US Patent 9293024 Sitting posture detection and reminder mechanism for a toilet

Systems and methods are provided for detecting a sitting posture of a user on toilet and generating notifications for the user based on the detected sitting posture. A sitting posture detection and reminder mechanism measures a distance X between a distance sensor and a body of the user sitting on the toilet. The mechanism calculates an angle α between the user's spine and the user's thighs based on the measured distance X and generates a sitting posture notification for the user based on the calculated angle α. The mechanism may operate a motor coupled to the toilet cover to automatically adjust an angle of the cover and guide the user into a healthy sitting posture.
