Inbodied interaction 102: exploring neuro-physio pathways for self-tuning
No full textIn Inbodied Interaction 101, we considered the Physiology and Anatomy of the body via three associated interactions that reflect an inbodied state: 1. inbodied adaptation in response to the in5 and C4 over Time and Context in order to maintain 2. homeostasis via 3. metabolism. We called this adaptation process "tuning."In 102 we build on this foundation to consider the physiology tuning. In particular we will look at a series of inbodied interactions: the neuro-endocrine system interaction with the organ systems that cue adaptive responses from genetic signals to fat metabolism; the autonomic nervous system and the limbic system's interactions that affect volitional/non-volitional interaction. We will introduce the components of the brainstem, basal nuclei and cerebellum that support interoception around self-Tuning. Within this framing, we will look at the strengths and limits of non-invasive measures of these processes (eg, HRV, EEG, blood oxygen saturation, qualitative responses). Outcomes will familiarity with how we function as inbodied complex systems, with worked examples of how the physiology of tuning can be translated into interactive designs to support health, wellbeing, performance in new ways.</p
Comparing heart rate variability biofeedback and simple paced breathing to inform the design of guided breathing technologies
No full textIntroduction: A goal of inbodied interaction is to explore how tools can be designed to provide external interactions that support our internal processes. One process that often suffers from our external interactions with modern computing technology is our breathing. Because of the ergonomics and low-grade-but-frequent stress associated with computer work, many people adopt a short, shallow breathing pattern that is known to have a negative effect on other parts of our physiology. Breathing guides are tools that help people match their breathing patterns to an external (most often visual) cue to practice healthy breathing exercises.However, there are two leading protocols for how breathing cues are offered by breathing guides used in non-clinical settings: simple paced breathing (SPB) and Heart Rate Variability Biofeedback (HRV-b). Although these protocols have separately been demonstrated to be effective, they differ substantially in their complexity and design. Paced breathing is a simpler protocol where a user is asked to match their breathing pattern with a cue paced at a predetermined rate and is simple enough to be completed as a secondary task during other activities. HRV-b, on the other hand, provides adaptive, real-time guidance derived from heart rate variability, a physiological signal that can be sensed through a wearable device. Although the benefits of these two protocols have been well established in clinical contexts, designers of guided breathing technology have little information about whether one is better than the other for non-clinical use. Methods: To address this important gap in knowledge, we conducted the first comparative study of these two leading protocols in the context of end-user applications. In our N=28 between-subject design, participants were trained in either SPB or HRV-b and then completed a 10-minute session following their training protocol. Breathing rates and heart rate variability scores were recorded and compared between groups. Results and discussion: Our findings indicate that the exercises did not significantly differ in their immediate outcomes – both resulted in significantly slower breathing rates than their baseline and both provided similar relative increases in HRV. Therefore, there were no observed differences in the acute physiological effects when using either SPB or HRV-b. Our paper contributes new findings suggesting that simple paced breathing – a straightforward, intuitive, and easy-to-design breathing exercise – provides the same immediate benefits as HRV-b, but without its added design complexities.</p
The body as starting point: Applying inside body knowledge for inbodied design
No full textInbodied design is an emerging area in HCI that focuses on using knowledge of the body's internal systems and processes to better inform em-bodied and circum-bodied design spaces. The current challenge in developing an inbodied approach to HCI research/design is domain expertise: accessing sufficient and appropriate information about how the body itself works and how the body's different systems interact dynamically. In this workshop, we review and build on last year's introduction to inbodied foundations, focusing on applying inbodied knowledge to design challenges to explore (1) the foundational pillars of the inbodied design approach, and (2) how inbodied knowledge can affect / alter our understanding of em-bodied and circum-bodied design challenges and better inform design decisions. Our aim with this hands-on and cross-domain workshop is for HCI researchers to create innovative designs taking the body as a starting poin
Inbodied Interaction 102: Understanding the Selection and Application of Non-invasive Neuro-physio Measurements for Inbodied Interaction Design
No full textAs a means to validate the effects of interaction designs, particularly those involving physiological processes, like: breathing in mindfulness; heartrate in exertion games, and blood flow to the brain for cognitive load assessments, HCI researchers are increasingly turning to body-based signals as signals to quantify effects and guide design decisions. These design decisions can be informed by Inbodied Interaction principles of aligning knowledge of how the body performs optimally (physiologically, neurologically) with our designs. The purpose of this course is to present new-to-HCI neuro-physiological measures including peripheral awareness, deep HRV, and new pre-cortical assessments to open new design opportunities. Students will leave the course with this set of new assessments, as well as practical worked examples of how to choose and apply which measures as best suited for a particular design and evaluation context
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
