One of the most significant limitations of the HoloLens has always been its narrow field of view (FOV), which can make augmented reality experiences feel somewhat restricted. However, it seems that Microsoft may have found a promising solution to this issue. According to a recently filed patent submitted to the World Intellectual Property Organization in April, the company is exploring a new method to expand the FOV by splitting the image and projecting it through two separate components before recombining them.
The patent was developed by Microsoft optical engineers Tuomas Vallius and Jani Tervo. They explained that even if the central component only supports a 35-degree FOV, combining it with other elements could result in an overall field of view of at least 70 degrees. This approach could significantly enhance user immersion and make the HoloLens more practical for real-world applications.
According to the patent description, using intermediate components allows for a field of view greater than 70 degrees, potentially reaching up to 90 degrees or more. This is achieved by directing different parts of the visual field to separate components, which not only improves the user experience but also reduces power consumption. In fact, this method can save up to 50% of electrical energy compared to traditional systems that don’t split the field of view.
While patents don’t always translate directly into product features, this development is still exciting. It suggests that Microsoft is actively working on improving the HoloLens, and it’s possible that future iterations of the device could incorporate these innovations. If implemented, this technology could mark a major leap forward in mixed reality hardware, making the HoloLens more competitive and versatile for both consumers and enterprise users.
