Overview
This page contains information about the on-going projects in human activity recognition at the University of Washington.
Mobile Sensing Platform
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).
- 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
- Current system images
- iMote2 How To's
- GPRS - Information on using a cell phone's GPRS connection on the iMote2 over Bluetooth.
- iMote2 GPIO pins/Alternate functions
- Connecting to the iMote2
- Sensor Boards - A brief description of the sensor boards that are being used
- MSB2/LSB Firmware - Current firmware images and protocol information
- MSP Boot Process - A brief description of the MSP boot process
- MSP System Software - Everything below, all on one page.
- msb-server - MSB hardware interface application
- msb-test - MSB testing application
- lsb-server - LSB hardware interface application
- lsb-test - LSB testing application
- cam-server - OV9650 camera image acquisition application
- gps-server - GPS hardware interface application, for use when a GPS unit is directly attached to an iMote2 serial port
- gps-debug - GPS status and debugging application
- cam-net-stream - Streams camera images over TCP/IP
- audio-stream - Streams audio samples over TCP/IP
- logger - MSB/LSB/GPS/Camera-to-UWAR logger
- central - IPC dispatcher
- proccontrol - Process monitor
- sb-update - Utility to reflash sensor board firmware
- buttonwatchdog - Utility that handles the power-off command from the power button
- Cross-compiling to the iMote2
- Compiling the MSP source code -- Required to build applications that depend on the sensor servers or other components
- Reading sensor values and controlling the MSP using IPC
- Using shared memory streams
Getting Started

Wiki Help
Please see documentation on customizing the interface and the User's Guide for usage and configuration help...
Wikipedia has some helpful information on how to edit wiki pages:
- MediaWiki FAQ
- Cheat Sheet PDF version
- How to edit a page
- Syle Manual
- Tutorial on using Pictures in a Wiki
- How to use lists in the Wiki
- How to use tables in the Wiki
- Notes on using tables
Wiki Add-Ons Used
- GeSHi has been installed along with an extension for MediaWiki. This enables code to be highlighted in several different languages.
- wikitable wikitables style was added to the common.css style
- Modified Image Gallery modification to mediawiki to support a column argument to image gallerys
