However, previous studies have frequently demonstrated that these models are attackable through slight modifications of their inputs, so-called adversarial attacks. Hence, researchers proposed investigating examples of these attacks with explainable artificial intelligence to understand them better. In this line, we developed an expert tool to explore adversarial attacks and defenses against them. To demonstrate the capabilities of our visualization tool, we worked with the publicly available CIFAR-10 dataset and generated one-pixel attacks. After that, we conducted an online evaluation with 16 experts. We found that our tool is usable and practical, providing evidence that it can support understanding, explaining, and preventing adversarial examples.","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":"128876575","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}

Hence, an opportunity exist to explore asynchronous situations, in which collaborative actions take place at different times. Despite the physical distance and different time zones, remote experts can generate MR-instructions to assist with emerging problems, suggesting to on-site collaborators where to act, and what to do. This work explored three distinct notification methods for such scenarios: C1 - visual cue; C2 - audio cue; C3 - tactile cue, aiming to comprehend which one captures the attention of on-site team-members easily. A user study with 12 participants was conducted to evaluate these conditions during an asynchronous scenario of remote maintenance. We report participants insights, suggesting tactile cues represent the predominant condition given the scenario context.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"78 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":"114260746","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 work describes a user study with 12 participants, aimed at comparing the use of three distinct conditions: C1 - Head-Mounted Display (HMD), C2 - Handheld Device (HHD) and C3 - Paper manual during a set of realistic training tasks, selected based on a collaboration with partners from the industry sector.

Conversational Agents, or chatbots, rely on advances in AI and are increasingly investigated in the context of digital mental health care. Given how they are end-user-facing and interactive communication tools, the user engagement felt when interacting with the bots is a critical consideration. In this work, we examine the effects of chatbot personalities on the experienced user engagement with the bot. We employed personalities that rely on the Big-5 Personality Theory. Among other findings, our quantitative results indicate that a highly conscientious chatbot is likely to foster the highest user engagement. Our qualitative and content analysis also reveals desired and undesired personality features for future mental health chatbots. We discuss our findings in light of digital mental health and propose novel research directions.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"61 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":"134032214","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}

One interesting approach to get back such tangibility in digital systems is using pen and touch interactions. Pen and touch interactions presented in tablet computers are natural and efficient. Pen additional data, like pressure and tilt, can be used for novel interactions. However, most of the previous research that combines pen and touch inputs discards such additional inputs and limits the interactions to Cartesian coordinates and is applied to data visualization or static media contexts. In this work, we have implemented a prototype running on a tablet that aims to facilitate video browsing through the combination of pinch gestures and pen tilt. It aims to provide more natural and tangible interactions to control dynamic media and, at the same time, promote novel interactions using familiar inputs.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"25 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":"125224085","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 way, diverse populations can be reached and studies using virtual reality can be conducted in settings characterized by high ecologic validity. In this study (N=21) we investigate challenges participants face as they are required to set up and calibrate a virtual reality system in their home without assistance from experimenters. This allowed us to identify key reasons why participants struggle with this task. Our findings suggest that providing illustrative instructions and additional assistance on request can notably increase the success rate of setting up a VR environment for participating in a remote study. Interestingly, we also find that it is harder to recruit participants who do not have prior VR experience to participate in remote VR studies. We derive suggestions on how to support this task based on our findings.","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":"129111324","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 there seem to be few examples of designs for non-competitive play which allow participants to take very different roles. Bringing together elements of playing with dance, communication, and drawing, we present the Move It Like Picasso platform. This facilitates a collaboration between a player trying to physically trace flickering lines from an animation which are unpredictably triggered by the second player’s bodily movements. We offer this as an example of how combining simple digital technologies and everyday physical materials may offer a route to rich social play experiences that might simultaneously appeal to a wide range of tastes.","PeriodicalId":310437,"journal":{"name":"Proceedings of the 21st International Conference on Mobile and Ubiquitous Multimedia","volume":"12 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":"127554419","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, most of the research done uses a stationary setup. This work proposes HeatGoggles, a wearable gadget detecting touch input on arbitrary surfaces using thermal imaging.
