Design, development, and usability evaluation of a system for adding and editing social media banners in the immersive street-level 3D virtual city

Abstract In this paper, we present design and implementation of a system for adding and visualizing social media content in an immersive street-level 3D virtual city environment. The system enables its users to add banners anywhere in the virtual 3D environment, typically on building façades, walls, or on the ground. The banner’s owner is then able to edit the banner and select the social media platform to load the content from, thereby creating a social media content banner with a specific ID. The system supports four social media platforms: Facebook, Twitter, Pinterest, and Flickr. Users can also customize banners’ position, rotation, and the visual elements such as text, images and colors. To evaluate our system’s usability, we conducted an iterative usability evaluation with 12 participants. Each evaluation round with three participants indicated improvements to the system, which were implemented before next evaluation round. Finally, after the last modifications, system was found to be easy to use by average users and only a little help was needed for non-experienced users. We believe this system could provide added value for the business owners and users by enabling social media content to be add on the 3D virtual city and use it as a marketing platform

Case studies in human information behaviour in smart urban spaces

Abstract This dissertation aims to uncover emerging practices in how people seek information while on the move in augmented urban spaces. The backdrop for a majority of the work presented here is the City of Oulu in Finland, where we have installed a variety of new ubiquitous computing infrastructure and services including, among others, a network of large interactive public displays called UBI-hotspots. The hotspots serve as a versatile platform on top of which new types of services can be developed, deployed and tested in an authentic urban setting with real, non-coached users and a sufficiently long timespan to truly evaluate the impact of such services on the everyday life and practices of the city and its citizens. The case studies presented in this dissertation aim at understanding the effect of such highly visible additions to the urban space from the point of view of human information behaviour. I seek to understand the underlying information seeking strategies people employ while foraging the hotspots for information, and the types of information people see as valuable while attending their daily business in the downtown area of the City. Questions such as how do people utilize the new sources of information in their daily information seeking tasks, and what is the preferred medium for information delivery, are addressed. The theoretical framework for the studies is derived from both ubiquitous and urban computing, and from the field of human information behaviour research. The main findings of the presented studies indicate that people have adapted the new infrastructure and services as parts of their daily information seeking tasks. The detailed usage data logged by all hotspots provide insight into the browsing habits of users, and analysis of inter-session navigation show that various latent strategies of information seeking exist. Further, findings indicate that there is a clear difference between the types of services people perceive as useful prior to using the hotspots, and services that people actually use on the hotspots. Also, findings indicate that people are willing to download information items from the hotspots to their mobile devices for later reference, thus adding information to their personal information repository.Tiivistelmä Tämä väitöskirja pyrkii löytämään ja selittämään uusia tapoja joilla ihmiset etsivät informaatiota älykkäissä kaupunkitiloissa. Tausta suurelle osalle työstä on Oulun kaupunki, jonne olemme asentaneet erilaisia jokapaikan tietotekniikan laitteistoja sekä palveluja. Erityisesti väitöskirjassa tutkitaan suurten julkisten näyttöjen – ”UBI-näyttöjen” – verkostoa. UBI-näytöt toimivat monipuolisena alustana jonka päällä uusia palveluja voidaan kehittää sekä testata autenttisessa kaupunkitilassa todellisten käyttäjien toimesta riittävän pitkällä aikavälillä, joka puolestaan mahdollistaa palveluiden todellisen merkittävyyden arvioimisen suhteessa ihmisten jokapäiväiseen informaatiokäyttäytymiseen sekä informaatiotarpeisiin. Väitöskirjassa esitetyt tapaustutkimukset pyrkivät ymmärtämään tällaisten erittäin näkyvien tietoteknisten laitteiden vaikutusta ihmisten käyttäytymiseen informaatiotutkimuksen näkökulmasta. Tarkastelun kohteena ovat ihmisten jokapäiväiseen tiedonhakuun liittyvät strategiat heidän käyttäessään UBI-näyttöjä, sekä erilaiset informaatiotyypit joita ihmiset pitävät tärkeinä hoitaessaan jokapäiväisiä asioitaan kaupunkitiloissa. Kysymykset kuten kuinka ihmiset käyttävät uusia informaation lähteitä etsiessään tietoa jokapäiväisiin tarpeisiinsa sekä millä laitteilla ihmiset mieluiten etsivät ko. tietoa ohjaavat suurta osaa tutkimuksesta. Tutkimuksen teoreettinen viitekehys muodostuu jokapaikan tietotekniikan tutkimuksesta, urbaanin tietotekniikan tutkimuksesta, sekä ihmisten informaatiokäyttäytymisen tutkimuksesta. Tutkimuksen tärkeimmät löydökset osoittavat että ihmiset ovat ottaneet uudet tietotekniset resurssit osaksi päivittäistä informaatiokäyttäytymistään. Yksityiskohtainen lokitieto yhdistettynä haastattelu- ja havainnointidataan tarjoaa syvällisen näkemyksen käyttäjien tiedontarpeisiin. Dataa analysoimalla olemme havainneet joukon strategioita joita ihmiset käyttävät etsiessään tietoa kaupunkitiloissa. Tutkimus osoittaa myös, että ihmisten oletettujen tiedontarpeiden sekä havainnoidun käyttäytymisen välillä on suuria eroavaisuuksia. Käyttäjät ovat myös halukkaita lataamaan tietosisältöä matkapuhelimiinsa myöhempää käyttöä varten, täten lisäten tietoa omaan henkilökohtaiseen tietovarastoonsa

