Smart glasses have returned to the technological spotlight thanks to Google's renewed commitment, which has unveiled a revolutionary prototype known as Google Martha. After years of discretion and the memory of the first Google Glass, the technology giant now seeks to lead the augmented reality market and expand its artificial intelligence solutions, integrating Android XR and Gemini in a new format aimed at both daily utility as the fashion.
In this article, we'll tell you in detail everything we know so far about Google Martha, its technology, features, Google's strategy and collaborations, the state of development, and how it compares to other current offerings. If you're looking for a complete and up-to-date overview of the future of Google smart glasses, here it all is gathered and clearly explained, also integrating the market context and the challenges that Google itself acknowledges.
The return of Google's smart glasses: context and news
Google has revived interest in smart glasses by presenting the Google Martha prototype as the basis for its new generation of Android XR devices. This is a project that incorporates the experience and lessons learned from the unremarkable launch of Google Glass, with the firm intention of overcoming past mistakes and launching a new product. Useful, aesthetic and loaded with smart functions really useful in everyday life.
The development of Google Martha comes at a time when the AI-powered smart glasses market is experiencing rapid growth, with a significant increase in shipments and a strong presence from manufacturers like Meta, Xiaomi, and XREAL. In this context, Google aims to occupy a central position with a product that combines open ecosystem, Multimodal AI and a partner network covering everything from hardware to fashion design.
This prototype incorporates the Android XR operating system, developed specifically for extended reality (XR) devices such as glasses and viewers, and works hand in hand with Gemini, Google's generative AI. Android XR introduces a new software experience designed to be a constant companion, not a nuisance.redesigning the interface and animations so that the information appears subtly and unobtrusively in the user's field of vision.
Everything suggests that what is currently just a prototype will lay the groundwork for future commercial models, as has happened in other technology sectors. Behind the scenes, names like Project Moohan (Samsung's XR headset) or Project Aura (glasses with XREAL) are part of the same Android XR ecosystem in which Google Martha acts as a benchmark for the format. Lightweight glasses for everyday use.
Why is Google called Martha?
The term Google Martha is the internal codename (or prototype name) that Google and its engineers have assigned to this device during its development. The name came to light after an investigation by specialized media and the leak of an image of the glasses' companion app, shared by the developer. Sayed Ali Alkamel, in which the name of the connected device was clearly visible.
These types of code names are very common in the sector during the new product development stage and do not always reach the end consumer, but they help to identify internal advances and differentiate the various projects. In the filtered companion app, menus such as Notifications, Settings, the option Record your view and sections for post comments y report problems, all of them explicitly associated with Google Martha as the name of the Android XR smart glasses prototype.
Specialized media outlets such as Android Authority have confirmed that Google Martha is the name Google uses to refer to the prototype of smart glasses with Android XR and Gemini., differentiating it from other XR projects such as the bulkier viewers or the glasses developed together with other partners.
Google Technology Martha: Android XR and Gemini
The Google Martha glasses are based on Android XR, an operating system created from scratch by Google adapted to the needs of extended reality. Although it inherits some of the flexibility and ecosystem of Android on mobile, Android XR redesigns the interface to prioritize the transparency, high contrast and subtlety of the elementsso that the information does not obscure the physical environment but rather complements it.
In the experience shown by Google, the information is presented mostly in the bottom of screen from the glasses, with always transparent backgrounds. When interacting with the interface, the environment blend lightly to allow focusing on digital elements, but remain recognizable so the user maintains spatial reference. Additionally, the following are used smooth animations and transition times of up to two seconds so that the gaze can move from the physical world to digital content smoothly.
The other big key is Gemini, Google's generative AI deeply integrated into the system. Thanks to Gemini, the user can interact with the glasses using natural language, both by voice and, in part, through the visual content captured by the camera. The AI ​​is capable of processing information. multimodal: combines voice, camera images e contextual information (location, recent interaction history, objects in the environment) to provide much richer answers.
