Paper Title
Virtual Space Expansion and Viewpoint Tracking – Taking "Virtual Portal" as an Example
Abstract
The research work "Virtual Portal" is a virtual window that can be projected on the wall and combined with
Viewpoint Tracking technology. It has the capability to create an extended space that can instantly display a flat image in
accordance with any viewing angle. The inspiration for the "Virtual Portal" artwork comes from the desire to connect past
experiences while watching outside the window, and its spatial visual experience and feedback, which can also affect the
psychological state of perception. Changes in the scenery outside the window, even with slight fluctuations in the viewpoint
caused by small breaths, can instantly affect the spatial experience and alter the mood. With the moving perspective when
walking, a person is able to experience perspective and fractal changes, leading to the abstract experience of rich
space.Using the HTC VIVE Tracker, the way to present images with only a single perspective, this work hopes to use the
form of extended space to experience fractals through spatiality, and to make abstract images concrete and form a
"composite of complex layers of minds".
