HelpMate's UI interface includes, webcam stream with all the sensor value on a QVGA, on the shed of helmate. It's features include a whatsapp ping on exceeding speed or a message when someone need help or any sort of emergency message.
For sensor part, Basic Heterogeneous Application Interface (BHAI) is being used which is a cape for Beaglebone black with addition features. It is designed in our lab CEDT NSIT (
It's sensor database is managed by mysql and overlaying of sensor values on video is done by opencv image processing. For low demand of bandwidth a jpg stream is acheived with the help of ajax in jquery. Also for graphical representation of sensor value in real-time D3.js library is being used here.

History, video and other technical difficulties while pursuing this project is discussed at my blog
