1. Overview
▶ Problem Statement
- Rapid and accurate interaction with virtual objects is a crucial factor in VR.
- However, certain interactions in VR have limitations:
- Users must physically move if an object lies outside their reachable area.
- If an object is occluded by other virtual objects in a 3D environment, the user must exert considerable effort to reach and interact with it.
▶ Portallite
- The user selects a desired region of interest (ROI) via a planet-like representation that provides a “summarized” version of the virtual environment.
- A “Satellite” is generated to control the ROI—a concept we call Satellite WIM.
- Based on minified and portal-like worlds, the ROI is displayed close to the user, enabling them to interact with virtual objects.
- This approach allows the user to feel as though they are directly manipulating large-scale or distant areas in the virtual environment.
▶ Tools
- Oculus Quest 2 and Leap Motion
- Unity (2021.3.61f1)
2. Research & Development Process
▶ Survey
- Searched academic papers and books via Google Scholar, IEEE Xplore, and ACM Digital Library.
- 🔗Link to the Paper Search summary
▶ Development
- Planet: A globe that maps the user’s large flat virtual environment onto its surface (a second viewpoint).
- Satellite: Allows the user to inspect and control the chosen ROI around the planet.
