Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to test an electronic apparatus for measuring stool and urine output in an accurate and easy way. Participants will have one in-person or virtual visit with the study team prior to starting the study events. Participants that enroll in this study will have the freedom to choose when to begin and stop using the toilet apparatus when it is available for human testing. This apparatus will be located in a private bathroom in either the CIEMAS building or MSRB III Building.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

apparatus use

All participants will use the apparatus following the same procedures. They will weigh themselves on a scale located in the bathroom, use the apparatus with or without "hats" ("hats" refer to a plastic container used to catch stool/urine that needs to be placed between the toilet rim and the toilet seat and discarded after each use) and weigh themselves after using the toilet.

Group Type EXPERIMENTAL

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* people who are able to use the private bathroom at no risk to themselves in the CIEMAS building (B508) or the bathroom located in room 4002, 4th floor of MSRB3.
* students or employees at Duke University since card access is required for our MSRB3 bathroom.
* people who spend most of their time in these buildings so we can assure the use of the toilet.
* If the recruitment number is slow, enrollment will include people from the closest buildings.

Exclusion Criteria

* People who use wheelchairs or other mobility devices won't be able to enroll, since at this moment the bathroom is not compliant with the requirements on The Americans with Disabilities Act (ADA) of 1990.
