However, avatars with different topologies than the human form require control schemes and interfaces that effectively translate between user and avatar. In this position paper, we discuss the concept of ”non-anthropomorphic designs” that are inhuman in not just appearance, but in topology and/or motion. We examine current implementations of real and virtual non-anthropomorphic hands (NAHs), finding that existing NAHs generally rely on one-to-one or reductionist control strategies that limit their possible forms. We discuss the structure of a functional NAH system and design considerations for each component, including metrics for evaluating NAH system performance. The terminology and design considerations presented here support future research on NAHs in virtual and physical reality, as well as virtual and physical tool design, the body schema, and novel control interfaces and mappings.","PeriodicalId":123301,"journal":{"name":"CHI Conference on Human Factors in Computing Systems Extended Abstracts","volume":"537 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132797453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the phenomenon is relevant to HCI, and signifies important developments for future interactive products. To better understand the NFT phenomenon, and to inform future HCI research and design, we investigated the stakeholders in the NFT ecosystem and relations between them. Based on open data we mined from the social news website Hacker News, we contribute the first data-backed model of stakeholders in the NFT ecosystem. The model reveals a nuanced account of the outlooks of creators, owners, and technologists; identifies investment firms and auction houses as arbiters of knowledge and value; and presents implications for future research.","PeriodicalId":123301,"journal":{"name":"CHI Conference on Human Factors in Computing Systems Extended Abstracts","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133209294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a user study to evaluate the influence of six different types of video content (including nature, cooking, and a new food video genre known as mukbang) on people’s flavor perceptions in terms of taste sensations, liking, and emotions while eating plain white rice. Our findings revealed that the participants’ flavor perceptions are augmented based on different video content, indicating significant differences in their perceived taste sensations (e.g., increased perception of salty and spicy sensations). Furthermore, potential future implications are revealed to promote digital commensality and healthier eating habits.","PeriodicalId":123301,"journal":{"name":"CHI Conference on Human Factors in Computing Systems Extended Abstracts","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133430250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the cognition and perception theory of glyphs is largely unknown for many tasks including “categorization”. Categorization tasks are common in everyday life from sorting objects to a doctor diagnosing a patient’s disease. However it is unknown how glyph designs, specifically anthropomorphic human-like representations which in prior visualization research have demonstrated improved information recall, affect accuracy in a categorization task. To better understand how people comprehend and perceive glyphs for categorization, including anthropomorphic representations, we conducted a crowdsourced experiment to evaluate whether more human-like glyphs would lead to higher categorization accuracy. Contrary to our hypothesis, we found evidence that subjects are more accurate with a less anthropomorphic glyph. A posthoc analysis also reveals that anthropomorphic glyphs introduce biases due to their anatomically salient features. Based on these results we propose design guidelines for glyphs used in categorization tasks.

For this, we developed a digital thimble that users wear in their index finger. The thimble uses an optical sensor to track the finger and a pressure sensor to detect touch and contact force. In a week-long in-the-wild pilot study, Shapeshifter yielded on average 11 wpm on flat surfaces (e.g., a desk) and 9 wpm on the lap when sitting down, and 8 wpm on the palm and back of the hand when standing up in text composition tasks.

They can look at images of the product, read reviews, make comparisons with other products, do research online, read expert reviews, and more. Voice shopping (purchasing items via a Voice assistant such as Amazon Alexa or Google Assistant) is different. Voice introduces novel challenges as the communication channel is limited in terms of the amount of information people can and are willing to absorb. Because of this, the system should choose the single most effective nugget of information to help the customer, and present the information succinctly. In this paper we report on a within-subject user study (N = 24), in which we employed three template-based methods that use information from customer reviews, product attributes and search relevance signals to generate helpful supporting information. Our results suggest that: (1) supporting information from customer reviews significantly improves participants perception of system effectiveness (helping them make good decisions); (2) supporting information based on search relevance signals improves user perception of system transparency (providing insight into how the system works). We discuss the implications of our findings for providing supporting information for customers shopping by Voice.","PeriodicalId":123301,"journal":{"name":"CHI Conference on Human Factors in Computing Systems Extended Abstracts","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134511964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, online learning and co-working experience are far from satisfactory, which is partly due to lacking engagement and instantaneous visual interaction that we used to have when conducting those activities offline. Thus, my goal is to propose methods helping us better adapt to rapidly changing visual contexts. In the formative research, I created dynamic peripheral vision blocking glasses, and its experimental result indicates that wearing such glasses helped its users suffer fewer motion sickness symptoms while accessing fast-moving surrounding scenery in a VR environment.

Though commercial CUI developments continue to rapidly advance, our scholarly dialogue on ethics of CUIs is underwhelming. The CUI community has implicitly been concerned with ethics, yet making it central to the growing body of work thus far has not been adequately done. Since ethics is a far-reaching topic, perspectives from philosophy, design, and engineering domains are integral to our CUI research community. For instance, philosophical traditions, e.g., deontology or virtue ethics, can guide ethical concepts that are relevant for CUIs, e.g., autonomy or trust. The practice of design through approaches like value sensitive design can inform how CUIs should be developed. Ethics comes into play with technical contributions, e.g., privacy-preserving data sharing between conversational systems. By considering such multidisciplinary angles, we come to a special topic of interest that ties together philosophy, design, and engineering: conversational disclosure, e.g., sharing personal information, transparency, e.g., as how to transparently convey relevant information in a conversational manner, and vulnerability of diverse user groups that should be taken into consideration.","PeriodicalId":123301,"journal":{"name":"CHI Conference on Human Factors in Computing Systems Extended Abstracts","volume":"344 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123102723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We explore considerations for the design of authentication for visitors evolving around, e.g., the visitors themselves as well as the environment and concrete mechanisms. Moreover, we suggest a concrete idea: security questions to authenticate visitors in smart homes. In an interview study (N = 24), we found that owners and visitors appreciated the low effort and would adapt our approach. We conclude with future research directions that we hope will spark further discussions around the design of authentication for smart homes, considering visitors and owners alike.","PeriodicalId":123301,"journal":{"name":"CHI Conference on Human Factors in Computing Systems Extended Abstracts","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131680649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
