Sorry for the plug, but we're working on a project ("Suma") at NCSU 
Libraries that is basically a set of tools for collecting, storing, and 
analyzing data about the usage of physical spaces. The current client is 
web-based and designed for tablet use. We're using it for library 
headcounts now, and we're about to launch a trial as a possible 
replacement for paper-based reference transaction logs.

We are still pretty early in the development timeline, but we're going 
to release some code in the next month or so and will be attempting some 
active external testing later in the fall. It is an open-source project, 
but a reasonably full set of features may not be ready until early 2012. 
Right now, we're collecting and storing data quite reliably, but not 
retrieving or analyzing it.
