Have you thought about viewing your #digital #3D #archaeology models in-situ in a trench at your site? Read our article on the use of #MixedReality and #AugmentedReality (#MR/#AR) in archaeological #fieldwork in the Journal of Computer Applications in Archaeology (#JCAA)! Our experiments utilized three devices: the Vuzix Blade 2 AR smart glasses, the Microsoft #HoloLens2, and the Meta #QuestPro MR headsets. These experiments aimed to enhance fieldwork efficiency and accuracy through hands-free data collection, stratigraphic comparisons using 3D models, depth-guidance systems for excavation, and virtual pottery reconstruction. Our findings highlight the significant potential of MR/AR technologies to transform archaeological practices. Our vision for the future demonstrates that these tools will, one day, provide archaeologists with enhanced vision and data interaction capabilities, ultimately advancing the field.
In less than 3 months, our article already has over 3000 views, so we thank you for your interest in exploring the future of digital archaeology with us!

您是否想過在考古現場的壕溝中查看數碼3D考古模型？請閱讀我們在《考古學電腦應用期刊》(#JCAA) 中關於在考古現場中使用混合現實和擴增實境 (#MR/#AR) 的文章！我們的實驗使用了三種裝置：Vuzix Blade 2 AR 智慧眼鏡、Microsoft #HoloLens2 和 @Meta #QuestPro MR 耳機。這些實驗旨在透過免持的資料收集、使用 3D 模型進行地層比較、挖掘深度引導系統和虛擬陶器重建，來提高考古現場的工作效率和準確性。我們的研究結果凸顯了 MR/AR 技術在改變考古實踐方面的巨大潛力。我們對未來的願景是，有一天，這些工具將為考古學家提供增強的視覺和數據互動能力，最終推動該領域的發展。 在不到3個月的時間裡，我們的文章已經有超過3000次瀏覽，感謝您有興趣與我們一起探索數碼考古的未來！

Lilbits: Pixel 9a pictures and Apple’s smart display plans leaked, Thunderbird for Android Beta is here, and Adobe adds AI to its entry-level photo and video apps

Google’s next mid-range phone could look a little different. Adobe is bringing AI features to its entry-level versions of Photoshop and Premiere. Apple may be planning to launch two smart displays. And the first public beta of the new Thunderbird email app for Android is here… although it’s really just a Thunderbird-branded version of an existing email client.

Here’s a roundup of recent […]

Two weeks ago I released my based app Walk the World for , a week later the exact same app for . I promised to blog how I so easily and quickly got that done, and here it is: my 'recipe' for getting MRTK3-based HoloLens 2 apps to run on Magic Leap 2. localjoost.github.io/Making-an

DotNetByExample - The Next Generation · Making an MRTK3 based HoloLens 2 app run on Magic Leap 2This is a bit of an unusual post, as it does not have a project attached to it. Instead, it’s more like a recipe that I followed to get my app “Walk the World”, originally developed for HoloLens 2, to run on Magic Leap 2. Or actually, how I did it after retracing all my steps, cutting out all the useless detours, pitfalls, and dead ends I encountered trying it the first time.

Sometimes you need to know whether or not the user is now actually wearing the device while your app is running. I wrote a little Service to make that easily detectable

localjoost.github.io/Detecting

DotNetByExample - The Next Generation · Detecting user presence using MRTK3 gaze tracking stateSometimes it’s necessary to know whether or not the user is actually wearing the headset while running your app. For instance, this might be because the user is doing an important task that may not be stopped until completed, or because you want to pause critical, performance-heavy, or battery-draining processes on the device when the user takes it off for a few minutes. I have found MRTK3 gaze tracking state to be a reliable way to detect user presence, and wrote a little ServiceFramework Service to utilize that.

has a subsystem implementation for speech commands that is supported by . supports voice commands as well, if only someone had taken the trouble of making a KeywordRecognitionSubsystem implementation of it, it would have had MRTK3 support for speech commands as well.

Well, guess what - someone just did. Me. So now you can have voice commands on *both* devices using the same API, and you only need to flip a checkbox in the MRTK3 settings.

