“I Don’t Want to Become a Number’’: Examining Different Stakeholder Perspectives on a Video-Based Monitoring System for Senior Care with Inherent Privacy Protection (by Design)
Active and Assisted Living (AAL) technologies aim to enhance the quality of life of older adults and promote successful aging. While video-based AAL solutions offer rich capabilities for better healthcare management in older age, they pose significant privacy risks. To mitigate the risks, we developed a video-based monitoring system that incorporates different privacy-preserving filters. We deployed the system in one assistive technology center and conducted a qualitative study with older adults and other stakeholders involved in care provision. Our study demonstrates diverse users’ perceptions and experiences with video-monitoring technology and offers valuable insights for the system’s further development. The findings unpack the privacy-versus-safety trade-off inherent in video-based technologies and discuss how the privacy-preserving mechanisms within the system mitigate privacy-related concerns. The study also identifies varying stakeholder perspectives towards the system in general and highlights potential avenues for developing video-based monitoring technologies in the AAL context.This work was funded by the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 861091 for the visuAAL project. This publication is based upon work from COST Action GoodBrother—Network on Privacy-Aware Audio- and Video-Based Applications for Active and Assisted Living (CA19121), supported by COST (European Cooperation in Science and Technology)
BUILDING AN EVALUATION FRAMEWORK OF ENVIRONMENTAL INTERPRETATION FOR CHINESE GEOPARKS---CASE STUDY OF YUNTAISHAN WORLD GEOPARK
Environmental interpretation is a key tool for integrated management of tourism, with potential for greater use in managing visitor numbers, behavior and impacts, and enhancing experience. Evaluation is necessary to determine whether interpretation is achieving its goals. It is vital for park managers to know if their management is effective in order to determine what techniques can be used to address a particular problem. The study first introduces the background of Geoparks, and clarifies the definition of environmental interpretation. Next, the study identifies the context that a comprehensive evaluation framework for environmental interpretation in Geoparks is used in order to help Geopark managers to institute the continuous improvement of environmental interpretation. The detailed objectives include: 1.To build an evaluation indicator framework that can be used by Geoparks to evaluate environmental interpretation; 2.To use the evaluation indicator framework to study Yuntaishan World Geopark; 3. To use the data provided by Yuntaishan World Geopark to identify the perceptions of the visitors; 4. To use the data provided by Yuntaishan World Geopark to identify the perceptions of experts and peers
SpeechMirror: A Multimodal Visual Analytics System for Personalized Reflection of Online Public Speaking Effectiveness
As communications are increasingly taking place virtually, the ability to
present well online is becoming an indispensable skill. Online speakers are
facing unique challenges in engaging with remote audiences. However, there has
been a lack of evidence-based analytical systems for people to comprehensively
evaluate online speeches and further discover possibilities for improvement.
This paper introduces SpeechMirror, a visual analytics system facilitating
reflection on a speech based on insights from a collection of online speeches.
The system estimates the impact of different speech techniques on effectiveness
and applies them to a speech to give users awareness of the performance of
speech techniques. A similarity recommendation approach based on speech factors
or script content supports guided exploration to expand knowledge of
presentation evidence and accelerate the discovery of speech delivery
possibilities. SpeechMirror provides intuitive visualizations and interactions
for users to understand speech factors. Among them, SpeechTwin, a novel
multimodal visual summary of speech, supports rapid understanding of critical
speech factors and comparison of different speech samples, and SpeechPlayer
augments the speech video by integrating visualization of the speaker's body
language with interaction, for focused analysis. The system utilizes
visualizations suited to the distinct nature of different speech factors for
user comprehension. The proposed system and visualization techniques were
evaluated with domain experts and amateurs, demonstrating usability for users
with low visualization literacy and its efficacy in assisting users to develop
insights for potential improvement.Comment: Main paper (11 pages, 6 figures) and Supplemental document (11 pages,

Augmenting the field experience: a student-led comparison of techniques and technologies
In this study we report on our experiences of creating and running a student fieldtrip exercise which allowed students to compare a range of approaches to the design of technologies for augmenting landscape scenes. The main study site is around Keswick in the English Lake District, Cumbria, UK, an attractive upland environment popular with tourists and walkers. The aim of the exercise for the students was to assess the effectiveness of various forms of geographic information in augmenting real landscape scenes, as mediated through a range of techniques and technologies. These techniques were: computer-generated acetate overlays showing annotated wireframe views from certain key points; a custom-designed application running on a PDA; a mediascape running on the mScape software on a GPS-enabled mobile phone; Google Earth on a tablet PC; and a head-mounted in-field Virtual Reality system. Each group of students had all five techniques available to them, and were tasked with comparing them in the context of creating a visitor guide to the area centred on the field centre. Here we summarise their findings and reflect upon some of the broader research questions emerging from the project

Introduction to location-based mobile learning
[About the book]
The report follows on from a 2-day workshop funded by the STELLAR Network of Excellence as part of their 2009 Alpine Rendez-Vous workshop series and is edited by Elizabeth Brown with a foreword from Mike Sharples. Contributors have provided examples of innovative and exciting research projects and practical applications for mobile learning in a location-sensitive setting, including the sharing of good practice and the key findings that have resulted from this work. There is also a debate about whether location-based and contextual learning results in shallower learning strategies and a section detailing the future challenges for location-based learning
EXPLORING DIGITAL ETHNOGRAPHY APPLIED TO LANGUAGE LEARNING STUDY: A LITERATURE REVIEW
Abstract
The digital or virtual atmosphere in the education field today begins to spread which includes in the area of language learning. In line with that one, a research design is proposed in a similar context that is Digital Ethnography (DE). The research aims are to reveal and explore the detail of DE and how it is implemented in research. The method used in this study is qualitative, and the data is collected from 10 articles from reputable journals that discuss DE. The collected data were categorized based on the year, title, author, purpose, method result and discussion, and conclusion, afterward they were analyzed and presented descriptively. The findings of this study showed that DE can be applied in various topic particularly in language learning research. The implication of this study DE can be as one of the options as the research design related to language learning in a digital or virtual context.
