    A ring that lets users 'feel' virtual worlds
    A wearable haptic force-feedback ring with a three-axis force-sensing skin. A) We developed a wearable haptic ring, OriRing, which weighs only 18 g and generates forces of up to 6.5 N. The design incorporates a folding-based prismatic joint, a three-axis force-sensing skin, inkjet-printed bending sensors, SPAs and 3D printed ring frames. B) Force-sensing skin consists of an upper layer with soft pyramid microstructures, a lower layer with four resistive pixels and a spacer separating the two layers. This design enables the detection of both normal and shear forces. C) With its multimodal sensing and actuation capabilities, OriRing renders the size and stiffness of virtual objects through kinaesthetic and proprioceptive feedback...

    Researchers have developed the first megapixel photon-counting camera based on new-generation image sensor technology that uses single-photon avalanche diodes (SPADs). The new camera can detect single photons of light at unprecedented speeds, a capability that could advance applications that require fast acquisition of 3D images such as augmented reality and LiDAR systems for autonomous vehicles.

    “Thanks to its high resolution and ability to measure depth, this new camera could make virtual reality more realistic and let...

    New Tools to Minimize Risks in shared, Augmented-reality environments

    August 22, 2019, Categories  Physics, Technology/Electronics

    For now, augmented reality remains mostly a solo activity, but soon people might be using the technology in groups for collaborating on work or creative projects.

    Security researchers have created ShareAR, a toolkit that lets developers build collaborative and interactive features into AR apps without sacrificing their users’ privacy and security. A few summers ago throngs of people began using the Pokemon Go app, the first mass-market augmented reality game, to collect virtual creatures hiding in the physical world.

    For now, AR remains mostly a solo activity, but soon people might be using the technology for a variety of group activities, such as playing multi-user games or collaborating on work or creative projects...

    Battery-free eye-tracking glasses developed at Dartmouth College could create an even more realistic experience for augmented reality enthusiasts. The new technology improves player controls for gaming and allows for more accurate image displays.

    High power consumption and cost have kept eye trackers out of current augmented reality systems. By using near-infrared lights and photodiodes, Dartmouth’s DartNets Lab has created an energy-efficient, wearable system that tracks rapid eye movements and allows hands-free input of system commands.

    The glasses, which can also h...
