Hypertext offers users a simple, flexible way to navigate through electronic information systems but at the potential risk of becoming lost in the network of interconnected pieces of information. A study was conducted on information retrieval using a ...

We propose a support system for finding lost objects indoors. The system employs active RFID and ultrasonic position detection to detect the position of a lost object. The system illuminates the position by using Movinglight, which is normally employed ...

A control strategy for graphical applications running on remote computing resources is proposed, discussed and compared with other previous existing solutions. The advantages of this new strategy are the fact that the remote application is controlled ...

This paper describes a new out-of-core multi-resolution data structure for real-time visualization, interactive editing and externally efficient processing of large point clouds. We describe an editing system that makes use of the novel data structure ...

We describe a speech-based interface to an information visualization (infoVis) system. Users ask natural-language questions about a given data domain. Our interface then maps the questions into infoVis operations, which result in the display of data ...

Speech animation is traditionally considered as important but tedious work for most applications, because the muscles on the face are complex and dynamically interacting. In this paper, we introduce a framework for synthesizing a 3D lip-sync speech animation ...

We present a simple interactive approach to specify 3D shape in a single view using "shape palettes". The interaction is as follows: draw a simple 2D primitive in the 2D view and then specify its 3D orientation by drawing a corresponding primitive on ...

Image editing software is often characterized by a seemingly endless array of toolbars, filters, transformations and layers. But recently, a counter trend has emerged in the field of image editing which aims to reduce the user's workload through semi-automation. ...

Advanced human computer interaction requires automatic reading of human face in order to make the computer interact with human in the same way as human-to-human communication. We developed an automatic face tracking and lip reading system through a 3D ...

Rapid Serial Visual Presentation, or RSVP, is the electronic equivalent of riffling a book in order to assess its content. RSVP allows space to be traded for time and has tremendous potential to support electronic information browsing and search particularly ...

The complex nature of social and scientific spatial-temporal multivariate data calls for highly interactive integrated information visualization (InfoVis) and geo-visualization (GeoVis) tools and applications. Our research concentrates on improving visual ...

Geometry models of existing objects are typically acquired into computer using 3D scanning techniques whose immediate outputs are points. Because the 3D scanning process is prone to error and heavily dependent of the accuracy of the scanning device, ...

A number of problems such as planning, scheduling and system maintenance have in common a dynamic set of resources and the need to optimize the use of these resources. The Dynamic Optimal Resource Utilization System (DORUS) is an architecture suitable ...
