Deictic gestures are gestures we make during communication to point at objects or persons. Indicative acts of directing-to guide the addressee to an object, while placing-for acts place an object for the addressee’s attention. Commonly used presentation software tools, such as PowerPoint and Keynote, offer ample support for placing-for gestures, e.g. slide transitions, progressive disclosure of list items and animations. Such presentation tools, however, do not generally offer adequate support for the directing-to indicative act (i.e. pointing gestures). In this paper we argue the value of presenting deictic gestures to a remote audience. Our research approach is threefold: identify indicative acts that are naturally produced by presenters; design tangible gestures for multi-touch surfaces that replicate the intent of those indicative acts; and design a set of graphical effects for remote viewing that best represent these indicative acts for the audience.

The current study investigated how individual differences among children affect the added value of social robots for teaching second language (L2) vocabulary to young children. Specifically, we investigated the moderating role of three individual child characteristics deemed relevant for language learning: first language (L1) vocabulary knowledge, phonological memory, and selective attention. We expected children low in these abilities to particularly benefit from being assisted by a robot in a vocabulary training. An L2 English vocabulary training intervention consisting of seven sessions was administered to 193 monolingual Dutch five-year-old children over a three- to four-week period. Children were randomly assigned to one of three experimental conditions: 1) a tablet only, 2) a tablet and a robot that used deictic (pointing) gestures (the no-iconic-gestures condition), or 3) a tablet and a robot that used both deictic and iconic gestures (i.e., gestures depicting the target word; the iconic-gestures condition). There also was a control condition in which children did not receive a vocabulary training, but played dancing games with the robot. L2 word knowledge was measured directly after the training and two to four weeks later. In these post-tests, children in the experimental conditions outperformed children in the control condition on word knowledge, but there were no differences between the three experimental conditions. Several moderation effects were found. The robot's presence particularly benefited children with larger L1 vocabularies or poorer phonological memory, while children with smaller L1 vocabularies or better phonological memory performed better in the tablet-only condition. Children with larger L1 vocabularies and better phonological memory performed better in the no-iconic-gestures condition than in the iconic-gestures condition, while children with better selective attention performed better in the iconic-gestures condition than the no-iconic-gestures condition. Together, the results showed that the effects of the robot and its gestures differ across children, which should be taken into account when designing and evaluating robot-assisted L2 teaching interventions.

From the article : "In this paper the implications of different research approaches and methods are illustrated by using two projects of the authors. Both projects take place in the same context: exploring participatory innovation within Small-to-Medium sized Enterprizes (SMEs). The main aspects coming forward when comparing the research characteristics of both projects are the importance of time and momentum, the structural set up of the project, people or participants and the abilities of the people involved. The research goal and the background of the researcher are main determinants for the chosen research methods. We hope with this paper to make researchers aware of the implications of the research methods and approach on the results of the project."

In this paper we explore the influence of the physical and social environment (the design space) son the formation of shared understanding in multidisciplinary design teams. We concentrate on the creative design meeting as a microenvironment for studying processes of design communication. Our applied research context entails the design of mixed physical–digital interactive systems supporting design meetings. Informed by theories of embodiment that have recently gained interest in cognitive science, we focus on the role of interactive “traces,” representational artifacts both created and used by participants as scaffolds for creating shared understanding. Our research through design approach resulted in two prototypes that form two concrete proposals of how the environment may scaffold shared understanding in design meetings. In several user studies we observed users working with our systems in natural contexts. Our analysis reveals how an ensemble of ongoing social as well as physical interactions, scaffolded by the interactive environment, grounds the formation of shared understanding in teams. We discuss implications for designing collaborative tools and for design communication theory in general.

This article provides a description of the emergence of the Spanish ‘Occupy’ movement, Democracia real ya. The aim is to analyse the innovative discursive features of this movement and to connect this analysis to what we consider the innovative potential of the critical sciences. The movement is the result of a spontaneous uprising that appeared on the main squares of Madrid and Barcelona on 15 May 2011 and then spread to other Spanish cities. This date gave it its name: 15M. While the struggle for democracy in Spain is certainly not new, the 15M group shows a series of innovative features. These include the emphasis on peaceful struggle and the imaginary of a new democracy or worldview, transmitted through innovative placards and slogans designed by Spanish citizens. We consider these innovative not only due to their creativity, but also because of their use as a form of civil action. Our argument is that these placards both functioned as a sign of protest and, in combination with the demonstrations and the general dynamics of 15M, helped to reframe the population’s understanding of the crisis and rearticulate the identity of the citizens from victims to agents. In order to analyse the multimodal character of this struggle, we developed an interdisciplinary methodology, which combines socio-cognitive approaches that consider ideological proposals as socio-cognitive constructs (i.e. the notion of narrative or cognitive frame), and Critical Discourse Analysis (CDA) in the analysis of discourses related to processes of social imagination and transformation. The socio-constructivist perspective is used to consider these discourses in relation to their actors, particular contexts and actions. The use of CDA, which included a careful rhetoric analysis, helped to analyse the process of deconstruction, transformation and reconstruction that 15M uses to maintain its struggle. The narrative analysis and the discursive theoretical concept of articulation helped to methodologically show aspects of the process of change alluded to above. This change was both in terms of cognition and in the modification of identity that turned a large part of the Spanish population from victims to indignados and to the neologism indignadanos, which is a composition of indignado and ciudadano (citizen).

Through a correspondence between two scholars, this paper explores and critiques various ways in which scholars working in ethnography and cultural analysis frame and construct their methodology and object of study. Through the close reading of theoretical accounts of methodology in ethnography and cultural analysis, we examine how these accounts construct the relationship between the scholar and her object of study.We read these scholarly practices as protocols, referring to the ways in which accounts of methodology may be understood as rules/guidelines by which scholars in these fields conduct research. Protocol etymologically refers to protos (first) and kolla (glue). Through the figure of the protocol, we delineate how scholars in ethnography and cultural analysis themselves become implicated in giving accounts of their research methodologies. Somatechnics presents a thoroughly multi-disciplinary scholarship on the body, providing a space for research that critically engages with the ethico-political implications of a wide range of practices and techniques. The term ‘somatechnics’ indicates an approach to corporeality which considers it as always already bound up with a variety of technologies, techniques and technics, thus enabling an examination of the lived experiences engendered within a given context, and the effects that technologies, technés and techniques have on embodiment, subjectivity and sociality.
