OverviewMonitor a patient outside of a hospital settingA tool for healthcare professionals to diagnose and
monitor a patient’s problems and progress over the long term
Assess daily activities such as lifting their foot, measuring distance traveled, room monitoring, etc. will be upgraded later by adding complex and costly sensors
Achieve objectives with three different groups: data acquisition, footwear and a walker
Operate on a $1000 budget shared between three groups

To measure forces in different areas of the foot
In depth analysis when combined with walker provides early diagnosis of hip and leg problems
Monitors progress in rehabilitation
Portable design makes analysis more convenient

BackgroundData acquisition systems are processes used to collect and
interpret information.The data acquisition process is integral to all design projects. Our job as Data Acquisition group is to interpret and present
the data collected by the motions sensors on the footwear and the walker in the form of graphs and tables that others can read and use.

IssuesWe are finding that it is
possible issues may arise when it comes to data transmission.
The Walker and Footwear groups have not decided how they want to transmit data from their sensors, so we will continue to communicate with and assist them with their choices.

LabViewOur group’s main tool is LabView.It is versatile and flexible enough to accomplish tasks
in many different engineering fields.Using this software we are able to take raw input
signals and translate them into graphs and other readable data.

Our Expectation By the end of the semester:
Each part of the system should work correctly We should be able to collect and analyze data We should have a working prototype.
