Data Collection/Purchasing Components

Today the team split up into our software and hardware subteams and focused on separate tasks that would help us to attain our goals. Alex and Eric, who both work on the software aspect of the project, conducted human activity trials for data collection on the Samsung Simband. These trials were meant to understand the patterns and signals that downloaded from the Simband accelerometers, and understand the differences between each motion. The motions that were tested involved were walking at normal speed, slow walking, resting while sitting and resting while standing. Each of the three trials recorded one minute of each activity, which Eric and Alex performed individually. All the trials cumulatively provided us with 30 minutes of data to analyze and organize in Matlab.

For the next stage they will be to collecting the rest of the trials for the human activities like running, walking with an object like a cane, using a walker to simulate older individual. Also, using the standard devices to see how the step counters work on each device. From there, this additional data will be downloaded and stored in Matlab, so Eric and Alex will be able to begin the data analysis and pattern recognition for the data.

Meanwhile, Karly and Roy focused on the hardware aspects of the project; specifically on which components to purchase. We had already visited Microcenter and had purchased an Arduino Uno. Karly conducted research on how to produce a pedometer using the arduino. She created a list of components need to produce this device and will be ordering them later this week. Meanwhile, Roy Installed Arduino software on PC, researched connection of Bluetooth modules with the Arduino Uno.
