Features of spatial context and non-verbal communication in students’ vlogs in their english learning

Vlog is a simple video which a person faces a camera and addresses a public viewership briefly, informally, and more or less intimately. In this study, there are two aspects in the vlog that will be examined, namely aspects of the spatial context and nonverbal communication in the vlog. Spatial context is how an item is in relation to its environment. While nonverbal language is expressing meaning or feeling without words such as gesture, body language, eye contact, facial expression, space, picture and painting. The aims of this research is to identify features and functions of spatial context and nonverbal communication in students’ vlogs in fourth semester students’ of English Language Education Department of State Islamic University of Sunan Ampel Surabaya. This study is included as a qualitative design. Since there is no manipulation in explaining the phenomena in this study, this method is considered appropriate to be applied in this study. Selecting relevant data collection techniques and tools is considered important in a study in addition to determining the appropriate method. Meanwhile, to obtain the data, the researcher used three techniques, namely observation, questionnaire and documentation. The finding showed that there are two types of spatial context on the vlogs such as space relation with their elements which functions for define which objects should be represented in an area, and how they should be represented. While group relations with its members which is states that many geographical objects become more meaningful by being part of a group of other objects than by being alone. Meanwhile, for nonverbal communication, there are two features of nonverbal communication in the five videos, namely hand movements and facial expressions. The researcher found four types of functions that can be found in nonverbal communication within the five vlogs, namely accent, repetition, complement, and substitution

Understanding Context to Capture when Reconstructing Meaningful Spaces for Remote Instruction and Connecting in XR

Recent technological advances are enabling HCI researchers to explore interaction possibilities for remote XR collaboration using high-fidelity reconstructions of physical activity spaces. However, creating these reconstructions often lacks user involvement with an overt focus on capturing sensory context that does not necessarily augment an informal social experience. This work seeks to understand social context that can be important for reconstruction to enable XR applications for informal instructional scenarios. Our study involved the evaluation of an XR remote guidance prototype by 8 intergenerational groups of closely related gardeners using reconstructions of personally meaningful spaces in their gardens. Our findings contextualize physical objects and areas with various motivations related to gardening and detail perceptions of XR that might affect the use of reconstructions for remote interaction. We discuss implications for user involvement to create reconstructions that better translate real-world experience, encourage reflection, incorporate privacy considerations, and preserve shared experiences with XR as a medium for informal intergenerational activities.Comment: 26 pages, 5 figures, 4 table

RealitySketch: Embedding Responsive Graphics and Visualizations in AR through Dynamic Sketching

We present RealitySketch, an augmented reality interface for sketching interactive graphics and visualizations. In recent years, an increasing number of AR sketching tools enable users to draw and embed sketches in the real world. However, with the current tools, sketched contents are inherently static, floating in mid air without responding to the real world. This paper introduces a new way to embed dynamic and responsive graphics in the real world. In RealitySketch, the user draws graphical elements on a mobile AR screen and binds them with physical objects in real-time and improvisational ways, so that the sketched elements dynamically move with the corresponding physical motion. The user can also quickly visualize and analyze real-world phenomena through responsive graph plots or interactive visualizations. This paper contributes to a set of interaction techniques that enable capturing, parameterizing, and visualizing real-world motion without pre-defined programs and configurations. Finally, we demonstrate our tool with several application scenarios, including physics education, sports training, and in-situ tangible interfaces.Comment: UIST 202

The Educational Experience of Virtual Reality: An Archaeological Case Study of the Maya Site, Vista Alegre

Archaeological visualization has a long history within the discipline, relying on technological advancements to aid in recording, interpreting, and educating about sites and projects. Though computer graphics have been used as archaeological visualizations for decades, hardware advancements have begun to allow for broader consumer use of Virtual and Augmented Reality platforms in homes, schools, and museums. This thesis explores the applications of Virtual and Augmented Reality platforms for archaeological visualization, specifically in the area of public education. To this end, a 3D model and virtual experience of the Maya site of Vista Alegre in Mexico are created, methodologically explained, and examined to relate history, theory, and the goals of utilizing this medium within the archaeological discipline while expanding on the ethical requirements and empirical methods of praxis. In all, this technology both produces tangible, quantifiable, and accurate data and makes these data more accessible to the general public. Image from Proskouriakoff (1970[1946]

It has many potential applications in education, medicine, and engineering, among other fields. This book explores these potential uses, presenting case studies and investigations of AR for vocational training, emergency response, interior design, architecture, and much more

Reconstructing the Present Through Kinesthetic History: An Investigation into Modes of Preserving, Transmitting, and Restaging Contemporary Dance

