1. Research Plan

1) Research Objective

The ultimate goal of this study is to propose design guidelines through the analysis of interaction sequences in XR-based memory visualization interfaces. Specifically, it seeks to measure the effects of information hierarchy levels and user interaction sequence design for memory visualization on autobiographical continuity and co-presence, using physiological indicators (EEG, EDA), behavioral data, and subjective evaluation metrics. Based on the derived data, the study will establish core design parameters and a UX evaluation framework, and present implementation guidelines alongside a working prototype, thereby laying the foundation for XR-based memory spatialization systems.

2) Research Necessity and Significance

In contemporary digital environments, personal memory cues are proliferating exponentially, fragmented across visual, textual, and sensory data. Existing lifelogging, cloud, and AR systems support only fragmentary recall and fail to provide narrative continuity across the lifespan or collaborative interfaces with AI. While research has attempted to utilize images to generate and reconfigure memories within 3D environments, there is a lack of empirical studies validating the effects of such systems on autobiographical continuity and co-presence through physiological, behavioral, and subjective measure, resulting in an absence of design standards. To address this gap, the present study aims to systematically analyze user–system interaction sequences, structure the step-by-step processes of memory exploration, editing, and reconfiguration, and identify design principles optimized for each stage of continuous interaction. Ultimately, this research will establish practical design criteria for immersive experiences of visualized memory, construct a user experience-based design and evaluation framework, and propose 3D memory restoration guidelines and AI interaction principles. These contributions are expected to advance the research and system design of XR memory spatialization and posthuman interfaces.

Key Concept Definitions

Autobiographical continuity: The psychological characteristic by which individuals integrate representations of past, present, and future selves into a coherent life narrative. This narrative consistency enables the maintenance of self-identity and the incorporation of new experiences into existing autobiographical memory structures, ensuring temporal and emotional stability.
Co-presence: The perceptual and affective assurance that one’s actions within a virtual environment are simultaneously interacting with an “other” (real, virtual, or AI). This sense of simultaneous coexistence is grounded in real-time feedback mechanisms of space, action, and interaction, and plays a central role in enhancing immersion and social connectedness.
