Meta releases image segmentation model Segment Anything
Keywords: image segmentation, fully convolutional neural network, generative AI, artificial intelligence
Facebook recently released an image segmentation model called “Segment Anything”, which can be seen as a GTP in the field of image segmentation to some extent, as it can accurately segment any object in an image through simple prompts, such as people, cars, trees, etc.
Technically, Segment Anything uses a fully convolutional neural network, which can perform pixel-level segmentation of images, and thus can handle images of different sizes and shapes, and can perform accurate segmentation in different scenarios. Compared with traditional methods, fully convolutional neural networks perform better in terms of segmentation effects and accuracy.
In addition, Segment Anything supports a method called “fuzzy processing” for data annotation, which allows annotators to only annotate part of the area to obtain annotation information for the entire image. This method can greatly improve annotation efficiency while reducing the workload of annotators.
In addition, Segment Anything also has the following advantages:
- Can adaptively adjust model parameters according to data characteristics to make model segmentation results more accurate;
- Can introduce multiple prompt signals so that the model can segment different types of images;
- Can handle more complex image scenes such as medical images, urban street scenes, etc;
- Supports active learning and other functions to help users annotate data more efficiently;
- Provides a tool called “data annotation engine” to improve efficiency in large-scale data annotation.
Therefore, Segment Anything can not only improve the efficiency of data annotation, but also improve the accuracy of annotation and the utilization of data.
Meta provided some real-world use cases of using Segment Anything. For example, SAM can be used in AR glasses to identify everyday objects, send reminders and instructions to users. SAM can also help farmers or assist biologists in research in the agricultural field, assist autonomous driving, and so on.

LumaAI releases Unreal plugin
Keywords: game engine, photogrammetry, neural radiance fields, volumetric rendering
Recently, Luma AI released the first version of the UE 5 (Windows) plugin. This plugin uses locally running volumetric rendering — which means no longer needing to use traditional mesh, geometry, material-based 3D models for rendering. According to user testing, the plugin only needs an RTX2060 graphics card with 6G VRAM to run smoothly.
Luma is a mobile app that uses NeRF (Neural Radiance Fields) technology to reconstruct 3D objects or scenes. Simply put, Luma uses NeRF for photogrammetry, friendly interface guidance, good reconstruction results, and generating videos using reconstructed models are its important features. It also supports exporting in multiple formats: obj, gltf, usdz, ply. With the release of this UE5 plugin, LumaAI also supports exporting to Luma Field File and importing into UE5 for direct volumetric rendering.
The process has 5 steps:
- Download the sample project and unzip
- Double click the
.uprojectfile to open UE5 - Download your own Luma Field file (need to use Luma App for photogrammetry in advance)
- Drag the downloaded file into the Content Browser in Unreal Editor
- Wait a few seconds, a Unreal blueprint will be generated based on the NeRF file, drag it into UE5 to use
Luma officially stated: For plugins support for other 3D engines and 3D software, it will be released after the UE5 plugin is good enough. So versions for Unity and Blender still need to wait.
NeRF was first applied in novel view synthesis. Due to its powerful ability to implicitly represent 3D information, it rapidly developed in the direction of 3D reconstruction. Compared to traditional photogrammetry algorithms, it can generate 3D models with no holes and higher surface quality.
The data generated directly by NeRF is in voxel format, which is like a bunch of small spheres of different colors. To use it in 3D games or VR, it needs to be converted to traditional Mesh model format. With the release of this UE5 plugin, no format conversion is required, and volumetric rendering can be performed directly in UE5.
Currently on the market, mobile apps that use NeRF technology for photogrammetry also include Epic Games’ RealityScan, which is Unreal Engine’s own NeRF service, but does not yet support exporting and using volumetric rendering.
OpenXR Toolkit adds support for eye tracking on Meta Quest Pro
Keywords: Meta Quest Pro, eye tracking, OpenXR
Since March 2022, OpenXR Toolkit has supported eye tracking rendering plugins with eye tracking for Varjo Aero and Pimax. It now adds support for Quest Pro.
OpenXR Toolkit is a free and open source project by Microsoft employee mbucchia, bringing new capabilities not natively supported to OpenXR-based PC VR apps, like AI image upscaling, hand tracking, static and dynamic foveated rendering, and more.
Eye tracked foveated rendering (ETFR) is an emerging technology. It only renders the small area where the eyes are currently looking at full resolution, while the rest is rendered at lower resolution. This technique can greatly boost performance in games, as the freed up GPU resources can be used to increase performance, push rendering resolution, or dial up graphical settings. Eye tracking tech also allows for more natural head movement in games, enabling players to better immerse themselves. In summary, eye tracking is a very promising technology, and OpenXR Toolkit’s support will bring better gaming experiences to more players.
OpenXR is an open standard provided by Khronos to simplify AR/VR development by enabling developers to seamlessly target a wide range of AR/VR devices. The Khronos Group has been working to unify the fragmented state of XR without standards. Currently, Meta, Sony, Valve, Microsoft, HTC, NVIDIA and AMD have all embraced this standard.

