Capturing toilet behaviour for real-time data and health analysis.

Quantified Toilets was a thought experiment brought to you through the Critical Making Hackathon by: Matt Dalton (SFU), Angela Gabereau (Fabule Fabrications, Inc.), Sarah Gallacher (UCL), Lisa Koeman (UCL), David H. Nguyen (Nokia) and Larissa Pschetz (University of Edinburgh).

The response has been overwhelming and we are curious to know your thoughts. What did you think of Quantified Toilets?

At Quantified Toilets, we work with local businesses, building owners, and local officials to improve the health and efficiency of individual buildings, neighborhoods, and entire cities. We are focused on you and your community.

We are proud to be a part of Toronto's Healthy Building Initiative, and are excited to deploy a preliminary infrastructure throughout the city’s major civic structures. Along with our partners, we leverage big data collected from the everyday activity of buildings and their occupants. Admittedly not the sexiest of data sources, we analyze the biological waste process of buildings to make better spaces and happier people. We use this data to streamline cleaning crew schedules, inform municipalities of the usage of resources, and help buildings and cities plan for healthier and happier citizens.

Using advanced sensing technologies and a state of the art centralized waste data collection system, we are able to discreetly capture data from each individual toilet. Activities at each toilet create unique signatures that enables us to track usage and analyze details from every toilet in a building. Our groundbreaking software is then able to catalog the data for a multifaceted health analysis not currently available through traditional means.

We are able to accomplish this analysis inexpensively because entire buildings can be analyzed using very few sensors placed at strategic locations. Due to this cost reduction, we are able to analyze every usage, every day, and every time. Something traditional testing services simply cannot do.

As we refine and advance our technologies, our goal is to serve people with individualized analysis, allowing everyone the ability to access and track their health data whenever and wherever they want.