Soapbox:a situated platform for civic engagement

Abstract This paper presents an interactive Soapbox platform, which utilizes networked public displays to encourage local citizens to participate in civic engagement. Soapbox is comprised of three subsystems: Soapbox for speaker (SFS), Soapbox for audience (SFA) and Shoutbox. SFS allows people to deliver a speech to the public. SFA enables audience members to watch a speech and give feedback to it. Shoutbox is an input tool that runs on personal devices and is used to author comments and share them with the speaker and other members of the audience. The Soapbox system was evaluated in both the lab and the field. The evaluation demonstrated that users are positive about trying the platform, and can quickly grasp how to use it. Further, participants thought that Soapbox is very appropriate for its purpose, and can effectively attract more citizens to participate in civic engagement

Immersive street-level social media in the 3D virtual city:anticipated user experience and conceptual development

Abstract In this paper we explore immersive street-level integration of social media content into collaborative virtual 3D city environments on two levels: i) public, where the virtual environment is populated with relevant social media content (e.g. Twitter and Facebook feeds of shops, non-governmetal organizations, the City organization); and ii) personal, where the virtual user, through his/her avatar, is able to access his/her personal social media feeds while immersed in the virtual city. We conducted a qualitative anticipated user experience study with 14 participants in four focus groups, who were asked to create designs of how they imagined social networking services could be integrated into virtual city environments. Further, participants were asked to comment on two visual concepts created by researchers. Results show that people appreciate the concept of having virtual cities populated with up-to-date content from social media services, but linking their own social media accounts is a more complex issue

Crowdsourcing queue estimations in situ

Abstract We present the development and evaluation of a situated crowdsourcing mechanism that estimates queue length in real time. The system relies on public interactive kiosks to collect human estimations about their queue waiting time. The system has been designed as a standalone tool that can be retrospectively embedded in a variety of locations without interfacing with billing or customer systems. An initial study was conducted in order to determine whether people who just joined the queue would differ in their estimates from people who were at the front of the queue. We then present our system’s evaluation in four different restaurants over 19 weekdays. Our analysis shows how our system is perceived by users, and we develop 2 ways to optimise the waiting time estimation: by correcting the estimations based on the position of the input mechanism, and by changing the sliding window considered inputs to provide better prediction. Our analysis shows that approximately 7% of restaurant customers provided estimations, but even so our system can provide predictions with up to 2 minute mean absolute error

Ubilibrary:situated large public display as interactive interface to library services

Abstract We present the UbiLibrary service developed for a large public display deployed at the lobby of a municipal library. The design of the system was driven by library surveys, interviews of library users and library staff, and analyzing the use of library’s current digital services. The system provides library customers with rich information on library’s services and events through a metadata engine that semantically complements the library’s database with supplementary metadata crawled from online sources and further personalizes information according to the age and gender of the user estimated through face recognition. The service was assessed with a task-based evaluation by library customers, expert evaluation by professional librarians and in the wild field study. The service was found easy to use and regarded as a valuable addition to the library’s digital services. Consequently, it was also deployed on two smaller displays at book collections

Anarchy or order on the streets:review based characterization of location based mobile games

Abstract Location based mobile games have traditionally relied on implicit codes of conduct, legal ordinances, common social norms, or community emergent rules. However, these games are becoming increasingly popular and enforcing these implicit or explicit restrictions has become difficult. In this paper, we present a critical and systematic review of both commercial and non-commercial location based mobile games. We list selected characteristics of the games and highlight their connection to the affordances and restrictions on urban game arenas. We also demonstrate the feasibility of our characterization by applying it to two recent location based mobile games, Pokemon GO [53] and Street Art Gangs [4]

Ludic markers for player-player observation in location-based mobile games

Abstract Background: It can be difficult to capture the subtleties of social behavior during gameplay by using existing commercial location-based mobile games as a research probe since they are not designed to reveal subtleties in player behavior. Aim: We sought to explore whether players spontaneously search for unknown fellow players and to identify ludic markers in player-player observation when playing a digital location-based mobile game that allows location spoofing in addition to automated locationing. Method: We used a constructive research approach and created a game specifically designed to allow location spoofing through self-reporting of player locations. We conducted three field trials with eight participants in total. They took part in separate field trials in groups of three, three, and two players. The participants were previously unknown to each other and commenced play at different locations inside the game area. Results and Conclusions: Qualitative analysis of the gathered video and interview material shows that the players spontaneously searched for unknown fellow players, which confirms earlier research on the topic. Further, behavioral and direct visual markers in the physical environment were reported to be the most significant cues in determining who is a player and who is not