In addition to smart glasses, virtual reality (VR) and augmented reality (AR) technologies also have many potential applications in healthcare. Medical students and interns can use VR for immersive simulation of surgeries and clinical practice to enhance their skills and confidence. Additionally, AR can provide real-time guidance and cues for doctors to facilitate diagnosis and treatment.
VR can help patients distract from pain and discomfort. Studies show VR can reduce pain after surgery and minimize the need for pain medication. VR can also treat psychological conditions like anxiety, depression and PTSD by providing immersive experiences to help patients learn coping and emotional regulation skills. AR can offer real-time feedback and guidance to help patients make correct motions and postures for rehabilitation.
VR and AR have enormous potential in healthcare, benefiting doctors with improved diagnosis and treatment, while helping patients better manage diseases and recover health.

Jim Henson’s The Storyteller: Taking the reading experience to the next level with AR
Keywords: AR, creativity, reading, concept video
https://youtu.be/LKH1lwbrUJE?si=rRRQx1pFE2aBZXd8
Electronic devices and physical books don’t have to be completely conflicting. In the eyes of Felix & Paul Studios — an Emmy Award-winning creator, the two can even complement each other.
In this video, Felix & Paul Studios introduces how to use augmented reality (AR) technology to enhance the reading experience. By adding AR markers to printed materials, readers can use AR glasses to “see” these books in a different way. When readers open the book, the castles in the book can be presented as 3D models, accompanied by vivid animations and realistic sound effects, allowing readers to immerse themselves in the book’s scenes.
Based on this concept, AR glasses can enable even more realistic interactions, such as in the video, when the reader reads a scene full of seawater, the seawater in the book also flows out as the reader tilts the book. The realism is quite impressive.

Before Your Eyes — A Beautiful VR Narrative Art Showcase
Keywords: PlayStatation VR2, VR games
“Before Your Eyes” is a game originally released on PC in 2021, on mobile last year, and now debuts on PlayStation VR2. Players take on the role of a child named Benny, going through memories of his upbringing, family life, and exploring his artistic talents. Interaction happens by blinking, and manipulating objects seen in memories, including flipping pages, playing piano, and drawing.
Blinking may also cause players to miss interaction opportunities. When a metronome icon appears in a memory, it signals the next blink will jump to another scene, but you don’t know how far. Sometimes during dialogues, the small metronome also shows up, meaning you may accidentally truncate a memory midway from blinking, thus missing some scenes. While annoying, this also adds to the dreamlike quality of the game, just like real memories where you can’t recall certain parts.
This is an extremely compelling VR narrative that allows players to experience the emotions within the story first-hand.
Making Cosmonious High Accessible for Blind and Low Vision Users
Keywords: accessible gaming, vision, touch, blindness
Owlchemy Labs is committed to creating virtual reality games for everyone, as stated in their Accessibility Statement pledging ongoing efforts in this area. They have previously prioritized major advances in accessibility, like subtitles, physical and height accessibility, as team initiatives. They encourage every developer to consider accessibility in their creations, and proactively incorporate accessible features on launch and in updates.
Their latest addition of various accessibility options in Cosmonious High, including single-controller mode, seated mode, subtitles, etc, shows their continued exploration into accessible gaming. A product that can only be played by audiences without any disabilities is considered incomplete. They constantly push new frontiers through research, testing and collaborations to ensure the widest possible audience can play games.
Emphasized is that developing games for blind and low vision players is more than just adding audio cues and options. Blindness is a spectrum, so fully accommodating blind and low vision players also considers touch and residual vision.
To achieve this, they added more haptic feedback that helps identify objects when selected, critical for puzzle solving and tasks. Players can feel the shapes when choosing.
Additionally, high contrast object outlines were implemented. Silhouetting key objects makes them more visible, and understandable through haptic feedback on selection.
