The measure system in action

At first, a detailed determination of the current health status of the affected person takes place.
This includes the perceived afflictions, the foot form, shoe size and health history.
Only then, the decision about a measurement can be made.

While walking, no two steps are ever alike, which is why a measurement of only a few steps makes no sense. The gained data can be statistically faulty and is thereby not representative of the real facts. On the other hand, when collecting massive amounts of data, all results spread around a midpoint. This midpoint shifts in direct correlation to the tread angle of the foot and possible dysfunctions.
Because of this, a measurement time of 12 hours is recommended to display a whole day. To inspect the effects and effectiveness of made provisions, future measurements are endorsed.

New approach - intelligent gait analysis

The InGAsys measures the tread-angle of the foot to its running surface, the direction of gait deviation, the stride frequency as well as the tread momentum.

While walking barefooted and complete soil contact, the tread angle is zero. Through shoes and inlays, this angle is often changed and the pressure, as well as the force distribution in the body differs from the naturally ideal allocation.

At this point, the indispensable foundation of the InGAsys, “the theory of event-chains” applies. The feet are the basement of humans. Any alteration on the feet continues its impact through the body up to the head, which can cause health problems in several areas such as the knees, hips, the back and shoulders, as well as the head.

Hardware description

The sensor unit hardware is equipped with a micro-USB plug and Bluetooth Low Energy (BLE) for data transmission. The long term measurement capabilities of up to 28 hours are enabled by a powerful CPU, 2GB NAND-data storage and a button cell battery. Due to the integrated software module, measurements can begin and end independently, which allows for recordings over the weekend. [Die Handy-App gibt es doch noch gar nicht… würde ich weg lassen, denn sonst liest das ein Entwickler und fragt, warum die denn dann noch entwickelt warden soll?]

The accelerometer, measuring the alignment of the contact surface of the subject to the ground, operates at 100, 200, 400 and 800 hertz, ensuring solid data evaluation under all circumstances.

While measurements for high-performance athletes demand a frequency between 400 and 800, 200 hertz are sufficient for the collection of all relevant data in everyday life.

For demonstration purposes the system also offers a live transmission of measurements at 100 hertz via BLE.
