In this work, we investigate whether the cultural idiosyncrasies found in humanhuman interaction may be transferred to human-computer interaction. With the aim of designing a culture-sensitive dialogue system, we designed a user study creating a dialogue in a domain that has the potential capacity to reveal cultural differences. The dialogue contains different options for the system output acco...

Providing adaptive support in Exploratory Learning Environments is necessary but challenging due to the unstructured nature of interactions. This is especially the case for complex simulations such as the DC Circuit Construction Kit used in this work. To deal with this complexity, we evaluate alternative representations that capture different levels of detail in student interactions. Our result...

The complex structure of longitudinal data with associated discrete covariates requires developing visual methods for a better understanding of underlying structures. In this paper, a simple and flexible method, linked brushing, was studied for such datasets to detect the mean structure. Methods were applied to a random dataset from The Panel Study of Income Dynamics (PSID), which was first use...

1. ABSTRACT This paper presents a novel method of improving classroom technology access in developing regions for use in distance and co-located education. By placing a mouse on each student’s desk in a classroom and connecting those mice to a single computer, the system affords simple anonymous and non-anonymous student interaction with a remote or co-located teacher. User interaction features...

This paper puts forward a framework for the integration of pedagogy and software design to support educationally valuable discussion within the primary curriculum. In order to illustrate and to evaluate this framework two educational programs were designed to be used in conjunction with a series of lessons to coach the use of 'exploratory talk' in small group work. Evaluation of the first item ...

Contemporary higher education with its large audiences suffers from passivity of students. Enhancing the classroom with a digital backchannel can contribute to establishing and fostering active participation of and collaboration among students in the lecture. Therefore, we conceived the digital backchannel Backstage specifically tailored for the use in large classes. At an early phase of develo...

In this paper, we introduce memory [en]code, a project that evolved through an art+science collaboration. memory [en]code is an interactive tabletop installation that visualizes different concepts of human memory in an interactive and exploratory way. Designed to be installed in a public space, memory [en]code enables people to enter their personal memories and to explore memories entered by ot...

A misspecification testing strategy designed to ensure that the statistical assumptions underlying a system of equations are appropriate is outlined. The system tests take into account information in, and interactions between, all equations in the system and can be used in a wide variety of applications where systems of equations are estimated. The system testing approach is demonstrated by mod...

This paper describes a teleconferencing application that uses real objects to interact with virtual on-screen content. A variety of tangible interaction techniques can be used to load, translate, rotate and scale shared virtual models. In addition, snapshots of real documents can be easily introduced into the system and enlarged using a tangible lens. We describe the teleconferencing interface ...

While a person’s internal state might not be easily inferred through an automatic computer system, within a group, people express themselves through their interaction with others. The group members’ interaction can be then helpful to understand, to certain extent, its members’ affective behavior in any case toward the task at hand. In this context, a Collaborative Virtual Environment for learni...
