Accelerometer-based gait analysis using mobile phones

Background and Motivation: 

There are a lot of various sensors in modern smartphones, such as an ambient light sensor, a proximity sensor, Global Positioning System (GPS), a compass, a gyroscopic sensor, an accelerometer and others. In this work we study potentialities of accelerometers, specifically gait analysis methods. Some of them have already implemented and been used successfully, such as pedometer. Other potentialities, in which we interested, are human identification and health monitoring. A number of biometric methods of identification have been introduced over the years, such as eye scans (retina or iris), fingerprint recognition, hand or palm geometry, voice recognition, facial recognition, heartbeat biometrics and others. But most of them either require expensive and specialized hardwares or are inefficient as often inexpensive systems are prone to errors of the second kind (for instance, builtin laptops fingerprint readers). Therefore we've decided to study the ability to identify human using his gait. It is inexpensive because of using built-in MEMS-based accelerometers and also requires no specific actions from the user except just walking. There are many articles on the topic of accelerometer based gait authentication, such as [1, 2, 3]. Other our interest is health monitoring, which now also is very topical and important. The works in this area are [4, 5, 6].

Project Summary: 

Our current ideas how to use accelerometer are to determine pattern of movement and to identify human: 1. Patterns of movement Our purpose is to calculate the rate of movement, but now it's very difficult task, so we use patterns. Movement is divided into three patterns: human isn't walking, human is walking and human is running. To determine pattern of movement we use FFT (Fast Fourier Transform). Depending on pattern we can, for instance, switch phone's modes, such as sound volume. 2. Identification The main idea is that certain identifier, called the Gate Data (GD), is calculated for every walking person. Then the GD of this person is compared with database of other GD and the system makes a decision on further actions. The principal calculations of getting GD are performed in the frequency domain. Therefore, the algorithm is also based on FFT. The algorithm of getting GD is shown in the Figure1. Since FFT calculations are very complex for smartphone's processors we perform calculations on the server: smartphone transmit accelerometer's data to server via WiFi.However, we have some problems with this system that we want to eliminate during this project. This problems connected with both the inaccuracy of device (we work with Nokia N900) and some domestic reasons, for instance, other clothes and footwear can change the gait. The problems with device lie in the quantization of the accelerometer's data that can't be changed. Therefore we should update our algorithm for this case.

Project goals and future research directions: 
<p>Working on the project we keep in mind several scenarios of using our ideas: 1. A certain organization want to check paths of employees in it's territory. The organization has server, which stores gate data of every employee. When employee enters the territory his smartphone connects to server and transmits accelerometer's data. The server performs the calculations and defines this person as one of the employee so it's possible to check where he is going and compare his current path with his path's pattern. 2. Theft detection. The smartphone performs the calculations uninterruptedly and if it is stolen, it will block and, for example, send warning message with location coordinates to police. 3. Our future research direction can be health identification, because these systems also work with accelerometer's data and because it's very important and interesting area.</p>

This will be a nice application to use in the mobile phones. With the advanced features provide in the gait analysis, it will be a nice one to have in any Smartphone. I think this does not requires any additional components since it is based on the build in sensors.Paris Tours Now
