London, Oct 31’2017: Scientists have shown that virtual reality (VR) can help reduce phantom body pain in paraplegics and and create the illusion that they can feel their paralysed legs being touched again.
“We managed to provoke an illusion: the illusion that the subject’s legs were being lightly tapped, when in fact the subject was actually being tapped on the back, above the spinal cord lesion,” said lead author of the study Olaf Blanke from Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland.
“When we did this, the subjects also reported that their pain had diminished,” Blanke added.
The results published in the journal Neurology could one day translate into therapies to reduce chronic pain in paraplegics.
Paraplegia is often accompanied by neuropathic pain due to the spinal cord lesion.
The patient feels pain originating from the legs, even though nothing else can be felt below the lesion.
The sensation of pain is real and yet completely resistant to drug therapy.
The new research shows that virtual reality may be the key to providing relief for this type of pain, and the solution comes from restoring a sense of touch.
“We tapped the back of the subject near the shoulders and the subject experienced the illusion that the tapping originated from the paralysed legs,” said Polona Pozeg, co-author of the study and now a neuroscientist at Lausanne University Hospital (CHUV) in Switzerland.
“This is because the subject also received visual stimuli of dummy legs being tapped, viewed through the virtual reality headset, so the subject saw them immersively as his or her own legs,” Pozeg added.(IANS)
New York, October 22, 2017 : Parents of small children have long been hearing about the perils of “screen time.” And with more screens, and new technologies such as Amazon’s Echo speaker, the message is getting louder.
And while plenty of parents are feeling guilty about it, some experts say it might be time to relax a little.
Go ahead and hand your kid a gadget now and then to cook dinner or get some work done. Not all kids can entertain themselves quietly, especially when they are young. Try that, and see how long it takes your toddler to start fishing a banana peel out of the overflowing trash can.
“I know I should limit my kid’s screen time a lot, but there is reality,” said Dorothy Jean Chang, who works for a tech company in New York and has a 2-year-old son. When she needs to work or finds her son awake too early, “it’s the best, easiest way to keep him occupied and quiet.”
Screen time, she says, “definitely happens more often than I like to admit.”
She’s not alone. Common Sense Media, a nonprofit group focused on kids’ use of media and technology, said in a report Thursday that kids ages 8 and younger average about 2 hours and 19 minutes with screens every day at home. That’s about the same as in 2011, though it’s up from an hour and a half in 2013, the last time the survey was conducted, when smartphones were not yet ubiquitous but TV watching was on the decline.
While the overall numbers have held steady in recent years, kids are shifting to mobile devices and other new technologies, just as their parents are. The survey found that kids spend an average of 48 minutes a day on mobile devices, up from 15 minutes in 2013. Kids are also getting exposed to voice-activated assistants, virtual reality and internet-connected toys, for which few guidelines exist because they are so new.
Some parents and experts worry that screens are taking time away from exercise and learning. But studies are inconclusive.
The economist Emily Oster said studies have found that kids who watch a lot of TV tend to be poorer, belong to minority groups and have parents with less education, all factors that contribute to higher levels of obesity and lower test scores. For that reason, it’s “difficult to draw strong conclusions about the effects of television from this research,” Oster wrote in 2015.
In fact, the Common Sense survey found that kids whose parents have higher incomes and education spend “substantially less time” with screens than other children. The gap was larger in 2017 than in previous years.
For more than a quarter century, the American Academy of Pediatrics held that kids under 2 should not be exposed to screens at all, and older kids should have strict limits. The rules have relaxed, such that video calls with grandma are OK, though “entertainment” television still isn’t. Even so, guidelines still feel out of touch for many parents who use screens of various sizes to preserve their sanity and get things done.
Jen Bjorem, a pediatric speech pathologist in Leawood, Kansas, said that while it’s “quite unrealistic” for many families to totally do away with screen time, balance is key.
“Screen time can be a relief for many parents during times of high stress or just needing a break,” she said.
Bjorem recommends using “visual schedules” that toddlers can understand to set limits. Instead of words, these schedules have images — dinner, bed time, reading or TV time, for example.
Another idea for toddlers? “Sensory bins,” or plastic tubs filled with beads, dry pasta and other stuff kids can play around with and, ideally, be just as absorbed as in mobile app or an episode of “Elmo.”
Of course, some kids will play with these carefully crafted, Pinterest-worthy bins for only a few minutes. Then they might start throwing beans and pasta all over your living room. So you clean up, put away the bins and turn on the TV.
In an interview, Oster said that while screen time “is probably not as good for your kid as high-quality engagement” with parents, such engagement is probably not something we can give our kids all the time anyway.
“Sometimes you just need them to watch a little bit of TV because you have to do something, or you need (it) to be a better parent,” Oster said. (VOA)
New Delhi April 14, 2017: The Federation of Indian Animal Protection Organisations (FIAPO) on Friday launched a campaign against reported cruelty in dairies by showing some shocking pictures through virtual reality.
The NGO, which promotes veganism, offers experience of virtual reality to consumers with an aim to sensitise people and consumers towards the unseen cruelty to dairy cattle.
“The #DontGetMilked Campaign strives to educate people about the cruelty towards animals in the dairy industry. It aims to help people make informed choices about the food that they eat and the benefits of a compassionate and plant-based diet,” Swati Poddar from FIAPO told IANS.

Asked if they are against the dairy or animal raising, FIAPO worker said: “It’s fine till no cruelty is involved.”
The campaign is bring to people the lesser known facts about the dairy industry where animals are often subjected to cruelty through untreated wounds, no vaccinations, artificial insemination and “Khalbaccha” (a makeshift calf).
Khalbaccha is a technique where a buffalo calf is killed and its head is stuffed with the straw to create a dummy. The dummy is hanged around the buffaloes who by getting smell of their child produce milk.
“Cows are considered sacred so they are not killed but the cruelty continues for buffaloes… Dairy animals are often subjected to cruelty,” Poddar added.
After Delhi, the FIAPO will hold the virtual reality sessions at Pune, Mumbai, Hyderabad, Chennai, Lucknow and Bengaluru. (IANS)

He was part of a session on VR at the ongoing Jio MAMI 18th Mumbai Film Festival with Star here, where the current usage of virtual reality was discussed, and how it will possibly shape the future.
Gandhi, who was also one of the panellists, said: “I am very excited about it (his film getting picked for UNVR). We (his team) are also doing a VR piece that we are shooting with actor Irrfan Khan. It is fiction. We will start shooting soon.”
Director Shakun Batra, the founder and curator of VR at the film festival, which will conclude on October 27, said: “It is the first VR film from India to get acquired and I think that starts a whole new phase where VR is something that has return on investments. People are interested in acquiring our films in VR, that’s a big move.”
He believes that VR will be a new platform for storytellers and filmmakers. (IANS)
