Current programmable home appliances are often difficult to use. It is now possible to make them more usable by providing them with conversational capabilities based on collaborative discourse theory. This paper discusses an approach for designing programmable appliance interfaces towards supporting person-product collaboration, A central component of the approach is an adaptive menu, called Some...
An important factor in the success of human one-to-one tutoring is the tutor's ability to identify and respond to affective cues. However, current intelligent tutoring systems model students solely on their cognitive, and not affective, state. Automated facial expression analysis makes it possible for computers to identify affective cues by analysing images of learners' facial expressions. A new generation...
Diversity and evolution in database applications often result in multidatabase environment in which corporate data are stored in multiple, distributed data source. It is a formidable work to formulate query to access those multidatabase, especially when some complex constraints are involved. This article presents MQDP (multidatabase query design and processing), a graphical user interface to multidatabase...
The explosive growth of the Internet and the Web services technology provides the underpinnings to multimedia web services. However, due to the rich media types in multimedia content and the diversity and heterogeneity in terms of the types of client devices and network connections as well as the special needs and preferences that end users might have, it is very difficult and expensive to provide...
Ambient intelligence is nowadays an active research field. As a key matter of this concept, several approaches have been proposed for the development of learning architectures for the control of the devices in an intelligent building. In this paper, an evolutionary algorithm is analyzed as a candidate for the initial phases of the design of such architectures: fuzzy controllers for the devices are...
The technology of mobile computing can assist considerably the educational process in general, since both students and instructors may have access to educational software applications form anywhere at anytime through handheld devices or mobile phones. However, there may be drawbacks as well, such as difficulty of use. In this paper we examine the degree of usefulness of mobile facilities for students...
This paper presents a formalism for representing knowledge, intended for use in teaching interfaces. The driving concern in developing the formalism was to get an explicit method for sequencing the presentation of materials to be learned. The first criterion for doing the sequencing is that it satisfies a relation of constructability or learning support among the materials. If the relation is restricted...
At Pacific Northwest National Laboratory, we are researching and developing scientific computing environments for biologists and bioinformaticists. Important issues for us are how to motivate biologists to use new computational technologies and how to best incorporate and integrate disparate computational resources into computational biology research. In recent efforts, we have focused on the development...
This paper represents work in progress towards a complete remote control system designed to tele-operate robot manipulators. With this aim, a user interface has been designed, enabling the user to control a robot through the Web via any standard browser. Furthermore, in addition to the online control of robots, a virtual 3D representation of the environment, including the robot, allows the user testing...
This paper presents a quantitative complexity theory for human-machine interaction and validates the developed theory through experiments. Based on work in basic research an information-theoretic complexity measure C is introduced The main advantage of the novel measure is that it solely relies on information theoretic quantities and is independent from possibly unreliable subjective ratings or psychophysiological...
Fast computer networks and over performance computers enable computational grid establishment on non-dedicated and geographically distributed computers. This causes an increase in dynamic heterogeneity which makes resource management much more difficult. An additional problem is represented by a strong dependency of resource availability on a human as their owner. Concession of resources to the grid...
EMGs are a natural means of HCI because the electrical activity induced by the human's arm muscle movements can be interpreted to used as computer's control commands. In this paper, we present an on-line EMG-MOUSE system that controls movements of a cursor, which are interpretations of 6 pre-defined wrist motions: up, down, left, right, click, and rest. To emphasize a wearability, we designed the...
Experiences from simulation studies of industrial control systems and performing art oriented human-machine installation suggest how cybernetics may benefit from art and vice versa. We argue for a constructive and analytic multi-focus on control and communication in the animal and the machine aiming at a close integration of art, science and technology. An industrial simulation project for the design...
The work introduced here concerns the user interface requirements of older users of e-mail. The main goal is to understand better the e-mail needs of older people, and to form a foundation for further developments in simplified and rationalised e-mail interfaces. The approach involved working closely with older computer users to establish their essential requirements, attempting thus to reduce complication...
The design of Web-based user interfaces is of primary importance for achieving successful operation of Internet-based monitoring and control systems. Operators need to be able to act promptly on changing situations requiring remote actions to process plants. A formal development process is proposed to determine the minimum amount of information that needs to be presented at interfaces. The first stage...
An intelligent control scheme of the double power supplies system based on digital signal processor (DSP) and controller area network (CAN) bus is introduced in this paper. In this scheme, the power inverter can synchronously track the network precisely in double power supplies condition, and switch in double directions seamlessly (in less than 2.4 ms) between double power supplies. This control system...
