A report on participatory workshops for the design of adaptive collaborative learning

This “work-in-progress” paper discusses the process of conducting participatory workshops during the design of an adaptive, collaborative learning system. We outline our methods for exploring group interaction, collaboration, and learning in an iterative series workshops. We conclude with a discussion of how the results of these workshops have influenced our ongoing work in designing an adaptive system for family groups in the museum

Situating approaches to museum guides for families and groups

In this paper, we analyze the current state of museum guide technologies and applications in order to develop an analytical foundation for our future research in an adaptive museum guide for families. We have focused our analysis on three critical areas of interest in considering group and social interaction in museums: tangibility, the role of tangible user interfaces; interaction, visit types and visit flows; adaptivity, user modeling approaches

Situating approaches to interactive museum guides

This paper examines the current state of museum guide technologies and applications in order to develop an analytical foundation for future research on an adaptive museum guide for families. The analysis focuses on three critical areas of interest in considering group and social interaction in museums: tangibility the role of tangible user interfaces; interaction visit types and visit flows; and adaptivity user modeling approaches. It concludes with a discussion of four interrelated trajectories for interactive museum guide research including embodied interaction, gameplay, transparent and opaque interaction and the role of personal digital assistants

Kurio: A museum guide for families

We discuss three design strategies for improving the quality of social interaction and learning with interactive museum guides: 1) embodied interaction; 2) game-learning; 3) a hybrid system. We used these strategies in our prototype Kurio, which is aimed at supporting families visiting museums. The results of our evaluation show positive implications of implementing the design strategies: closing the social gap, naturalizing technology, and supporting exploration and discovery in learning

Three Modern Roles for Logic in AI

We consider three modern roles for logic in artificial intelligence, which are based on the theory of tractable Boolean circuits: (1) logic as a basis for computation, (2) logic for learning from a combination of data and knowledge, and (3) logic for reasoning about the behavior of machine learning systems.Comment: To be published in PODS 202

Diagnostic Delay Is Associated with Complicated Disease and Growth Impairment in Paediatric Crohn\u27s Disease

Background: Paediatric data on the association between diagnostic delay and inflammatory bowel disease [IBD] complications are lacking. We aimed to determine the effect of diagnostic delay on stricturing/fistulising complications, surgery, and growth impairment in a large paediatric cohort, and to identify predictors of diagnostic delay. Methods: We conducted a national, prospective, multicentre IBD inception cohort study including 1399 children. Diagnostic delay was defined as time from symptom onset to diagnosis \u3e75th percentile. Multivariable proportional hazards [PH] regression was used to examine the association between diagnostic delay and stricturing/fistulising complications and surgery, and multivariable linear regression to examine the association between diagnostic delay and growth. Predictors of diagnostic delay were identified using Cox PH regression. Results: Overall (64% Crohn\u27s disease [CD]; 36% ulcerative colitis/IBD unclassified [UC/IBD-U]; 57% male]), median time to diagnosis was 4.2 (interquartile range [IQR] 2.0-9.2) months. For the overall cohort, diagnostic delay was \u3e9.2 months; in CD, \u3e10.8 months and in UC/IBD-U, \u3e6.6 months. In CD, diagnostic delay was associated with a 2.5-fold higher rate of strictures/internal fistulae (hazard ratio [HR] 2.53, 95% confidence interval [CI] 1.41-4.56). Every additional month of diagnostic delay was associated with a decrease in height-for-age z-score of 0.013 standard deviations [95% CI 0.005-0.021]. Associations persisted after adjusting for disease location and therapy. No independent association was observed between diagnostic delay and surgery in CD or UC/IBD-U. Diagnostic delay was more common in CD, particularly small bowel CD. Abdominal pain, including isolated abdominal pain in CD, was associated with diagnostic delay. Conclusions: Diagnostic delay represents a risk factor for stricturing/internal fistulising complications and growth impairment in paediatric CD

Design intentions and outcomes in museums

This study explores the value of constructivist theory in the field of interaction design in museums by investigating the relationship of constructivist design intentions to their outcomes. As the design of technologies has shifted from instrumental aspects of interactive systems to the design of experience, there has become an increasing need to develop frameworks and evaluation techniques grounded in theory to support this change. Current approaches to understanding the user experience are underdeveloped and this study of intentions and outcomes aims to address this shortcoming through an exploratory multiple-case study approach. Museums were selected as a context to investigate these relationships since designers often take a constructivist approach in the development of interactive technology towards the design of experiences. The findings of this study point to an emerging constructivist framework by providing a series of themes, guidelines and evaluation techniques based on constructivist principles

Bridging designers\u27 intentions to outcomes with constructivism

This exploratory study investigates the value of constructivist theory for the field of interaction design. In this paper we explore how designer intentions and outcomes can be expressed in constructivist terms, and how constructivism can describe the relationship of design intentions to outcomes. This study’s findings point to the potential of an emerging constructivist framework. The authors present the findings of two case studies of designer intentions and outcomes from two museum design projects. The paper presents themes drawn from the analysis that include designing for personal experience, play, and social interaction