This translates into functions such as real time translation, recognition of objects and places, encyclopedic queries based on what you are viewing, step-by-step help for using physical devices (for example, a coffee machine) or assisted navigation with superimposed instructions. In the practical demonstrations, a long press on the touch panel of the temple was enough to activate Gemini, which responded with both voice and text projected onto the lens.
Google insists that these glasses are not intended to completely replace mobile phones immediately, but rather to become an ever-present assistant who shares your perspectiveWith Gemini in the glasses, the company wants the user to be able to stay connected with the world around them, without needing to look down at a flat screen every few seconds.
What features and options do they offer?
Google Martha is conceived as a functional base from which Google is experimenting with different everyday use cases. Many of these features are visible in the leaked companion app, and others have been shown in closed demos or on stage. Among the most notable options are:
- Real-time notifications: Receive messages, alerts, or events directly in your field of vision, without taking your phone out of your pocket. Android XR prioritizes displaying brief information y easy to discard, avoiding overwhelming the user's view with constant banners as on mobile.
- Contextual AI Assistant (Gemini): It allows you to ask all kinds of questions, interact via voice, and obtain useful information based on your immediate surroundings. Gemini understands what you see through the camera, so you can ask for a monument, an checks or product simply by looking at it.
- Configuration management and adjustment: From the companion app, you can modify settings related to the privacy, the visual experience, the intensity of notifications, the camera's behavior or Gemini's level of background involvement.
- Recording user view: There is a specific function to capture video of what the user sees, recording both the exterior scene and the glasses interface. This is especially useful for document processes, create content or share feedback with the development team.
- Feedback and troubleshooting: Built-in options for submitting suggestions, reporting bugs, and contributing to device improvement during the development phase. Google uses these metrics to adjust the interface design, the user experience and function priorities.
- Recognition and simultaneous translation: Gemini allows you to identify objects in real time, translate texts and conversations from other languages, instantly eliminating language barriers. The translation can be displayed as superimposed subtitles either through the lens or only by audio, depending on the usage mode.
- Assisted navigation and maps: In combination with Android XR, the glasses can display turn by turn directionsschematic maps in your field of vision and even a compass which indicates the direction you are looking, making it easier to orient yourself without looking at your phone.
- Quick multimedia capture: In addition to video, the glasses allow you to take Hands-free photographyThis is ideal in environments where you don't want to or can't take out your phone (for example, while cooking or exercising).
Tests conducted by journalists and content creators who had access to the prototypes highlighted that the projected textual information can still be somewhat difficult to understand. uncomfortable to read for extended periods, which indicates that the product is in a relatively early stage of development. However, Google considers these tests a key source for adjusting fonts, sizes, and content density.
Design details: a screen on the right lens
The Google Martha prototype features a display only on the right lens, a decision that differentiates it from other devices that use dual screens or rely solely on audio. This monocular design allows for a lighter and more natural experience, keeping the other eye free of digital elements, although it has the peculiarity that if you close your right eye, you lose digital vision completely.
This approach is consistent with other smart glasses on the market that opt ​​for a Monocular HUD to reduce weight, complexity and energy consumption, although Google has already shown that it is also working with binocular designs (one screen per eye) in other prototypes. These dual-lens models allow you to enjoy a wider virtual field of view and more immersive augmented reality experiences, for example for video calls or Google Meet meetings projected in the air.
Google has clarified that the use of the HUD (Head-Up Display) will be optional in future commercial models. Thus, there will be glasses focused solely on voice or audio interaction—lighter and more discreet—and others, more advanced, that will include a head-up display (HUD) to show superimposed information in real time. This modularity extends to the Android XR ecosystem itself, where most experiences are being designed to work both with the screen and in audio-only mode.
In the Android XR demo, Google showed how the HUD can be used for functions such as Google Maps o Google Meetteaching everything from simple route directions to a top-down map with a compass that indicates where you're facing. It was also demonstrated how, by taking a photo and asking Gemini to edit it with generative models, the user can see the preview of the result directly onto the lens, without using a mobile phone.
