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.

Lenses are used to bend and focus light. Normal lenses rely on their curved shape to achieve this effect, but physicists from the University of Amsterdam and Stanford University have made a flat lens of only three atoms thick which relies on quantum effects. This type of lens could be used in future augmented reality glasses.

The findings have been published in Nano Letters (“Temperature-Dependent Excitonic Light Manipulation with Atomically Thin Optical Elements”).

The thinnest lens on Earth, made of concentric rings of tungsten disulphide (WS2), uses excitons to efficiently focus light. The lens is as thick as a single layer of WS2, just three atoms thick. The bottom left shows an exciton: an excited electron bound to the positively charged ‘hole’ in the atomic lattice. (Image: Ludovica Guarneri and Thomas Bauer)

Chinese scientists have developed a new type of lens that can be used for health care and augmented reality (AR). Based on radio frequency, the eye-tracking smart contact lenses don’t require battery or conventional silicon chips and are biocompatible and imperceptible.

Set to be used for human-machine interaction (HMI), the smart contact lenses rely on tracking eye movements. The lenses use methods like pupil center corneal reflection and electrooculography (EOG) to track eye movements.
