Overview

This page contains information about the on-going projects in human activity recognition at the University of Washington.

Platforms

The current platform that we're using consists of an embedded processor component, called an iMote2, and a sensing component called the MSB2 (Multi-modal Sensor Board). The combination of the iMote2, MSB2, and the system software is often referred to as the MSP (Mobile Sensing Platform).

In addition to the MSP we've also been using a number of cell phone platforms to provide wide area communications, display, local interaction capabilities, and additional sensors.

Component Details

More information about the various platform components can be found here:
• iMote2 - The Linux embedded computational platform that forms the heart of our wearable sensing platform
  • More information about the iMote2 and the Linux software can be found at the PlatformX wiki
  • Compiling the iMote2 kernel
• Sensor Boards - A brief description of the sensor boards that are being used

Phone Platforms

In addition to the embedded platforms we are also using serveral types of smart phones.

Nokia Phones

• Nokia N80
• Nokia E70
• Nokia Phone Codes - These codes can used to retrieve useful information about your phone such as serial numbers, and MAC addresses.

Software Tools

Logging Software

• msb server - the program used to record data from the sensor board

Useful Unix Commands

• Mounting a jffs2 image

UWAR Files

UWAR files (University of Washington - Activity Recognition) are a simple binary format used to store data.
• overview - a brief description of the uwar format
• uwar tools - contains a description of the various tools created to work with uwar files

Matlab

• Plotting wide images - Program to plot images with an extremely wide aspect ratio (i.e. hours of data plot vs. a small y-axis with good time resolution)
• Compositing Images - Matlab function to composite images (like those generated by plotting wide images.

Legacy Support

• Journal Viewer - The windows Journal Viewer used for some annotation tasks.
