I am a 3rd year Ph.D. student at VACT lab in Xi’an Jiaotong Liverpool University, supervised by Dr. Lingyun Yu. My research focuses on Scientific Visualization (SciVis) and Human-Computer Interaction (HCI). My work is dedicated to design and evaluate the spatial interaction techniques and visualization techniques tailored to specific scientific domains including astronomy and biomedicine within Cross-Reality (CR) and Virtual Reality (VR) environments.

Immersive Visualization and Interaction

Immersive environments, including virtual, augmented, and mixed reality, offer users an engaging avenue to interact with presented information. However, they also pose challenges in the context of data exploration, such as occlusion and imprecise inputs. Additionally, these environments break the constraints of limited space inherent in 2D screens, the indirect interaction methods of keyboards and mice, and the traditional approaches to collaborative exploration. Our focus revolves around delving into multiple facets of immersive visualizations and interactions, encompassing elements like engaging displays, embodied interaction, situated visualization, user behaviors, and experiences.

Spatial Data Exploration in Cross-reality (CR)

Cross-reality is thus more than simply merging various levels of reality-virtuality continuum (RVC), where spatial data is either positioned at a single space or moved to another place. Instead, it stands as an innovative and integrated environment for data presentation and exploration. Holding this vision, spatial data can appear in any form and at any corner of the environment, tailored to the specific needs of each scientific domain. For understanding data or completing tasks, it is crucial to allow users to control data transformations, such as transforming data across spaces or change visual representations. Yet, the most critical aspect to consider is why CR is the appropriate choice for the task and data. This rationale shapes all other design aspects: the choices of environment, visualization, and interaction designs.
