This SIG is a forum to advance an integrated approach to multi-modal Natural User Interfaces. Up until now the research and design of NUI interfaces for various modalities (speech, touch, gesture) has proceeded independently. We propose having an integrated discussion with both academics and practitioners to stimulate the exchange of knowledge about the various modalities and how they might be fruitfully combined, andidentifying key areas of future research and design that make the case for multi-modal NUIs. The goal is to not only create a vision of synthetic applications of NUI by connecting researchers but to also discuss ways to make the vision a reality.
Although many visualization techniques have been shown to be pedagogically effective, they are still not widely adopted. The reasons include: lack of suitable methods of automatic-generation of visualizations, lack of integration among visualizations, and lack of integration with basic integrated development environment (IDE) support. To effectively use visualizations when developing code, it is useful to automatically generate multiple synchronized views without leaving the IDE. The jGRASP IDE provides object viewers that automatically generate dynamic, state-based visualizations of objects and primitive variables in Java. Such seamless integration of a lightweight IDE with a set of pedagogically effective software visualizations is unique and is currently unavailable in any other environment. Multiple instructors have reported positive anecdotal evidence of their usefulness. We conducted formal, repeatable experiments to investigate the effect of these viewers for singly linked lists on student performance and we found a statistically significant improvement over traditional methods of visual debugging that use break-points.
This workshop will identify best practices for longitudinal research through an in-depth exploration of methods and metrics for collecting and analyzing user data over time. This is the fourth event in an ongoing effort by the organizers to enhance our current body of knowledge about longitudinal research.
The interest in longitudinal studies of users' experiences and behaviors with interactive products is mounting, while recent methodological advances have enabled new ways to elicit as well as process longitudinal data. With this workshop we want to establish a forum for the exchange of knowledge and discussion on novel theories, methods and experiences gained through case studies of longitudinal HCI research. This is an effort towards the collection of best practices for an edited book publication.
The jGRASP lightweight IDE has been extended to provide object viewers that automatically generate dynamic, state-based visualizations of data structures in Java. These viewers provide multiple synchronized visualizations of data structures as the user steps through the source code in either debug or workbench mode. This tight integration in a lightweight IDE provides a unique and promising environment for learning data structures. Initial classroom use has demonstrated the object viewers' potential as an aid to students who are learning to write and modify classes representing data structures.Recently completed controlled experiments with CS2 students indicate that these viewers can have a significant positive impact on student performance.
This special interest group probes potential problems between HCI researchers and the practitioners who are consumers of research, to explore the extent of the problems and propose possible solutions. It will start with the results of the CHI 2010 workshop on the same topic, articulating factors that may render some of the research literature inaccessible or irrelevant to practitioners. When should HCI researchers be concerned about the relevance of their work to practitioners? How should practitioners communicate their needs for research? Participants will discuss these topics and others that both groups can use to help bridge the gap between research and practice in HCI.
jGRASP has three integrated approaches for interacting with its dynamic viewers for data structures: debugger, workbench, and text-based interactions that allow individual Java statements and expressions to be executed/evaluated. These approaches can be used together to provide a complementary set of interactions with the dynamic viewers. Data structure identification and rendering were tested by examining examples from 20 data structure textbooks. Controlled experiments with CS2 students indicate that the viewers can have a significant positive impact on student performance. The overall result is a flexible environment for interacting with effective dynamic data structure visualizations generated by a robust structure identifier.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
