How can you create AR experiences without internet connectivity?

In order to enjoy AR offline, you have to download ahead the 3D models that you want to use. For example funny hats/glasses/make up are some basic components of mobile AR applications. Once you have the models on device, you just need to activate the detection, localization, tracking algorithms, and you can enjoy the experience, even if the device is in Flight Mode.

Offline AR experiences offer significant benefits, particularly in enhancing user privacy and reliability. For example, in museums or historical sites, AR apps can provide interactive guides without needing an internet connection, ensuring both a smooth experience and the protection of user data. This approach is not only cost-effective but also makes AR more accessible in areas with limited connectivity. One aspect I find particularly helpful is the reduced complexity in deploying AR content, making it more user-friendly and easier to manage. This approach democratizes AR technology, making it feasible for a wider range of applications and users.

Offline AR offers the advantage of providing context to existing artifacts, especially in areas with GPS but no internet access (as with Maps for example). This reduces data requirements by using your camera to make the world in your view meaningful, resulting in more compact offline data storage and footprint. Another major benefit of offline AR is the low latency benefit of whipping out your camera and adding context to anything in front of you instantly. Data connections can be limited in remote areas and especially in places within large building or around anything else that can I interfere with an internet connection.

Augmented reality's one of the major business applications are using it for billboard marketing and outdoor advertising... Mainly in exhibitions or trade fairs, one of the biggest problem, too many network request from same place at same time, effects the internet quality.. So mainly while showing demo of any AR experience using web based AR is bad idea I crowded areas... Choose building pure App based AR, where it is totally non- dependent on internet, and will work seamlessly even crowded places..

We have found it useful to use offline AR with AR-enabled books, and also in fast-paced learning scenarios. In those moments, the short delay in accessing content online could affect the user experience, distracting the users, or even jeopardizing the full experience. Like in videogames, the lag frustrates the gamers, in AR experiences lag could "kill" the UX. This of course requires more space for an app, and more time for the first download. We have delivered apps that if they're offline, they keep working. And if they're online, they check the server for content updates, providing the best of both worlds. Quick access to content, and updates when available.

Bugs are an integral part of any apps. You need to have your app updated atleast once before you could continue using the app. Adding to that, when new modules are added to the game, when the app goes thru a revamp or when user experience is modified it's most likely you will be using the older version of the app. OTA updates will not be possible and the only way to get the latest updates are by an app update. If there was a online feature then you can completely avoid the need update the app, rather send updates on the air without having the need to update the app.

While offline AR offers privacy and accessibility, it faces challenges like limited content and higher app demands. For instance, a city tour AR app might not update points of interest without internet, reducing its relevance over time. Also, storing detailed 3D models locally requires more phone storage and processing power. However, a key benefit is the control over content updates, allowing for curated, high-quality experiences without reliance on unstable internet. This is crucial in places like schools or remote areas, where consistent internet access is a luxury. Despite the challenges, offline AR's controlled environment can still provide valuable, tailored experiences.

Interactivity in AR often depends on real-time data exchanges with servers. In offline scenarios, the lack of constant connectivity can limit the ability to fetch and update interactive elements dynamically, leading to a less dynamic user experience. One Such Major Issue I see is Offline AR applications may face challenges in recognizing complex scenes without access to cloud-based databases or extensive pre-existing maps. This limitation can affect applications like indoor navigation or object recognition in unfamiliar environments.

Es ist definitiv wichtig, die Auswirkungen der Offline-AR auf den verfügbaren Speicherplatz zu berücksichtigen, insbesondere wenn umfangreiche Prozeduren heruntergeladen werden. Die Einschränkungen von IoT- oder Live-Daten können ebenfalls berücksichtigt werden, da diese in einer offline-fähigen Umgebung möglicherweise nicht vollständig verfügbar sind. Die Herausforderungen bei der Größe und Vielfalt der heruntergeladenen Inhalte könnten sich auf die gesamte Funktionalität und Anpassungsfähigkeit der AR-Anwendung auswirken.

