For visitors in an urban setting, translating abstract map symbols into comprehensible information can be a challenging task due to the level of abstraction and the disconnect between flat displays and spatial information. We address this question by combining a tangible user interface (created with 3D-printed buildings) and dynamic spatial information. To explore these concepts, we designed and fabricated the Tangible Map to serve as an interactive centerpiece within the MIT campus. Through application of user-centered design principles, we demonstrate strategies for managing user attention across beyond-field-of-view displays.","PeriodicalId":437505,"journal":{"name":"Proceedings of the 6th ACM International Symposium on Pervasive Displays","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133630859","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 question was how to use the media facade to communicate a broad urban issue in a friendly, site-specific way. Exploring the theme of Belo Horizonte's public transport, the participants developed an urban signage system that transmits, in real time, the level of occupancy of the buses passing by the media facade. Observations and interviews conducted in the area reveal that emojis were successful visual elements to attract people's interest and curiosity. This project highlights the potential of exploring social media graphics in media facades to communicate city-wide topics in a more accessible and friendly language.","PeriodicalId":437505,"journal":{"name":"Proceedings of the 6th ACM International Symposium on Pervasive Displays","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132214399","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 article provides a survey of the use of public displays for public participation in an urban context, covering articles on this topic published between 2012 and 2016. 36 papers were selected and analysed along eight dimensions: type of political context, type of scientific contribution, standalone displays vs displays with a device, single vs multi-purpose displays, shape of displays, lab vs field study, deployment in public vs semi-public space, and the level of public participation addressed. Our analysis revealed a number of trends regarding public displays and public participation in urban settings. Inspecting these articles also led to the observation that current research on public displays is mainly targeting lower levels of public participation and that the evaluation of public displays for public participation in urban settings remains a challenge.","PeriodicalId":437505,"journal":{"name":"Proceedings of the 6th ACM International Symposium on Pervasive Displays","volume":"408 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122734455","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 behavior is commonly referred to as the honeypot effect. At the same time, there are often situations where an audience is present in the vicinity of a public display that does not actively engage or pay attention to the display or an approaching user. However, it is largely unknown how such a passive audience impacts on users or people who intend to interact. In this paper, we investigate the influence of a passive audience on the engagement of people with a public display. In more detail, we report on the deployment of a display in a public space. We collected and analyzed video logs to understand how people react to passive audience in the vicinity of public displays. We found an influence on where interacting users position themselves relative to both display and passive audience as well as on their behavior. Our findings are valuable for display providers and space owners who want to maximize the display's benefits.","PeriodicalId":437505,"journal":{"name":"Proceedings of the 6th ACM International Symposium on Pervasive Displays","volume":"412 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116556695","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}

While public displays can adopt similar authentication concepts like those used on public terminals (e.g., ATMs), authentication in public is subject to a number of risks. Namely, adversaries can uncover a user's password through (1) shoulder surfing, (2) thermal attacks, or (3) smudge attacks. To address this problem we propose GTmoPass, an authentication architecture that enables Multi-factor user authentication on public displays. The first factor is a knowledge-factor: we employ a shoulder-surfing resilient multimodal scheme that combines gaze and touch input for password entry. The second factor is a possession-factor: users utilize their personal mobile devices, on which they enter the password. Credentials are securely transmitted to a server via Bluetooth beacons. We describe the implementation of GTmoPass and report on an evaluation of its usability and security, which shows that although authentication using GTmoPass is slightly slower than traditional methods, it protects against the three aforementioned threats.","PeriodicalId":437505,"journal":{"name":"Proceedings of the 6th ACM International Symposium on Pervasive Displays","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128387280","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 have studied 27 places of various types, analysing their visual display elements and uncovering the key motivations and the main practices behind those non-digital displays. A first result was the identification of a comprehensive set of usage dimensions that provides structure to reason about the design of place-based digital displays as multi-purpose channels. We have also identified fundamental embedded practices that may be leveraged for the design of digital displays. In particular, we have shown that external content plays a key role in place-based communication. Consequently, the ability to support low barrier access to the many external media sources that represent the social, community and business connections of a place should be seen as a fundamental enabler for effective place-based digital display systems.","PeriodicalId":437505,"journal":{"name":"Proceedings of the 6th ACM International Symposium on Pervasive Displays","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130761455","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 demonstrate that although the concurrent use of multiple interaction modalities appeared functionally possible and has the potential to augment a single display with both personal and public functionalities, it is hampered by issues relating to display and interaction blindness, in addition to social discomfort and what we propose to name affordance blindness. We describe this blindness as the inability to understand the interaction modalities of a public display. Overall, passers-by tend to assume that a public display only supports a single interaction modality, an issue that is hard to overcome with ergonomic or visual interventions, or via physical curiosity objects. Although user engagement was relatively limited, we believe that our qualitative results highlight several crucial design and usability aspects when designing multi-modal, interactive public displays. Furthermore, this study demonstrates that previous knowledge on public display interaction cannot be simply ported to other contexts, and that more diverse content-types or contextual use cases should be evaluated \"in-the-wild\" to attain more generalizable insights.","PeriodicalId":437505,"journal":{"name":"Proceedings of the 6th ACM International Symposium on Pervasive Displays","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130489261","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}
