We propose and validate a model of the perception area of content on public displays in order to predict from where users can read. From this model, we derive Screenfinity, a technique to rotate, translate, and zoom content in order to enable reading while passing by very large displays. Screenfinity is comfortable to read when close, supports different content for different users, does not waste screen real estate and allows expert passers-by to read content while walking.

"Big Screen Is Watching Me?": A Study on the Attractiveness and Reading Efficiency of a Rotating Screen
TLDR
A rotating screen that adapts to a passerby’s movement in real-time is more effective in both attracting passerby attention and improving screen reading efficiency.
Readability in Multi-User Large-Screen Scenarios
TLDR
Evaluation of the results shows that the typical text moving direction (right to left) is not always the optimal choice, and when just one user is standing in front of the screen the results showed a preference for a vertical text movement.
Increasing Passersby Engagement with Public Large Interactive Displays: A Study of Proxemics and Conation
TLDR
The study of conation found that "conceptual" visuals designed to evoke indirect conation were also useful in attracting people's attention and showed that random triggers were more effective than proxemic triggers at overcoming display and interaction blindness.
The puppeteer display: attracting and actively shaping the audience with an interactive public banner display
TLDR
A wide interactive banner display installed at a city sidewalk is presented and dynamic visual stimuli such as frames and ellipses are effective to direct users in front of the display and manipulate the audience like a puppeteer, thus reversing the notion of adaptive content being implicitly manipulated by the users.
Fostering large display engagement through playful interactions
TLDR
Two simple whole body (non-touch) interactions with a public display, one a user skeleton and the second a simple game, are explored to explore their relative efficacy at capturing passers-by attention and at keeping passers- by engaged.
Studying Attraction Power in Proxemics-Based Visual Concepts for Large Public Interactive Displays
TLDR
This study conducted a study to the effectiveness of promising visual concepts applied in a proxemic interactions framework: content motion and user shadows, which were found to be ineffective for communicating possible user interactions in the display.
A laboratory-based study methodology to investigate attraction power of large public interactive displays
TLDR
This work developed a complementary laboratory-based study methodology that employs experimental deception to assess the ability of an interface design solution to attract a passerby's attention and requires minimal setup.
Multi-tiles: a System for Information Presentation using Divided Rotatable Screens
TLDR
A presentation system using a multi-tiled screen divided into 3x3 multiple rotatable panels and by rotating the surface of the projection, the presenter can select which information the viewers can see.
Compensating for Perspective-based Distortion on Large Interactive Floor Displays: the SpaceHopper Field Experiment
TLDR
A perspective compensated view technique that maintains the relative size and shape of objects as they move away from the viewer is introduced, and it is explored in SpaceHopper, a large-scale, floor-projected version of the game Asteroids.
Information Visualization and Proxemics: Design Opportunities and Empirical Findings
TLDR
This work implements interaction techniques that zoom and pan, query and relate, and adapt visualizations based on tracking of users' position in relation to a large high-resolution display, focusing here on the spatial relations between a single user and visualizations on a large display.

Looking glass: a field study on noticing interactivity of a shop window
TLDR
An interactive installation is designed that uses visual feedback to the incidental movements of passers-by to communicate its interactivity and reveals mirrored user silhouettes and images are more effective than avatar-like representations.
Proxemic peddler: a public advertising display that captures and preserves the attention of a passerby
TLDR
The Peddler Framework captures fine-grained continuous proxemic measures by monitoring the passerby's distance and orientation with respect to the display at all times, and uses this information to infer the passersby's interest or digression of attention at any given time.
E-conic: a perspective-aware interface for multi-display environments
TLDR
The design and implementation of E-conic is presented, a multi-display multi-user environment that uses location data about displays and users to dynamically correct perspective and shows that perspective correction significantly and substantially improves user performance in all these tasks.
Chained displays: configurations of public displays can be used to influence actor-, audience-, and passer-by behavior
TLDR
This paper presents Chained Displays, a combination of several screens to create different form factors for interactive public displays and presents a design space based on two complementary concepts, Focus and Nimbus, to describe and compare chained display configurations.
Spotlight: directing users' attention on large displays
TLDR
The behavior of spotlights is defined, unique affordances of the technique are shown, and the benefit of using the spotlight a large display and standard desktop configuration is reported.
It's Mine, Don't Touch!: interactions at a large multi-touch display in a city centre
TLDR
Detailed observations of CityWall, a large multi-touch display installed in a central location in Helsinki, Finland, are presented to analyze how public availability is achieved through social learning and negotiation, why interaction becomes performative and, finally, how the display restructures the public space.
Range: exploring implicit interaction through electronic whiteboard design
TLDR
This work presents a framework for implicit interaction and applies it to the design of an interactive whiteboard application called Range, a public interactivewhiteboard designed to support co-located, ad-hoc meetings.
Multitoe: high-precision interaction with back-projected floors based on high-resolution multi-touch input
TLDR
This work integrates high-resolution multitouch input into a back-projected floor that allows the floor to ignore users unless they interact explicitly, identify and track users based on their shoes, enable high-precision interaction, invoke menus, track heads, and allow users to control high-degree of freedom interactions using their feet.
Measuring environments for public displays: a space syntax approach
TLDR
An on-going project, which is investigating the role that location plays in the visibility of information presented on a public display, offers a new way to consider the role of space in guiding and constraining interaction in real settings.
Mnemonic rendering: an image-based approach for exposing hidden changes in dynamic displays
TLDR
An image-based storage, visualization, and implicit interaction paradigm called mnemonic rendering is proposed that provides better support for handling visual changes and once implemented on a system, can benefit all applications.