An experience is something you share. E.g. a Training - Experience or a simple standard operating procedure. To share an experience, you need to have an internet connection. So instead of investing in an offline modus, invest in an internet connection and secure hosting/data-connection

Most important thing for an offline AR app is the well thought thru user journey which has to be well tested and possibly all potential UX is dealt with before shipping the app. Once the app is out it would be hard to fix it as you would ask them to force update this app. Additing to this we have to keep a tab of the Overall size of the app which is dependant on the specification of 3D assets that are packaged which includes polycounts of 3D , total number of materials within each scene, resolution of texture. Most user interface features are backward compatible. When new os versions are launched we need to make sure the app works well in the new OS too.

In the development of offline AR applications especially in medicine, it's crucial to first define the specific goals and requirements of the medical field. Selecting appropriate AR tracking and rendering methods is essential to provide precise and reliable medical information even without internet access. Additionally, special attention must be given to the design of content and interactions, focusing on user-friendliness and accuracy, to offer effective and intuitive tools to healthcare professionals, even offline.

Designing offline AR requires a smart balance between content richness and device limitations. For example, an offline AR game using a phone's camera for object recognition provides a seamless experience without internet. This approach demands efficient use of storage and processing power. A major benefit is ensuring a consistent user experience, crucial in areas with poor connectivity. The focus is on delivering quality AR interactions within these constraints, making the technology more accessible and reliable.

One Of the way can be, Implement offline scene recognition capabilities. Develop algorithms or use pre-trained models that allow the application to recognize and understand the physical environment without relying on cloud-based databases. Consider leveraging local databases or edge computing for enhanced scene recognition.

For an offline AR app, a meticulously planned and thoroughly tested user journey is crucial. It's vital to anticipate and address all potential user experience (UX) issues prior to release. Since the app operates offline, real-time updates or quick fixes are not feasible. Any necessary modifications after launch would require users to download updates, which might be inconvenient or overlooked. Therefore, ensuring a seamless and intuitive UX from the start is essential to avoid user frustration and to ensure the app's success without relying on post-launch updates.

Design a robust local data storage strategy to handle the storage of pre-loaded content, user preferences, and any dynamically generated data. Optimize data structures and file formats to minimize storage space requirements while ensuring quick retrieval.

Developing offline AR is accessible with platforms like ARKit for iOS and ARCore for Android. These enable robust AR experiences using a device's built-in capabilities. For example, an AR app for indoor navigation can work offline using these tools, guiding users through complex buildings. Cross-platform options like Unity offer versatility for different devices. The standout benefit is the ability to create immersive AR without relying on internet connectivity, crucial for apps used in remote or network-limited areas. This approach democratizes AR, making it more inclusive and practical.

Unity is developer friendly while developing an AR app. Offline AR applications that require maps etc. can be used by initially downloading a particular section of the map. While building the application, ArcGIS or Mapbox can be used to obtain the geographical location. The downloaded map is stored locally and can be used offline later. I tried using this for one of my testbed.

Developing offline AR presents multifaceted challenges. Ensuring reliable tracking and detection in diverse real-world environments without continual internet access is a pivotal hurdle. The intricacies of managing local storage for 3D models and AR data, optimizing performance, and addressing edge cases like low-light scenarios add layers of complexity.

An additional aspect in developing offline AR is integrating advanced AI and machine learning to enhance real-world interaction, even without internet. AI-based image recognition and object tracking can be embedded in offline AR, enabling smoother, smarter user experiences. This is especially beneficial in aerospace, where precision in AR visualization and interaction is critical for aircraft maintenance. AI helps in accurately identifying and tracking objects under challenging conditions, facilitating more efficient and precise offline AR use in the industry.

