Understanding the relationship between in-car agent’s embodiments and information with different criticality
No full textAs the infotainment system in cars has advanced, drivers now receive a wide range of information from agents while driving. However, despite the diversity of roles and types of information, the embodiment of the agent delivering the information remains unified. Therefore, we sought to understand the needs for different types of information and their correlation with an embodiment. To achieve this, we created four embodiment prototypes within a car model ‘Sound without Visual Embodiment’, ‘Sound and (Abstract) Graphic Embodiment’, ‘Sound and (Characterized) Graphic Embodiment’, ‘Sound and (Characterized) Graphic and (Characterized) Physical Embodiment’ and conducted a user experience evaluation with 12 participants. Based on the type of information, we identified two types of needs which are attention level and urgency of delivery. Additionally, we determined the effects of warning, recommendation, and reference information for each embodiment. This paper aims to enhance the understanding of the diverse roles and effects of agent embodiment for in-car UX and to design agents\u27 embodiments that meet the needs of information delivery
The Voice Experience Inventory (VOXI): Validating a consensus-driven instrument for measuring user impressions of computer voice
No full textVoice interaction has entered daily life. Yet, the measurement of voice user experience (voice UX) remains underdeveloped. We took a consensus-based approach to the creation of a new instrument grounded in the work of voice UX researchers. For this, we conducted a systemic review of the literature from ACM, IEEE, and Web of Science (N = 49) to gather a corpus of instruments, measures, and methodological perspectives. We then carried out two validation studies on a range of computer voices, showing through exploratory (N = 100) and confirmatory factor analyses (N = 150) that five underlying factors unify the consensus-derived measures. We offer the 24-item Voice Experience Inventory (VOXI) alongside three comprehensive frameworks on key independent and dependent variables and their relationships, anchored to the material that guided our instrument development process. This work represents a timely and community-centred path towards rigorous and standardized measurement of voice UX.
Virfie: Enhancing Remote Togetherness with User-Created Scenarios for Virtual Group Selfie
No full textTaking group selfies via video conferencing has become a popular way of developing a close, interpersonal relationship with people in remote situations. However, existing systems are not suitable for building social bonds due to their limitations such as rigid grid-based layout, information overloading, and difficult eye contact to name a few. Based on design opportunities and user needs from a participatory ideation session, we developed Virfie, a novel web-based video conferencing platform that (1) allows dynamic compositions of users, background, and overlaid graphics; (2) enables embodied social interaction via collective challenges; and (3) fosters social narratives with multi-scene scenarios. Based on the feedback from a user study we confirm that Virfie strengthens social bonds and the feeling of remote togetherness
(The) effect of in-car agent embodiment on delivery of information with different criticality
No full text학위논문(석사) - 한국과학기술원 : 산업디자인학과, 2024.2,[vi, 86 p. :]자동차의 인포테인먼트 기술이 발전하면서 운전자는 운전 중에 다양하고 많은 정보들을 차량 에이전트로부터 받고 있다. 그러나 다양한 정보의 유형에도 불구하고, 에이전트의 실체화는 하나로 통일되어 있다. 포커스 그룹 인터뷰를 통해 운전 중 전달받는 정보들을 반드시 반응해야 되는 정보, 선택 또는 비선택이 가능한 정보 그리고 무시해도 되는 정보로 분류할 수 있음을 발견했다. 그리고 사용자가 주목하길 원하는 정도에 따라 6가지로 세부 분류할 수 있다는 것을 알아냈다. 정보의 유형에 따른 운전자의 니즈를 이해하고, 실체화 특성이 충족시켜줄 수 있는 부분을 파악하고자 하였다. 이를 위해, 자동차 모형 안에서 3가지(소리와 추상적인 그래픽, 소리와 캐릭터 그래픽, 소리와 캐릭터 그래픽과 물리적인 형태)의 프로토타입을 만들고, 20명의 참가자의 사용 경험을 조사하였다. 이후에 참가자들은 에이전트의 물리성, 캐릭터성 및 움직임을 조절하여 정보 9개를 전달하는 에이전트를 디자인 하였다. 디자인 결과를 통해, 정보 유형마다 다른 운전자의 요구와 실체화 특성이 가진 경험적 효과 사이의 관계를 파악하였다. 본 논문은 차량 경험 향상을 위해 에이전트의 실체화 특성이 갖고 있는 경험적 효과에 대한 이해를 돕고, 정보를 전달하는 에이전트를 디자인하는데 활용할 수 있을 것이다.한국과학기술원 :산업디자인학과
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
