报告题目：Interpreting and Steering AI Explanations with Interactive Visualizations

报告摘要：

Artificial Intelligence (AI) has advanced at a rapid pace and is expected to revolutionize many biomedical applications. However, current AI methods are usually developed via a data-centric approach regardless of the usage context and the end users, posing challenges for domain users in interpreting AI, obtaining actionable insights, and collaborating with AI in decision-making and knowledge discovery.As a visualization researcher, I aim to address this challenge by combining interactive visualizations with interpretable AI. In this talk, I discuss and demonstrate the prospects for interactive visual explanations in the application of biomedical AI via real-world case studies. I present two methodologies for achieving this goal: 1) visualizations that explain AI models and predictions and 2) interaction mechanisms that integrate user feedback into AI models. Despite some challenges, I will conclude on an optimistic note: interactive visual explanations should be indispensable for Human-AI collaboration. The methodology discussed can be applied generally to other applications where human-AI collaborations are involved, assisting domain experts in data exploration and insight generation with the help of AI.

报告题目：When Data Meets Reality: Augmenting Dynamic Scenes with Visualizations

报告摘要：

We live in a dynamic world that produces a growing volume of accessible data. Visualizing this data within its physical context can aid situational awareness, improve decision-making, enhance daily activities like driving and watching sports, and even save lives in tasks such as performing surgery or navigating hazardous environments. Augmented Reality (AR) offers a unique opportunity to achieve this contextualization of data by overlaying digital content onto the physical world. However, visualizing data in its physical context using AR devices (e.g., headsets or smartphones) is challenging for users due to the complexities involved in creating and accurately placing the visualizations within the physical world. This process can be even more pronounced in dynamic scenarios with temporal constraints.

In this talk, I will introduce a novel approach, which uses sports video streams as a testbed and proxy for dynamic scenes, to explore the design, implementation, and evaluation of AR visualization systems that enable users efficiently visualize data in dynamic scenes. I will first present three systems allowing users to visualize data in sports videos through touch, natural language, and gaze interactions, and then discuss how these interaction techniques can be generalized to other AR scenarios. The designs of these systems collectively form a unified framework that serves as a preliminary solution for helping users visualize data in dynamic scenes using AR. I will next share my latest progress in using Virtual Reality (VR) simulations as a more advanced testbed, compared to videos, for AR visualization research. Finally, building on my framework and testbeds, I will describe my long-term vision and roadmap for using AR visualizations to advance our world in becoming more connected, accessible, and efficient.
