The VERA Project
9th June 2009 [email protected]
Outline• Aims and objectives of the VERA project.• Digital Devices.• Tools and utilities.• Sustainability.• Summary and Conclusions.
Using Digital Devices• The VERA project aimed to produce a fully-
fledged virtual research environment for the archaeological community.
• VERA Aims:– The overall aim of the project is to assess, enhance
and introduce new tools and technologies that can aid the archaeological processes of recording, manipulating and analysing archaeological data.
– Our goal was to create a situation where “the information flows seamlessly from excavation, through post-excavation to archive and publication”.
– In addition, we created various tools and utilities that helped the post-excavation research processes.

Silchester – An Overview• The annual excavation allows us to:
– Study the use of IT in an archaeological context; – Investigate the tasks carried out within an
excavation; – Ascertain how and where technologies can be
used to facilitate information flow within a dig; – Inform the developers how to adapt the tools
used in the trench and for post dig analysis.
• To ensure that the software and tools are appropriate we are engaging all the on-site team and the researchers who undertake post excavation analysis in the usability studies.

Research: Recording Urban Change
Integrated Archaeological Database (IADB)
• SQL Database, based on MySQL, PHP, Javascript, AJAX and SVG.
• The IADB provides data repository throughout the lifespan of archaeological excavation projects.
• THE IADB is used for recording:– Finds, Contexts, Sets, Groups, Phases, Objects, Images,
Illustrations, Stratigraphy Diagrams, Documents and Bibliographical references.

Digital Device Trials• We have experimented with:
– Hand-held IPAQs – good for querying database,– Ruggedised tablet PCs – sunlight a major problem,– Nokia 800s – OK, but hard to use on-site.– Digimemo pads – useful, but not very robust.– Wireless Web Cams,– Digitial Pens.

• Patented,• A tiny camera in the digital pen,• Tiny dot patterns and grids on the paper,• Pen moves across the dot patterns and grids,• Marks, coordinates and relative time points,• Send the stored sequences to computer.

Thoughts on the Digital PensPros:• Pens and paper are relatively cheap,• Work in a range of weather conditions as ordinary
paper and pencils,• Reassuringly “low-tech”,• Integrate well into existing recording
methodology,• Field Code system is very flexible.
Cons:• Field Code system takes time to learn,• Requires sequential input!• Forms based system could be better,• Formatted Context Forms are expensive,• Limited trial size!

2008 Excavation Summary
• 591 out of 1352 or 44% of context cards recorded with the digital pens.
• Simple training.• Robust (weather, mud and
student proof).• Speeds up post-excavation
work (context cards must otherwise be transcribed).
• Encourages legible handwriting.
• Paper master copy created in the trench in case of computer related disasters.
They Feel Familiar and Natural• Feel as comfortable as you normally write with
a regular pen on paper.• Immediately get both a digital record and a
hardcopy duplicate of your handwritten notes even when you are on the move.
• Instantly and digitally record your notes, ideas, sketches, drawings and flowcharts, without scanning.
• Any ordinary paper or notepad can be applied.• Only problem was that the out of the four
bought, three failed!• However, lots of future possibilities though!

Arch3D is data visualisation service of the VERA environment, allows the integration and investigation of the multi-dimensional datasets obtained from an excavation.
Sustainability• Worked with IT Services during VERA project,
established procedures and processes to support IT and Internet/WiFi on site.
• We have also established a model for archaeological practice that will be documented, publicised and passed onto other archaeological communities: – We believe that this model of archaeological practice will
be embedded into the Silchester excavation for the foreseeable future.
– This practice includes pre-excavation training, on-site guidance and help, the availability of the Internet/WiFi on-site, the use of digital devices, and easier and faster interaction with the IADB.

Summary
• The digital devices are speeding up the process of inserting excavation data into the database.
• This means that analysis and research can be undertaken immediately on the IADB, and publication are produced more quickly.
• The use of these digital devices means that we have to train the staff and students before the excavation, but it having a significant effect.
• Tools and utilities have been useful and are helping the archaeological community.
• Project was “user driven” – user engagement was very important during the whole VERA project.
9th June 2009 [email protected]
Conclusions• User driven design and implementation of tools
and utilities for the project.• Availability of the Internet and WiFi across the
site is very useful.• Up front and on-site training, and extensive
documentation helps the archaeologists take up the digital technologies and various tools more easily.
• Digital pens and Digimemo pads are a success, even though the latter was not that robust.
• Still cannot find a screen-based digital device that can be used easily in direct sun light.
