinity diagram that mapped out users' qualitative feedback. In particular, I grouped together common frustrations citizens scientists encountered with the report a sound flow:

“Where do I start listing to the orcas?” Citizen scientists were confused on how to initially access and listen to the hydrophones. They expected a clear "start listening" button.


“Moving around this map is difficult” Older users had difficulty navigating the map on their small screens to access different hydrophones, which often led older users to abandon the process

“That took such a long time” New users noted reporting sounds involved too many steps. Users expected a single screen and the ability to report multiple sounds simultaneously.

SUS Score from the first usability test (above average but could be better)

There were three major pain points that I decided was important to address in our next iteration


The navigation bar was untraditional and users were confused by it. Most could not get back to the home page.


Having users drag the map around to search for hydrophones was inefficient and troublesome.


There were too many unnecessary screens to complete the report a sound task.

Testing a Possible Solution

Based on the user feedback compiled from the first test, my design group and I made some improvements to the existing design to test with users.

Home Page

  • New navigation bar and color to match the button colors
  • Added a home icon to give users a more familiar layout
  • Full width image at the top instead of just in the corner in order to excite users more

Map UI

  • Added a clear “Start Listening” call-to-action button on the home page
  • Simplified the hydrophone map UI for easier navigation
  • Under the nav bar tab “hydrophone” so users know exactly where they are

Reporting a Sound

  • Condensed the reporting flor from 5 screens down to 3

Testing round 2

Once we improved the design based on the first round of user feedback, we ran a second usability study with the new and improved experience. Again, we were looking for task completion rate and and increase in SUS scores.

Final Hi-Fi Design (My Revisions)

Although we increased task completion and SUS scores, I saw room for refinements like enhancing the map UI for older users and streamlining the reporting flow. The following prototypes represent the research, iterative design, and testing that was crucial to validating my solutions.

Orcasound strives to foster broad engagement in marine conservation, regardless of location. We aim to provide an accessible platform that enables simple participation, sparking curiosity about conservation in people of all ages.

Hydrophone Flow

Driving orca discovery through enhanced movement

The latest user interface comprises an interactive map that seamlessly directs users to select a hydrophone with heightened visual and dynamic features. Each hydrophone site showcases an image and clear instructions for orca listening, thereby promoting exploration, enhancing guidance, and ultimately increasing the number of listeners.

Reporting a Sound

Increasing orca numbers with a better experience

We crafted a reporting flow that incorporates detailed information about the hydrophone, a play button with sound waves, and a clear signifier to confirm the success of the report. This flow has greatly improved the reporting experience by ensuring seamless functionality, while preserving the integrity of the original design.

Impact and reflection

Orcasound has been an incredible opportunity allowing me to blend my background as a marine mammal population specialist along with newly developed UX design skills, allowing me to produce a design that I am incredibly proud of. I greatly enjoyed engaging users through usability studies to shape objectives and strategy, synthesizing findings, and collaborating with other designers to produce our strongest ideas.
