Yesterday a friend of mine posted 360 degree photo in fb wall, from there I came to know Facebook supports 360 degree photos which can be viewed on desktop, iOS, Android, and a virtual reality headset. This may be after effect of Facebook overtaking a company Oculus which has focus on Virtual Reality (VR) technology.
360 degree photos are typically taken with a 360-degree camera which are now available in different models of Camera of brands like LG, Samsung, Go Pro, Sony etc. For smartphone users this type of image can be generated by taking a panoramic photo.
The 360 degree photos can be viewed by clicking and dragging your mouse along the image to get a different view where as on mobile viewer can move the smart phone left, right or up, down to feel the 360 degree photo.
