US20240305330 - LINE-OF-SIGHT (LoS) COMMUNICATION CAPABILITY FOR A NEAR-EYE DISPLAY DEVICE

• 
  to establish discrete and low power consuming “walkie talkie” style communications when the users are within range and within an angle-of-arrival (AoA) of each other. For example, the angle-of-arrival (AoA) may be in a range from about 10 degrees to about 30 degrees (or more) letting the users communicate when they face each other. A line-of-sight (LOS) application executed on the near-eye display devices may be arranged to alert the users when line-of-sight (LoS) communication can be established. Thus, instead of going through a number of steps and establishing communication through an online communication application (and communicating over one or more networks such as the Internet), which may be cumbersome and power consuming, a user may simply accept or trigger the line-of-sight (LoS) communication when the other user is in range and within the angle-of-arrival (AoA).
• The line-of-sight (LoS) communication session(s) may be facilitated by (typically short-range) personal area communication systems such as ultra-wide band (UWB) communication, Bluetooth Low Energy (BLE) communication or similar ones.
• Thus, power consumption of the near-eye display device may be substantially reduced. Furthermore, two users in a crowded environment (e.g., a conference center) may communicate discretely. The communication modes (i.e., audio, audio/video) may be selected by the user(s).
• Moreover, a near-eye display device may be equipped with multiple wireless communication systems and a suitable one may be selected (and switched to) based on available power, a noise environment, a communication mode, or similar factors.
• As mentioned herein, a line-of-sight (LOS) application may detect another user within range and angle-of-arrival (AoA) and present an OPTION to initiate a communication session to the user (e.g., an icon, text, or other visual cue, and/or an audio alert). The user may make their selection (starting the communication session, ending the communication session, switching communication modes, etc.) through any input such as touch (a sensor on the near-eye display device), gesture, body movement, audio command, eye movement, etc.).

Welcome to our latest video, where we present an exciting new development in the field of research technology: the seamless synchronization between Cortivision's fNIRS and Tobii's eye tracker. This integration opens up new possibilities for researchers by combining functional near-infrared spectroscopy (fNIRS) with precise eye-tracking data.

In this video, we will showcase how this powerful combination can be utilized to gain deeper insights into cognitive processes and visual attention. We will demonstrate the setup process, provide examples of potential research applications, and highlight the benefits of using these synchronized technologies in your studies.

Whether you are involved in neuroscience, psychology, or human-computer interaction research, this cutting-edge integration offers unparalleled data richness and accuracy. Join us to explore how Cortivision and Tobii are advancing research capabilities and driving innovation.

Changes in facial thermal patterns can be used to determine mental workload, according to a new study from Nottingham University.

"Optical lens based on a Polarization Volume Hologram (PVH) layer having a freeform design and an optical system using such a freeform PVH lens. Depending on applications, the PVH layer can be transmissive, reflective, or partial-transmissive-partial-reflective. The freeform PVH layer consistent with the disclosure can be responsive to light with a certain wavelength, such as infrared (IR) light for eye tracking purposes in a head-mounted display (HMD).

[…]

A PVH layer can include a birefringent material layer including a plurality of birefringent molecules, and is also referred to as, e.g., “polarization sensitive gratings,” “polarization sensitive optical elements,” “liquid crystal gratings,” or “chiral liquid crystal elements.” For example, the PVH layer can include a liquid crystal (LC) layer including a plurality of liquid crystal (LC) molecules. The LC molecules are spatially orientated to enable at least one optical function of the PVH layer.

[…] The optical function of a PVH layer can be determined based on the configuration or manipulation of optical axes of the LC molecules in the PVH layer.

[…]

When the LC layer is thick enough, Bragg diffraction can be established.

[…]

The slanted Bragg grating can allow the PVH layer 100 to redirect incident light to be converged or diverged in reflection or in transmission. Thus, through further manipulation of the orientation of the LC molecules in the x-y plane, the PVH layer 100 can be configured to function as a lens, such as a reflective lens or a transmissive lens, that can, e.g., converge or diverge an incident light beam.

[…]

The PVH layer is also referred to as a “PVH lens.”: […]  wherein the first region and the second region have different optical powers, […], wherein an optical axis of the first region and an optical axis of the second region point toward different directions, […] wherein the first region and the second region are arranged side by side, […] wherein the second region encircles the first region.

MICROSOFT EP4405736 - 31.07.2024

Just as Magic Leap has being working on since long time, Microsoft now addresses the multi-focal plane with an intersting system architecture based on birefrangence and reflection.
Difficult to guess when we will see it implemented. For example Magic Leap patented up to 6 planes, with varied and ambitious architectures, but manufactured two, by now.
IP runs faster than technology and the realm is very slippery.

But we all know our Deus ex-Machina, here, of course.

 Head mounted displays (HMDs) are used, for example, in the field of virtual environments (e.g., virtual reality, augmented reality, the metaverse, or other visual representation of an environment based upon data and which a user can interact).
In such virtual environments, human users may wear HMDs and engage with others in the virtual environment, even though the human users may be physically located remotely from others. In such an environment, a common use case is one where a virtual meeting is taking place (e.g., an office meeting, a class meeting, etc.).
Such a virtual meeting may include, for example, a plurality of audience members wearing a respective plurality of HMDs, and a speaker who is speaking to the audience members or alternatively is presenting information to the audience members. However, present virtual environment systems with HMDs do not provide speakers with highly accurate real time visual cues about audience attention or feelings.
