Trust emerges from interaction. If trust in information systems is to be promoted, then attention must be directed, at least in part, to interaction design. This presentation will explore issues of trust in the interactions between users and systems from the perspective of interaction design. It will consider a variety of pragmatic aspects in interaction design that impact user trust, including...

1. Summary As explicitly stated in the title, this paper presented the advantages of treating user feedback as the first class citizen in the information integration systems. Compared with existing proposals in this area that only deal with specific type of user feedback and often only single user, the information integration systems proposed in this paper is capable of processing several diffe...

In this paper, we introduce GazeSpace, a novel system utilizing eye gaze to browse content spaces. While most existing eye gaze systems are designed for medical contexts, GazeSpace is aimed at able-bodied audiences. As this target group has much higher expectations for quality of interaction and general usability, GazeSpace integrates a contextual user interface, and rich continuous feedback to...

The needs and expectations of modern-day applications are changing in the sense that they not only need computing resources (be they processing power, memory or disk space), but also the ability to remain available to service user requests almost constantly 24 hours a day and 365 days a year. These needs and expectations of today’s applications result in challenging research and development eff...

Currently, the academic information system (AIS) at universities processes data to facilitate student’s activities. AIS was developed provide maximum service students. To optimize use of technology and ensure appropriateness provided services, it is necessary examine level improve quality. This study aimed analyze quality based on user perceptions expectations. Dissemination online questionnair...

Online Public Library Catalogues (OPACs) are widely used electronic library catalogues giving a wealth of remote access to library information resources. Users should be involved early in the OPAC development cycle process in order to ensure a usable and functional interface, as the integration of user-defined requirements of OPACs, along with the other Human-Computer Interaction considerations...

[Context and motivation] The starting point for software development is usually the system requirements. The requirements, especially non-functional requirements specified in a document are often incomplete and inconsistent with the initial user needs and expectations. [Question/problem] Experience at Siemens showed us that programmers working on software development often have trouble interpre...

Up till now designers often employed the principle “more is better” so they included any kind of information they could think of together with the items they were tasked to include, then transferred it all in detail. The end-result was the incorporation of all available data without considering the characteristics of the medium or the user. A smart graphic, however, puts a greater challenge on ...

Program synthesis from incomplete specifications (e.g. input-output examples) has gained popularity and found real-world applications, primarily due to its ease-of-use. Since this technology is often used in an interactive setting, efficiency and correctness are often the key user expectations from a system based on such technologies. Ensuring efficiency is challenging, since the highly combina...

We present a model of dynamic monopoly pricing for a good that displays network effects. In contrast with the standard notion of a rational-expectations equilibrium, we model consumers as boundedly rational and unable either to pay immediate attention to each price change or to make accurate forecasts of the adoption of the network good. Our analysis shows that the seller's optimal price trajec...
