Many firms use maintenance reports as a decision support tool. However, reports are often poor quality and tedious to compile. A Conversational User Interface (CUI) could streamline the reporting process by validating the user’s input, eliciting more valuable information, and reducing the time needed. In this paper, we use a Technology Probe to explore the potential of a CUI to create instructional maintenance reports. We conducted a between-groups study (N = 24) in which participants had to replace the inner tube of a bicycle tire. One group documented the procedure using a CUI while replacing the inner tube, whereas the other group compiled a paper report afterward. The CUI was enacted by a researcher according to a set of rules. Our results indicate that using a CUI for maintenance reports saves a significant amount of time, is no more cognitively demanding than writing a report, and results in maintenance reports of higher quality.","PeriodicalId":138046,"journal":{"name":"Proceedings of the 4th Conference on Conversational User Interfaces","volume":"463 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120873437","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}

Algorithms and Attitude towards Conversational User Interfaces: Comparing Chatbots and Voice Assistants","authors":"Sara Irma Parnell, Stefan Klein, Franziska Gaiser","doi":"10.1145/3543829.3544517","DOIUrl":"https://doi.org/10.1145/3543829.3544517","url":null,"abstract":"As conversational user interfaces (CUIs) are increasingly integrated into daily life, ethical and societal concerns about integrated content filtering algorithms emerge. In addressing these concerns, it is essential to know how aware and knowledgeable society is of the algorithms it encounters using CUIs and the extent to which this impacts the attitude towards these technologies. In this survey study, we made a first attempt to measure and compare participants’ algorithm awareness of chatbots and voice assistants. Further, we assessed the effect of algorithm literacy on the attitude towards CUIs and possible interaction effects with technology acceptance. Lastly, we compared previous and future usage purposes for chatbots and voice assistants. We found higher algorithm awareness for voice assistants than for chatbots. No correlation between algorithm literacy and attitude towards either chatbots or voice assistants was found. An additional personal-level factor, technology acceptance, did not affect this relationship. The results show that participants preferred using voice assistants for task completion and social purposes over chatbots, while getting information was equally preferred between chatbots and voice assistants. Considering its societal relevance, we want to encourage more research on algorithmic awareness and understanding in the field of CUI and its cognitive and behavioral effects.","PeriodicalId":138046,"journal":{"name":"Proceedings of the 4th Conference on Conversational User Interfaces","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127077951","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, due to the pace of this growth, the tech industry has had to adapt quickly and vigorously to keep up with demand. Due to this, we currently have limited understanding of the environment of VUI design in industry, including the various multitude of practices and tools that are used. We also have a limited understanding of the barriers VUI designers currently still face. To address such knowledge gaps, we conducted a large-scale online survey to explore the design practices employed by VUI industry designers on-the-job, and the barriers and needs of VUI designers. We found that despite the availability of a wide range of guidelines, textbooks, tools, etc, there are significant gaps in the adoption of these tools within VUI industry design, and that designers rely on their previous experience in developing GUIs when designing VUIs. Based on our survey findings, we provide recommendations for how the HCI community may direct research efforts in developing tools to assist designers in overcoming existing barriers and build usable and adoptable VUIs.","PeriodicalId":138046,"journal":{"name":"Proceedings of the 4th Conference on Conversational User Interfaces","volume":"676 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114085298","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}

When such support is not available, technology can offer a solution. We conducted a participatory design study with the aim of producing content recommendations for a supportive conversational agent (CA) for adolescents. Twenty teens between the ages of 12 to 18 were invited to converse about issues they were experiencing and offer conversational support to each other. Analysis of participants’ conversations revealed that stress was the most frequent problem participants would seek support for. Participant responses to each other's problems offered both cognitive and emotional support, including advice on changing one's behavior, seeking help from others, prioritizing one's wellbeing, and statements of unconditional emotional support, among others. The findings indicate that many of the observed conversational solutions can be programmed in a supportive CA to appeal to a large group of adolescents.","PeriodicalId":138046,"journal":{"name":"Proceedings of the 4th Conference on Conversational User Interfaces","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114014608","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}