Methods of dance preservation have evolved alongside conceptual themes that have framed dance’s historical narrative. The tradition of written dance notation developed in accordance with notions that prioritized logocentricity, and placed historical legitimacy on tangible artifacts and irrefutable archives; whereas the technical revolution of the late twentieth century saw dance preservation practices shift to embrace film and video documentation because they provided more accessible, and more convenient records. Since the 1970s video recordings have generally been considered to provide authentic visual representations of dance works, and the tradition of score writing has begun to wane. However, scholarly criticism has unveiled both philosophical and practical challenges posed by these two modes of documentation, thus illuminating a gap between theories of embodiment and the practice of dance preservation. In alignment with contemporary discourse, which legitimizes the body as a site of generating and storing knowledge, this dissertation suggests ‘kinesthetic history’ as a valid mode of dance preservation. Operating as a counterpart to oral history, and borrowing theoretical concepts from contemporary historiography, existential phenomenology and ethnography, the term ‘kinesthetic history’ suggests a mode of corporeal inscription and transmission that relies on the reciprocal interaction of bodies in space. The use of ‘kinesthetic history’ as a methodological approach to the preservation, translation, and reconstruction of movement material reflects the elements of fluidity, plurality and subjectivity that are often characteristic of contemporary choreographic practices. This theory is interrogated through a case study, which explores the ways in which both a written and digitized score, video recordings, and the ‘kinesthetic history’ of an original cast member operated as modes of transmission in a 2013 restaging of William Forsythe’s One Flat Thing, reproduced (2000) at The Juilliard School. Conclusions drawn from the case study challenge the traditional notions of reconstruction and restaging and suggest ‘regeneration’ as an alternative term to describe the process of preserving and transmitting contemporary dance works

Treatment effects of stimulant medication in young boys with fragile X syndrome

Fragile X syndrome (FXS) is the most common inherited form of intellectual disability and is caused by a CGG repeat expansion at Xq27.3 on the FMR1 gene. The majority of young boys with FXS display poor attention and hyperactivity that is disproportionate to their cognitive disability, and approximately 70% meet diagnostic criteria for attention-deficit/hyperactivity disorder. Psychopharmacology is employed with 82% of young males 5–17 years of age, with stimulant medication as the most common medication prescribed. This study evaluated the effects of stimulant medication on the academic performance, attention, motor activity, and psychophysiological arousal of boys with FXS, as well as the concordance of effects within individuals. Participants in this study included 12 boys with FXS who were treated with stimulants. Participants completed videotaped academic testing on two consecutive days and were randomly assigned to be off stimulants for 1 day and on stimulants the other day. On each day, multiple measures including academic performance, behavior regulation, and psychophysiological arousal were collected. Approximately 75% of participants performed better on attention and academic measures, and 70% showed improved physiological regulation while on stimulant medication. A high degree of concordance among measures was found. Lower intelligence quotient (IQ), but not age, correlated with greater improvements in in-seat behavior. IQ and age did not relate to on-task behaviors. The frequency and magnitude of response to stimulant medication in boys with FXS is higher than those reported for most children with non-specific intellectual disabilities and autism spectrum disorder

Contextualized Monitoring in the Marine Environment

Marine mammal monitoring has seen improvements in the last few decades with advances made to both the monitoring hardware and post-processing computation methods. The addition of tag-based hydrophones, Fastloc GPS units, and an ever-increasing array of IMU sensors, coupled with the use of energetics proxies such as Overall Dynamic Body Acceleration (ODBA), has led to new insights into marine mammal swimming behavior that would not be possible using traditional secondary-observer methods. However, these advances have primarily been focused on and implemented in wild animal tracking, with less attention paid to the managed environment. This is a particularly important gap, as the cooperative nature of managed animals allows for research on swimming kinematics and energetics behavior with an intricacy that is difficult to achieve in the wild. While proxy-based methods are useful for relative inter-or-intra-animal comparisons, they are not robust enough for absolute energetics estimates for the animals, which can limit our understanding of their metabolic patterns. Proxies such as ODBA are based on filtered on-animal IMU data, and measure the aggregate high-pass acceleration as an estimate for the magnitude of the animal’s activity level at a given point in time. Depending on its body structure and locomotive gait, tag placement on the animal and the specific filtering techniques used can significantly impact the results. Any relation made to energetics is then strictly a mapping: a relation that may apply well to an individual or group under specific experimental conditions, but is not generalizable. To address this gap, this dissertation presents new tag-based hardware and data processing methods for persistently estimating cetacean swimming kinematics and energetics, which are functional in both managed and wild settings. Unfortunately, localization techniques for managed environments have not been thoroughly explored, so a new animal tracking method is required to spatially contextualize information on swimming behavior. State-of-the-art wild cetacean localization operates via sparse GPS updates upon animal surfacings, and can be paired with biologging-tag-based odometry for a continuous track. Such an approach is hindered by the structure and scale of managed environments: GPS suffers from increased error near and within buildings, and current odometry methods are insufficiently precise for habitat scales where locations of interest might be separated by meters, rather than kilometers (such as in the wild). There is then a need for a tracking method that uses an alternate source of absolute animal locations that can achieve the high precision necessary for meaningful results given the spatial scale. To this end, this dissertation presents a novel animal localization framework, based on tracking and sensor filtering techniques from the field of robotics that have been tailored for use in this setting. Overall, this research targets two main gaps: 1) the lack of persistent, absolute estimates of animal swimming energetics and kinematics, and 2) the lack of a robust, precise localization method for managed cetaceans. To address these gaps, the hardware and animal tracking methods developed to enable the rest of the dissertation are first defined. Next, a physics-based approach to directly monitor cetacean swimming energetics is both presented and implemented to study animal propulsion patterns under varying effort conditions. Finally, a high-fidelity 3D monitoring framework is introduced for tracking institutionally-managed cetaceans, and is applied alongside the energetics estimation method to provide a first look at the potential of spatially-contextualized animal monitoring.PHDRoboticsUniversity of Michigan, Horace H.
