今天我们欣喜揭晓获奖项目：

冠军：Gemma Vision
这款为视障群体设计的AI助手，其开发者的盲人兄弟在功能优化中发挥了关键作用。考虑到持杖行走时操作手机不便，系统通过固定在胸前的手机摄像头采集视觉信息，用户可通过8BitDo微型控制器或语音指令触发功能，无需触碰屏幕菜单。
该项目同时荣获Google AI Edge特别技术奖，通过MediaPipe LLM推理API部署Gemma 3n，并运用flutter_gemma包的流式响应功能实现流畅体验。

亚军：Vite Vere离线版
该应用致力于提升认知障碍者的自主能力。原基于Gemma API开发的项目通过Gemma 3n实现离线化，将图像转化为简明指令后调用本地语音引擎播报，帮助用户完成日常任务。

季军：3VA
患有脑瘫的平面设计师伊娃数十年来仅能表达"现在要吃饭"等简单需求。该项目对Gemma 3n进行微调，将象形符号转化为丰富表达。团队使用苹果MLX框架本地训练模型，为个性化增强替代沟通技术提供了高性价比方案。

第四名：安保人员的第六感
区别于传统动态监测系统，该项目通过Gemma 3n实现人类级场景理解，能区分普通事件与真实威胁。系统集成轻量级YOLO-NAS模型进行初筛，再由Gemma 3n处理数据，可实时解析高达360帧/秒的16路视频流。

Unsloth奖：梦想助手
针对语音助手对言语障碍者识别率低的问题，该项目采用高效微调库Unsloth，基于个人录音训练Gemma 3n，打造出能理解用户独特发音模式的定制化AI助手。

Ollama奖：LENTERA
通过将平价硬件改造为离线微服务器，该项目为网络薄弱地区带来AI服务。Lentera设备创建本地WiFi热点，用户可通过Ollama平台连接运行Gemma 3n的教育枢纽。

LeRobot奖：图神经网络成本学习与Gemma 3n感知系统
为解决机器人探索中感知耗时过长的问题，团队在Hugging Face机器人框架LeRobot上构建创新"扫描优先"流程，由Gemma 3n制定计划，归纳式图矩阵补全模型预测延迟，验证了边缘端具身AI的可行性。

NVIDIA Jetson奖：我的（Jetson版）Gemma
该项目通过智能CPU-GPU混合处理策略，在Jetson Orin设备上部署情境感知语音交互界面，展现了AI突破屏幕限制、赋能现实场景的潜力。

从无障碍支持到应急响应，这些项目彰显了Gemma 3n的无限可能。更多优秀作品值得关注，欢迎通过@googleaidevs账号持续了解开发者故事，我们将进行为期一个月的专题报道。

These developers are changing lives with Gemma 3n
When Gemma 3n was released, we hoped developers would use its on-device, multimodal capabilities to make a difference in people’s lives. With more than 600 projects submitted to the Gemma 3n Impact Challenge on Kaggle, the community delivered on that promise.
Today, we’re excited to introduce the winners:
First Place: Gemma Vision
Gemma Vision is an AI assistant designed for visually impaired people. The developer’s brother, who is blind, played a vital role in ensuring features were genuinely helpful for the blind community.
Because holding a phone can be impractical while using a cane, the system was designed to process visuals from a phone camera strapped to the user’s chest. Functions can be triggered using a 8BitDo Micro controller or voice commands, allowing users to perform actions without navigating touchscreen menus.
This project also won the Special Technology Prize for Google AI Edge, a platform for deploying models on-device. It deployed Gemma 3n using the MediaPipe LLM Inference API and leveraged features like streamed responses in the flutter_gemma package to make the experience fluid.
Second Place: Vite Vere Offline
Vite Vere helps foster autonomy for people with cognitive disabilities. Originally developed using the Gemini API, this project leveraged Gemma 3n to make the digital companion work offline. By transforming images to simple instructions that can then be read aloud using the local device’s text-to-speech engine, the app enables users to navigate daily tasks.
Third Place: 3VA
For decades, Eva, a brilliant graphic designer with cerebral palsy, was limited to simple commands like “want food now.” This project fine-tuned Gemma 3n to translate pictograms into rich expressions that better reflect Eva’s voice. The team trained the model locally using Apple’s MLX framework, demonstrating a cost-effective way to develop personalized Augmentative and Alternative Communication (AAC) technology.
Fourth Place: Sixth Sense for Security Guards
Unlike traditional video monitoring systems that just detect motion, this project used Gemma 3n to provide human-level context and distinguish benign events from genuine threats. By integrating a lightweight YOLO-NAS model to detect initial movement and send it to Gemma 3n for processing, the system can handle high-bandwidth video feeds (up to 360fps and 16 cameras) in real time.
The Unsloth Prize: Dream Assistant
Voice assistants frequently fail users with speech impairments. This project used Unsloth, a library for efficient fine-tuning, to train Gemma 3n on an individual’s audio recordings. The result is a custom AI assistant that understands the user’s unique speech patterns and enables voice control over device functions.
The Ollama Prize: LENTERA
This project demonstrates how to bring AI to disconnected regions by transforming affordable hardware into offline microservers. Lentera broadcasts a local WiFi hotspot, allowing users to connect their devices to an educational hub running Gemma 3n via Ollama, a platform for local model deployment.
The LeRobot Prize: Graph-based Cost Learning and Gemma 3n for Sensing
Robotic exploration is often bottlenecked by the time spent sensing rather than moving. To solve this, the team built a novel “scanning-time-first” pipeline on top of LeRobot, a robotics framework developed by Hugging Face. This project used Gemma 3n to create plans while an inductive graph-based matrix completion (IGMC) model predicted latencies, demonstrating the viability of embodied AI at the edge.
The NVIDIA Jetson Prize: My (Jetson) Gemma
Integrating AI into our physical environment requires systems that are both responsive and energy-efficient. This project used a smart CPU-GPU hybrid processing strategy to deploy a context-aware voice interface on an NVIDIA Jetson Orin, demonstrating how helpful AI can move beyond screens to assist users in the real world.
From accessibility to crisis response, these projects show what's possible with Gemma 3n. Many others deserve recognition, so join us as we highlight a developer story every day on @googleaidevs over the coming month.
