A new augmented reality system places virtual objects within real-world backgrounds on cell phone screens and lets people interact with those object by hand as if they were really there.
Virtual-reality researchers have developed a virtual-walking system that records a person's walking and re-plays it with vision and foot vibrations. Psychological experiments showed that the sensation of walking and telepresence from the oscillating visual flow combined with foot vibrations is stronger than without vibrations. The system can reconstruct the experience of walking to people who are a distance away, or who have a disability that may impair walking in the future.
We may listen to facts from Siri or Alexa, or directions from Google Maps or Waze, but would we let a virtual agent enabled by artificial intelligence help mediate conflict among team members? A new study says not just yet.
Engineers have solved a 50-year-old puzzle in signal processing. They've formulated the 'inverse chirp z-transform,' an algorithm related to one that's running on your cell phone right now. It took some computing power and some math expertise to do it.
Using virtual, cloud-based, interconnected computing techniques applied to 51,000 variables, researchers reduced the time needed to assess a cancer patient's tumor profile and suitability for clinical trials from 14 to 4 days. This method also increased two-fold, over a four-year period, the number of cases that could be assessed compared to conventional methods.
Scientist describe a new algorithm that combines the capabilities of two spacecraft instruments, which could result in lower cost and higher efficiency space missions. The virtual 'super instrument,' is a computer algorithm that utilizes deep learning to analyze ultraviolet images of the Sun and measure the energy that the Sun emits as ultraviolet light.
One of the biggest challenges to implementing interprofessional education for health professions students is scheduling. Could virtual reality education help? A small new study focused on palliative care, says yes.
Researchers have invented an algorithm that produces a real-time portamento effect, gliding a note at one pitch into a note of another pitch, between any two audio signals, such as a piano note gliding into a human voice.
Scientists have developed a soft artificial skin that provides haptic feedback and -- thanks to a sophisticated self-sensing mechanism -- has the potential to instantaneously adapt to a wearer's movements. Applications for the new technology range from medical rehabilitation to virtual reality.
Animating human hands has long been considered one of the most challenging problems in computer graphics. That's because it has been impossible to capture the internal movement of the hand in motion -- until now. Using magnetic resonance imaging (MRI) and a technique inspired by the visual effects industry, researchers have developed the world's most realistic model of the human hand's musculoskeletal system in motion. Applications include computer graphics, prosthetics, medical education, robotics, virtual reality.
Scientists prove a well-known model of material behavior applies to high-temperature superconductors, giving them a new tool for understanding how these materials conduct electricity with no loss. Simulations suggest we might be able to toggle superconductivity on and off in certain materials by tweaking their chemistry so electrons hop from atom to atom in a particular pattern - as if hopping to the atom diagonally across the street rather than to the one next door.
A new study has shown that an interactive avatar, which gives both instructions and feedback on the attention of the learner, can improve the performance of ADHD children on a complex problem-solving task.
A research team is developing a smart skin inspired by the cephalopod which can be used in 3D displays, as interfaces for the visually impaired, and to help reduce drag on marine vehicles.
Engineers have developed a new augmented reality (AR) head-mounted display (HMD) that delivers a realistic 3D viewing experience, without the commonly associated side effects of nausea or eyestrain.
Since "2001: A Space Odyssey," people have wondered: could machines like HAL 9000 eventually exist that can process information with human-like intelligence? Researchers say that true, human-level intelligence remains a long way off, but a new article explores how computers could begin to evolve learning in the same way as natural organisms did -- with implications for many fields, including artificial intelligence.
Applications like web browsers or smartphone apps often use a lot of memory. To address this, a research group has developed a system they call Mesh that can automatically reduce such memory demands.
A new study suggests employee safety could be improved through use of virtual reality (VR) in Health and Safety training, such as fire evacuation drills. Researchers developed an immersive VR system to stimulate participants' perception of temperature, and senses of smell, sight and hearing to explore how they behaved during two health and safety training scenarios.
Researchers have developed a computer model that can translate text describing physical movements directly into simple computer-generated animations, a first step toward someday generating movies directly from scripts.
Researchers have developed a cheaper and more efficient method for Internet-of-Things devices to receive high-speed wireless connectivity.
Researchers have demonstrated promising results in reducing secondary cardiac events and re-hospitalizations by creating a virtual cardiac rehabilitation program that fits seamlessly into patients' lives. Increasing rates of program enrollment and completion have been key factors in the improved outcomes.
