N-CRiPT Public Seminar: What Does Your Walking Reveal About You?

Jointly presented with SGInnovate

Speaker: Associate Professor Terence Sim

Date & Time: Friday 18 June, 3.00pm – 4.00pm

Devices such as smartphones and smart watches are commonly used for daily step count these days. But did you know that the way one walks (gait) reveals a lot more than one’s fitness? Gait reveals an individual’s identity as well as physical attributes such as height and age. As such, gait can be used to secure smart devices, provide personalized services, and perhaps even detect walking abnormalities. In this talk, we will explain our research into Inertial Motion Unit (IMU) gait which may be acquired from modern smart devices. We show how gait may be used for continuous authentication, and its privacy implications.

We posit that by using smart earphones (eg. Apple AirPods), we will soon be able to use gait for analyzing some sporting activities, and for detecting walking and running defects.
