Researchers have developed a new type of bifocal lens that offers a simple way to achieve two foci (or spots) with intensities that can be adjusted by applying external voltage. The lenses, which use two layers of liquid crystal structures, could be useful for various applications such as optical interconnections, biological imaging, augmented/virtual reality devices and optical computing.

A virtual haptic implementation technology that allows all users to experience the same tactile sensation has been developed. A research team led by Professor Park Jang-Ung from the Center for Nanomedicine within the Institute for Basic Science (IBS) and Professor Jung Hyun Ho from Severance Hospital’s Department of Neurosurgery has developed a technology that provides consistent tactile sensations on displays.

This research was conducted in collaboration with colleagues from Yonsei University Severance Hospital. It was published in Nature Communications on August 21, 2024.

Virtual haptic implementation technology, also known as tactile rendering technology, refers to the methods and systems that simulate the sense of touch in a virtual environment. This technology aims to create the sensation of physical contact with virtual objects, enabling users to feel textures, shapes, and forces as if they were interacting with real-world items, even though the objects are digital.

Researchers at the University of Toronto have found that using virtual and augmented reality (VR and AR) can temporarily change the way people perceive and interact with the real world—with potential implications for the growing number of industries that use these technologies for training purposes.

The study, published recently in the journal Scientific Reports, not only found that people moved differently in VR and AR, but that these changes led to temporary errors in movement in the real world. In particular, participants who used VR tended to undershoot their targets by not reaching far enough, while those who used AR tended to overshoot their targets by reaching too far.

This effect was noticeable immediately after using VR or AR, but gradually disappeared as participants readjusted to real-world conditions.

Optical fiber, as a physical medium for information transmission, is the “highway” of modern economic and social development. However, with the continuous emergence of high-speed and high-capacity communication scenarios such as virtual reality, 5G, intelligent driving, and the Internet of Things (IoT), there is an upper limit to the communication capacity (traffic flow) of the traditional single-mode fiber-optic communication system (highway).

What does the future hold? What will become of this planet and its inhabitants in the centuries to come?
We are living in a historical period that sometimes feels like the prelude to something truly remarkable or terribly dire about to unfold.
This captivating video seeks to decipher the signs and attempt to construct plausible scenarios from the nearly nothing we hold in our hands today.
As always, it will be scientific discoveries leading the dance of change, while philosophers, writers, politicians, and all the others will have the seemingly trivial task of containing, describing, and guiding.
Before embarking on our journey through time, let me state the obvious: No one knows the future!
Numerous micro and macro factors could alter this trajectory—world wars, pandemics, unimaginable social shifts, or climate disasters.
Nevertheless, we’re setting off. And we’re doing so by discussing the remaining decades of the century we’re experiencing right now.

The hippocampus geometrically represents both physical location and abstract variables on a neural manifold in mice performing a decision-making task in virtual reality.

Philosopher and cognitive scientist David Chalmers explores virtual reality and its implication for our understanding of existence. Chalmers examines the simulation hypothesis, challenging conventional views of reality and suggesting that virtual worlds might be as real and meaningful as the physical world. This is a thought-provoking lecture at MindFest, held at Florida Atlantic University, CENTER FOR THE FUTURE MIND, spearheaded by Susan Schneider.