A multimodal conversational recommender system (using text and images in particular) aims to replicate this process by eliciting the dynamic preferences of users from their natural-language feedback and updating the visual recommendations so as to satisfy the users’ current needs through multi-turn interactions. However, the impact of positive and negative natural-language feedback on the effectiveness of multimodal conversational recommendation has not yet been fully explored.Since there are no datasets of conversational recommendation with both positive and negative natural-language feedback, the existing research on multimodal conversational recommendation imposed several constraints on the users’ natural-language expressions (i.e. either only describing their preferred attributes as positive feedback or rejecting the undesired recommendations without any natural-language critiques) to simplify the multimodal conversational recommendation task. To further explore the multimodal conversational recommendation with positive and negative natural-language feedback, we investigate the effectiveness of the recent multimodal conversational recommendation models for effectively incorporating the users’ preferences over time from both positively and negatively natural-language oriented feedback corresponding to the visual recommendations. We also propose an approach to generate both positive and negative natural-language critiques about the recommendations within an existing user simulator. Following previous work, we train and evaluate the two existing conversational recommendation models by using the user simulator with positive and negative feedback as a surrogate for real human users. Extensive experiments conducted on a well-known fashion dataset demonstrate that positive natural-language feedback is more informative relating to the users’ preferences in comparison to negative natural-language feedback.","PeriodicalId":138046,"journal":{"name":"Proceedings of the 4th Conference on Conversational User Interfaces","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128117920","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 two studies that investigate how the formality of a chatbot’s conversational style can affect the likelihood of users engaging with and disclosing sensitive information to a chatbot. In our first study, we show that the domain and sensitivity of the information being requested impact users’ preferred conversational style. Specifically, when users were asked to disclose sensitive health information, they perceived a formal style as more competent and appropriate. In our second study, we investigate the health domain further by analysing the quality of user utterances as users talk to a chatbot about their dental flossing. We found that users who do not floss every day gave higher quality responses when talking to a formal chatbot. These findings can help designers choose a chatbot’s language formality for their given use case.","PeriodicalId":138046,"journal":{"name":"Proceedings of the 4th Conference on Conversational User Interfaces","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116331903","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 introduce a conversational system which connects a chatbot with a mainstream messaging service in a multi-user scenario. While there are already numerous options for single-user bots, ready-to-use systems for multiple users and group chats are scarce. This work thus aims to get insight into how such a group chatbot should behave during a multi-turn conversation. For this, we implemented and evaluated four different moderation strategies in an everyday use-case: the planning and negotiation of a joint appointment. In our subsequent user study with 40 participants, we investigated how the different strategies were perceived and what influence they had on the acceptance, usability and efficiency of the system. Our evaluation results show that users’ perceptions of innovation and inventiveness of the bot were influenced by the moderation strategies.","PeriodicalId":138046,"journal":{"name":"Proceedings of the 4th Conference on Conversational User Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131095699","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}

To explore this question in a multi-faceted manner, designers, engineers, philosophers as separate focus groups were given a design fiction probe— a story of a chatbot’s disappearance from a person’s life. Though articulated in discipline-specific ways, participants expressed similar concerns and hopes: 1) caring for a machine could teach people to emotionally care for themselves and others, 2) the boundary between human and non-human emotions may become blurred when people project their own emotions onto AI, e.g., a bot’s ”breakdown” as one’s own, and 3) people may then intertwine their identities with AI through emotions. We consider ethical ramifications of socially constructed emotions between humans and conversational agents.","PeriodicalId":138046,"journal":{"name":"Proceedings of the 4th Conference on Conversational User Interfaces","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133261732","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}

Despite this diversity, the opportunities of designing chatbots for more complex decision-making tasks remain largely underexplored. Bearing this in mind leads us to ask: How can chatbots be embedded into software tools used for complex decision-making and designed to scaffold and probe human cognition? The goal of our research was to explore possible uses of such “probing bots”. The domain we examined was stock investment where many complex decisions need to be made. In our study, different types of investors interacted with a prototype, which we called “ProberBot”, and subsequently took part in in-depth interviews. They generally found our ProberBot was effective at supporting their thinking but when this is desirable depends on the type of task and activity. We discuss these and other findings as well as design considerations for developing ProberBots for similar types of decision-making tasks.","PeriodicalId":138046,"journal":{"name":"Proceedings of the 4th Conference on Conversational User Interfaces","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116449827","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}
