HyPockeTuner: Bringing Hyperparameter Optimization to Mobile Devices

Hyperparameter optimization (HPO) is a long-running process that can span hours or even days. While recent Human-in-the-Loop HPO systems enable monitoring and steering of the process, they are typically designed for desktop environments, which limits their effectiveness in managing prolonged experiments in practice. T…

Unpacking Visual Metaphors in Infographics: A Design Space

Visual metaphors illuminate infographics by leveraging graphical representations from more familiar source domains (e.g., a dandelion) to explain concepts in more abstract target domains (e.g., information propagation). However, designing effective visual metaphors remains a challenge, especially for novice designers,…

FluidTrack: Investigating Child-Parent Collaborative Tracking for Pediatric Voiding Dysfunction Management

Daytime urinary frequency syndrome (DUFS) is a prevalent pediatric voiding dysfunction. Managing DUFS involves sufficient water intake and monitoring voiding and defecation behaviors, which can be challenging for preschool-aged patients to perform throughout the day for prolonged periods. To address this problem, we c…

DataSentry: Building Missing Data Management System for In-the-Wild Mobile Sensor Data Collection through Multi-Year Iterative Design Approach

Mobile sensor data collection in people’s daily lives is essential for understanding fine-grained human behaviors. However, in-the-wild data collection often results in missing data due to participant and system-related issues. While existing monitoring systems in the mobile sensing field provide an opportunity to det…

Data Formulator 2: Iterative Creation of Data Visualizations, with AI Transforming Data Along the Way

Data analysts often need to iterate between data transformations and chart designs to create rich visualizations for exploratory data analysis. Although many AI-powered systems have been introduced to reduce the effort of visualization authoring, existing systems are not well suited for iterative authoring. They typic…
