What are the negative effects of virtual reality?
While virtual reality (VR) has many potential benefits, such as enhancing education, entertainment, and even therapy, there are also several negative effects associated with its use. One of the most common negative effects of virtual reality is motion sickness, which can occur when the brain perceives conflicting signals from the body and the VR environment. This can cause nausea, dizziness, and disorientation. Another potential negative effect of virtual reality is addiction. Some users may become so immersed in the virtual world that they lose touch with reality and become dependent on the experience. This can lead to social isolation, neglect of responsibilities, and even physical harm. Virtual reality can also have negative effects on physical health. Extended use of VR headsets can cause eye strain, headaches, and neck pain. In addition, some VR games and experiences may require physical movement or exertion, which can lead to injuries or muscle soreness. Finally, there are concerns about the psychological effects of virtual reality, particularly on young children and adolescents. Some experts worry that prolonged exposure to virtual environments could lead to behavioral changes, desensitization to violence, and even increased aggression. Overall, while virtual reality has many potential benefits, there are also several negative effects to consider, particularly in terms of physical and psychological health. It is important for users to be aware of these risks and to use virtual reality in moderation.
Hand Gestures not working on HoloLens 2
Hi folks, I created an MR application on HoloLens 2 and was working fine. One day, the device went to sleep when the application was running and when i turned on the device again, the hand gestures (scaling, positioning and rotating) are not working at all. And also, the issue occurred on every app i made with Unity before. I did factory reset on the device and even then its not solved. I have two HoloLens with me and both of them are having this hand gestures issue now. I'm in a desperate situation. Please help me out with a solution for this...HoloLens 2 + Mixed Reality Applications | Technical Datasheet

Establishing an absolute world coordinate system
I am currently working on a project using the HoloLens 2, where I create a primitive that offsets a spatial anchor in a certain direction and distance received from a client socket I have in my scene. However, I am having problems with the coordinate system. Each time I open the application on the HoloLens, the coordinate system changes based on the direction I am standing since the headset is always taken as the origin. I am struggling to figure out how to establish an absolute coordinate system that I can use and stay consistent inbetween scenes. I was looking at the MRTK documentation and found the World Locking Tool (WLT), and I am curious if this may be my solution. I was curious if anyone else has experience with WLT, especially for this type of application, or knows another possible way to establish an absolute coordinate system between sessions. This is where I was looking for the WLT -https://learn.microsoft.com/en-us/windows/mixed-reality/develop/unity/spatial-anchors-in-unity?tabs=wltMixed Reality Mastery: HoloLens 2 & 3D Worlds Challenge

Hi ! I'm doing my bachelor project with the Microsoft Hololens 2, specifically I'm doing a technical analysis regarding the different toolkit/plug-ins/software available for doing collaboration (not remote collaboration but local). I'm especially looking for some that work with unity as this is the software I'm using to build/deploy my applications on the Hololens. Here's is some of my research, if you have comment regarding it or you maybe think that it can be good to add something I would gladly discuss it with you. As you see did find all unity supported plateforms, so even if it's not for unity I will gladly take your recommandation. Best regards

Hi, I was trying to explore Azure Spatial Anchors Capabilities for shared experience, and I'm following this https://learn.microsoft.com/en-us/azure/spatial-anchors/tutorials/tutorial-share-anchors-across-devices?tabs=azure-portal%2CVS%2CUnityHoloLenslink for understanding the things. As given in the link when I clone thishttps://github.com/Azure/azure-spatial-anchors-samples project and I try to open the unity project from Unity folder I get the following errors. Can someone help me how to get started. And If I Enter Safe Mode, It gives me following errors: Thank you
CloudSpatialAnchor problem on ARFoundation
I'm creating a HoloLens app using Azure Spatial Anchors in Unity. All is good when creating, uploading and retrieving spatial anchors. But when trying to apply the spatial anchor to the scene object via the CloudNativeAnchor.CloudToNative method, I get this exception: "InvalidOperationException: Could not find an ARAnchor associated with the CloudSpatialAnchor" I tried calling gameObject.FindOrCreateNativeAnchor (which to my understanding creates an ARAnchor if there isn't one already) before calling CloudNativeAnchor.CloudToNative but the exception persists. Any help is much appreciated! I'm on these versions: Unity 2020.3 ASA SDK 2.11.0 Mixed Reality OpenXR Plugin 1.2.1 ARFoundation 4.1.7 (edited)