Furthermore, these glasses feature a design visually similar to traditional sunglasses or prescription glasses, something that has become standard since the success of the Ray-Ban Meta. The intention is that, once they reach the public, the user won't feel like they're wearing an obviously futuristic device, but rather a fashion accessory that goes unnoticed.
Key collaborations: fashion, design and technology alliances
One of Google's most important goals is to avoid the aesthetic and usability failure of the previous Google Glass, now collaborating with leading fashion and design brands such as Gentle Monster and Warby Parker. The integration of fashion and technology aims to transform these glasses from a mere eye-catching device into a desired accessory that fits any lifestyle.
Warby Parker brings his experience to stylish frames for everyday usewhile Gentle Monster is aimed at an audience that particularly values ​​the luxury design and the most cutting-edge trends. Google has announced an investment of up to 150 million in their collaboration with Warby Parker, divided between development and marketing costs of smart glasses and an equity stake subject to business objectives.
The collaboration with Samsung is at the core of the Android XR platform. Both companies are working on a reference hardware and software base (visible in projects like Galaxy XR or Project Moohan) that will allow different manufacturers to launch their own compatible glasses and viewers, creating an ecosystem of various devices that share the same applications and services. The goal is to replicate the strategy that made Android the dominant mobile operating system: a open platform that accommodates multiple partners.
Along with these names, other key players come into play: XREAL as a long-term partner for clear glasses in Project Aura, Kering Eyewear as a gateway to more fashion brands, Qualcomm handling the chips optimized for XR and Sony supplying advanced sensors. Even Magic LeapNow under Google's umbrella, it could play a role in developing optical and tracking technologies for future generations of glasses.
Agreements with companies such as Kering Eyewear are mentioned.This demonstrates the intention to reach a wide audience with glasses that people would actually want to wear every day. The traditional design, similar to that of conventional sunglasses, will set them apart from the bulky and inconspicuous devices of past generations. Furthermore, the diverse partnerships will allow them to cover a wide range of needs. different price ranges y user segments, from more basic models focused on audio to premium glasses with advanced HUD.
Comparison with the competition: Meta, Apple, XREAL and other manufacturers
The smart glasses market is in full swing, and Google isn't the only major player. The Ray-Ban Meta sunglasses, developed by Meta, have been very well received thanks to their lightweight design, fashionable style, and smart features such as photo and video capture and voice assistant access. Meta is already working on sunglasses with a head-up display (HUD) and gesture control via sEMG neural wristbands, as well as collaborations with sports brands like Oakley.
Meanwhile, Chinese manufacturers such as Xiaomi, TCL-RayNeo, Thunderobot or Kopin They are making a strong entry into the AI ​​glasses segment, quickly becoming one of the best-selling models. XREAL, for its part, has established itself as one of the most important players in transparent AR glasses connected to other devices, and is now collaborating closely with Google through Project Aura on Android XR.
Apple is also developing its own smart glasses, with rumors about a phased rollout into the consumer market. Their strategy, as usual, is more closed and based on a proprietary ecosystem, which contrasts with the open approach of Android XR. Meanwhile, Snap is preparing its own augmented reality glasses for consumers, adding more competition to the sector.
The key difference between Meta's approach and Google's is the distinction between a closed ecosystem and one openWhile Ray-Ban Meta and its successors operate on a platform entirely controlled by Meta, Google is betting that the apps from the Galaxy XR and Android XR universe can run on any certified device, multiplying the number of hardware partners and customization possibilities.
The main difference in Google's proposal is the deep integration with Gemini and the development of Android XR as an open operating system, which could facilitate the proliferation of models and functionalities for different users. This combination seeks to replicate the success of Android in mobile phones: a common base on which manufacturers, developers and fashion brands can build their own visions of smart glasses.
User experience and practical usability
One of the historical challenges of smart glasses has been the user experience, design, and actual utility in everyday life. Google Martha aims to solve these problems by opting for an aesthetic similar to traditional glasses, but with profoundly transformative functionality: receiving notifications, consulting AI information, recording what you see, translating conversations in real time, navigating the city and much more, all without needing to take your eyes off your phone.
