Gallium nitride (GaN)-based light-emitting diodes (LEDs) have transformed the lighting industry by replacing conventional lighting technologies with superior energy efficiency, longer operating life and greater environmental sustainability.

In recent years, considerable attention has been paid to the trend toward miniaturization of LEDs, driven by display devices, augmented reality, virtual reality, and other emerging technologies. Due to the lack of cost-effective native substrates, the presence of high threading dislocation density in heteroepitaxial films grown on sapphire substrate is a major limiting factor for device performance.

In addition, Fresnel reflections at the interface between epitaxy and substrate caused by abrupt changes in the refractive indices of the material reduce the light energy utilization.

As part of the 2024 Prostate Cancer Patient Conference, Dr. Eric Small discusses systemic therapy treatment in advanced prostate cancer, including AR-targeted therapy. The presentation includes definitions of disease states, categories of treatment types, and standards in treatment selection.

AR/VR/MR glasses released in April 2024? i didnt know they were so far along already. Im curious if anyone used these, and impressions of? Still a little bulky, but, my current prediction is this will take over place of cell phones 2029/2030. But, needs to be slimmed down a bit yet; 5 years.

Walmart showed off its use of augmented reality and artificial intelligence in its retail operations. It turns out that AR is leading to better digital sales and cool new applications that haven’t been done before.

The techniques include virtual try-on of outfits, virtual showroom experiences and digital twins, said Desirée Gosby, vice president of emerging technology at Walmart Global Tech, in an interview with VentureBeat.

She emphasized the importance of AR and related technologies for enhancing customer experiences and improve productivity.

And manufacturers are keen to bring additional screens into play, from 2009’s Lenovo’s Thinkpad W700 with its built-in extendable tablet to modern devices like the Asus ZenBook Duo, or Lenovo Yoga Book 9i — and some frankly absurd variants along the way.

But what’s next for the laptop? Will it be Lenovo’s transparent laptop or will AI transform the laptop into handheld devices like how the Steam Deck and ROG Ally X represent a potential reinvention of the gaming laptop? Well, in my opinion, and many others, the next step is augmented reality.

Modern laptops are stuck between two desires, smaller form factors and larger displays. Both of which have their benefits, but you can’t gain more of one without giving up some of the other.

To use the Instagram Chandra experience, search for the “NASAChandraXray” account. Select the effects options (the tab that looks like three four-pointed stars) and select the one you want. Then, you can either save the effect to your camera and apply it to your stories, or you can select the “Try it” button for instant access.

“We are excited to bring data from the universe down to Earth in this way,” Kimberly Arcand, Chandra X-ray Center visualization and emerging technology scientist, said in a statement. “Enabling people to access cosmic data on their phones and through AR brings Chandra’s amazing discoveries literally right to your fingertips.”

Old sunspot region AR 13,664, now renamed AR 13,697, is back. With its re-arrival, can we expect a resurgence of solar activity?

New “metaholograms” could transform AR/VR technologies by enabling crosstalk-free, high-fidelity image projection with vastly increased information capacity.

Researchers have developed a new type of holograms, known as “metaholograms,” capable of projecting multiple high-fidelity images free of crosstalk. This innovation opens doors to advanced applications in virtual and augmented reality (AR/VR) displays, data storage, and image encryption.

Metaholograms offer several advantages over traditional holograms, including broader operational bandwidth, higher imaging resolution, wider viewing angle, and more compact size. However, a major challenge for metaholograms has been their limited information capacity which only allows them to project a few independent images. Existing methods typically can provide a small number of display channels and often suffer from inter-channel crosstalk during image projections.

This innovation has the potential to significantly improve AR/VR displays by enabling the projection of more complex and realistic scenes. It also holds promise for applications in image encryption, where the information is encoded into multiple holographic channels for enhanced security.

The research is a significant step forward in developing high-performance metaholograms with a vastly increased information capacity. This study paves the way for exciting new possibilities in various fields, from advanced displays to information encryption and information storage.
