MRTK 3 Pinch Recognition On HoloLens 2
Hi everyone, this is my first time posting here. Please let me know if I messed up something in this post. I am optimizing a HoloLens 2 application developed with MRTK 3 in Unity, and I have been trying to improve the sensitivity of pinch recognition. In other words, what I wish to achieve is that the object manipulators in the application are only activated by pinching when the user’s thumb-forefinger distance becomes 0 (or at the least very close to 0). I set the pinch open threshold and the pinch closed threshold of the hands aggregator subsystem of MRTK 3 to 0.08 and 0.03, hoping that MRTK 3 will only recognize pinch in the more sensitive way mentioned above. However, the object manipulators are still activated by pinching even when the user’s thumb and forefinger are quite far away (about one half of the length of the user’s forefinger) from each other. Is this because of the hardware limitation of HoloLens 2? Is there any possibility that I can improve the pinch recognition on HoloLens 2? Big thanks in advance!
The Growing Potential of Mixed Reality in the Tech Community
Mixed Reality (MR) is rapidly becoming one of the most exciting and transformative technologies in the tech community, blending the physical and digital worlds to create immersive, interactive experiences. As MR technology continues to evolve, it is unlocking new possibilities across various industries, from gaming and entertainment to education, healthcare, and beyond. One of the most significant impacts of Mixed Reality is its ability to enhance user interaction with digital content. Unlike Virtual Reality (VR), which immerses users in a completely virtual environment, or Augmented Reality (AR), which overlays digital information onto the physical world, MR allows users to interact with digital objects as if they were part of the real world. This seamless integration creates opportunities for more intuitive and natural user experiences, whether it’s manipulating 3D models in real-time, collaborating with remote colleagues using holograms, or visualizing complex data in a more meaningful way. The tech community is already seeing the potential of MR in areas such as training and simulation. For example, in healthcare, MR can be used to simulate surgeries, allowing medical professionals to practice procedures in a risk-free environment. In education, students can explore historical sites or complex scientific concepts through interactive, lifelike simulations, making learning more engaging and effective. The ability to create such immersive experiences is transforming how we approach problem-solving, learning, and skill development across various fields. Moreover, Mixed Reality is opening new doors for creativity and innovation in design and entertainment. Designers and artists can use MR to create and interact with 3D content in ways that were previously impossible, allowing for more dynamic and collaborative creation processes. In the entertainment industry, MR is pushing the boundaries of storytelling, enabling audiences to step into their favorite stories and interact with characters and environments in ways that were once the stuff of science fiction. As the technology behind Mixed Reality continues to advance, with improvements in hardware, software, and connectivity, the barriers to entry are gradually being lowered. This democratization of MR technology means that more developers, creators, and businesses can experiment with and adopt MR solutions, driving further innovation and expanding the ecosystem. The tech community plays a crucial role in this evolution, as developers and engineers work together to create new tools, frameworks, and platforms that make MR more accessible and scalable. However, the rise of Mixed Reality also presents new challenges, particularly in terms of content creation, user experience design, and ethical considerations. How do we ensure that MR experiences are accessible and inclusive? What are the implications for privacy and security as MR becomes more integrated into our daily lives? These are critical questions that the tech community will need to address as Mixed Reality becomes more pervasive. In conclusion, Mixed Reality represents a significant leap forward in how we interact with digital content and the physical world. Its potential to revolutionize industries and enhance human experiences is vast, and as the tech community continues to explore and develop this technology, we can expect to see even more groundbreaking applications emerge. Whether you're a developer, designer, or enthusiast, the Mixed Reality space offers endless opportunities to innovate and shape the future. Click Here
Unity App Stuck Loading On HoloLens 2
I am following this document andthis tutorialto test AR on a HoloLens 2, and I go to the part where I have a Unity game with all the proper setup (ie. build settings are correct, I used Unity AR feature tool, etc.) and with 2 squares. I built the project and opened the solution, and then I set the configuration to "Release," platform to "ARM64," and set it to "Device" because I have the HoloLens directly connected to my laptop. I selected the Unity app solution and right-clicked it to "Set as Startup Project." Then, I pressed the green button next to "Device" to build and deploy it. The first time, I got prompted to enter a pin after a bit, which I did, and once the deployment was done, the app showed in the "All Apps" section, but once I clicked on it, I got a window that had a white background with a box with an X in the middle of the screen. On top, there is a blue circle with a white loading circle that was loading for forever. I tried rebuilding it multiple times, recreating the Unity project in a new project, and double-checking my Unity build settings, but those were correct. How can I fix this issue? I'm using Unity version 2022.3.20f1. Thank you, Avinash Devineni Edit: Now it started doing the environment scanning visual, but still shows a white box, although there is no blue loading circle anymore. I didn't change anything or redeploy it to the HoloLens 2, so I'm not sure why it started doing something different.

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 1: Gestures not recognized in Unity 2019.4 with MRTK 2.8.3
I own an HoloLens 1 and so far I have developed some AR projects with Unity 2018.4.23f1 using the HoloToolkit (the version available in 2018). Now I want to develop a new project for HoloLens 1 with Unity 2019.440f1 LTS and use MRTK 2.8. I also use Visual Studio 2017. I created a new project and followed Microsoft's instructions on how to install and configure MRTK 2.8.3 (for example, I followed Microsoft manual "Set up a mixed reality project in Unity with the Mixed Reality Toolkit"). I added the MixedRealityToolkit to the new scene I created. For the MRTK Profile configuration, I selected the DefaultHololens1ConfigurationProfile. In the Input section, I activated the InputSystem and selected the DefaultHoloLens1InputSystemProfile. To verify that everything was correctly configured, I added to the scene a 3D cube, and, following Microsoft suggestions, I added the ObjectManipulator and NearInteractionGrabbable components to the cube. When I connect the HoloLens 1 to Unity through Holographic, I correctly see in the Hololens 1 the cube in the scene. Also, if I move the pointer over the cube, it correctly detects the presence of the cube. However, no gestures are recognized and therefore I cannot have any type of interaction with the cube. Even adding a bounding box with handles doesn't change the situation. The handles are recognized (their icons change) by the pointer, but then gestures are not identified and the presence of my hands in the FOV is not detected. I tried creating a new project several times starting from scratch, changing profiles and configurations, but the result is always the same. Is there something I'm doing wrong or missing? thank you for your help
