Data Collection

In this project, we collected in-bed posture pressure data from multiple adult participants using two different types of pressure sensing mats. To the best of our knowledge, our dataset, PmatData is the first publicly-available dataset of pressure sensor data which includes various sleeping postures. PmatData contains pressure data from two separate experiments. These two experiments are:

Data Files

The experiment-info.docx file provides information about subjects and postures, including visual diagrams. There are also subject-info-*.csv files in each experiment subdirectory describing subject information.

The data files are provided in tab delimited text format, listed in subdirectories named after the experiment number and subject number.

For experiment i, the text files are named after the position number from 1-17. Each file contains multiple frames of recordings, with the 2048 columns representing the 32x64 pressure sensor measurements, and each row giving a new set of samples.

For experiment ii, the text files are named after the 29 position numbers. Each file contains one average of multiple frames of recordings. In contrast with the experiment i text files, the 27 columns and 64 rows represent the 27x64 sensor matrix.
