I've heard of playing cattle music, but VR? Wonder if it'll put herding dogs out of business? Just program a VR dog to herd them at a specific time of day.
But my other ponderance is, can they differentiate between VR and a real life threat? I've not played VR, but have heard how immersive it can be. Since cattle have no concept of VR, how would they know if they were under real threat?
This story emanates from Russia. I'm suspecting it's one of their 'utter bollocks' stories. VR headsets are quite expensive, now multiply that up to herd size. They could only be used indoors when presumably they're there to be milked then sleep. No practical use when they're outside. Unless they're cows that don't go outside, but are there dairy farms where cows are inside all the time?
Nice video at the link, of the farmer playing trombone for his cows. They do seem to be fascinated by music. There's numerous other videos around of people playing various instruments with similar effect.
Owing to significant differences in their visual acuity, field of vision and relative deficiency in depth perception there's no way a VR headset designed for humans' wide-ranging binocular vision would "fit" a cow's quite different panoramic field of vision, wide-ranging monocular vision and very narrow field of binocular vision. Cows also have relatively poor visual acuity / focus across most of their visual field. See, for example:
