But I wanted to have full control over analyzing the data, so I instead opted for a general-purpose application called Sensor Data from Wavefront Labs. As the name implies, the app can record ALL of the information available from the iPhone’s five different sensors — and then export it as an easy-to-read data file.
Here’s an example of one of the runs – I pressed the “start capture” button at the top of the lift, choosing the option to record a line of data every 1/2 second. At the end of the day, I exported the file from my iPhone to my PC, and opened it up in the SAP Visual Intelligence data discovery tool.
From there, I was able to quickly and easily create a series of graphs and charts showing different aspects of the run:
The fun part was synchronizing the analysis with video I took with a helmet-mounted GoPro camera – watch the video below to see more about the process, and what happened during the highlighted area in the chart!
