The Field of View for the HoloLens has been a point of discussion for consumers and press ever since its unveiling back at E3 in 2015. Once previews started hitting the Internet, folks suggested that the HoloLens offers of a rather narrow field of view. An official stat from Microsoft has further reinforced that notion.
Before we go any further, you might wonder what field of view (or FOV) means. Basically, in the genre of games and display, the FOV is how much of the world you can see on screen at any given time. A narrow field of view, then, implies that you won’t be able to see much of the virtual space at once.
Microsoft’s Bruce Harris, Technical Evangelist, spoke at an event in Tel Aviv. It was there that he revealed that the HoloLens will get up to 5.5 hours of life on a single charge, though heavy usage would drop that down to 2.5 hours. That’s pretty impressive battery life for totally wireless tech. Part of what makes that battery life so solid is the narrow FOV.
Harris indicated that the field of view for the HoloLens can be compared to looking at a 15-inch display from a distance of about two feet. Right, so, narrow.
As for how this will work out in actual use? I’m not so sure. I imagine users will be doing a lot of head turning in order to see all they want to see at once. I’m just hoping the FOV isn’t so narrow that it’s annoying. Only time will tell.
