Virtual Reality can make your mind sharper
New York, June 15: Not just gaming or entertainment, virtual reality (VR) can also help people recall information better as opposed to desktop computers, say researchers including one of Indian-origin.
The team from University of Maryland conducted in-depth analyses on whether people learn better through virtual, immersive environments, as opposed to more traditional platforms like a computers or tablets.
They found that people remember information better if it is presented to them in a virtual environment.
"This data is exciting in that it suggests that immersive environments could offer new pathways for improved outcomes in education and high-proficiency training," said Amitabh Varshney, Professor of Computer Science, in a survey published in the journal Virtual Reality.
Varshney leads several major research efforts involving virtual and augmented reality (AR), including close collaboration with health care professionals interested in developing AR-based diagnostic tools for emergency medicine and VR training for surgical residents.
For the study, the team used the concept of a "memory palace," where people recall an object or item by placing it in an imaginary physical location like a building or town.
This method has been used since classical times, taking advantage of the human brain's ability to spatially organize thoughts and memories.
"Humans have always used visual-based methods to help them remember information, whether it's cave drawings, clay tablets, printed text and images, or video," said Eric Krokos, doctoral student in computer science and lead author on the paper.
"We wanted to see if virtual reality might be the next logical step in this progression," Krokos added.
For the study, the researchers recruited 40 volunteers unfamiliar with virtual reality and split the participants into two groups -- one viewed information first via a VR head-mounted display and then on a desktop and the other group did the opposite.
The results showed an 8.8 per cent improvement overall in recall accuracy using the VR headsets, a statistically significant number.
Many of the participants said the immersive "presence" while using VR allowed them to focus better.
"This leads to the possibility that an immersive virtual environment could enhance learning and recall by leveraging a person's overall sense of body position, movement and acceleration," said Catherine Plaisant, Senior Research Scientist in University of Maryland Institute for Advanced Computer Studies.

CPI(M) demands Centre's intervention to end violence in Manipur
New Delhi (PTI): The Communist Party of India (Marxist) on Monday expressed concern over the situation in Manipur and demanded that the Union government intervene to end the violence.
In a statement issued here, the Politburo of the CPI(M) also held Chief Minister Biren Singh responsible for the deteriorating situation.
“A grave situation has developed in Manipur with the intensification of violence due to killings and counter-killings on ethnic lines. 20 people have been killed in various incidents since November 7,” the CPI(M) said.
The party said that the discovery of five bodies of women and children, who were abducted earlier in a horrific incident, has inflamed the situation in the Valley.
The Left party questioned why Singh had been allowed to continue in his post.
“Right from the beginning, it was Chief Minister Biren Singh who was responsible for the deteriorating situation, yet the Central government and the BJP, as the ruling party, refused to remove him and allowed him to continue,” they said.
A situation has now arisen where the writ of the state government and the administration does not run, the Left party said, adding that it is time for the Central government to strongly intervene to immediately put an end to the violence.
“It must also begin serious efforts for a political settlement that restores peace and safeguards the rights of all ethnic communities in the state,” they added.
The situation in Manipur, which has been reeling from ethnic strife since May last year, has become even more volatile following protests and violence after the recovery of the bodies of women and children.
More than 220 people have been killed and thousands rendered homeless in ethnic violence between the Imphal Valley-based Meiteis and the adjoining hills-based Kuki-Zo groups since May last year.