The Android XR user interface has been designed with the glasses in mind. discreet companionTherefore, visual elements are preferably placed in the lower part of the field of vision, with constant transparency, and animations are designed to give the eye time to adapt. Google has explained that the glasses should not become a source of distractionbut on a channel to show the fair amount of information in the right moment.
The system relies on voice and gesture interaction, with a clear, accessible, and customizable interface, always taking into account privacy and control of personal data. The user can decide what type of notifications they want to see, what data is stored, how the camera is used, and when the assistant is listening. For example, in the prototypes tested, a touch button on the temple to activate or pause Gemini, preventing the AI ​​from constantly listening.
The user experience also includes visual privacy indicatorsThese include LEDs that light up when the camera is recording, alerting people nearby that they may be being filmed. This type of signaling addresses the criticism Google Glass received and aims to build trust with both users and those around them.
An important detail is the focus on privacy and data protection, announced as a pillar in the strategy of the new Google glasses. In regions particularly sensitive to surveillance, such as Europe, the management of cameras and microphones on such personal devices is a critical factor. Google states that it is working on policies of transparency, user data control, and local processing whenever possible, supported by optimized versions of the Gemini models designed to run efficiently on mobile devices.
Development phase, prototypes and roadmap
Currently, Google Martha is a working prototype not intended for public sale, although demonstrations have been given at events such as Google I/O and TED2025. The units shown have features still in the adjustment phase, such as screen quality, comfort in long sessions or software stability, something that Google has openly acknowledged when talking about a still early development cycle.
There is no definitive release date, but It is estimated that the first commercial devices, developed in collaboration with Samsung, could arrive in 2026.Meanwhile, projects from partners and competitors are progressing in parallel and could be released sooner, so Google remains cautious and avoids promising specific timelines.
This open development phase allows Google to test key features, refine the design and user experience, and integrate lessons learned from feedback from developers who have already tested the prototypes. Some testers point out that, while there is room for improvement in HUD comfort and text readability, the integration of Gemini and the ability to see what you see It opens up a range of use cases that did not exist in the previous generation of smart glasses.
Beyond hardware, the roadmap includes continuing to expand the Android XR partner network, strengthening cross-device compatibility, and creating a XR application and experience base that makes sense both on a mixed reality headset and on lightweight glasses. Google wants to avoid users having to learn different interfaces every time they switch devices.
Impact on the user and the future of digital interaction
Google's commitment to smart glasses goes beyond launching a trendy gadget: it seeks to transform the relationship between people and digital information. If the integration of AI, attractive design, and usability live up to expectations, we could be facing a paradigm shift in which the mobile phone ceases to be the central device of daily life, giving way to lightweight glasses that we wear most of the time.
Google's vision aligns with predictions from various industry leaders; Figures like Mark Zuckerberg have even said that by 2030 we will barely take our mobile phones out of our pockets Because we'll do everything through the glasses and voice. Gemini, functioning as a omnipresent assistant that sees, hears and understands what we do, could simplify tasks such as translation, note-taking, process documentation, urban navigation or consulting contextual information.
However, this scenario also presents significant challenges: battery durationwhich should be sufficient to withstand long days; the processing power necessary to run AI models in real time without overheating; the quality of the screens so that they are legible even in broad daylight; and, above all, the data privacy, a particularly sensitive issue in regions with strict regulations.
Price will be another decisive factor. Google Glass failed, largely due to its very high cost relative to its perceived usefulness. In contrast, Ray-Ban Meta glasses have demonstrated that there is strong demand in the price range of half price If the product combines an attractive design with clear and useful features, Android XR will need to be competitive in this area to gain a large enough user base to attract developers and brands.
If Google and its partners are able to balance utility, comfort, privacy, price y aesthetic appealGoogle Martha and the glasses that emerge from this prototype could become the gateway to a new way of interacting with technology, more natural, contextual and less dependent on traditional screens. Share the information and more people will know about Google MarthaThe greater the public interest, the faster these types of devices and their application ecosystem will evolve.
