LG has been working on a new virtual reality (VR) and augmented reality (AR) head-mounted display (HMD) for some time now. Thanks to a recently published patent it looks like the HMD will include a new eye-tracking technology.
Titled ‘Personal immersive display device and driving method of origin’ the patent details a HMD with a built-in camera, which is able to determine the position of the users pupil. Based on the information that camera picks up the processor can determine the user’s gaze and use this to optimize the image that the user is viewing, while reducing the resolution and brightness of those not being viewed.
The patent was submitted back in August, 2017 and became available on 1st March, 2018 after being published by the World Intellectual Property Office (WIPO). It goes on to talk about how the application could be used for AR content as well rather than solely VR. A prototype of the HMD was demoed back in 2017 and reports show that there were already cutouts for the camera pointing towards the unit offering a mixed reality (MR) user experience.
As reported on last year, the unit is said to have two OLED display with a minimum resolution of 1440 x 1280 pixels with a refresh rate of 90Hz. The patent also mentioned a 500 ppi (pixels per inch) which is sure to all work together to allow for a clear image. With the help of the eye tracking technology that LG are working on, the brightness of the display will adjust to match the users gaze.
The prototype of the LG HMD was shown off back in October, 2017 where VRFocus first got a taste of some of the details regarding the unit. It was during this time that a Trademark was submitted that points towards the HMD being called the LG UltraGear VR. Additional details pointed towards it being a high-end tethered PC VR device similar in operation to the HTC Vive or Oculus Rift.
The SID Display Week is set to start on 22nd May, 2018 and LG are expected to be attending the event and giving more details on the LG UltraGear VR HMD.
VRFocus will be sure to bring you all the latest on this story in the future so stay tuned for more.
