Tooshlights is an IOT Technology that pairs a smart latch and an indicator light, specifically created to improve the bathroom experience by reducing wait time and guiding patrons to the next available restroom stall. 


User Need

  • Design a restroom analytics dashboard for facility managers, that would prioritize providing them with useful insights faster.

Business Goal

  • Drive additional revenue


I was able to create personas and prioritize the features of the dashboard through interviews. Prior to this, I had no clue what a facility managers job involved and what their needs or pain points were. Speaking with them individually helped me understand the deeper details and how this dashboard would help address some of these key issues

Primary Persona

Use Cases

The dashboard also has an impact on other groups, such as employees and stakeholders who are indirect beneficiaries of it. To analyze the user's needs from their angle, I created use cases and indentified how features could help them.

Feature Prioritization

The exercise of interviewing facility managers provided important details which I then translated into user needs as follows-

  As a user I should:

  • Be able to toggle between different incoming data for each facility

  • Know the status of all stalls

  • Have a visual representation for the layout of each facility

  • A visual representation of the data for each facility

  • Have the ability to control sensory light settings

  • Have the ability to control battery settings

Prototype and Usability Testing

I created initial feature sketches and wireframes which I converted into a clickable prototype. Clients were presented with the prototype as a means of validating that we had covered all the use cases.

After validating that all the use cases have been designed for during the prototype testing, the final wireframes were tested for usability to ensure the UX is intuitive.

Exploring Data Visualization

I presented facility managers with a set of "data visualization cards" for concept testing. The goal at this stage was to validate which views of the data would be most useful and immediately understandable. I ultimately moved forward with an area chart design. It  better depicted to the user,  a time-series relationship between the number of bathroom usage and the activity per day.  

High Fidelity Designs

 I used different techniques like color, typography and layout to emphasize importance, and draw the user’s eye straight to the thing(s) that need immediate attention. The use of bold, and meaningful color tells the user/facility managers something important in a split-second (number of stalls open vs. closed, patterns of use etc.)—something that might otherwise have taken close to an hour to decipher.
