On July 11th we presented the GeoActivity at this years ESRI Education User Conference taking place in San Diego, CA. The talk was scheduled in the Research session on spatial thinking. After the presentation we prepared a demo on the Hilton Hotel terrace (to have GPS connection) for the interested audience. Most of the peolpe have not seen the XO before, only heard about the project. Some interesting contacts and collaboration opportunities came up. For example with the GLOBE Program by NASA.
