Predicting mid-air gestural interaction with public displays based on audience behaviour

2020

Abstract Knowledge about the expected interaction duration and expected distance from which users will interact with public displays can be useful in many ways. For example, knowing upfront that a certain setup will lead to shorter interactions can nudge space owners to alter the setup. If a system can predict that incoming users will interact at a long distance for a short amount of time, it can accordingly show shorter versions of content (e.g., videos/advertisements) and employ at-a-distance interaction modalities (e.g., mid-air gestures). In this work, we propose a method to build models for predicting users’ interaction duration and distance in public display environments, focusing on …

Touchless Interfaces For Public Displays

2016

Public displays have lately become ubiquitous thanks to the decreasing cost of such technology and public policies supporting the development of smart cities. Depending on form factor, those displays might use touchless gestural interfaces that therefore are becoming more often the subject of public and private research. In this paper, we focus on touchless interactions with situated public displays, and introduce a pilot study on comparing two interfaces: an interface based on the Microsoft Human Interface Guidelines (HIG), a de facto standard in the field, and a novel interface, designed by us. Differently from the HIG-based one, our interface displays an avatar, which does not require an…

Supporting tourism with public interactive displays

2019

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 e…

Designing Touchless Gestural Interfaces for Public Displays

Nell’ultimo decennio, molti autori hanno studiato la possibilità di utilizzare le interfacce a gesti come strumento innovativo per supportare l’interazione con i computer. Inoltre, le recenti innovazioni tecnologiche hanno permesso di installare display interattivi in ambienti privati e pubblici. Tuttavia, l’interattività di tali display è spesso basata sull’uso di touchscreen, mentre tecnologie come i dispositivi Kinect-like vengono adottate molto più raramente, soprattutto se si considera l’ambito dei display pubblici. Al giorno d’oggi, l’opportunità di studiare le interfacce touchless per i display pubblici è diventata concreta, e rappresenta il campo di studio di diversi ricercatori. L’…

Touchless gestural interfaces for networked public displays

2015

In the near future, we can easily imagine a significant increment in diffusion of networked public displays, as well as novel interaction modalities used in their applications. In the following, we present two of the main challenges related to networked displays we are dealing with, with a particular focus on touchless gestural interfaces: overcoming interaction blindness (i.e. enable users to immediately guess the interactivity of the display, and the gestural nature of it) and performing evaluations in-the-wild (i.e. outside any controlled environment).

The Screen Is Yours—Comparing Handheld Pairing Techniques for Public Displays

2013

Whereas mobile devices have been heavily investigated as remote controls for distant displays, research on the fundamental first step, the pairing with the display, is scarce. In a comparative user study with 31 participants we evaluated five potential pairing techniques concerning their performance and acceptance for connecting to a public display and gained insights into the general requirements for pairing techniques in this special usage context. Besides four established mobile interaction techniques (touching an NFC tag, capturing a QR code, scanning, and manual input), our study considered a recent appropriate pairing technique called display pointing, which allows passers-by to conne…

Exploiting social comparison using pervasive displays and mobile notifications for reducing energy consumption

2017

Abstract Public displays have been used as a persuasive technology in many prior works. In this paper, we describe a persuasive pervasive system aimed at influencing users’ behavior for reducing energy consumption in buildings. This system exploits a pervasive display that visualizes the energy consumption in different levels (rooms, floors, and buildings), exploiting social comparison techniques. Moreover, our system may be extended by means of a mobile application that sends persuasive personalized messages to the users regarding their energy consumption. We then present our evaluation study design, aimed at comparing the effectiveness of three possible implementation of our system: one b…

Exploring usability and accessibility of avatar-based touchless gestural interfaces for autistic people

2018

Many prior works investigated the potential of pervasive technologies and interactive applications to increase access capabilities to digital content for people with disability, particularly Neuro-Developmental Disorders (NDDs). In this paper, we present an exploratory study aimed at understanding if an avatar-based touchless gestural interface is able to foster interest towards digital representations of artworks, e.g. paintings or sculptures usually exhibited in museums, and to make them more accessible for such people. In particular, the study involved three autistic people and a therapist, and allowed us to report the potential of an avatar to communicate the interactivity and stimulate…

They are looking at me! Understanding how Audience Presence Impacts on Public Display Users

2017

It is well known from prior work, that people interacting as well as attending to a public display attract further people to interact. This behavior is commonly referred to as the honeypot effect. At the same time, there are often situations where an audience is present in the vicinity of a public display that does not actively engage or pay attention to the display or an approaching user. However, it is largely unknown how such a \textit{passive audience} impacts on users or people who intend to interact. In this paper, we investigate the influence of a passive audience on the engagement of people with a public display. In more detail, we report on the deployment of a display in a public s…

Ecological Invitation to Engage with Public Displays

2018

Interactive public displays pose several research issues, which include display blindness and interaction blindness. In this paper, we shortly introduce our idea of a sound-based system to overcome the display blindness, and some experiments that we are carrying out in order to test its effectiveness.
