Sourcing on the internet: Examining the relations among different phases of online inquiry

2021

This study examined students’ engagement in sourcing throughout online inquiry, that is, when they specified the information need, formulated search queries, evaluated online texts, and composed a written product. Participants were 167 upper secondary school students. Students completed an online inquiry task in a restricted online environment that utilized authentic online texts. Students’ prior topic knowledge and reading fluency was measured and controlled for in the analysis. The results showed that students engaged in sourcing even in the earliest phases of online inquiry. A sequential regression analysis indicated that the more frequently students engaged in sourcing in specifying the…

Expectations for supporting student engagement with learning analytics : an academic path perspective

2021

There has been a growing interest in higher education to explore how learning analytics (LA) could be used to support student engagement. Providing actionable feedback with LA for students is an emerging area of research. Previous studies have commonly focused on course-level aspects of supporting engagement with LA, but students' perspectives have received limited attention. This study analyzed pre-service teachers’ needs and expectations for LA to support student engagement on the academic path level, which means observing the continuum of study periods and academic years. Qualitative content analysis was conducted for video-recorded student small-group conversations to analyze in-depth h…

Can't simply roll it out: Evaluating a real-world virtual reality intervention to reduce driving under the influence.

2020

Driving under the influence (DUI) increases the risk of crashes. Emerging technologies, such as virtual reality (VR), represent potentially powerful and attractive tools for the prevention of risky behaviours, such as DUI. Therefore, they are embraced in prevention efforts with VR interventions primed to grow in popularity in near future. However, little is known about the actual effectiveness of such DUI-targeting VR interventions. To help fill the knowledge gap, this study explored the effects of one VR intervention as delivered in the real world. Using pre and post test design, including an intervention group (n = 98) and a control group (n = 39), the intervention evaluation examined you…

Composing only by thought: Novel application of the P300 brain-computer interface.

2017

The P300 event-related potential is a well-known pattern in the electroencephalogram (EEG). This kind of brain signal is used for many different brain-computer interface (BCI) applications, e.g., spellers, environmental controllers, web browsers, or for painting. In recent times, BCI systems are mature enough to leave the laboratories to be used by the end-users, namely severely disabled people. Therefore, new challenges arise and the systems should be implemented and evaluated according to user-centered design (USD) guidelines. We developed and implemented a new system that utilizes the P300 pattern to compose music. Our Brain Composing system consists of three parts: the EEG acquisition d…

In vivo versus augmented reality exposure in the treatment of small animal phobia: A randomized controlled trial

2016

Although in vivo exposure is the treatment of choice for specific phobias, some acceptability problems have been associated with it. Virtual Reality exposure has been shown to be as effective as in vivo exposure, and it is widely accepted for the treatment of specific phobias, but only preliminary data are available in the literature about the efficacy of Augmented Reality. The purpose of the present study was to examine the efficacy and acceptance of two treatment conditions for specific phobias in which the exposure component was applied in different ways: In vivo exposure (N = 31) versus an Augmented Reality system (N = 32) in a randomized controlled trial. “One-session treatment” guidel…

Phase Coherence in Conceptual Spaces for Conversational Agents

2010

This chapter attempts to enhance the traditional chatbots with associative/intuitive capabilities. According to these considerations, it tries to create a conversational agent model that takes into consideration, aside from the traditional rule - based dialogue mechanism, also some sort of intuitive reasoning ability. The aim is in attempting to overcome the rigid pattern - matching rules, proposing a "phase coherence" paradigm into a semantic space. With this locution the chapter intend that the vectors representing the elements of the dialogue are coherent with the context. The chapter trust that this intuitive - associative capability can be obtained using the LSA methodology. The repres…

A Posture Sequence Learning System for an Anthropomorphic Robotic Hand

2003

The paper presents a cognitive architecture for posture learning of an anthropomorphic robotic hand. Our approach is aimed to allow the robotic system to perform complex perceptual operations, to interact with an human user and to integrate the perceptions by a cognitive representation of the scene and the observed actions. The anthropomorphic robotic hand imitates the gestures acquired by the vision system in order to learn meaningful movements, to build its knowledge by different conceptual spaces and to perform complex interaction with the human operator.

Postcards and Supasigns : Extending Integrationist Theory Through the Creation of Interactive Digital Artworks

2007

Integrationism is a post-structuralist theory of language and communication. The theory has been applied to a groundbreaking analysis of writing as a form of communication where writing is teased apart from speech and realigned with spatial configurations in general. Although it has many practical applications, this view can be extremely difficult to comprehend when expressed as a very specific form of writing, that is, as written words on paper. A solution to this problem is offered by the creative interaction design of two digital artworks, Postcard From Tunis and Postcards From Writing. The works are interactive multimedia pieces that creatively express the integrationist theory of writi…
