[G01-P02] Application of GIS-Globe Stereoscopic Viewer for Earth Science and Education -Use of Original Video or Social Media Contents-
Keywords:drag and drop, Stereo vision, video contents, Visual teaching materials, Virtual Reality, Digital Transformation
1. Introduction
A technique was proposed to use ordinary single images taken of rotating or moving objects created stereoscopic views of these objects, alternatively, to use filmed while rotating or moving (Ryoki (2019a, 2019b, 2019c)).
Ryoki, et al. (2022) showed the direction to develop and apply this to vocational training in the DX era.
Here, we report on the presentation of teaching materials using this technique in geoscience education at high schools and related professional education at universities and other institutions.
2. Overview of the stereoscopic viewer SVd
Stereoscopic images can be viewed by playing back normal video images of a rotating object, side by side with a slight time interval between them (Ryoki (2019a)). This application, Stereoscopic Video (SVd), is available on the World Wide Web (Ryoki (2021, 2022a)). This viewer can stereoscopically view video files on a PC that meet the above conditions, as well as videos including those for VR provided by You Tube (2022), a social media service that has now become universal (Figure 1).
In SVd, the rotation angle of the playback image can be adjusted. Therefore, images captured and filmed in any orientation can be viewed as if they were moving horizontally.
SVd can read 2D barcodes as well as SVw. The added ability to view YouTube content and local files such as mp4 using drag & drop (Figures 2 and 3) improves convenience when used in an educational setting.
The SVd screen can be rotated. Therefore, stereoscopic images that move up and down can be viewed by rotating them as necessary (Ryoki, et al., 2022).
3. Use of map contents
In the education of earth science, geography, civil engineering, and architecture, maps and their representations of natural features and artificial structures are often used as teaching materials. In SVw, GSI Globe (GSI, 2017) can be used as map content, which can be handled in the same way as conventional stereoscopic teaching materials using aerial photographs (Ryoki, 2019). GSI Globe can be used as a teaching material in various fields because various geographic information created by other organizations can be placed on top of the topographic map that serves as the base map.
It can also be used in conjunction with geographic information editing tools such as QGIS (QGIS Project, 2023), a free open source program, to create original educational materials.
As shown in Figure 4, it is convenient to use Stereoscopic Viewer (SVw) created by Ryoki (2019a) when using GSI Globe for stereoscopic viewing. The URL of the GSI Globe to be displayed can be appended as a parameter to the URL of SVw. The URL of GIS Globe can include specifications of various conditions for rendering.
The URL of SVw can also be displayed as a two-dimensional barcode for easy viewing on each PC.
The latitude and longitude of the viewpoint, calculated by the algorithm proposed by Karney (2013), can be displayed when a bird's-eye view of the map is displayed in SVw.
Stereoscopic viewing will be abled when rendering GoogleEarth (Google LLC, 2017) or Street View of GoogleMap (Google LLC, 2005), in two WWW browsers using geographic coordinates and pupil position created in SVw.
4. Cautions for young people
Two images are recognized as three-dimensional with higher-order image processing is performed in the brain when the left and right eyes perceive individual images (Tanabe and Fujita (2004), Hirouchi (2013)). Considering these findings, we cannot deny the possibility that young people, whose brain processing system is not fully developed, may be inhibited from the natural development of their brain processing system by viewing two flat images with their left and right eyes separately using the technique described here to obtain a sense of 3D.
Therefore, it is desirable to use this method at least in high school or later educational settings.
