Eye tracking could be in the cards for HoloLens 2

We already know of some confirmed and rumored upgrades due to debut with the next iteration of the Microsoft HoloLens, including a defended Holographic Processing Unit and, potentially, a move to an ARM processor, simply a newly published patent could be our window into a much more impactful addition: centre tracking. The patent, filed by Microsoft in 2022 and published today, describes an eye tracking setups that seeks to solve the downsides presented by typical eye tracking systems while giving users a mode to interact with augmented reality (AR) content.

Integrated eye tracking would give a HoloLens 2, or whatsoever other head-mounted display (HMD), a whole new input method for interacting with content on the brandish. The HMD could rails a user's gaze to suit the mode content is displayed, while also assuasive users to input commands using just their eyes.

The only downside? Typical eye tracking systems can add weight, swallow up processing power, and interfere with a user's field of view. All three of these problems are what Microsoft gear up out to solve with its patented organization. From the patent summary:

To accost the issues discussed above, an center-tracking system is provided that includes a lite source configured to emit at to the lowest degree infrared (IR) light and a micro-electromechanical organization (MEMS) scanning mirror configured to directly the IR light. The system may further include a relay including at least ane prism, and the relay is configured to receive the IR light directed past the MEMS scanning mirror and redirect the IR light. The system may further include at least one sensor configured to receive the IR low-cal after existence reflected by the eye.

The current HoloLens headset leans on a combination of hand gestures to support user interaction. Adopting an eye tracking system would permit Microsoft to either driblet manus gestures completely or use them in combination with gaze interactions. Further, it could brand HoloLens and other HMDs more attainable for those with disabilities who may have a hard time using the current gesture controls.

Eye tracking isn't completely new to Microsoft. The company added native support for eye-tracking devices, similar those from Tobii, in Windows ten last year equally an accessibility upgrade, allowing people with disabilities to control their desktop without using a keyboard or mouse.

As with all patents, it'due south worth noting that this tech may never brand its way into a shipping production in this grade at all. Microsoft patents things all of the time that either never leave the lab or finish up acting as a base for further iterations. Still, we're days abroad now from Microsoft'southward MWC 2022 upshot, where information technology's expected to launch the HoloLens two,, and then nosotros'll know for certain what Microsoft may exist planning earlier too long.
