Gait Data
What is GAIT: Gait is the a person walks. A person's gait can include stride length and acceleration in the x, y, and z direction.
How to interpret data: In order to interpret data you need to be able to organize and graph the data that has been received. From there you have to study patterns that seem common or constant for known factors that you could use to figure out the unknown factors on different factors.

Pattern noticed: If between the first and the second data point collected in the csv file raises then the person is 5’10 0r taller. If the data points drop then the person is 5’9” or below.
Reflection:After many hours of attempting to interpret data I found a pattern that will can help determine the height of a person based off of there GAIT but is not very accurate or precise. This is due to many factors. For example we used an iPhone tapped onto someone. That made our data that we collected super inaccurate because the phone can be bouncing around ruining the data. Secondly the fact that we used an accelerometer does not predict someone's height because everyone walks differently. For example someone can be 7 feet tall but might walk the same speed and acceleration as someone who is 4ft. This can be due to the fact that the shorter person is used to a faster walking pace of friends or it could be due to the fact that the 7ft person is tired and is walking slowly and the 4ft person could of just drank 7 cups of coffee. There was also no set distance to walk or amount of steps to take. You also can’t tell someone's height based off of leg length because there is no leg to torso ratio that everyone has. There was also the issue of learning how to use google sheets and excel spreadsheets. This was the first time I had used this software so it took about 10 hours to understand how to graph the data. In the end all the factors were put on us on purpose. Our teacher gave us this impossible challenge to see how we work to answer it.
