Enter the Circle: Blending Spherical Displays and Playful Embedded Interaction in Public Spaces
Public displays are used a variety of contexts, from utility
driven information displays to playful entertainment displays.
Spherical displays offer new opportunities for interaction
in public spaces, allowing users to face each other
during interaction and explore content from a variety of
angles and perspectives. This paper presents a playful installation
that places a spherical display at the centre of a
playful environment embedded with interactive elements.
The installation, called Enter the Circle, involves eight
chair-sized boxes filled with interactive lights that can be
controlled by touching the spherical display. The boxes are
placed in a ring around the display, and passers-by must
“enter the circle” to explore and play with the installation.
We evaluated this installation in a pedestrianized walkway
for three hours over an evening, collecting on-screen logs
and video data. This paper presents a novel evaluation of a
spherical display in a public space, discusses an experimental
design concept that blends displays with embedded
interaction, and analyses real world interaction with the
installation
Privacy and Curiosity in Mobile Interactions with Public Displays.
Personal multimedia devices like mobile phones create new needs for larger displays distributed at specific points in the environment to look up information about the current place, playing games or exchanging multimedia data. The technical prerequisites are covered; however, using public displays always exposing information. In this paper we look at these issues from the privacy as well as from the curiosity perspective with several studies showing and confirming users’ reservations against public interactions. Interactive advertisements can exploit this best using specific types of interaction techniques
EyePACT: eye-based parallax correction on touch-enabled interactive displays
The parallax effect describes the displacement between the perceived and detected touch locations on a touch-enabled surface. Parallax is a key usability challenge for interactive displays, particularly for those that require thick layers of glass between the screen and the touch surface to protect them from vandalism. To address this challenge, we present EyePACT, a method that compensates for input error caused by parallax on public displays. Our method uses a display-mounted depth camera to detect the user's 3D eye position in front of the display and the detected touch location to predict the perceived touch location on the surface. We evaluate our method in two user studies in terms of parallax correction performance as well as multi-user support. Our evaluations demonstrate that EyePACT (1) significantly improves accuracy even with varying gap distances between the touch surface and the display, (2) adapts to different levels of parallax by resulting in significantly larger corrections with larger gap distances, and (3) maintains a significantly large distance between two users' fingers when interacting with the same object. These findings are promising for the development of future parallax-free interactive displays
Comparing Free Hand Menu Techniques for Distant Displays using Linear, Marking and Finger-Count Menus
Part 1: Long and Short PapersInternational audienceDistant displays such as interactive Public Displays (IPD) or Interactive Television (ITV) require new interaction techniques as traditional input devices may be limited or missing in these contexts. Free hand interaction, as sensed with computer vision techniques, presents a promising interaction technique. This paper presents the adaptation of three menu techniques for free hand interaction: Linear menu, Marking menu and Finger-Count menu. The first study based on a Wizard-of-OZ protocol focuses on Finger-Counting postures in front of interactive television and public displays. It reveals that participants do choose the most efficient gestures neither before nor after the experiment. Results are used to develop a Finger-Count recognizer. The second experiment shows that all techniques achieve satisfactory accuracy. It also shows that Finger-Count requires more mental demand than other techniques.</p
Attention, An Interactive Display Is Running! Integrating Interactive Public Display Within Urban Dis(At)tractors
Display or interaction blindness is a known problem for interactive public displays where passers-by simply ignore or pay little attention to them. While previous research created interventions that tried to address this problem or reported on differences between experiences in the lab and in the real world, little attention has been given to examining different attractors surrounding the interactive public display, i.e., people, artifacts, and stimuli that compete for people’s attention in the urban settings and distract them from interacting with public displays. This paper reports on a systematic examination of attractors around a case study of an interactive urban display in London. We outline the initial spatial exploration with the aim to identify suitable locations for the placement of the interactive public display within the urban setting, followed by a two-hour observation of attractors and stimuli around the urban display. We highlight the main attractors that compete for people’s attention and distract them from potentially interacting with the public display. We also note our attempt to reflect the environment and integrate the public display within its setting
Supporting tourism with public interactive displays
