We present evaluation results of a multimodal route navigation system that allows interaction using speech and tactile/visual modes. Various functional aspects of the system were studied, related especially to the IO-modalities and their use as means of communication. We compared the users’ expectations before the evaluation with their actual experience of the system, and found significant diff...

This paper considers the creation and consumption of content on user generated content platforms, e.g., reviews, articles, chat, videos, etc. On these platforms, users’ expectations regarding the amount and timing of participation by others becomes germane to their own involvement levels. Accordingly, we develop a dynamic rational expectations equilibrium model of joint consumption and generati...

We report on the Application Generator (AG), a system that automatically creates, and then manages, user-customized applications requiring a speech interface. The AG is composed of four modular components: the Automatic Dialogue Generator (ADG), the Profile Manager (PM), the Information and Services Manager (ISM), and the Dialogue Manager (DM). The PM module encodes the user’s intent with a rep...

It has been argued that the promising benefits of Enterprise Systems (ES) implementations are overshadowed by their high failure rate. One of the commonly cited reasons for ES implementation failures is the end-user’s unwillingness to adopt or use systems. Considering that the appropriate management of expectations may play an important role in forming positive behavior toward newly implemented...

In Quality of Experience (QoE) research, the concept of ’expectations’ is frequently used but seldom defined with sufficient clarity and precision. In this paper, we present theoretical and conceptual approaches originating from various research fields that deal with expectations and its measurement. In addition, we also present results from our own empirical work to exemplify how to measure an...

Information retrieval systems are often evaluated through the use of effectiveness metrics. In the past, the metrics used have corresponded to fixed models of user behavior, presuming, for example, that the user will view a predetermined number of items in the search engine results page, or that they have a constant probability of advancing from one item in the result page to the next. Recently...

Whenever humans interact they form expectations which their behaviour is grounded in. This paper claims that this is also true for human-robot interaction (HRI). It introduces assumptions from expectation theory and illustrates how these can be tested in an HRI context. The paper aims to show that knowing the users’ expectations can help to design robots. Since user expectations depend on the r...

Much of the software people use for everyday purposes incorporates elements developed and maintained by someone other than the developer. These elements include not only code and databases but also data feeds. Although everyday information systems are not mission critical, they must be dependable enough for practical use. This is limited by the dependability of the incorporated elements. It is ...

background although there are various methods for painless delivery such as using entonox gas, most of the people are unfamiliar or concerned about it yet. objectives the purpose of this study was to assess maternal expectations and experience of labor analgesia with nitrous oxide. patients and methods in a clinical trial study, 98 pregnant women in active phase of delivery were studied randoml...

User feedback is a new direction employed to assist users in building data integration systems and to improve their quality. We claim that the first step to the efficient data quality improvement in a data integration system is the consistency of user’s expectations feedback because user(s) can have multiple expectations of the quality of the value and the content of the query results at the sa...
