This plot shows the raw data collected by Smart Shoe System during a simple exercise on the treadmill. Our training subject was walking at approximate speed of three miles an hour. We demonstrate the dynamic forces measured by the shoe accelerometer sensor (top plot) and the pressure changes at four significant points of the shoe sole (bottom plot).

One can observe how the dynamic sensor data is correlating with pressure data. When the pressure data shows near zero values the foot is lifted and traverses the step distance. It is also visible that the time of the foot on the ground is longer then in the air.

This plot shows the raw data collected by Smart Shoe System during a bit harder exercise on the treadmill. Our training subject was running at approximate speed of nine miles an hour. We demonstrate the dynamic forces measured by the shoe accelerometer sensor (top plot) and the pressure changes at four significant points of the shoe sole (bottom plot).

One can see again how the dynamic sensor data is correlating with pressure data. When the pressure data shows near zero values the foot is lifted and traverses the step distance. It is also visible that the time of the foot on the ground is much shorter then in the air. When this plot is compared with Fast Walking one can see that the step interval is shorter. Not by much however. Obviously during running exercise we are traversing much longer distance in a bit shorter time and our feet are mostly without contact with the track.

For a comparison purpose here is the plot showing the raw data collected by Smart Shoe System during a very slow walk exercise on the treadmill. Our training subject was walking at approximate speed of two miles an hour. We demonstrate the dynamic forces measured by the shoe accelerometer sensor (top plot) and the pressure changes at four significant points of the shoe sole (bottom plot).

This plot is very similar to the one showing "Fast walk". There are however some interesting nuances telling a lot about gait and balance.

Here are plots of raw data collected by Smart Shoe System during a brief jumping (upper graph) and bouncing (lower graph) exercise. The differences are clearly visible. Most notable, the bouncing graph shows high uniformity and no presence of force at the "heel" (dark red) sensor.

Additionally is obvious that the bouncing interval is much shorter then jumping by 2X factor. With our system we can very well illustrate the athlete action, for example during the basketball dunk jump, and compare different styles and different players.