Interactive displays are common in public and semi-public areas, such as museums, shopping malls, train stations, and even on streets. Especially with the emergence of new ways of interaction, interactive displays could be introduced to popular tourist attractions to support tourism. The aim of this tutorial is to prepare its participants for designing such interactive public displays. The tutorial will first introduce participants to state of the art in interactive public displays. This will be followed by a city tour where a number of local attractions are visited. Finally, the participants will brainstorm and create concepts for novel interactive public displays that aim to improve the experience of visiting tourist attractions
Dynamic graphical user interface generation for web-based public display applications
Public digital displays are moving towards open display networks, resulting in a shift in the focus from single-purpose public displays that are developed with a single task or application in mind, to general- purpose displays that can run several applications, developed by different vendors. In this new paradigm, it is important to facilitate the development of interactive public display applications and provide programmers with toolkits for incorporating interaction features. An important function of such toolkits is to support interaction with public displays through a users' smartphone, allowing users to discover and interact with the public display applications configured in a given display. This paper describes our approach to providing dynamically generated graphical user interfaces for public display applications that is part of the PuReWidgets toolkit
Application diversity in open display networks
We envision that future public display networks will be more interactive and open to applications from third parties similar to what we already have with smartphones. This paper investigates the application landscape for interactive public displays aiming to understand what would be the design and usage space for this type of applications. In particular, we explore people’s perceptions and expectations regarding the diversity of applications that may emerge in future application ecosystems for public displays. We have devised a research methodology anchored on what is currently the rich and diverse range of applications in the mobile application market. We used a set of 75 mobile applications from Google Play application store and asked 72 participants about their relevance for public displays. The results showed that people had a clear preference for applications that disseminate content, and also that these preferences are affected by the type of location where the displays are deployed. These insights improve the understanding of the variables that may affect diversity in future display application ecosystems and inform the development of potential app stores in this context.Fundação para a Ciência e a Tecnologia (FCT
Supporting public participation through interactive
A thesis submitted in partial fulfillment of the requirements for the degree of Doctor in Information Management, specialization in Geographic Information SystemsCitizen participation as a key priority of open cities, gives citizens the chance to
influence public decision-making. Effectively engaging broader types of citizens into
high participation levels has long been an issue due to various situational and technical
constrains. Traditional public participation technologies (e.g. public hearing)
usually are blame for low accessibility by the general public. The development of
Information Communication Technology brings new methods to engage a broader
spectrum of citizens in deeper participation level during urban planning processes.
Interactive public displays as a public communication medium, hold some key advantages
in comparison to other media. Compared to personal devices, public displays
make public spaces into sociable places, where social communication and interaction
can be enriched without intentionally or unintentionally excluding some groups’
opinions. Public displays can increase the visibility of public events while it is more
flexible and up-to-date regarding showing information. Besides, they can also foster
a collective awareness and support group behavioral changes. Moreover, due to the
public nature of public displays, they provide broad accessibility to different groups
of citizens.
Public displays have a great potential in bringing new opportunities to facilitate
public participation in an urban planning process. In the light of previous work on
public displays, the research goal is to investigate a relatively new form of citizen
participation known as Public Display Participation. This participation form refers to
the use of public displays for citizen participation in the context of urban planning.
The main research question of the thesis is how public displays can be used for
facilitating citizen consultation in an urban planning process. First, a systematic
literature review is done to get an understanding of the current achievements and
gaps of research on public displays for public participation. Second, an elicitation
study has been conducted to design end user centered interactions with public
displays for citizens’ consulting activities. Finally, we run a usability to evaluate the
usability of public displays for citizen consultation and their user experience.
The main contributions of this thesis can be summarized as: (1) the identification
of key challenges and opportunities for future research in using public displays
for public participation in urban contexts; (2) two sets of user-defined gestures
for two sets of user-defined phone gestures and hand gestures for performing
eleven consulting activities, which are about examining the urban planning designs
and giving feedback related to design alternatives, are also identified. (3) a new
approach for using public displays for voting and commenting in urban planning,
and a multi-level evaluation of a prototypical system implementing the proposed
approach. Designers and researchers can use the contributions of this thesis, to
create interactive public displays for supporting higher public participat i.e.
citizen collaboration and empowerment
