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.

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.

Calm Advertising – Position Paper

[tweetmeme source="michelis"]

After a fruitful discussion at the Pervasive Advertising Workshop on May this year, I hope to continue the diaologue on Calm Advertising next Friday at the Informatik 2009 conference.

As I wrote earlier about the first Workshop on Pervasive Advertising:

“The workshop topic inspired us to develop a concept of “Calm Advertising” that refers to the vision of “Calm Computing” and focuses on a new way of public advertising that doesn`t aim to shout out lout messages to get peoples attention but enable passers-by to freely engage in the communication with advertising companies.”
