Despite the potential of such verbalization patterns, they were uncovered with native English speakers. As most people who speak English are non-native speakers, it is important to investigate whether similar patterns exist in non-native English speakers’ TA verbalizations. As a first step to answer this question, we conducted think-aloud usability testing with Chinese non-native English speakers and native English speakers using three common TA protocols. We compared their verbalizations and UX problems that they encountered to understand the effects of language and TA protocols. Our findings show that both language groups had similar amounts and proportions of verbalization categories, encountered similar problems, and had similar verbalization patterns that indicate UX problems. Furthermore, TA protocols did not significantly affect the correlations between verbalizations and problems. Based on the findings, we present three design implications for UX practitioners and the design of AI-assisted analysis tools.","PeriodicalId":321721,"journal":{"name":"The Ninth International Symposium of Chinese CHI","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127183172","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}

In this paper we investigated two research questions related to Finger-Fitts law: (1) Should Finger-Fitts law use nominal target width W or effect target width We to model MT? and (2) should Finger-Fitts law use a pre-defined value (denoted by σa) or a free parameter (denoted by c) to represent the absolute ambiguity caused by finger touch? Our investigation on two touch pointing datasets showed that there are cases where using nominal width has stronger model fitness, and also cases where using effective width is better. Regarding the representation of finger ambiguity, using a free parameter c to represent the ambiguity of finger touch always leads to stronger model fitness than using the pre-defined σa, after controlling for overfitting. It indicates that viewing the finger ambiguity as an empirically determined parameter has more flexibility to capture the ambiguity of finger touch involved in the study. Overall, our research advances the understanding on how to model Finger touch input with Finger-Fitts law.","PeriodicalId":321721,"journal":{"name":"The Ninth International Symposium of Chinese CHI","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114499312","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}

Initially, 2098 papers were identified, of which 16 papers were included in the final analysis. These 16 papers were published in 15 various conference proceedings or journals between 2010 and 2021, and mainly focused on tracking eating moment and promoting healthy food intake. Our findings showed that four types of digital tools for healthy eating promotion were commonly used, including mobile applications, wearables, service, and multicomponent (i.e., a combination between mobile apps and wearables). Moreover, we found that current digital tools made small using a range of existing working infrastructures. Future design research could focus on personalized, interactive, and playful digital tools in human-computer interaction field with behavior change techniques and user-centered approaches to promote healthy eating behaviors in daily work routines.","PeriodicalId":321721,"journal":{"name":"The Ninth International Symposium of Chinese CHI","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134178937","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 firstly carried out an auto-ethnography as well as a probe-based co-design study to explore dedicated social mechanisms for promoting healthy hydration habits. This led to the conceptualization of Co-Drink that focuses on technology-enabled social interactions between individuals with intimate relationships to stimulate their water intake behaviors. Co-Drink was implemented as a pair of smart water bottles with ambient light. It also associated with an app to facilitate a coaching mode and a co-learning mode for persuading health behavior change. The prototypes of Co-Drink were evaluated in a Wizard-of-Oz study with three dyads of college students. Results showed its benefits for hydration health promotion and applicability for daily life use, due to the embedded social mechanisms and the ambient displays integrated with the water bottle.

Persuading college students to build healthy and active communications with their parents can be a valuable subject. This paper presents an exploratory design study, investigating a tangible interactive product to help parents and children easily build shared communication experiences remotely. Firstly, we conducted an auto-ethnographical study to explore the design opportunities for improving off-site parent-teenager relationship. In return, we design LUNOST, a pair of metaphorical devices that enables emoji exchange, voice messaging and weather sharing between teenagers and parents over a distance through several tangible interactions, without using any digital tools. Based on the prototypes of LUNOST, we carried out a preliminary user test with 14 college students and 10 parents of them to examine the feasibility user experience of our design concept. Our quantitative findings suggested that LUNOST was experienced significantly useful, in terms of its usability (p=0.003), aesthetics (p=0.001), and perceived motivations (p=0.002). Qualitative results indicated that our design could be useful to remind youngsters to keep in touch with their parents and enable parents to subtly learn the status of their children.

In this study, the common spatial layout in mixed reality is divided into three basic types: vertical layout, horizontal layout and distributed layout. This study discusses the user experience of the above three interaction modes in the above three layout modes. The results show that gaze and pinch interaction provides users with the most efficient, relaxed and enjoyable choice interaction. Head and pinch interaction has no obvious advantages.

However, in terms of interactive maps are limited. Rich interaction, such as issuing a complex query: “Which route has more greenery for my evening run?” is currently impossible to process for most Geographic Information Systems (GIS). To enable such rich interaction, data in GIS needs to be extended with high-level semantic annotations. Such annotations, due to their intrinsic semantic nature, can currently only be supplied by humans, who might moreover also need to have some expert knowledge about GIS in order to produce useful annotations. Given the cognitive resources required, the number of annotations to be made, and the tediousness of the task, there is a need to design systems that can support experts in completing such annotation tasks. We report on a study comparing two alternative systems for performing GIS annotations, a Conversational User Interface (CUI), designed for the purpose of this study, and a Web interface with NN GIS, which reflects the current state-of-the-art used by experts. We find that CUIs can indeed help to improve the accuracy and efficiency of the annotations. We conclude the paper with some tentative design principles for annotation systems coupled to complex user interfaces.","PeriodicalId":321721,"journal":{"name":"The Ninth International Symposium of Chinese CHI","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114714623","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}
