9 weeks at Enovation Controls: a Helios Company: conducting usability research, heuristic analysis, and UX recommendations for hot tub, marine, and off-road vehicle displays.
Enovation Controls is a leading innovator in the field of electronic controls and displays. They specialize in providing customized solutions for engines, engine-driven equipment, and specialty vehicles.
With a reputation for cutting-edge technology and problem-solving expertise, Enovation Controls serves niche markets by delivering integrated solutions that go beyond convention. They prioritize core values, empower their employees, and aim to make a positive impact on their customers' success.
Across 9 weeks, I contributed to six distinct client projects spanning hot tubs, speedboats, off-road vehicles, simulators, and marine apps.
Conduct user testing for SpaTouch 3 and 4 to find out issues and provide suggestions for future products.
Design usability issues of the interfaces and provide suggestions for the Supra MY24 speedboat display.
Redesign high-fidelity mockups based on client feedback received.
Design Search Trail and Trim track features and improve the UX of the current system.
Design a simulator testing system used by Enovation's internal development team.
Conceptualize and wireframe a waves app that integrates with boats in real-time.
Balboa Spa Touch is a top-quality hot tub control panel with reliable Piezo electronic switch technology and moisture protection, making it a durable and dependable choice for the spa.
My Responsibility: Identify usability issues in Spa Touch 3 and Spa Touch 4 displays, and offer user experience recommendations to enhance the usability of the Spa Touch 4 Display (to be released to market).
The project's objective was to identify usability issues and offer recommendations for enhancing the upcoming product's functionality. I focused on refining the product's user-friendliness and efficiency.
An 8-week structured process from understanding the problem to presenting actionable UX recommendations.
Before conducting user interviews to gather insights into ST3 and ST4, my initial step involved identifying the user interface and user experience issues within these products. This preliminary assessment allowed me to become well acquainted with the existing problems and features, enabling me to engage with users more effectively during the interview process.
Conducted 16 user interviews across departments and age groups within Enovation Controls. To ensure integrity and minimize potential bias, interviews were segmented into different study sequences.
I conducted interviews lasting approximately 30 to 45 minutes, during which I divided the studies into various tasks. I asked participants to complete these tasks while recording the time it took them to do so.
I've created interaction maps for both ST3 and ST4. Upon analysis, I've observed that the interaction flow in ST3 appears to be more complex, with multiple interactions requiring more than two clicks. In contrast, ST4 exhibits a more streamlined and organized interface, characterized by interactions that typically involve just two clicks.
Following the completion of all interviews and gathering user feedback on ST3 and ST4, I meticulously documented the positive aspects, identified pain points, and collected suggestions from participants.
I then organized these suggestions into distinct feature sets, color-coded them for clarity, and conducted a comprehensive analysis of the identified issues.
After conducting all interviews, I jotted down all the positive and negative points received from each participant: capturing both what worked and what needed improvement.
"I am confused between the different names and settings of the lights. No idea about different light names."
"I love the command and fluidity of ST4 and the Air Features is really cool."
"The filter cycle time and change time scrolls doesn't start from the current set time, it's unreliable, they always start from 0:00."
"The jet speed design is intuitive. I like the icon wider spreading illustration."
"I'm using the system for the first time, I wouldn't know what the icons on the top indicate."
After each interview, I provided the System Usability Scale form to all users and asked them to provide feedback by giving the scores for all 10 questions for both ST3 and ST4.
After calculating the average score both ST3 and ST4 lie in the Marginal range: providing a clear baseline for improvement recommendations.
After analyzing the issues and in order to increase the efficiency and score of upcoming ST4 launch, I performed a heuristic analysis on the gathered information. It was essential to gain an in-depth understanding of the issues that users encountered while interacting with the systems so I can help pinpoint areas in which improvements are needed.
