Imagine being able to build and use a robotic device without the need for expensive, specialist kit or skills. That is the vision that researchers have now turned into reality, creating a lightweight, affordable and simple solution for everyday users.
Read moreA 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.
Read moreEngineers 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.
Read moreResearchers have found that steps measured through a step tracker worn on the wrist can be used to estimate exercise capacity and determine the health status of patients, rather than the standardized 6-minute walk distance test, which is usually conducted in a clinical setting.
Read moreThe complex interplay among the arteriovenous grafts, the vessels they connect, and the blood they transport has been difficult to simulate, but one new method provides a way. Researchers report simulations that reconstructed the fluid dynamics affected by the insertion of an AVG. They used a model that considered the ability of AVG tubes and blood vessels to deform and found much of the disrupted flow could be mitigated by this flexibility.
Read moreScientists 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.
Read moreAnimating 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.
Read moreEngineers 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.
Read moreA new study has found that using three-dimensional virtual reality models to prepare for kidney tumor surgeries resulted in substantial improvements, including shorter operating times, less blood loss during surgery and a shorter stay in the hospital afterward.
