Hi, we are planning to equip our social science research lab with devices that would enable us to use social sensing, i.e. to analyze nonverbal and paraverbal behavior of our research participants in different situations. We would like to record our participants and then use a software that can automatically extract body movements and speech patterns of interest so that we don't have to rely on coders to watch and observe the behavior on videos. So my first question is, do you know any programs that could do this?

In our lab, we would also like to use motion sensors to detect movements more precisely. Do you have any recommendations for where to get motion sensors that would be useful for scientific research? And, same as for videos, do you know any programs that could extract and help interpret these types of data?

Any help is much appreciated :)
