Wockets: Open Source Accelerometers for Phones Sensors and Software for Real-Time Activity Recognition on Mobile Phones The goal of this open source project is to create software and hardware that permits automatic, 24/7 physical activity and context detection on common mobile phones. We are doing this by iteratively designing and testing Wockets -- miniature, low-cost hardware devices that will measure human motion using accelerometers. Wockets will send data to mobile phones that are processed by software running on the phone to automatically detect type, duration and intensity of physical activity. The software that uses Wockets will be free and open source. This project is a collaboration between the Northeastern University Personal Health Informatics program, MIT House_n, and the Stanford Prevention Research Center.

Site Surveys are conducted between the Gateway and each Node to analyze the radio signal strength and data transfer reliability between the two devices. DX70 devices report Site Survey results using the LEDs, with the flash rate indicating the radio signal strength. DX80 and DX9x Gateways report Site Survey results using the alphanumeric LCD display. Site Survey results are listed as a percentage of data packets received and indicate the signal strength of the received signal. Judging if the reliability of a network’s signal meets the needs of the application is not simply a matter of green, yellow, and red packets received. A good guideline is to keep the missed packets average to less than 40%. Mounting the network’s antennas higher, Using higher gain antennas, or Adding data radios to the network.
