Posture Care is a chair cover that monitors employees’ posture to improve workerproductivity by reducing the frequency of posture related injuries. With Posture Care,information is sent in real time so individuals can correct posture issues before theyoccur. This system benefits employees by improving health and preventing injuries. Thisposture monitoring system respects employee privacy in ways a camera-based systemcannot. A summary of how Posture Care works is shown below.

How Posture Care Works Sensor Locations

Posture Care uses an Arduino to determine posture from sensor data. To demonstratethat Posture Care works, posture data was sent using a bluetooth module to an Androidphone. An Android application was used to display user posture and the relative amountof time spent in each position. This method, along with the detectable positions areshown on the next page.

A small breadboard and Arduino contained all the circuitry necessary for one bluetoothmodule, two force sensors, one distance sensor (see picture below). The force sensorswere sewn into the chair cover (see Sensor Locations picture) and the distance sensormounted above the chair. The electronics were mounted to the back of the chair as seenbelow.

The attached video shows Posture Care in action and demonstrates that our methodworks. We intend to save companies money and improve the health of office employees.
