We describe a prototype software system for investigating novel human-computer interaction techniques for 3-D geospatial data. This system, M4-Geo (Multi-Modal Mesh Manipulation of Geospatial data), aims to provide a more intuitive interface for directly manipulating 3-D surface data, such as digital terrain models (DTM). The M4-Geo system takes place(More)
We describe M4, the multi-modal mesh manipulation system, which aims to provide a more intuitive desktop interface for freeform manipulation of 3D meshes. The system combines interactive 3D graphics with haptic force feedback and provide several virtual tools for the manipulation of 3D objects represented by irregular triangle meshes. The current(More)
In this paper, we report our ongoing research into multi-sensory investigation of geoscientific data. Our Geoscientific Data Investigation System (GDIS) integrates threedimensional, interactive computer graphics, touch (haptics) and real-time sonification into a multi-sensory Virtual Environment. GDIS has been used to investigate geological structures(More)
In this paper, we compare the mental maps created by sighted participants with the maps created by participants with visual impairments during the study of an auditory platform game. The game uses audio cues to convey a 2D side-scrolling view of the spatial layout of the game world. We studied three groups with 9 participants each: a control group of(More)
Control and tunability of the catalytic oxidation of CO by gold clusters deposited on MgO surfaces grown on molybdenum, Mo(100), to various thicknesses are explored through temperature-programmed reaction measurements on mass-selected 20-atom gold clusters and via first-principles density functional theory calculations. Au(20) was chosen because in the gas(More)
Despite advances in 3-D computer graphics, students in introductory calculus classes still learn mainly by working with equations and the occasional 2-D diagram. When moving to more complex levels of calculations, we observed a need for aiding the students' understanding via 3-D visualization, but without the use of powerful, yet complicated, professional(More)
In this paper, we report on our ongoing research into multimodal investigation of geoscientific data. Our system integrates three-dimensional, interactive computer graphics, touch (haptics) and real-time sound synthesis into a multimodal interface. We present applications of multimodal investigations of geoscientific data that pertain to surface meshes on(More)
