Interaction Design for 3D User Interfaces

This book addresses the new interaction modalities that are becoming possible with new devices by looking at user interfaces from an input perspective. It deals with modern input devices and user interaction and design covering in-depth theory, advanced topics for noise reduction using Kalman Filters, a case study, and multiple chapters showing hands-on approaches to relevant technology, including modern devices such as the Leap-Motion, Xbox One Kinect, inertial measurement units, and multi-touch technology. It also discusses theories behind interaction and navigation, past and current techniques, and practical topics about input devices.

Ontology-based Procedural Modelling of Traversable Buildings Composed by Arbitrary Shapes

This book presents a new procedural modelling methodology capable of producing traversable buildings constrained by arbitrary convex shapes, based on a pure treemap approach. The authors establish a process to change the format of interior rooms, through wall number modification and offer an adaptation of a “fake-concave” technique to support non-convex building layouts. It will also include: • A proposal for an extensible building ontology to guide the methodology process and support the generation of other architectural style buildings (e.g. roman houses); • A presentation of an ontology-based grammar to provide the procedural modelling methodology with production rules; • Experimental computer managed processes for the stochastic generation of buildings. Most of the existing solutions regarding building interiors only focus on the generation of floor plans mainly composed of rectangular shapes. Yet there are a wide variety of ancient and contemporary buildings that are composed of shapes other than rectangles, both internally and externally. Ontology-based Procedural Modelling of Traversable Buildings Composed by Arbitrary Shapes will address this by providing the Procedural Modelling field with processes and techniques capable of properly supporting for example, digital preservation of cultural heritage or extensive virtual urban environment productions, specifically ones involving the generation/reconstruction of virtual buildings with such geometric requirements.
