Flexible user interfaces that can be customized to meet the needs of the task at hand are particularly important for real-time group collaboration. This paper presents the user interface of the DISCIPLE (DIstributed System for Collaborative Information Processing and LEarning) system for synchronous groupware along with the multimodal human-computer interface enhancement. DISCIPLE supports shar...

The growth of end-user computing and the trend toward the use of packaged software have focused greater attention on issues related to user support. A varied user population is requiring more tailored support, yet vendor-supplied software with a generic interface is increasingly being used. Four case studies illustrate ways in which organizational forms of support can enhance or overcome the li...

Offering a new course on user-interface design presents several problems for a Computer Science department. As well as building student competency in user interface design and user interface evaluation, the course must give timely feedback to students while ensuring that staff and student workload remains manageable. We developed a course that uses a novel system of tutorials and group work to ...

Interface agents are computer programs that provide personalized assistance to users with their computer-based tasks. Most interface agents achieve personalization by learning a user’s preferences in a given application domain and assisting him according to them. In this work we adopt a different approach to personalization: how to personalize the interaction between interface agents and users ...

Ongoing efforts at our laboratory have been aimed at developing techniques that reduce the complexity of interaction between humans and computers. In particular, we have investigated the use of a gesture recognition system to support natural user interaction while providing rich information content. In this paper, we present additions to a platformindependent, gesture recognition system which p...

This chapter aims to offer a user-centred methodological framework to guide the design and evaluation of Brain-Computer Interface videogames. This framework is based on the contributions of ergonomics to ensure these games are well suited for their users (i.e., players). It provides methods, criteria and metrics to complete the different phases required by ae human-centred design process. This ...

This paper describes the development of a brain computer interface. The system allows the user to control a game character in a 3D virtual environment, as well as control a basic ‘Pong like’ bar in a simple 2D application. The user will have to adapt their thought patterns to be consistent, and to be able to successfully control the game. As the user moves through the game, various methods of b...

This paper focus on goal of Human computer interface system which are used to analysis a skill for human user by interacting with the system. It can be evaluate by problem solving, assessment activity, creativity and other process based on metrics in systematically. It can be used to develop an idea for software tool to evaluate the skill of human user through usability metrics. Keywords— Inter...

This study provides a framework for researchers who study the interactions of humans with computers to develop and evaluate user-centric user-interfaces by applying existing theories about telepresence, human-computer research, and characteristics of technology itself to produce social and spatial experiences similar to the ones computer users experience in the non-mediated world. An experiment...

With ubiquitous computing, users access their applications in a wide variety of environments. To cope with various and dynamic execution environments, the adaptive mobile user interface is desired to enhance human-computer interactions. This paper discusses the design of the context sensitive mobile user interface that will enable automatic adaptions to the environment. The challenges of this r...
