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)
In this paper, we report our ongoing research into multi-sensory investigation of geo-scientific data. Our Geoscientific Data Investigation System (GDIS) integrates three-dimensional, interactive computer graphics, touch (haptics) and real-time sonification into a multi-sensory Virtual Environment. GDIS has been used to investigate geological structures(More)
187 and anthropogenic forcing factors (for example, land-use change, forest ®res, sulphate aerosol concentrations and nitrogen deposi-tion). However, our results indicate that it will be essential to accurately represent previously neglected carbon-cycle feedbacks if we are to successfully predict climate change over the next 100 years.

In this article, the author describes his ongoing efforts to combine high-quality 3D graphics, haptics (from the Greek word haptesthai, to grasp or to touch), and sonification (the use of sound for "visualization") into multisensory systems to interactively manipulate geoscientific data. These systems could facilitate many complex tasks that geoscientists(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)
