Faults, which role greatly in the generation and spatial distribution of mineral resources, are always related to the lineament interpreted from remote sensing data. This paper introduces an improved segment tracing algorithm (STA) to interpret lineament from remote sensing data (DEM) in Gejiu tin mine, China. In this analysis, a lineament is treated as a straight line in the horizontal plane and its dip is not considered. A fault is created by connecting several lineaments, which appear to belong to the same system, using the criteria of distance and directional angle. The proposed method was applied to mines in Gejiu tin mine, a area of Triassic limestone with tin mine. A correlation exists between interpreted fault orientations and (1) the predominant azimuth of joints appearing on the tunnel walls of a tin deposit in the limestone area and (2) the orientation of main tin deposits. Furthermore, the proposed method is capable of calculating the intersection pattern of fractures at an arbitrary level below the ground surface.
With the emerging trend in Human-Computer Interaction (HCI) shifting focus from usability to facilitating meaningful experiences, the notion of embodied cognition provides designers and researchers with valuable insight into how the body-mind interplay can influence meaning-making during embodied experiences. This paper presents an approach to designing embodied interactions with ambient media. Building on theories of embodied cognition and cognitive semantics, we developed our approach by conducting a series of studies, including an interpretive case analysis, empirical research into audience experience and design ideations, as well as designerly reflections on design. Our findings showed that an embodied approach is applicable for designing meaningful interactions, by coupling bodily engagement with metaphorical meanings. Design implications and future work are also presented.
While embodiment is widely accepted as an important theoretical basis in interaction design and HCI, few studies explore movement-based meaning making in interacting with ambient media. Building on embodied interaction, this paper aims to identify and analyze key characteristics of audience experience and the role of bodily movement in meaningful making through an empirical study. A prototype "Piano Staircase" is built for experience tests and empirical data collection. Experiments with 30 participants have been conducted. The findings show bodily interaction can activate embodied conceptual mapping and facilitate meaningful audience experience. The model of embodied meaning making provides possibilities for analyzing meaningful experience with ambient media.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
