Speech Title: Re-invigorated 2D Barcodes: Innovations and Applications

Speech Abstract:  Barcodes have long provided an effective image-based interface for communication of digital data. The traditional one-dimensional universal product (bar)code (UPC) has now been in use for over 50 years. With the proliferation of SmartPhones and tablet devices, these days the focus is increasingly on two-dimensional barcodes. Quick response (QR) codes dominate the 2D barcode application space with myriad applications, including those in advertising and promotion, financial transactions, and connectivity. With the adoption of GS1 standards, 2D barcodes are also poised to play an increasingly prominent role in product labeling, tracking, validation, and in providing richer information to consumers. In this talk, we highlight, how advancements in camera, display, and print technologies are also enabling new innovations in 2D barcodes that can enhance their data carrying capacity and functionality enabling new applications. Specifically, we present a dual-modulation approach that exploits increasing spatial resolution to increase data capacity two-fold, in-situ and without disrupting existing 2D barcode applications. We also highlight how color capture, inherently available in mobile device cameras, can be effectively used to also increase capacity, both individually and in combination with the dual modulation. We highlight several emerging applications for the proposed innovations, particularly, highlighting recent work on combating quishing, i.e., QR code based phishing attacks.

Keynote Speaker III

Prof. Cheng-Hsuan Li
NTCU

Dr. Cheng-Hsuan Li is a Chair Professor at the Graduate Institute of Educational Information and Measurement and Director of the Center for Institutional Affairs at National Taichung University of Education, Taiwan. He served as Director-General of the Department of Information and Technology Education, Ministry of Education, Taiwan, from August 2022 to January 2024. He assisted in the planning and implementation of Taiwan’s Digital Learning Enhancement Plan for Grades 1–12 Students (2022–2025) and is currently the Principal Investigator of the Educational Big Data Project under Taiwan’s AI Talent Ark Project (2026–2029). In 2023, he led the development of TALPer, a generative AI Companion embedded in the Taiwan Adaptive Learning Platform (TALP) for nationwide K–12 use. Since its nationwide launch, TALPer and its AI Genies—such as self-directed learning, drawing, reading and thinking, and joyful learning genies—have supported over 750,000 teachers and students across Taiwan. His research focuses on artificial intelligence in education, statistical learning, educational measurement, learning analytics, adaptive learning systems, AI-supported assessment, and human-AI teaming. He advocates trustworthy and human-centered educational AI that supports personalized learning, teacher decision-making, self-regulated learning, and deeper student understanding.

Speech Title: Designing the Next Generation of AI Learning Environments: Multi-Agent Systems, Multimodal Generation, and Vibe-Coded Interactive Learning

Speech Abstract: What if an AI learning companion could identify a student's difficulty, generate an interactive mathematical model on demand, and use the resulting interaction to guide the next learning step?

This keynote explores how multi-agent systems, multimodal generation, vibe-coded interactive learning, and educational measurement can shape adaptive AI learning environments. Drawing on TALPer, an AI learning companion integrated into the Taiwan Adaptive Learning Platform (TALP), it discusses how AI can scaffold learning and generate manipulable mathematical models or scientific simulations in response to specific difficulties. Multimodal generation also supports visual, audio, and presentation materials, while persona-based multi-agent systems create collaborative scenarios involving virtual students.

Beyond content generation, the keynote examines a shift from predominantly summative assessment toward formative, process-oriented assessment. Item Response Theory (IRT) and Cognitive Diagnosis Models (CDMs) provide foundations for proficiency estimation and skill diagnosis; analyses of dialogue and interaction processes offer complementary evidence of how understanding develops. Together, these approaches suggest a feedback loop connecting diagnosis, on-demand interactive generation, learners' actions, and adaptive guidance.

The keynote concludes with a vision of human-centered AI environments that support exploration, collaboration, and deeper learning while addressing assessment validity and cognitive offloading.