Testing offline AR is essential to ensure it works reliably in diverse conditions. For example, an AR museum guide app must be tested in various lighting and space settings to guarantee accuracy without internet. Simulating offline modes, like airplane mode, across different devices and environments is crucial. This thorough testing ensures a consistent user experience, regardless of location or device limitations. The most beneficial part of this process is the ability to fine-tune the app based on real-world feedback, ensuring a seamless and engaging experience for all users.

When the experience requires image or floor detection, it's key to have the users using the mobile devices with the right lighting. It has happened that we have delivered AR for museums, and then in the final week, based on special lighting being used over the art pieces, we had to change the image markers to have everything running smoothly. So testing is key, but at the same time, testing with the real environment is mandatory when the app/s are used in places not illuminated as desired.

Testing should be taken care and done in various aspects. Conduct thorough testing of the offline AR system in various scenarios and environments. Optimize for performance, responsiveness, and reliability. Iterate based on user feedback and testing results.

Lo básico es asegurarse que se reproducen las condicciones reales que luego experimentan los usuarios, lo primero es quitarle cualquier tipo de acceso a Internet al teléfono. Si la aplicación requiere de algún tipo de calibración prevía nos tenemos que asegurar que se puede llevar a cabo facilmente sin conexión a Internet. Y como siempre proporcionar mensajes de error claros y opciones de recuperación.

Testing offline augmented reality (AR) applications is a critical step in ensuring a seamless and reliable user experience. Here's a comprehensive guide on how to test offline AR effectively: a. Simulate Offline Conditions: Test the application under simulated offline conditions to identify potential issues and optimize performance. b. User Feedback: Gather feedback from users in areas with varying connectivity to ensure the application's effectiveness in different environments.

Consider carefully the benefits vs cons of offline AR. Most devices that are capable of AR will always have connectivity options available, either via a LAN or 5G/LTE as well. For the vast majority of cases, you'll likely want the experience to be online connected, especially if the goal is to share and create POI's with other users. There are some offline AR benefits, but most likely you'll want online handshakes to gather accurate telemetry data and provide updates as well.

Progressive Downloads: Partial Asset Loading: Implement a progressive download strategy where essential components of the AR experience are loaded first. This allows users to start the experience with basic functionalities even before the full content is available. Caching Mechanisms: Implement caching mechanisms within the AR application to store previously accessed data. This helps in reusing content that has already been downloaded, minimizing the need for constant internet access. Asset Bundling: Package necessary AR assets into bundles that users can download in advance. These bundles can include everything needed for a specific AR scenario and can be accessed offline.

Para criar uma experiência de realidade aumentada de qualidade, é crucial considerar diversos elementos essenciais. Estes incluem: - Objetivo da ativação - Público-Alvo - Storytelling - Tecnologia de Realidade Aumentada - Local e Método de Desenvolvimento - Planejamento da Experiência do Usuário - Atualizações Futuras - Especificações de Recursos Visuais - Compatibilidade com Dispositivos - Compatibilidade com Sistemas Operacionais - Segurança e Armazenamento de Dados

We built offline app for an Event company who were showcasing their products in an expo. We considered offline because the foot traffic was expected to be high and client does not want to miss the opportunity to showcase their products.

El uso de las aplicaciones de realidad aumentada sin acceso a la red serán bastante reducido en comparación con el resto de aplicaciones (conectadas y mixtas) que ofrezcan servicios conectados como a día de hoy podemos comprobar con aplicaciones 2D. Sin embargo, gracias a los procesadores y componentes cada vez más pequeños, potentes y eficientes, el usuario podrá acceder a una enorme cantidad de funcionalidades que ofrecerá el propio dispositivo: escaneo de espacios físicos, detección de movimientos y gestos, análisis de voz y lenguaje, escaneo de pupilas... Todas estas funcionalidades ofrecerán a los desarrolladores la capacidad de crear apps útiles para diferentes ámbitos (salud, ocio, aprendizaje) sin la necesidad de acceso a la red.
