In this paper we explore a new direction for pedagogical computer characters, which we believe will maximize students’ learning gains and enjoyment. To the traditional scenario where students interact primarily with a single coach or tutor character on-screen, we introduce the addition of both a social, animate colearner, and the student’s own avatar… (More)
Although certain forms of epilepsy have long been suspected to be inherited, heterogeneity has made it difficult to find the genes responsible for any subtypes. We found that families ascertained through patients with juvenile myoclonic epilepsy show linkage with the BF and HLA loci on human chromosome 6. There is some evidence that the locus may be outside… (More)
When cats make slow scanning head movements, intersaccadic counterrotary eye movements are driven by the vestibulo-ocular reflex, but reset or forward saccades are not directly affected by vestibular afference. When the movements are rapid (approximately 200 deg./sec), large (greater than 40 degrees), and executed in single step shifts gaze (whether in the… (More)
Scientific practices increasingly incorporate sensors for data capture, information visualization for data analysis, and low-cost mobile devices for fieldbased inquiries incorporating open web standards. While a broad range of design approaches for developing technology-enhanced learning has been used by researchers and practitioners for the last 15 years,… (More)
This paper presents the implementation of Tigrito, an affective computer character. We outline how Tigrito can be used to study chidren’s sense of engagement and relationship with virtual toys in different modes of interaction.
I.-INTRODUCTION: Most of the research within the field of interactive characters has concentrated on generating guidelines, or models, for believable individual variability among characters, often based on psychological personality models (such as Nass, Isbister and Lee, 2000), or biological behaviors (for example, see Blumberg, 1994). In contrast, we… (More)
Single-unit activity was recorded with stereotaxically guided microelectrodes in the central thalamus of five alert cats. The animals were studied with the head either fixed or free to move in a horizontal plane. They were trained to make eye and/or head movements toward discrete visual targets presented on a screen. Unit activity was analyzed in relation… (More)
This paper presents a short overview of Tigrito, a highaffect virtual toy where children observe and interact with emotive improvisational characters, which we built to study the sense of engagement and suspension of disbelief across different modes of interaction, and the affective relationship between children and a virtual toy.
Designers today use a variety of artifacts — both physical and digital — in the course of documenting their work. Physical and digital media have significantly different affordances and organizing metaphors: most notably, paper remains the preferable medium for sketching but lacks the sharing affordances of digital media. Augmented paper interactions… (More)
