Some of the most cutting-edge advancements in virtual and augmented reality include:

Haptic Feedback: Haptic feedback technology is increasingly being used to create a more immersive VR and AR experience. This technology allows users to feel physical sensations, such as touch, pressure, and vibrations, while they are interacting with virtual environments.

Eye-Tracking: Eye-tracking technology is becoming increasingly popular in VR and AR devices, allowing users to control the virtual environment simply by looking at objects.

Spatial Computing: Spatial computing refers to the integration of AR and VR with the physical world. With advancements in AR and VR technology, users can now experience more immersive and lifelike environments that blend virtual and physical elements.

Hand and Finger Tracking: Hand and finger tracking technology allows users to control the virtual environment using natural hand movements and gestures.

AI and Machine Learning: AI and machine learning are being used to create more intelligent and interactive virtual and augmented environments. These technologies can be used to create more realistic characters, environments, and interactions.

5G and Edge Computing: 5G technology and edge computing are allowing for faster and more reliable connections, making it possible to stream high-quality VR and AR content.

These advancements are leading to new and innovative VR and AR experiences that are more immersive, intuitive, and interactive.<|im_end|>

With all the advances in VR and AR, why is there still so little use for them?<|im_end|>

There are many reasons for lack of VR and AR popularity, here are some of them:

1. Hardware cost: HMD are expensive, with Meta Quest 2 starting at $400, and other options usually being more expensive.

2. Poor display quality: most headsets experience a "screen door effect", a visual artifact of displays, where the lines separating pixels become visible in the displayed image.

3. Nausea and motion sickness: Latency in displaying image, low FPS, or a drop in FPS, or jittery movement of displayed objects can cause nausea. Driving or walking in VR, when done by controller rather than by physically moving, is known to sometimes produce motion sickness.

4. Poor realism: In order to archive high, stable framerate, many games choose to trade graphics quality for speed, resulting in simplistic, crude models and environment.

4. Weight: VR and AR HMD are heavy, and uncomfortable to wear over long periods of time.

5. Fashion: AR devices are bulky and unfashionable, and the cameras and sensors required for their work are seen as intrusion into privacy.

6. Content: VR and AR are available at affordable price only since very recently, and therefore are young technologies, with a limited amount of content available for them.<|im_end|>
