Optogenetics has emerged as an exciting tool for manipulating neural activity, which in turn, can modulate behavior live organisms. However, detecting the response to optical stimulation requires electrophysiology with physical contact or fluorescent imaging at target locations, is often limited by photobleaching and phototoxicity. In this paper, we show that phase report intracellular transport induced optogenetic stimulation. We developed a multimodal instrument both stimulate cells...

Augmented reality (AR) devices seek to create compelling visual experiences that merge virtual imagery with the natural world. These often rely on wearable near-eye display systems can optically overlay digital images left and right eyes of user separately. Ideally, two should be shown minimal radiometric differences (e.g., same overall luminance, contrast, color in both eyes), but achieving this binocular equality challenging stringent demands weight size. Basic vision research has a...

To obtain a single percept of the world, visual system must combine inputs from two eyes. Understanding principles that govern this binocular combination process has important real-world clinical and technological applications. However, most research examining relied on relatively simple stimuli it is unclear how well findings apply to scenarios. For example, well-known that, when eyes view sine wave gratings with differing contrast (dichoptic stimuli), often matches higher grating. Does...

Near-eye display systems for augmented reality (AR) aim to seamlessly merge virtual content with the user’s view of real-world. A substantial limitation current is that they only present over a limited portion natural field (FOV). This reduces immersion and utility these systems. Thus, it essential quantify FOV coverage in AR understand how maximize it. It straightforward determine monocular based on system architecture. However, stereoscopic 3D create more complicated scenario because two...

Abstract Head‐mounted displays (HMDs) for virtual and augmented reality applications could have severe nonuniformities due to complex optical components the choice of light source technologies. In addition, module variations between two eyes can result in different colors being seen with left right eyes. Binocular rivalry is expected large color differences eyes, which severely affect product usability. Thus, it important characterize predict binocular HMDs caused by interocular differences....

We aimed to develop a paradigm that can efficiently characterize motion percepts in people with low vision and compare their responses well-known misperceptions made by typical when targets are hard see.

Many extended reality (XR) devices present different views to the left and right eyes. Unwanted colorimetric differences between these can cause perceptual artifacts that degrade binocular image quality. We an image‐computable model designed predict appearance of with in XR displays. The is fitted data from a recent study which people provided multidimensional responses about stimuli simulating optical see‐through augmented device interocular intensity differences.

We propose a novel computational super-resolution imaging technique, coded aperture based on compound eye camera array, which is to reverse the aliasing information by introducing four different modulations.

Dichoptic tone mapping methods aim to leverage stereoscopic displays increase visual detail and contrast in images videos. These methods, which have been called both binocular dichoptic enhancement, selectively emphasize differently the two eyes' views. The system integrates these differences into a unified percept, is theorized contain more overall than each eye's view on its own. As become increasingly common for augmented virtual reality (AR/VR), an appealing technique imaging pipelines....

Abstract The purpose of this study was to assess the attitudes health education professors toward persons with AIDS, and compare findings similar data from previous studies assessing physician medical student AIDS. Attitudes individuals described in a vignette were elicited 256 randomly selected professors. Subjects received one four vignettes plus survey prejudice, social interaction, interpersonal characteristics. Vignettes differed only illness being either AIDS or leukemia, sexual...

In chronic lung/airway disease, there is often a combination of systemic inflammation with an airway/lung‐mediated exacerbation. Under these conditions, patients may experience bouts acute hypoxia; however, to date, limited information regarding the influence this paradigm, including its accompanying neuroinflammation, on hypoxic ventilatory response (HVR). To begin address issue, we used ‘two‐hit’ lipopolysaccharide (LPS) administration protocol in which LPS (ip, 3 mg/kg) was administered...

Autonomous rail rapid transit (ART) is a new type of multiunit, articulated, rubber-wheeled urban transport system. The noise sources ART have significant time-varying characteristics. It unsuitable to track the error signal by installing too many sensors, which poses challenge in active control ART. Thus, this paper proposes convolutional fuzzy neural network-based cancellation approach without sensors solve problem. proposed utilizes network (CNN) extract characteristics and trains...

Our ability to locate and identify objects in the surrounding environment supports a variety of tasks, such as guiding eye movements directing attention. However, differentiating figural content animals from their surroundings (figure-ground segregation) is challenging natural environments that are cluttered with shapes, textures, edges. Recent work suggests neurons middle-temporal cortex (area MT) support figure-ground segregation motion dynamic environments, but principles underlying these...

Digital reproductions often aim to recreate the visual experience of viewing a physical scene. Current reproduction pipelines are limited by luminance dynamic range typical cameras and displays, which is much narrower than many scenes. Thus, reproducing contrast detail in way that replicates scene challenge, requires mapping high content lower via tone algorithms. However, because lossy process, it can compromise visibility perceptual realism. It has recently been suggested binocular vision...

Binocular vision requires combining two eye’s views into a single percept of the world. The rules that govern binocular combination can be studied by showing people dichoptic stimuli (stimuli have differing appearance in eyes) and using an adjustment task to identify most closely matching non-dichoptic stimulus. However, oftentimes perception is unique experience challenging precisely match. A common example this rivalry experienced when viewing orthogonally oriented gratings eyes. While...

The visual system is tasked with combining the two eye’s views into a single percept of world. To understand principles that underlie this combination, dichoptic stimuli (stimuli have different levels luminance and/or contrast in eyes) can be used to probe how each input contributes ultimate binocular percept. For example, perception simple stimuli, such as sine wave gratings, well-predicted weighted combination eyes inputs typically biased towards eye seeing higher contrast. We aimed...
