Role

Design a user-experience aimed at increasing awareness and accessibility of real-time water quality information across a university campus. HydroPace addresses the critical issue of water quality on university campuses by developing a real-time water quality awareness system. Recognizing the reliance on water coolers, the project integrates physical and digital elements, providing instantaneous information.

Project Overview

Collaboration with:

Limited awareness about the safety of drinking water!!

The Challenge:

To increase awareness and accessibility of real-time water quality information across a university campus.

Contribute to the overall well-being of students, faculty, and staff by addressing the critical concern of water quality on university campuses

To mitigate potential health risks associated with the consumption of unsafe water.

Goals 🎯:

Our initial research methods include surveys for quantitative insights and user interviews for qualitative depth. We use a structured questionnaire to delve into participants' experiences and concerns. We emphasized a "think out loud" approach. The questions covered water usage, awareness, technology preferences, and app features, ensuring a holistic understanding.

Research:

72 million

Number of people in the US who are affected by water borne diseases.

15,000

Number of students and staff at Pace University.

91 miles

Distance travelled by the water from the reservoirs to the campus.

Insights From Users:

01 Participants highly value water quality, mainly judging it based on taste and clarity.
 

02 Primary challenges include slow dispensing fountains, health concerns related to water coolers, and navigation issues accessing coolers.
 

03 Participants usually trust university standards and rely heavily on word-of-mouth for their water needs on campus.

Initial Concept:
Water fountain will include water quality status indicator light, feedback button, and NFC tags that link to web-app.

The web-app will show the floor map, which indicate water cooler location and status as well as water quality information educational articles.

Ideation:

MVP

We created the MVP of physical concept of water cooler by employ a Red/Yellow/Green light indicating the quality of water and state of the cooler, along with mock NFC Tags and repair-me button.

Unassigned tasks targeted 22 incidental participants interacting with the physical prototype on campus.

The test focused on testing the intuitiveness of the physical prototype, observing user behavior towards indicator lights, mock NFC tags, and a mock 'Repair-Me' button. This unstructured task aimed to capture natural user interactions with the physical elements, providing insights into the use of system-status indicators, attempts to access additional information via NFC tags, and attention to physical signage.

The concept integrates prominent features, such as physical water cooler indicators, including indicator lights and visual signals, aimed at providing immediate feedback on water quality. The incorporation of crowd-sourced feedback through NFC tags encourages user participation and allows for efficient issue reporting. Simultaneously, digital water quality information, facilitated by NFC tags and comprehensive data display, offers users detailed insights.

Physical Prototype

Users

15

Our team conducted a comprehensive field study at Pace University's 15 Beekman Street, focusing on bustling floors 1, 6, and 9. The primary objective was to evaluate user interactions with both physical and digital prototypes, aiming to assess their effectiveness and user acceptance.

Usability Testing

Tasks

Success Rate

86%

We set up our prototype for the field test at Pace University’s 15 Beekman Street building.

We performed our Usability Test from a pool of participants that consisted of students and staff. With a combined set of diverse backgrounds and unique opinions, we felt we were able to gather very valuable data across the spectrum of all our potential users.

Identify measurable metrics representing quantitative data obtained from usability testing across all four tasks.

Task 1: Approach the water cooler as you would usually. Please observe the color of the light and let us know what you interpret from it.

Task 2: Let’s say you have just used the cooler to fill up your bottle and encountered an issue with the taste of the water and its appearance. You want to notify the system of this issue.
 
Task 3: Let’s say that you have just approached a water cooler station. You want to know whether the water being dispensed is safe for consumption or not before you fill your bottle.
 
Task 4: Let’s say you're on the 4th floor of 15 Beekman Street and are trying to find the water coolers on that floor. You notice the ‘Drinking-water’ signage right in front of the elevators.

Usability Testing Results

Key Findings:

Iterations:

Building on the insights gained from the generative study, usability testing, and field testing, HydroPace's water quality awareness system can undergo targeted refinements to enhance its overall effectiveness.
1. Incorporate smaller indicator light to avoid glare
2. Avoid technical terms to convey Water Quality Information
3. Clearer symbols and additional guidelines for steps to provide feedback about the cooler quality
4. Preference of QR codes over NFC tags

Next Steps

🌼 Using Literature Review for Exploration
The literature review served as a crucial foundation for exploring and understanding the area of real-time water quality monitoring on university campuses. It provided valuable insights, best practices, and existing solutions that informed the design and implementation of HydroPace.

☁️ Not everyone has the same level of technological proficiency
The importance of simplicity in app navigation cannot be overstated. Designing user interfaces that are intuitive and easy to navigate is paramount. HydroPace's emphasis on user-centric design and usability testing helped identify areas for improvement in app navigation, ultimately enhancing user experience and accessibility.

☀️ Value of Usability Testing Despite Time Consumption
While usability testing can be time-consuming, the investment is justified by the invaluable insights gained. Conducting usability tests multiple times allowed the HydroPace team to uncover user preferences, pain points, and areas needing refinement. This iterative approach ultimately led to a more polished and user-friendly solution, showcasing the importance of thorough testing and refinement in product development.
