Abstract

In this paper, we provide an overview of our attempts to harness data physicalizations as pedagogical tools for enhancing the understanding of visual channels. We first elaborate the research goals that we have crafted for the physicalization prototype, shedding light on the key principles that guided our design choices. Then we detail the materials and datasets we employed for nine channels on our physicalization prototype. A preliminary pilot study is followed to validate its effectiveness. In the end, we present our upcoming research initiatives, including a comparative study for assessing the usability of the physicalization system. In general, the main purpose of our work is to stimulate a wider engagement among visualization educators and researchers, encouraging them to delve into the potentialities of data physicalization as an innovative addition to contemporary teaching methodologies., Comment: 2 pages, 1 figure, IEEE VIS 2023 Poster

Abstract

This article explores the evaluation method for the language communication proficiency of AI-driven robots engaging in interactive communication with children. The utilization of AI-driven robots in children's everyday communication is swiftly advancing, underscoring the importance of evaluating these robots'language communication skills. Based on 11 Chinese families' interviews and thematic analysis of the comment text from shopping websites, a framework is introduced in the article to assess five key dimensions of child-robot language communication: interactivity, specificity, development, sociality, and safety. We draw on the concept of "children's agency", viewing children as active participants in shaping society and cultural life alongside adults. Therefore, this article places particular emphasis on collecting data related to children. Whether through survey interviews or direct interactive experiments, we treat children as an independent object for data collection. The study involved empirical research following the mentioned framework, which involved capturing interaction videos in natural conversation settings among children from 6 families. Analysis was performed on quantitative data obtained from video recordings, alongside questionnaires and interviews carried out by parents acting as participants or observers. We found that the presence or absence of parents during children's interactions with robots can impact the evaluation of robots'language communication abilities. Ultimately, this article proposes an enhanced comprehensive evaluation framework incorporating insights from parents and children, supported by empirical evidence and inter-rater consistency assessments, showcasing the scheme's efficacy., Comment: 7 pages, CHI 2024 The Second Workshop on Child-Centred AI

Abstract

Multiple intersecting situational tasks in the field of aviation often cause air traffic controllers to face issues pertaining to interruption and task switching. To investigate the impact of task interruption on the situation awareness of air traffic controllers, two experiments were conducted. Experiment 1, which focused on 44 new graduates preparing to work in the field of air traffic control, revealed that task interruption reduced the participants' levels of situation awareness. Experiment 2, which focused on 80 new air traffic control graduates, employed a 2 (primary task modality: visual, auditory) × 2 (interruption modality: visual, auditory) between-subjects design and revealed that the negative effect of task interruption on situation awareness was moderated by task modality. Interruptions that occur in the same modality as the primary task were shown to result in greater decreases than were cross modal interruptions. Visual interruption led to a greater decrease in situation awareness than did auditory interruption, and interruption of the visual task also caused a greater decrease in situation awareness than did interruption of the auditory task. These findings might be valuable in attempts to enhance situation awareness among air traffic controllers by providing insights into the design of human‒computer interactions in the context of an air traffic control automation system.

36. Data governance for smart cities in China: the case of Shenzhen

Author

Abstract

Establishing an appropriate system for governing various data is a critical challenge in developing smart cities. In China, with its distinctive institutional characteristics, it is not yet well investigated what kinds of data governance mechanisms are introduced, how data are collected, shared, and used, and how potential risks concerning data security and privacy are addressed. This paper conducts an exploratory study of the case of smart city development in Shenzhen and examines critical opportunities and challenges in data governance. A centralized approach led by the government has been emphasized in data governance, with its focus evolving from addressing the fragmentation of government data to fostering the integration of various kinds of data in society. Open data platforms have been developed through close cooperation between government and technology enterprises. Regulations have been introduced to protect data security and privacy and facilitate the exchange and use of data for innovation. On the other hand, stakeholders are not sufficiently incentivized to provide accurate information. The value of data is not appropriately recognized or measured, discouraging the sharing of data to facilitate the use of data. Citizens are not well-informed about what kinds of data are collected and how these data are used. Institutional mechanisms have not yet been established to ensure that the data collected from citizens are properly handled by the public authorities. It is crucial to encourage citizens’ engagement in data governance to fully implement the people-centered approach to smart city development. © 2023 The Author(s).

Abstract

We report Cu, Fe, N‐doped carbon nanotubes, (Cu,Fe)−N−CNT, as electrocatalysts for the oxygen reduction reaction (ORR) in acidic media. (Cu,Fe)−N−CNT was prepared using a silica coating method in pyrolysis to minimize the formation of carbon‐coated metal oxide or carbide nanoparticles, which are known to be inactive for the H2O2 reduction. (Cu,Fe)−N−CNT shows a turnover frequency of 0.66 e− site−1 s−1 at +0.8 V vs. RHE and H2O2 yields of <1 % for the ORR with a utilization factor of active sites of 82 %. Kinetic analysis reveals that 4e− transfer rates for (Cu,Fe)−N−CNT are higher than those of a monometallic counterpart of Fe−N−CNT. In situ X‐ray absorption spectroscopy enables us to determine redox potentials: E°'(FeIII/FeII)=0.65 V vs. RHE and E°'(CuII/CuI)=0.45 V for (Cu,Fe)−N−CNT, and E°'(FeIII/FeII)=0.65 V for Fe−N−CNT. These results indicate that bimetallic doping into carbon nanotubes gives the effect on kinetic parameters but not on thermodynamic ones. In other words, there is no direct electronic interactions between the Cu and Fe active sites for (Cu,Fe)‐N‐CNT because such interactions should modulate their redox potentials.
