We have built a framework for using 3D modelling applications in an immersive virtual environment. In this paper we compare our immersive user interface made for an existing application to its original 2D desktop counterpart. The immersive 3D user interface was built on top of a generic distributed rendering framework on a cave–like virtual reality system. A test scenario was designed for compa...

This paper presents an application of a user modelling web service in personalizing interfaces for users with age-related and physical impairment. The user model stores user profile in standardized format independent of application and device. It allows users to carry the profile with them irrespective of device and application. The user modelling web service is used to adapt interfaces of a se...

This paper introduces an approach for applying agent technology for user modelling in ubiquitous computing. It illustrates the research issues in distributing the knowledge about the user across active entities and distributed user-model acquisition and application methods, and specifies the agents using a defined communication framework for distributed user-modelling for ubiquitous computing. ...

In a Collaborative modelling environment, multiple users may interact in a virtual environment to deform or modify shared 3D objects (e.g., for modelling and visualization of virtual prototypes). The challenges to collaborative modelling are related mainly to four aspects: user interaction with the virtual modelling environment, 3D objects concurrent editing, consistency maintenance among clien...

Crowdfunding platforms have become important sites where people can create projects to seek funds toward turning their ideas into products, and back someone else’s projects. As news media have reported successfully funded projects (e.g., Pebble Time, Coolest Cooler), more people have joined crowdfunding platforms and launched projects. But in spite of rapid growth of the number of users and pro...

A longstanding objective of human-computer interaction research is to develop better dialog systems for end users. The subset of user modelling research specifically, aims to provide dialog researchers with models of user behaviour to aid with the design and improvement of dialog systems. Where dialog systems are commercially deployed, they are often to be used by a vast number of users, where ...

Folder navigation is themainway that personal computer users retrieve their own files. People dedicate considerable time to creating systematic structures to facilitate such retrieval. Despite the prevalence of both manual organization and navigation, there is very little systematic data about how people actually carry out navigation, or about the relation between organization structure and ret...
