Experiments in vision science typically use display technologies such as CRTs or LCDs to present stimuli to observers. With careful calibration, these stimuli can be presented very precisely in order to test specific processes in the visual system. Their limitations come from their characteristics including dynamic range, gamut, and resolution. Conventionally, stereoscopic displays are used for vision experiments involving in 3D perception. However, they not only inherit the issues of 2D displays but also restrict the range of vision experiments, which can be done for interactive and immersive cases. These limitations place constraints on the properties of stimuli that are presented on standard displays.

Over recent years a number of new technologies have been developed that extend the capabilities of displays to be more realistic and more immersive. This joint webinar between the Applications of Visual Science and Display Technology Technical Groups, will present three novel display technologies. These will include a high dynamic range, multi-primary display for extending the output range to more faithfully represent the real world, a volumetric display for 3D object presentation and an immersive light-field display for placing the observer in a 3D scene. Talks will give an introduction to how each technology works, what their capabilities are and consider how they might be used in vision science research.

About the Presenters:

Allie C. Hexley, University of Oxford

Allie C. Hexley is currently completing her D.Phil. in Experimental Psychology at the University of Oxford, UK, supported by a Marie Skłodowska-Curie Innovative Training Network Fellowship as part of the RealVision consortium, under the European Union’s Horizon 2020 research and innovation program. She received her B.Sc. in Physics and Brain & Cognitive Sciences from MIT in 2017 and has combined her interests in physics and neuroscience in her current work on visual perception. Her work follows a multi-disciplinary approach, integrating methodology in psychophysics, genetics, retinal imaging, and simulation alongside the development of new display technologies and metrics, to enable novel investigations of human vision.

 

Ryuji Hirayama, University College London

Ryuji Hirayama completed a PhD at Chiba University in Japan followed by postdoctoral research at the University of Sussex, before joining University College London as a research fellow. Ryuji’s research interests include the development of novel 3D interfaces such as free-space volumetric displays and holography. Ryuji’s more recent research has been in the development of a realistic multimodal volumetric display using phased array transducers. By using ultrasound to directly control matter in the real world, animated visual, auditory and haptic content can be created. This work was published in Nature in 2018 and received international media interest, likening it to a ‘Star Wars-style projection’ based on its ability to create 3D images that hover in mid-air.