DotNetByExample - The Next Generation · An MRTK3 KeywordRecognitionSubsystem for Magic Leap 2As I have shown already, MRTK3 is very versatile and very well suited for cross-platform development. The architecture is extensible by the usage of Unity subsystems. At Magic Leap, they have used that to implement a version of the Hands subsystem - that allows hand tracking to work - and you can use that by simply selecting a different implementation of the subsystem in the Android MRTK3 profile:

When debugging problems after-the-fact, you can always use UnityPlayer.log. On , that is. On other devices - for instance - that's not available. So I wrote a little service to dump logfiles in a file for an app running on a device. While I was at it, I included filtering on keywords and log type as well.

DotNetByExample - The Next Generation · A cross-platform Service Framework service to write Unity log messages into files on-deviceHoloLens applications conveniently dump all the Unity log messages in a text file - including all run time errors. This file can be very useful for tracking down weird occasional errors that only happen at run time. Getting to the file from HoloLens is a bit cumbersome, you have to go via the device portal and you really have to know where to look, it is always called UnityPlayer.log and at least you can get to it.

For my second blogpost of the day ;) one of my more infamous and far-fetched experiments encompasses the combination of combined with a Spatial Map to recognize and locate objects in 3D space, using a model. This worked pretty well on . I got it to work on as well, but it was quite a rocky road. The to the rescue :). Explanation, sample and full code at: localjoost.github.io/Running-a

DotNetByExample - The Next Generation · Running a YoloV8 model on a Magic Leap 2 to recognize objects in 3D spaceAfter I successfully got to run YoloV8 models on HoloLens 2 to recognize the model aircraft I made as a teenager and locate them in space - using the Unity Barracuda inference engine to process the model - I thought it would be fun to try this on the Magic Leap 2 as well. The short version of this experiment is - it worked, as this 4x sped up video shows:

I wanted to see if I could run one of my more far-fetched samples on . Step one was getting a Spatial Map. It was dead easy on HoloLens 2, but less so on Magic Leap 2. I managed to make it work, but there were more challenges than I had anticipated. I blogged my findings to help others avoid the same pitfalls as me.

DotNetByExample - The Next Generation · Using a Spatial Mesh with MRTK3 on Magic Leap 2After successfully porting the MRTK3 version of HoloATC to Magic Leap 2, I wanted to try some other experiments on it as well. For one of those experiments, I needed to use the Spatial Map. How hard could that be? I just added an ARMeshManager to the XR MRTK Rig like I do for HoloLens, as per my own blog post, and…

I just blogged: " , hover and select events - and how to use them" localjoost.github.io/MRTK3-Sta

There's a lot of events on StatefulInteractable, and it might not be abundantly clear how to use them and why. Therefore, I decided to make a simple sample that shows you which event is triggered by what, and allows you to experiment with those events

DotNetByExample - The Next GenerationMRTK3 StatefulInteractable gaze, hover and select events - and how to use themWhen my colleague Sophie asked me if I had a sample for something I had written before, but then for MRTK3, I had to admit that I did not. So I set out to create that sample for MRTK3 - after all, I had already used gaze interaction with MRTK3 in my cross-platform HoloATC app. I ended up exploring quite a few possibilities of the MRTK3 StatefulInteractable component and found out that there are a lot more events that can be dealt with.

Some time ago Unity announced "Unity XR Hands". I decided to check out how this works on the platforms I develop on. Turns out you need to jump trough some hoops. I documented what hoops and how to jump them and

localjoost.github.io/Getting-U

DotNetByExample - The Next GenerationGetting Unity XR hands to work on HoloLens and Quest in a bare bones projectRecently I saw someone (I think on LinkedIn) post a screenshot about Unity XR Hands - this basically claims hand tracking via a standard Unity API, using a plugin architecture. There is very little information in Unity documentation about how to get it to work (*cough* nothing new there *cough*), and it’s all in preview. I wondered how hard it would be to set it up in a bare bones project (so without MRTK or any other toolkit) and having it to work on HoloLens 2 and Quest. Turns out, this is quite doable, although for Quest (Android) there’s a strange hoop you have to jump trough. But it works!
