I've spent my weekend trying to make sense of all the data we recorded at the experiment. I've been building graphs (well trying to remember how to build graphs), some of which make no sense but look nice and others that just make me want to do more complicated things!
We were open for 8hrs over two afternoons and we received over 20 hours of attention! and 3213 attention hits.
The average duration of an Attention givers visit was 13.5mins.
Giving an average 36 attention hits.
This is a graph of Simon's attention hits, showing the screen, the time intervals of hits and hit counts (this is one of the groovy yet uninformative graphs!).
