It’s been a while since Microsoft has provided an updated on its HoloLens mixed reality (MR) head-mounted display (HMD). The company revealed the device back in January 2015, but has remained quiet on it since. News on the device is expected at the company’s Build developer conference, which just kicked off, but a recent patent filed by the company is already providing hints into an intriguing potential new feature for the device.
As reported by PC World, Microsoft has patented a technology which allows augmented reality (AR) glasses to interpret people’s emotional reactions. The patent covers ‘see-through, head-mounted display and sensing devices’ that can ‘detect audible and visual behaviors of a subject in a field of view of the device.’ HoloLens falls under this category of device, providing a see-through lens that allows users to interact with holograms.
An image from the patent, seen above, sees a HMD registering the facial expressions of a person in its view and listing the emotion on the display. Another image, below, appears to be reading a human’s body language. HoloLens itself includes a depth camera that could scan objects, which could be used as part of this system. With the patent granted yesterday, it’s not likely that the company will touch upon this technology at Build.
VRFocus will continue to follow HoloLens closely, reporting back with the latest updates on it.
