NoctuaXR: Enhancing Video See-Through Perception for XR in Low-Light Environments with Real-Time Ambient-Aware
IEEE Transactions on Visualization and Computer Graphics
|April 6, 2026
Summary
NoctuaXR enhances Video See-Through (VST) in Extended Reality Head-Mounted Displays (XR HMDs) for better low-light visuals. This technology improves color accuracy and task efficiency, making XR more practical for daily use.
Area of Science:
- Extended Reality (XR)
- Human-Computer Interaction
- Computer Vision
Background:
- Video See-Through (VST) in XR Head-Mounted Displays (HMDs) enables real-world perception with integrated virtual content.
- Current VST technology suffers from low visual fidelity, particularly in low-light conditions.
Purpose of the Study:
- To introduce NoctuaXR, an environment-aware enhancement for VST systems.
- To significantly improve visual quality and user experience in low-light scenarios.
Main Methods:
- Developed NoctuaXR, a lightweight and low-cost enhancement.
- Implemented real-time, pixel-level adjustment of brightness and saturation based on ambient light.
- Conducted perceptual quality and daily task performance evaluations.
Main Results:
- NoctuaXR improved color accuracy by 68.59% in a 10 lx environment compared to Baseline.
- Outperformed the Varjo XR-4 Focal Edition by 64.26% in low-light visual quality.
- Enhanced task efficiency to a level comparable to high-end XR HMDs.
Conclusions:
- NoctuaXR effectively addresses VST limitations in low-light environments.
- The enhancement offers a practical solution for improved XR usability in diverse real-world applications.
- NoctuaXR demonstrates tangible value in making XR technology safer and more convenient for daily life.

01:15Depth Perception and Spatial Vision
2.7K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

02:16Light Acquisition
9.9K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

01:12Perceptual Constancy
1.8K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

01:16Focusing of Light in the Eye
7.5K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

01:24Color Vision
1.9K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

01:22Photoreceptors and Visual Pathways
11.1K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...
