One of the biggest drawbacks of the Microsoft HoloLens is the device's limited field of view but that may change in future hardware revisions. MSPowerUser
reports a patent application from Microsoft describes a method to double the field of view of the HoloLens from 35 degrees to 70 degrees. This will bring the technology closer to the 100 degrees field of view that is offered by VR headsets like the Oculus Rift.
Microsoft writes that to enable the use of internal reflection in the waveguide they are forced to limit themselves to a range of exit angles of around 35 degrees, which dictates the subsequent field of view of the hologram as seen by the user.They have however developed a clever technique to get around this limitation, by splitting the image sent down the waveguide into two elements, which then has 2 separate exits, and while each will be limited to 35 degrees, the subsequent final image seen by the user can span up to 70 degrees.
The patent was
filed on April 6, 2017 and was made public on October 19, 2017.
