Tom's Guide Hololens 2 Rumor Roundup

on January 25, 2019

Tom's Guide is a popular blog dealing with technology and consumer electronics.

Here's their "Hololens 2 Rumor Roundup". As the reveal gets closer I would expect the tech press to include more references and analysis of the slew of MEMS scanning-specific patents and applications that may describe design elements for the new Hololens.

A new design?

Much of what we think we know about the new HoloLens design centers on a patent Microsoft filed and MSPowerUser obtained in January.

That patent, called "Compact Optical System With MEMS Scanners for Image Generation and Object Tracking," describes a new method for creating holograms using a single light source. The lighting system would also be used to sense depth and recognize gestures.

Since the first-generation HoloLens used multiple components to create the same functionality, it needed more space. The HoloLens 2 would likely be smaller and less bulky. In fact, Microsoft said that the technology would pave the way for "producing compact and lightweight NED devices." NED stands for Near-Eye-Display, a class of products the HoloLens would fall into.

Wider field of view

Microsoft’s first-generation HoloLens was hit hard by criticism that its native field-of-view of just 35 degrees wasn’t adequate. It’s been one of the biggest complaints about the device to date.

However, a Twitter user going by the handle WalkingCat in 2018 discovered a patent Microsoft filed called “MEMS Laser Scanner Having Enlarged FOV.” The patent describes a method for offering a device like the HoloLens, but expanding its field of view from 35 degrees to 70 degrees. Interestingly, the patent was filed in 2016 and says that the actual embodiment of the technology might have an even wider field of view.

In other words, Microsoft is at least hearing what people are saying and dreaming up ways to get a wider field of view in the HoloLens. Whether it’ll be able to pull it off in HoloLens 2 is unknown.
