Explanation of Overall Project Design

The system block diagram above is the plan for the system we will be developing the semester for our final product. As it can be seen, the system is divided into the hardware and software side. Alex is the software lead while Karly is the hardware lead. From the hardware side, we have the Samsung Simband which is connected to the wrist and the hip connecting device. We have decided to include the hip connecting device because some users may have limited wrist mobility due to their walking style or using a cane/walker. The device on the hip is necessary because it provides alternate data from a different point on the body. This will allow us to create a more accurate algorithm to determine whether or not steps are being taken because we will have more data from more points to analyze.

The software side of the project consists of the SAMI website which is a cloud that collects time-stamped accelerometer data from both the Simband and the hip connector device. The data is then downloaded into our MatLab application where it is processed and analyzed. A step count is then produce and the display in the GUI updates the step count. The MatLab application acts as a preliminary model for the algorithm and GUI application that would then be translated onto the Samsung Simband in future developments of this device past this semester.
