A new dataset has been added to CRAWDAD. <http://crawdad.org/copelabs/usense/> Data concerning social interaction and propinquity based on wireless and bluetooth. Contributed by S. Firdose, L. Lopes, W. Moreira, R. Sofia, P. Mendes. This data set comprises experiments carried out considering four Android devices, each named Usense 2, 3, 4, and 5, respectively. These devices were carried by people sharing the same affiliation during their daily routines (commuting between home and office, going to leisure activities, attending meetings in the office). All the data was collected each and every one minute. If you use these data, please let us know, and you can use the DOI 10.15783/C7M01M10.15783/C7M01M to cite.
