Cameras that can acquire a continuous stream of depth images are now commonly available, for instance the Microsoft Kinect. It may seem that one should be able to stream these depth videos using standard video codecs, such ...

The sense of touch is important in our everyday lives and its absence makes it difficult to explore and manipulate everyday objects. Existing online shopping practice lacks the opportunity for physical evaluation, that ...

This study is concerned with semantic modelling of virtual environments (VEs). A semantic model of a VE provides an abstract and high level representation of main aspects of the environment: ontological structures, behaviours ...

Path steering is an interaction task of how quickly one may navigate through a path. The steering law, proposed by Accot and Zhai [AZ97], is a predictive model which describes the time to accomplish a 2D steering task as ...

Photo-realistic techniques that use sequences of images captured from a real environment can be used to create virtual environments (VEs). Unlike 3D modelling techniques, the required human work and computation are independent ...

This paper describes a workflow and system to digitize, manage and render large and fast changing sets of building materials, e.g. brick, concrete, ceramic tiles, for VR architectural visualization. We describe the use ...

Models for animating the eyes of virtual characters often focus on making the face appear natural and believable. There has been relatively little work in computer graphics that investigates the relevance of the objects ...

This paper addresses the use of VR to facilitate design tasks in the early stages of a product design process. A preliminary exploratory study, involving over thirty interviews amongst four industrial partners, revealed ...
