VERA the use of Digital Devices Presented by: Prof Mark Baker ACET, University of Reading Tel: +44 118 378 8615 E-mail: Mark.Baker@computer.org Web: http://acet.rdg.ac.uk/~mab mark.baker@computer.org
Outline • Aims and objectives of the VERA project. • Using Digital Devices: • Digital Pens, • Digi Memopads, • Screen-based devices, • GPS. • Summary and Conclusions. mark.baker@computer.org
Using Digital Devices • The VERA project aims 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 is to create a situation where “the information flows seamlessly from excavation, through post-excavation to archive and publication”. • In addition, we are creating various tools and utilities that help the post-excavation research processes. mark.baker@computer.org
Silchester Roman Town The 'Town Life' Project mark.baker@computer.org
Silchester/VERA Web sites http://vera.rdg.ac.uk/ mark.baker@computer.org
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. mark.baker@computer.org
Integrated Archaeological Database (IADB) • The IADB is a key component within the Silchester and the VERA project. • The IADB was designed to address the data management requirements throughout the lifespan of archaeological excavation projects, from initial excavation recording, through post-excavation analysis and research to eventual dissemination and archiving. • THE IADB is used for recording: • Finds, Contexts, Sets, Groups, Phases, Objects, Images, Illustrations, Stratigraphy Diagrams, Documents and Bibliography References. • Based on MySQL, PHP, Javascript, AJAX and SVG. mark.baker@computer.org
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. mark.baker@computer.org
Contexts mark.baker@computer.org
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. mark.baker@computer.org
Thoughts on the Digital Pens Pros: • 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! mark.baker@computer.org
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.

Digimemo Pad mark.baker@computer.org
Digimemo Pad Specification mark.baker@computer.org
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! mark.baker@computer.org
Global Positioning System mark.baker@computer.org
Other Digital Devices • Digimemo pad: • Can cope with the current paper-based context sheets, • Easy to use for both text and diagrams, • Not robust, four used during 2008 excavation, three failed! • IPAC/Laptops/Nokia 800s • All work well and are useful on-site! • But can not see the screen in direct sunlight, need to be in shade or in hut to use these devices. • GPS • Provides XYZ coordinates for contexts and artefacts a lot faster… staff need training though! • Look at cheap laptops again this next season! mark.baker@computer.org
Summary • The use of various digital devices are speeding up the process of inserting excavation data into the database: • In the past, entering the contexts would take three/four months efforts after the dig, • Now all the contexts are entered during the dig. • 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. • Some sceptics, but the majority of people who work on the excavation are happy to use the devices. mark.baker@computer.org
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. mark.baker@computer.org
