This paper presents instead a design, implementation, and in-the-wild Wizard of Oz evaluation of a backpack with shape-changing accessory which output is directed to others approaching the wearer from behind. Qualitative findings from six participants suggest that there is potential in shape-changing accessory for keeping social distance in public context, however, the social acceptability issues caused by noisy motors and inclusiveness of the design limit the willingness to wear it. Even though the study was inspired by the Covid-19, other non-pandemic use cases for personal space respecting wearables are discussed also for users with special needs.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121222016","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, they are less effective at extracting qualitative data. Due to response fatigue when answering open-ended questions, the quality of responses may be poor, and participants can skip answering individual questions, or drop out from the survey entirely, potentially introducing bias. To address these challenges, we developed a prototype tool that enables a test moderator to initiate a chat intervention with a participant at any point during the completion of an online survey. Through this approach, participants can be prompted to return to complete unanswered questions or provide clarification to given answers. A functional prototype system has been implemented and, as future work, will be evaluated with a variety of content and question types.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116647571","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}

Interviewees sometimes become nervous about the interview because interviewees themselves do not know their assessed score. This study investigates the relationship between the communication skill (CS) and the self-efficacy level (SE) of interviewees through multimodal modeling. We also clarify the difference between effective features in the prediction of CS and SE labels. For this purpose, we collect a novel multimodal job interview data corpus by using a job interview agent system where users experience the interview using a virtual reality head-mounted display (VR-HMD). The data corpus includes annotations of CS by third-party experts and SE annotations by the interviewees. The data corpus also includes various kinds of multimodal data, including audio, biological (i.e., physiological), gaze, and language data. We present two types of regression models, linear regression and sequential-based regression models, to predict CS, SE, and the gap (GA) between skill and self-efficacy. Finally, we report that the model with acoustic, gaze, and linguistic features has the best regression accuracy in CS prediction (correlation coefficient r = 0.637). Furthermore, the regression model with biological features achieves the best accuracy in SE prediction (r = 0.330).","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132033999","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, our initial work and that of others show that most of these technologies focus on data, not the user. Based on interviews, development of mood boards, and the creation of a research product, we propose an alternative approach to self-tracking: re-humanising self-tracking technologies. Our work shows that feelings play an important role with data, that data are temporal, and associated with work and utility. We interpret four design criteria, which are applied in the creation of Frankie: a human-centred tracking device which records both quantitative (number of activities) and qualitative (perceived weight of the activity and spoken reflections) data to foster self-reflection. Through this design case we add to the discussion on re-imagining self-tracking technologies to go beyond data-centric artefacts.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129136332","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 contrast to existing methods, such as screen-printing, ECPlotter allows for quick early prototyping with minimal human intervention and makes the process more accessible since the fabrication is automated. Our software pipeline enables designers to convert graphics directly into an instruction set that can be interpreted by the printer which includes automatic heat and UV curing passes after ink depositing. Finally, we demonstrate its capabilities by printing on a variety of substrates.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130144082","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}

Specifically, it examines the effects of the level autobiographical memory is induced through photos on smartphone attachment and how this relationship is influenced according to the emotions induced through these photos. An experiment was conducted on 17 individuals 22-37 years old. Each participant was asked to select a photo from their smartphone that caused the strongest emotions and was asked to write a memory induced by the photo in about 200 characters. The participant then measured their emotions for the selected photo and responded to a questionnaire about memory and mobile attachment. As a result, it was confirmed that valence regulates the relationship between autobiographical memory and smartphone attachment. In particular, it has been shown that when emotions are unpleasant, they induce strong smartphone attachment with higher levels of autobiographical memory.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"291 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115946266","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}

The majority of smartphone users sometimes feel distracted by their mobile devices and have experienced regretful smartphone use. The downsides of smartphone use have been widely explored by the literature. What is missing, however, is a suggestion of alternative activities users would like to perform instead of using their smartphone. We therefore conducted an online survey with N = 67 participants exploring users preferred activities alternative to regretful smartphone use for different time-frames. Our results show that usage sessions shorter than ten minutes are less prone to inducing a feeling of regret. Users’ concrete suggestions range from relaxation and self-care activities (10 to 20 minutes) to social and outdoor activities (more than 20 minutes) with a trend towards leisure activities rather than work-related ones. We finally provide impulses how to promote these activities through technology.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131362433","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 introduce HeadsUp, a mobile app designed to warn the user of imminent collisions with solid obstacles. HeadsUp runs on unmodified commodity smartphones without additional hardware and uses active ultrasound sensing based on the Doppler effect. We contribute an analysis of the ultrasound audio characteristics of six different smartphone models to verify the feasibility of our approach across vendors and device classes, and a description of two implementation variants of our signal processing pipeline. We evaluate our system both in a lab environment and under real-world conditions, and we conclude that HeadsUp can effectively work at a range of up to 3 meters, even though overall performance is heavily dependent on both the individual user and the environment characteristics.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132873725","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}
