The Circus Maximus Experience, opened in Rome this week and offers visitors the chance to relive the ancient splendors of chariot racing in the Imperial period of Rome through augmented and virtual reality. The innovative project implements interactive display technologies never before used in such a large outdoor area.
“Now you find yourself in front of the Arch of Titus, which was possibly built in the place of a more ancient arch and dedicated in the year 81 After Christ by the Roman Senate and people to Emperor Flavius”.
This is just an example of what modern-day visitors will be listening to in their headsets, while at the same time through special visors see a virtual rendering of the majestic 20-meter Arch of Titus in Rome’s Circus Maximus.
Thanks to a ground-breaking project using interactive display technology never before used in such an extended outdoor area, visitors are able to re-live the life in one of Rome’s undisputed landmarks.
Visitors immerse themselves in history for with overlapping images from the past and those of the reality of today. They are able to visualize architectural and landscape reconstructions of what life was like during all of the historical stages of the Circus Maximus.
They can see the ancient Murcia Valley enriched with buildings and walk around in the Circus among the shops of the time. They can visualize the Circus during Imperial times, the Middle Ages and in a more modern age.
The full itinerary involves eight stops including: the valley and the origins of the Circus, the Circus from Julius Caesar to Trajan, the Circus during the Imperial age, the cavea or tiered seating arena, the Arch of Titus, the tabernae or shops, the Circus during the Middle Ages and modern age, and lastly “A Day at the Circus” for an experience of the exciting chariot race of the quadrigas with the screams of incitement of the public and the overturning of wagons.
Virtual reality (VR) technology can identify early Alzheimer’s disease more accurately than ‘gold standard’ cognitive tests currently in use, says a study.
The findings, published in the journal Brain, highlight the potential of new technologies to help diagnose and monitor conditions such as Alzheimer’s disease.
“These results suggest a VR test of navigation may be better at identifying early Alzheimer’s disease than tests we use at present in clinic and in research studies,” said study lead author Dennis Chan, Professor at the University of Cambridge in Britain.
The researchers developed and trialled a VR navigation test in patients at risk of developing dementia.
For the study, the research team recruited 45 patients with mild cognitive impairment (MCI). Patients with MCI typically exhibit memory impairment.
They took samples of cerebrospinal fluid (CSF) to look for biomarkers of underlying Alzheimer’sdisease in their MCI patients, with 12 testing positive. The researchers also recruited 41 healthy controls for comparison.
All of the patients with MCI performed worse on the navigation task than the healthy controls. However, the study yielded two crucial additional observations.
First, MCI patients with positive CSF markers — indicating the presence of Alzheimer’s disease, thus placing them at risk of developing dementia — performed worse than those with negative CSF markers at low risk of future dementia.
Secondly, the VR navigation task was better at differentiating between these low and high risk patients with mild cognitive impairment than a battery of currently-used tests considered to be gold standard for the diagnosis of early Alzheimer’s, the study said.
The researchers are now working towards developing apps for detecting the disease and monitoring its progression.
“We live in a world where mobile devices are almost ubiquitous, and so app-based approaches have the potential to diagnose Alzheimer’s disease at minimal extra cost and at a scale way beyond that of brain scanning and other current diagnostic approaches,” Chan said. (IANS)
