In this study, we attempted to improve the effectiveness of geographic learning through virtual tactile experiences by combining maps and force-sensing devices. We developed a prototype interactive teaching material that combines physical experience with a "topographic relief" produced from 3D printer data released by the Geospatial Information Authority of Japan (GSI), and force-sensing experience generated from visual geographic data and elevation data. This kind of interactive teaching material, which combines visual and tactile, physical and virtual, aims to change the vertical learning style of each unit of study in geography, and to enable students to learn the relationship among various geographical information in a cross-sectional manner.
Currently, there are only a limited number of maps and models used for each unit of study when conducting geography and topography studies. Furthermore, there is a limit to the information that can be obtained from a single type of map. In other words, in order to understand the cause-and-effect relationship between maps, one must study several types of maps in conjunction with each other. The purpose of this research is to create content that allows students to understand the cause-and-effect relationship between maps and maps, rather than maps for each unit of study through a series of experiences.
In this study, we believe that the learning effect can be enhanced not only by using only maps but also by combining the experience of touching the unevenness of the terrain. The purpose of the research is to create content that enables understanding of the causal relationship between maps and maps, rather than maps by learning unit through a series of experiences.
How to experience
The experiencer can feel the unevenness of the terrain through the grasping device. The following is the experience procedure.
①A map is displayed on the monitor
②Having the root of a grasping device
Lower it slowly until you feel it
Be careful not to touch the display
③Move the pen on the map
④Switch maps by operating the keyboard
Description of the three types of maps
The map data used in this study was referenced from the Geospatial Information Authority of Japan (GSI).
the standard map, you can learn about prefectures, cities, mountain ranges and rivers. The map also provides an understanding of the differences in elevation and sea level by color. This allows the user to visually understand the unevenness of the terrain. At the same time, visitors can experience the unevenness of the terrain through Phantom.
The vegetation distribution map shows the ratio of trees to the ground surface. The ratio of trees can be understood by color. Through Phantom, visitors can experience the unevenness of the terrain. At the same time, they can understand the tree ratio as visual information.
The land coverage map shows what land is covered by. It is possible to understand how the land is utilized by color. The experiencer can experience the unevenness of the terrain through Phantom. At the same time, they can understand land use cases as visual information.
By combining vegetation maps as well as standard maps with basic map information, it is possible to understand that tree ratios are related to elevation differences. In addition, by combining the land coverage map with the urban area and river information, the user can learn that the tree ratio is deeply related to land formation.
Therefore, by comprehensively studying the three types of maps, the user can learn basic, natural, and man-made information from a single map data.
