AR Arbor Low project begins

Arbor Low

Arbor Low is one of only two Neolithic enclosures in the Peak District. It is a nationally-protected archaeological site and one of the most visited archaeological monuments in the Peak District. The enclosure contains a stone circle with 50 white limestone slabs, all now fallen. The aim of this TUoS SURE project is to use Augmented Reality (AR) so that the stones can be viewed standing and interacted with in situ. The team working on this is Steve Maddock (Computer Science), Graham McElearney (APSE), Bob Johnston (Archaeology) and Eleftherios Ioannou (Computer Science), our TuOS SURE student.

Augmented reality experience brings Sheffield’s lost medieval castle to life

Sheffield’s medieval castle (@SheffieldCastle) is long gone, destroyed as a result of the English Civil War in the mid-seventeenth century. Our AHRC/EPSRC-funded project, in collaboration with @humanvr1, brought it back using Augmented Reality so that it could be displayed in situ in Sheffield, where it once stood. Our EuroVR 2018 research paper on the work can be viewed at White Rose research online. More details: TUoS news story, Immersive Experiences showcase event

We also built a further AR version for display during Sheffield's Festival of the Mind 2018 and a virtual reality version, available for download at: https://experiencecastlegate.group.shef.ac.uk.

The work was picked up by a range of media outlets: BBC News, BBC Look North (which shows people interacting with the exhibit at the Millennium Gallery), Sheffield city council news, Sheffield Star, Yorkshire Post, History Scotland, The Vintage News, Exposed Magazine, RMC media, Wikipedia. The model was also projected on a wall at Castlegate during Festival of the Mind.

The corpus we collected for our work on studying the Lombard effect in visual speech is available at http://spandh.dcs.shef.ac.uk/avlombard/. The picture shows the bespoke head-mounted camera system that was built for collecting the corpus. More details in A corpus of audio-visual Lombard speech with frontal and profile views, The Journal of the Acoustical Society of America.
