Le petit denier, fun et plein de rebonds! 👩🔬 Our spatial computing experiments continue… We believe successful spatial experiences should always put fun at the forefront. So we put this principle to the test, exploring how spatial computing can be used to create a fun and reactive play space. Reality Smashers is a mixed reality game prototype that playfully destroys the boundaries of physical space. Players shoot balls to break through their walls and uncover virtual layers mapped to their real world environment.

Exciting news! Our latest blog post delves into the world of image processing and vectorization storage, specifically focusing on electronic maps for underground parking garages. The study details the utilization of image processing, vectorization, and rasterization storage to achieve a more precise analysis of images. The post also introduces a method for the vectorization classification storage of indoor two-dimensional map raster data, demonstrating its potential for efficient storage and rapid querying of indoor maps.

So without phrasing the post in a LinkedIn "professional" standard template with much exaggeration and unrealistic stuff, Eleni Stroulia and I are simply cool, competent people who have cool research ongoing, and our paper titled "CampusGo: Augmented Reality Indoor-Outdoor Navigation through a Campus Digital Twin" was accepted at 34th International Conference on Collaborative Advances in Software and COmputiNg (IEEE CASCON). The paper primarily establishes a standardized method for indoor path-planning. It also presents an architecture that unifies outdoor and indoor path-planning. And it highlights our even cooler ongoing work on an advanced AI indoor localizer. See you in Toronto! Acknowledgment: Christoph Sydora, Kalvin Eng. #cascon2024

«16 The City of Tomorrow: Sensors, Networks, Hackers, and the Future of Urban Life By #CarloRatti and Matthew Claudel Since cities emerged ten thousand years ago, they have become one of the most impressive artifacts of humanity. But their evolution has been anything but linear—cities have gone through moments of radical change, turning points that redefine their very essence. In this book, a renowned architect and urban planner who studies the intersection of cities and technology argues that we are in such a moment. The authors explain some of the forces behind urban change and offer new visions of the many»

Dspace 8 will be a great improvement from the community effort that started with DSpace 7. It will not be a huge upgrade like DSpace 7 was, but it will introduce many great features such as the COAR Notify ones: Why COAR Notify? Remember when the OAI-PMH protocol was an emerging idea? The DSpace community embraced the challenge looking at the future of the platform. The OAI-PMH protocol faced skepticism, but today, it’s a cornerstone of DSpace and the scholarly ecosystem as a whole. Well, COAR Notify will follow a similar trajectory. Let’s dive into the details: What’s COAR Notify All About? COAR Notify is all about linked data notifications—a fancy term for seamless communication between repositories and external services. Features That’ll Make Your Repository jump in the future Embedded Inbox Magic: DSpace 8 will display an embedded inbox that can receive notifications.   Automatic Discovery: COAR Notify will be generating LDN (Linked Data Notification) messages about DSpace items. It’s like Cupid with a PhD in metadata. 💘  Queue It Up: Incoming and outgoing messages will queue up for asynchronous processing. Why? Because even notifications deserve a little patience. Why Should You Care? These features aren’t just features to make DSpace look famcy, they’re the future of repositories. Sure, not every institution will jump on the COAR Notify bandwagon right away, but that’s okay. DSpace with these features is ensuring we don’t get stuck in the repository Stone Age. 🦕 🔍 Long-Term Vision: The DSpace community isn’t just thinking about tomorrow; we’re working for the next decade. DSpace 8 with COAR-Notify is our ticket to embrace the future, and not fear it. Embrace the change and let’s move forward together #DSpace8 #COARNotify #FutureReady #Openness #Innovation

This week is The Institute of Navigation GNSS+ 2024! This year, on behalf of David Contreras Franco, I am presenting our work "Reinforcement Learning Framework for Robust Navigation in GNSS Receivers". Come check it out!   The presentation and paper introduce the reinforcement learning bandwidth adaptive control (RLBAC), a novel model-constrained, data-driven architecture designed to adjust the response time of a GNSS receiver's tracking stage. The RLBAC extends the loop-bandwidth control architecture (LBCA), which adjusts the response time by performing a weighted difference between noise and dynamics estimates from the discriminator's output. Unlike the LBCA, where the weights are manually tuned, RLBAC employs a reinforcement learning framework to optimize these weights automatically. The RLBAC has been implemented and tested in the GOOSE© GNSS receiver, developed by Fraunhofer IIS and marketed through TeleOrbit GmbH. To the authors' knowledge, this is the first successful application of reinforcement learning implemented in the tracking stage of a GNSS receiver. Thanks to the coauthors Georgios (Giorgos) Kontes, Tobias Feigl, Christopher Mutschler and Alexander Rügamer for their valuable contributions.   The presentation is in all-source intelligent PNT methods, Session E4, on Thursday, 19 September, at the Hilton Baltimore Inner Harbor in Baltimore, Maryland. The ION GNSS+ 2024 meeting is the world’s largest technical meeting and showcase for GNSS technology, products, and services. A commercial exhibit and pre-conference tutorials are held in conjunction with the conference.
