All data are recorded in a more detailed protocol file. In this file we record the different parts of the signal and their signal strength and also information from sensors like movement and barometric sensors. At the moment this protocol file is for internal use only, but there could information extracted afterwards.
After, for instance, 30 minutes operation you generate the following data sets (this is the information you will finally provide to evAAL together with this questionnaire in a format that must be agreed before the competition). Please provide information about the files with data (examples are, text file, or video) and format (.csv, .txt, .xls…).
- An array that include: [time, device IDs, distance, alphaAngularValue, PhiAngularValue, X-Position, Y-Position, arcRadius], nearly every second.
Files:
- A file containing this samples in csv format.
