What is Google’s ‘Circle to Search’
Google's 'Circle to Search' is a new AI-powered search feature that allows users to initiate searches directly from their Android smartphone screens without leaving the current app. Here are the key details about this feature:
It enables users to search for information about any object or item on their screen simply by circling, highlighting, or tapping on it using gestures.
Once an item is circled, Circle to Search leverages computer vision and AI to identify and understand the selected object.
It then provides relevant information, details, and options to explore similar products from various online retailers, all within the same app without switching contexts.
For example, if you circle a product in a video, Circle to Search will surface information about that product, pricing, reviews, and where to buy it online.
The feature utilizes Google's latest AI capabilities, including computer vision models for object detection and natural language processing models like the large language model Gemini for understanding user intent.
Circle to Search aims to make visual search more intuitive and seamless by allowing users to express their interests naturally through gestures on their smartphone screens.
The AI/ML Technology Stack Behind Google’s Circle to Search Feature
At the core of Circle to Search lies a sophisticated technology stack that combines cutting-edge computer vision, natural language processing (NLP), knowledge retrieval, on-device processing, and cloud integration. Google's proprietary large language model, Gemini, plays a pivotal role in comprehending users' visual search queries and generating relevant responses. Complementing Gemini are advanced computer vision models and object detection algorithms that accurately identify and understand the objects or elements users circle or highlight on their screens. To ensure a seamless experience, Circle to Search leverages multimodal learning approaches, allowing AI models to understand and reason across different data modalities, such as images and text. While much of the initial processing happens on the user's device for low latency and privacy, the feature also integrates with Google's cloud infrastructure for more complex queries and access to the company's vast knowledge base.
Gemini LLM: Google's proprietary Gemini large language model is the key AI technology that enables the natural language understanding and generation capabilities behind Circle to Search, allowing it to comprehend users' visual search queries and provide relevant information.
