A gaze‐based interaction method for large‐scale and large‐space disaster scenes within mobile virtual reality

Abstract

A three‐dimensional (3D) visualization of disaster scenes based on mobile virtual reality (VR) can improve the application scenarios and emergency service capabilities of traditional 3D visualization of disaster scenes. Because a smartphone needs to be placed into a mobile head‐mounted display, conventional touch scene interaction cannot be used by mobile VR, and the user's gaze usually serves as the default scene interaction method. However, the existing gaze‐based interaction methods for mobile VR scenes are passive scene interaction methods and cannot meet the basic interaction requirement for actively roaming through and exploring large‐scale and large‐space disaster scenes. Therefore, this study focuses on gaze‐based mobile VR interactions to satisfy the various interaction requirements of large‐scale and large‐space disaster scenes. First, a dynamic user interface (UI) generation method for gaze interaction in large‐scale and large‐space disaster scenes is proposed to solve the problem of the active exploration of mobile VR disaster scenes. Second, disaster scene exploration and disaster information query methods based on a dynamic UI and gaze are proposed. Finally, using a flood disaster as an example, a prototype system and associated experiments are discussed. As indicated by the experimental results, the gaze‐based mobile VR interaction methods addressed in this study can effectively support users in actively roaming through and exploring large‐scale and large‐space disaster scenes, disaster simulation analysis, and the interactive querying of disaster information within mobile VR, making the effective interaction of mobile VR disaster scenes possible.

Evaluating the Usability of a Gaze-Adaptive Approach for Identifying and Comparing Raster Values between Multilayers

“…Eye tracking has been used as an input modality for decades [17,18]. There is increasing interest in gaze interaction, especially in virtual/augmented reality (VR/AR) [19][20][21][22][23], partly due to improvements in tracking accuracy, portability and affordability. One critical issue in gaze interaction is avoiding unintended selection (i.e., a user looking at an object does not mean he or she wants to interact with it), which is referred to as the Midas Touch problem [17].…”

Effects of Restorative Environment and Presence on Anxiety and Depression Based on Interactive Virtual Reality Scenarios

“…People could interact with the virtual space through gaze interaction, gesture interaction, interactive devices, etc. [68]. At the same time, people's movement and proprioception are closely linked, and the perception of self and environment is enhanced, arising from the presence and positive emotions [69].…”
