Multimodal Data Analysis of Dyadic Interactions for an Automated Feedback System Supporting Parent Implementation of Pivotal Response Treatment

abstract: Parents fulfill a pivotal role in early childhood development of social and communication skills. In children with autism, the development of these skills can be delayed. Applied behavioral analysis (ABA) techniques have been created to aid in skill acquisition. Among these, pivotal response treatment (PRT) has been empirically shown to foster improvements. Research into PRT implementation has also shown that parents can be trained to be effective interventionists for their children. The current difficulty in PRT training is how to disseminate training to parents who need it, and how to support and motivate practitioners after training. Evaluation of the parents’ fidelity to implementation is often undertaken using video probes that depict the dyadic interaction occurring between the parent and the child during PRT sessions. These videos are time consuming for clinicians to process, and often result in only minimal feedback for the parents. Current trends in technology could be utilized to alleviate the manual cost of extracting data from the videos, affording greater opportunities for providing clinician created feedback as well as automated assessments. The naturalistic context of the video probes along with the dependence on ubiquitous recording devices creates a difficult scenario for classification tasks. The domain of the PRT video probes can be expected to have high levels of both aleatory and epistemic uncertainty. Addressing these challenges requires examination of the multimodal data along with implementation and evaluation of classification algorithms. This is explored through the use of a new dataset of PRT videos. The relationship between the parent and the clinician is important. The clinician can provide support and help build self-efficacy in addition to providing knowledge and modeling of treatment procedures. Facilitating this relationship along with automated feedback not only provides the opportunity to present expert feedback to the parent, but also allows the clinician to aid in personalizing the classification models. By utilizing a human-in-the-loop framework, clinicians can aid in addressing the uncertainty in the classification models by providing additional labeled samples. This will allow the system to improve classification and provides a person-centered approach to extracting multimodal data from PRT video probes.Dissertation/ThesisDoctoral Dissertation Computer Science 201

Infrastructuring for cultural commons

In this doctoral dissertation, I inquire into the ways in which Participatory Design (PD) and digital design endeavors can contribute to wider public access to, and use of, digital cultural heritage. I advocate for an approach according to which digital cultural heritage is arranged and understood as cultural commons, and for more collaborative modes of social care for and governance of the commons. In addition to the empirically grounded findings and proposals contained in six individual research articles, I develop a theoretical framework that combines scholarship on Information Infrastructures, Commons and PD. Against this framework I interrogate how the information infrastructures and conditions that surround digital cultural heritage can be active in constructing and contributing to cultural commons. While doing this, I draw attention to the gap that exists between on the one hand official institutional digital cultural heritage collections, systems and practices, and on the other hand the digital platforms and practices through which everyday people create, curate and share digital cultural works. In order to understand how to critically and productively bridge this gap, I present insights gained from conducting three design research cases that engage both cultural heritage institutions and everyday media users. Building upon this empirical work, and latching on to scholarship on the notion of infrastructuring, I propose four infrastructuring strategies for cultural commons: probing and building upon the installed base, stimulating and simulating design and use through gateways, producing and pooling shared resources, and, lastly, fostering and shaping a commons culture that supports commoning. In exploring these strategies, I map the territory between commons and infrastructuring, and connect these notions to the PD tradition. I do so to sketch the design principles for a design orientation, commons design. I assert that these principles can be useful for advancing PD, and can inform future initiatives, aid in identifying infrastructural challenges, and in finding and confirming an orientation to participatory design activities. Drawing on my practical design work, I discuss requirements for professional designers operating on commons frameworks and with collective action. By doing this, my dissertation not only breaks new theoretical ground through advancing theoretical considerations relevant to contemporary design research, especially the field of PD, but also contributes practical implications useful for professional digital media design practice, especially for designers working in the fields of digital culture and cultural heritage

Pre-conference proceedings of the 3rd IFIP TC 13.6 HWID working conference

The committees under IFIP include the Technical Committee TC13 on Human – Computer Interaction within which the work of this volume has been conducted. TC 13 on Human-Computer Interaction has as its aim to encourage theoretical and empirical human science research to promote the design and evaluation of human-oriented ICT. Within TC 13 there are different Working Groups concerned with different aspects of Human-Computer Interaction. The flagship event of TC13 is the bi-annual international conference called INTERACT at which both invited and contributed papers are presented. Contributed papers are rigorously refereed and the rejection rate is high. Publications arising from these TC13 events are published as conference proceedings such as the INTERACT proceedings or as collections of selected and edited papers from working conferences and workshops. See http://www.ifip.org/ for aims and scopes of TC13 and its associated Working Group

P5 eHealth: An Agenda for the Health Technologies of the Future

This open access volume focuses on the development of a P5 eHealth, or better, a methodological resource for developing the health technologies of the future, based on patients’ personal characteristics and needs as the fundamental guidelines for design. It provides practical guidelines and evidence based examples on how to design, implement, use and elevate new technologies for healthcare to support the management of incurable, chronic conditions. The volume further discusses the criticalities of eHealth, why it is difficult to employ eHealth from an organizational point of view or why patients do not always accept the technology, and how eHealth interventions can be improved in the future. By dealing with the state-of-the-art in eHealth technologies, this volume is of great interest to researchers in the field of physical and mental healthcare, psychologists, stakeholders and policymakers as well as technology developers working in the healthcare sector
