News industrie : The fashion and luxury industries have done all they can to avoid missing out on the metaverse. But as these virtual worlds are struggling to find their audience, the hope of making a return on their investments is low. (#1566935)

Decentralized systems will be the default for metaverse and AI use cases for identity, KuppingerCole analyst Mike Neuenschwander argues. Blockchain can empower individuals to own their digital identities and have control over their own data. Centralized approaches to authentication, identity, and security aren’t going to have the scalability that a decentralized approach would have..

Virtual Reality has emerged as a valuable tool in medical education, primarily for teaching basic sciences and procedural skills. However, its potential in clinical psychiatry, particularly in comprehending the subjective experiences of individuals with mental illness, remains largely untapped. This paper aims to address this gap by proposing a phenomenological-driven approach to the design of virtual reality in psychiatry education. Insights into psychopathology, which involves the systematic study of abnormal experiences as well as self-awareness on behalf of the clinician, demands training. The clinician must develop sensitivity, observational skills, and an understanding of patients’ subjective experiences. While integrating the subjective perspective and promoting emotional self-awareness in psychiatry education have been recommended, further research is necessary to effectively harness virtual reality for this purpose. Drawing from the convergence of virtual reality, phenomenological approaches to grasping subjectivity and psychopathology, this paper aims to advance teachings in psychopathology. It underscores the importance of integrating biomedical knowledge with the lived experiences of psychiatric patients to offer learners a comprehensive understanding of clinical psychiatry. This approach is deeply rooted in the theories of three influential figures: Karl Jaspers, a German psychiatrist and philosopher, who emphasized the role of phenomenology in clinica

Functional MRI studies show how blue light can enhance cognitive performance by modulating information flow through the brain
"Light is critical for transmitting visual information to the brain; but light also impacts non-visual processes in the body, such as circadian rhythms, hormone secretion, pupil size and sleep cycles. Exposure to blue light is known to stimulate alertness and enhance cognitive performance, but the neural processes underlying this effect are not well understood. Now, researchers at the University of Liège in Belgium have used ultrahigh-field MRI to find out more about how light stimulates our brains, reporting their findings in Communications Biology.

Sega was founded by American businessmen Martin Bromley and Richard Stewart as Nihon Goraku Bussan[b] on June 3, 1960. Shortly after, the company acquired the assets of its predecessor, Service Games of Japan. In 1965, it became known as Sega Enterprises, Ltd., after acquiring Rosen Enterprises, an importer of coin-operated games. Sega developed its first coin-operated game, Periscope, in 1966.  Periscope[a] is an electro-mechanical arcade shooting submarine simulator

More than a decade after the 2011 Fukushima nuclear disaster, much of the areas remained unexplored. Some of the doors to rooms in the facility had not been opened since the disaster, and officials had little idea what was on the other side. But in 2022, decommissioning crews began using Spot, the quadruped robot from Boston Dynamics, to collect data, shoot video, measure radiation dose, and gather debris samples for radiation testing. Although officials were already using other tracked and wheeled robots, the superior mobility and the automated arm of Spot proved to be “game changers,” says Brad Bonn, head of nuclear programs for Spot."

The conventional top-down technology uses dry etching to define the LED size, leading to damage to the LED side walls. Since sizes of microLEDs approach the carrier diffusion length, the damaged side walls play an important role, reducing microLED performance significantly from that of large area LEDs. In this paper, we review our efforts on realization of microLEDs by direct bottom-up growth, based on selective area metal–organic vapor phase epitaxy. The individual LEDs based on either GaN nanowires or InGaN platelets are smaller than 1 μm in our approach. Such nano-LEDs can be used as building blocks in arrays to assemble microLEDs with different sizes, avoiding the side wall damage by dry etching encountered for the top-down approach. The technology of InGaN platelets is especially interesting since InGaN quantum wells emitting red, green and blue light can be grown on such platelets with a low-level of strain by changing the indium content in the InGaN platelets. This technology is therefore very attractive for highly efficient microLEDs of three primary colors for displays.

"Various systems and techniques for intuitively and non-obstructively obtaining awareness of fellow collaborator views and/or statuses in an augmented reality environment are disclosed. An interaction is detected between a first and second HMD, both collaborative participants of a shared dataset represented in an augmented reality environment. The detected interaction can cause the first HMD to request state information associated with the second HMD. The second HMD can process the request in accordance with a privacy policy to generate a set of visual data as a response to the request. The second HMD can communicate the generated set of visual data to the first HMD, such that the first HMD can render the received set of visual data as additional computer-generated object(s) to be displayed concurrently with its own augmented view. The additional computer-generated object(s) can be positioned in accordance with a real-world or virtualized position of the second HMD, such that the now-visible state information associated with the second HMD does not obstruct a view of the second HMD's user."
