Mobile App

The Mobile App was developed using Evothings mobile app development tool. It uses TI's MCU's Bluetooth LE capabilities to connect to the companion phone app and provide data to the user in real time.

Data

Data Representation:

The Mobile phone app allows for progress tracking throughout the day showing the thoracic T10 and lumbar L3 vertebrae sensor data. The graphs were developed to be easily interpretable by the user, anything outside the green zone is deemed bad posture. Furthermore we have a pie chart that displays the percentage of bad and good posture time the user undergoes. Overall our companion phone app provides extensive data that is easily comprehensible straight to the users phone.

This graph demonstrates the effectiveness of our filter that reduces the noise from ~6 degrees deviation down to a deviation of ~.5 degrees. This filter allows the user to have accurate data they can trust in.
