Virtual and augmented reality devices past, present, and future were the focus of the recent SPIE AR VR MR Conference. Trends in evidence at the conference included a wealth of new innovations in device hardware and optics, using AR to supplement human vision, and the emergence of microLED displays.

Machine vision has begun to overlap with augmented and virtual reality. Not only does machine vision provides pivotal environmental and user information to the AR/VR system, these technologies are also cooperating to enable enterprise operations in industrial manufacturing, assembly, design, and training. New entprise AR/VR applications are bringing together camera systems, near-IR eye tracking, gesture recognition, and other machine vision capabilities.

The start of a new year—especially one with such a nice round number like "2020"—seems to inspire every tech industry publication, column, and anlyst firm to come out with its own Top 10 lists of trends to watch in the coming year, covering both global industries and niche markets. Radiant has saved the time it would take to read all of them by compiling this overview of key themes in some of our core industry areas: IT, displays, AR/VR, and automotive, with links if you want to drill deeper.

To compete with the superior contrast ratio performance of OLED display screens, LCD makers have developed the technique of local dimming, which allows different regions of a backlight to be controlled independently. The introduction of miniLEDs for LCD backlights, especially in full-array configuration, is boosting the performance of LCD televisions and display screens.

MicroLED displays offer superior performance for brightness, contrast, and energy efficiency compared to OLED or other existing display types, but so far production challenges have held them back from mass commercialization. Manufacturers are rapidly closing the gap, however, and microLED display products could be coming to the general consumer market soon. We look at microLED technology and ways to overcome quality challenges.

The development of medical imaging technologies—such as X-ray, MRI, CT, ultrasound, and PET—has revolutionized healthcare. To view images accurately, display screens used by radiologists, surgeons, and other clinicians must provide higher performance than commercial-grade screens. Learn about medical-grade display requirement and quality assurance solutions.

Ever since Princess Leia's holographic emergence in 1977, developers have been trying to create 3D volumetric holograms like those in Star Wars and other science fiction movies. Many of what we call "holograms" today appear three-dimensional, but are actually just images projected onto a flat screen—technically still 2D. But new developments are making 3D holograms that you can view from every angle a reality.

Gestures are a natural and intuitive part of human communication and expression. Thus, being able to use gestures to communicate with devices in our environment has been a goal for technology developers for decades, but it's a complex process. The latest generation of gesture sensing systems include applications in the automotive, medical and consumer spheres, often using three-dimensional / depth sensing based on near-infrared (NIR) light.
