Microscope Upcycling: Transforming legacy microscopes into automated cloud-integrated imaging systems

Fri, 18 Apr 2025 00:00:00 +0000

Computerized microscopes improve repeatability, throughput, antisepsis, data analysis and data sharing in the biological laboratory, but these machines are cost-prohibitive in most academic environments. This is a barrier into collecting the large and consistent datasets required for machine learning analyses of microscopy data. We demonstrate hardware modifications and software to bring the features of modern computerized microscopes to decades-old legacy laboratory inverted microscopes. We demonstrate automation of X-Y positioning, focus stacking, image acquisition and image storage.

Generating Together: Lessons Learned from Developing an Educational Visual Novel with AI Collaboration

Fri, 28 Feb 2025 00:00:00 +0000

Visual novels are a popular game genre for educational games. However, they often feature pre-authored plot structures that cannot dynamically adjust to the player's progression through learning objectives. Employing procedural storytelling techniques boosts plot dynamism, but this comes at the cost of needing a larger repository of content (dialogue and images) to support different learning progressions and objectives. In this paper, we present postmortem-style case studies describing the lessons we learned from attempting to integrate large-language models (LLMs) and text-to-image models into the development of an educational visual novel about responsible conduct of research. Specifically, we discuss our experiences employing generative AI in our dialogue, character sprite, and background image creation processes.

Academical: A Dynamic Interactive Narrative Game for Responsible Conduct of Research Training

Fri, 28 Feb 2025 00:00:00 +0000

Our demo showcases a choice-based interactive narrative game created to teach responsible conduct of research and research ethics. It re-imagines the experience of a game previously published in the literature, using a content-selection system that dynamically constructs dialogue choices during play. Our goal is to provide players with more opportunities to experience agency than they would have with the original game's hand-authored branching narrative structure. Primarily, our system implements a conversation thread-switching mechanic that allows players to fluidly enter/exit conversation topics as one would in a real-life conversation.

Building Visual Novels with Social Simulation and Storylets

Fri, 28 Feb 2025 00:00:00 +0000

Simulationist interactive narrative systems allow game makers to craft reactive stories driven by simulated characters and their social dynamics. These systems produce narrative experiences that feel more emergent but may lack a coherent plot structure. We explored how to combine the emergent possibilities of social simulation with a procedural narrative system that affords writers strong authorial control over the plot. We did this by developing a Unity extension called Anansi that helps people create social simulation-driven visual novels. It enables users to inject simulation data into their story dialogue using logical queries and parameterized storylets written using Ink. The paper describes an overview of our extension and how we empower writers to drive narrative progression using cascading social effects from player choices.

The feasibility, usability, and clinical utility of traditional paper food and symptom journals for patients with irritable bowel syndrome

Fri, 14 Feb 2025 00:00:00 +0000

BACKGROUND: Paper food and gastrointestinal (GI) symptom journals are used to help irritable bowel syndrome (IBS) patients determine potential trigger foods. The primary aim of this study was to evaluate the feasibility, usability, and clinical utility of such journals as a data collection tool. A secondary aim was to explore a method for analyzing journal data to describe patterns of diet and symptoms. METHODS: Participants (N=17) were asked to log three sets of 3-day food and symptom journals over a 15-day period. Feasibility was evaluated by journal completion rates, symptom logging compliance, and logging fatigability. The feasibility, usability, and clinical utility of journaling were also assessed by a customized evaluation and exit interview. For each journal, regression analyses were conducted to examine relationships between key meal nutrients and subsequent symptoms. KEY RESULTS: Most participants were young (mean age 35±12) Caucasian (N=13) women (N=14). Journal completion...

Opportunities to design better computer vison-assisted food diaries to support individuals and experts in dietary assessment: An observation and interview study with nutrition experts

Fri, 6 Dec 2024 00:00:00 +0000

Automatic visual recognition for photo-based food diaries is increasingly prevalent. However, existing tools in food recognition often focus on food classification and calorie counting, which may not be sufficient to support the variety of food and healthy eating goals people have. To understand how to better design computer-vision-based food diaries to support healthy eating, we began to examine how nutrition experts, such as dietitians, use the visual features of food photos to evaluate diet quality. We conducted an observation and interview study with 18 dietitians, during which we asked the dietitians to review a seven-day photo-based food diary and fill out an evaluation form about their observations, recommendations, and questions. We then conducted follow-up interviews to understand their strategies, needs, and challenges of photo diary review. Our findings show that dietitians used the photo features to understand long-term eating patterns, diet variety, eating contexts,...
