Context

With more and more applications and other forms of entertainment available on smartphones today, more and more people are carrying their phones when they go to the bathroom and spend way more time than needed on the toilet. This causes a lot of inconvenience to others, especially if the bathroom is shared.

Conceptual Design

This device notifies people when they spend more than a specified amount of time on the toilet by using a light and speaker system installed in the bathroom. The light gradually changes color from green to red over a period of 10 minutes, which allows the user to keep track of time. When the light turns red a speaker system starts playing a song which only stops if the user gets off the seat. The device also sends the user a notification on a phone as a warning. This encourages people to vacate the toilet as soon as they are finished using it.
