In terms of devices,  it is not easy to understand what will be the next standard in archaeology.
So far the focus of this research field was mostly based on the data capturing and post processing, but very few affords were made to explore the possibility to use these new kinds of data in different scenarios (not just in Lab).

 Today new technology  allows to generate very precise 3D models of any archaeological context, perfect  replicas of how the layer looked like the exact moment before its destruction. If stored properly, these information, can provide a sort of  time travel application to keep track of all the actions (physical and mental) that defined the research process during the entire investigation time frame.
 The use of these new devices (easy to carry everywhere, quite robust and with no keyboard)  allows a direct access to our ongoing work directly into the excavation, bringing more and more the labs activities into the archaeological context.  This represents an important step in terms of "information & cognition", because allows to hypothesize scenarios where  field activities and  post processing work are merge together in the same context.
 Recently the National Research Council of Italy, ISTI (Institute of information Science of Pisa) ,  realized a prototype to visualize complex 3D models through IPad, this application is called MeshPad, and it is basically an IPad version of MeshLab. These new tools for Pads (IPad, Galaxy), also if incomplete and not designed primarily for archaeological research (as usual...),  represent an incredible opportunity for new experiments based on data management, and opens to new interesting research questions about how our perception of the data affect (increase or decrease)  our capacity to interpret.

After Catal

During the summer I have bee in Catal Huyuk excavating for a couple of weeks and doing some new test, in this occasion I combined computer vision techniques (photoscan) and Total Station. The experiment was very successful because for the first time in my "field experience" I had the chance to generate a scaled and High Resolute 3D model of the excavation every day !!! every evening I had the full documentation ready in HQ and (more important) a 3D model to brainstorm the situation etc. It was very exiting, but more important this experiment open to new questions about archaeological methods and excavation strategy... I think this technique is going to have an important role in the future excavations, but the only technique is absolutely not enough, now we need to figure it out how to use this new kind of data in a large scale and more important what are the possibilities for a better comprehension of the stratigrapy. Before Catal I did some experiment in Uppakra, together with Matteo Dellepiane (ISTI) and Marco Callieri (ISTI) we will present these preliminary results to the International Symposium on Virtual Reality, Archaeology and Cultural Heritage, VAST 2011, soon the article will be available on my profile : Documentation and Interpretation of an Archeological Excavation: an experience with Dense Stereo Reconstruction tools
