5th Workshop on Pervasive Advertising

Call for Papers
=================================================================
FIRST CALL FOR PAPERS

5th INTERNATIONAL WORKSHOP ON PERVASIVE ADVERTISING (PerAd5)
In conjunction with Pervasive 2012, 19 June 2012, Newcastle, UK

Submission Deadline: March 9, 2012
=================================================================

At the focus of this workshop we are interested in novel applications of pervasive computing technologies for advertising purposes. Pervasive Advertising is finally gaining importance at a rapidly accelerating pace also outside of research labs, and policy makers, industrial players, and citizen have difficulty in keeping up. The success of this workshop series in exploring and structuring the field has recently been demonstrated by the book on Pervasive Advertising that has been co-authored by leading researchers of the community. The exponential developments identified in the book keep pushing the field forward, and we believe it is crucial to continue the workshop series as a venue for recent developments.

Magical Mirrors 2.0

Yesterday, I visited the Looking Glas installation at a Telekom shop in Berlin that Jörg Müller and his team startet in September this year. Three interactive storefront displays invite passers-by to play virtual soccer. The installation was partly inspired by our Magical Mirrors installation from 2006.

Abstract

Digital immersion is moving into public space. Interactive screens and public displays are deployed in urban environments, malls, and shop windows. Inner city areas, airports, train stations and stadiums are experiencing a transformation from traditional to digital displays enabling new forms of multimedia presentation and new user experiences.

Paper Abstract

Data are presented from observations of Magical Mirrors, a set of four large public displays with gesture-based interaction installed in downtown Berlin, Germany. The displays show a mirror image of the environment in front of them and react with optical effects to the gestures of the audience. Observations of audience behavior revealed recurring behavioral patterns, like glancing at a first display while passing it, moving the arms to cause some effects, then directly approaching one of the following displays and positioning oneself in the center of the display. This was often followed by positioning oneself in the center of the other displays to explore the possibilities of the different effects, and sometimes by taking photographs or videos. From these observations a framework of interaction with gesture-based public display systems was deduced. It describes the phases of passing by a display, viewing & reacting, subtle interaction, direct interaction, multiple interactions, and follow-up actions. Quantitative data of these behavioral phases was collected by observing 660 passers-by on 2 weekend evenings. This article shows how many passers-by pass the thresholds between these phases. This “Audience Funnel” should provide a framework to encourage systematic investigation of public display systems and enable comparability between different studies.

Evaluating Natural User Interfaces for Public Displays in the Wild

by Jörg Müller, Daniel Michelis, Chris Kray
Position Paper, Workshop Natural User Interfaces, CHI 2010

Abstract

One major application area of Natural User Interfaces are public displays, which are often not intended to help the user fulfill a certain task, but rather to be engaging, inspiring and entertaining. A key issue in this area is how to evaluate these systems and their user interfaces. Based on the case study of Magical Mirrors, we identify challenges that occur with evaluating such systems and propose ways to address these evaluation challenges. Challenges include the lack of a welldefined task, the difficulty of describing and observing audience behavior, the briefness and sparseness of typical interactions, and the public nature of the space.

Introduction

Public Displays are by definition provided for a very broad user base, many of whom will not have encountered the display before. For such situations, Natural User Interfaces (NUIs), which aim to be learnable very quickly, are ideally suited. Such NUIs can involve touch [5] or gestures [4]. Typically, people pass by such displays at a distance, where gestures are well suited to initiate interaction. Rather than to support the user in a specific task, we argue that the most interesting application of such public displays may be to engage, inspire and entertain the audience. The fun of interaction may be an end in itself. We deployed Magical Mirrors, a set of public displays where passers-by can interact with gestures, and manually observed how the public interacted with the displays. We report on the challenges we encountered while evaluating the system and indicate ways to address these challenges.

CfP: PERVASIVE 2010 Workshop in Helsinki

I am co-organizing a workshop on Pervasive Advertising and Shopping. The workshop will be held in conjunction with Pervasive 2010, May 17 2010, in Helsinki, Finland

Pervasive computing technologies such as a variety of public digital displays, ever-smaller mobile devices, and location sensing and tracking tools are rapidly adopted by the advertising and retail industries. Adoption is driven by the comprehensive business models facilitated by these technologies, a fact that leads us to believe that advertising and shopping could well be amongst the most important deployment domains for pervasive technologies. Furthermore, the two industries are intimately linked: advertising that is the communication of sponsored messages to inform, convince, and persuade to buy leads to shopping, that is the examination and purchasing of goods.

However, the opportunities, benefits and drawbacks of pervasive technologies in these domains only now are beginning to be understood. Moreover the current trend whereby power is shifting towards consumers, makes specific aspects of advertising and shopping such as brand experience, word of mouth, and audience measurement gain importance, and provides opportunities for pervasive technologies to generate some true benefit for consumers.

Collaborative Interaction with Public Displays

In interacting, groups exhibit a very special dynamic. If a group of two or more people pass by the public displays, most often just one person becomes the active one who starts the interaction. This person pauses, then actively participates in the interaction drawing the attention of the other group members toward him or herself. Typically the others initially stand by and hesitantly observe the interaction.

In the parts of the investigation in which more than one display was available the other members of the group began to use the free displays and explore the interaction possibilities. Little by little the entire group participated in the interaction. In the cases in which there was only one display, the group became impatient and the most active person was encouraged to rejoin the group and move on.
