''Target-aware'' pointing techniques, like Bubble Cursor or Semantic Pointing, outperform traditional pointing by leveraging knowledge of target locations. Yet the lack of application-agnostic widget geometry information limits their adoption across the desktop. We present TargetFinder, a computer vision-based system for real-time detection of GUI widgets. TargetFinder leverages several fine-tuned YOLO networks trained on a new dataset of 520 annotated desktop screenshots (~38,000 annotations) spanning Windows, macOS, Ubuntu, and web interfaces. TargetFinder uses lightweight screen monitoring and low-latency detection, achieving millisecond responsiveness suitable for interactive use. Evaluations show that TargetFinder outperforms the baseline methods (OmniParser and REMAUI), while system-wide implementations of Bubble Cursor and Semantic Pointing demonstrate the feasibility of deploying universal target-aware techniques that work across applications. We release the dataset, models, annotation tool, and an open-source library for research and applications.
Squint and cataract are major ocular disorders that majorly affect visual perception and interaction capability. This paper proposes a real-time video-based automated detection system for squint and cataract detection based on computer vision and image processing methods. The pro…
Most educational technology for children is built around visual interfaces, which excludes the many children worldwide who live with visual impairment -- an estimated 1.4 million children are blind and many more have low vision. We present Kutti AI, a voice-first learning compani…
E-textiles and wearable sensing technologies enable flexible, customizable interfaces for human-computer interaction, with capacitive sensing offering precise touch and pressure detection. While machine knitting provides scalable, mechanically tunable structures ideal for such se…
Battery-free RFID systems offer a scalable and maintenance-free approach to interaction. We present KnitID, a machine-knitted textile RFID antenna design that enables on-body authentication, localization, and interaction. Unlike prior antenna designs, KnitID achieves a compact an…
We present AutoJourn, a demonstration system for multi-perspective news generation and bias-aware evaluation using large language models (LLMs). The system tackles three core challenges in responsible automated journalism: extracting diverse perspectives from unstructured social…
LLM-based agents have rapidly improved at operating individual digital environments such as mobile applications, desktop systems, and smart homes. However, real-world user goals often span multiple devices: information may come from a phone, be processed on a desktop, and the res…
