This thesis focuses on designing and implementing a Mixed Reality Tour Guide for Knowledge Graphs, utilizing both the Virtual Agent Framework and the Social Bot Framework. It involves creating a virtual environment where knowledge is displayed and interacted with, enhancing engagement and retention. The goal is to develop a system that supports interactive knowledge acquisition, allowing users to navigate through tours and engage with individual knowledge elements. This work represents a novel intersection of MR, AI, and educational technology, paving the way for innovative learning strategies.

Goals & Objectives

  • Develop an MR-based tour guide for visually representing knowledge maps.
  • Enable interactive navigation and engagement with knowledge elements.
  • Evaluate the effectiveness of the system in enhancing learning experiences.


Possible Research Questions

  • How can MR be integrated with knowledge graphs to provide an engaging learning experience?
  • What are the optimal interaction patterns for navigating through knowledge graphs in MR?
  • How does the MR-based system impact knowledge acquisition and retention?


Methodology & Approach

  • Review research on MR in education, knowledge graph visualization, and intelligent virtual agents.
  • Exploration of existing technologies and frameworks in the context of interactive learning.
  • Comparison of different MR applications in educational settings.
  • Identification of strengths and weaknesses in existing solutions.
  • Qualitative and quantitative methods for understanding user interaction.
  • Development of MR prototypes
  • User testing and iterative design to enhance usability.


Data Collection Methods and Sources

  • Surveys, interviews, and observation for user feedback.
  • Collection of interaction data within the MR environment.


Tools, Models, or Frameworks to be Employed

  • AI and ML algorithms for intelligent agent interaction.
