Research in mobile text entry has long focused on speed and input errors during lab studies. However, little is known about how input errors emerge in real- world situations or how users deal with these. We present findings from an in-the-wild study of everyday text entry and discuss their implications for future studies.

We argue that measuring the Inviscid text entry rate requires new evaluation methods that support freeform text entry and that are not based on the traditional transcription/copy tasks. In this position paper we propose use of image description tasks and share some of our experiences of using this new language agnostic task type for free form text entry

Smartphone notifications are a major source of interaction with mobile devices. In this paper we address a gap in literature by establishing a foundation that explains the role of modalities with which a notification is delivered on a mobile device. Though previous studies have attempted to address this question, we find that they suffer from significant internal validity problems. As such we conducted an ecologically valid and carefully designed experiment in a controlled environment that simulates a smart home environment. Our work extends into smart environments, by examining a new modality, implemented by pairing the smartphone to a connected lighting system and replicating mobile notifications to smart light bulbs in the user’s field of vision. We derive a set of guidelines for choosing notification modalities and set future research directions.

The European Conference on Ambient Intelligence (AmI, http://www.amiconferences.org/) is the prime venue for research on Ambient Intelligence, with an international and interdisciplinary character. It brings together researchers from the fields of science, engineering and design, working towards the vision of Ambient Intelligence. AmI-15 was held in Athens, Greece, November 11-13, 2015 (http://www.ami-conferences.org/2015/) and provided a meeting point for each of these communities, aiming for intensive networking and scientific debate, as well as shaping visions of the future. This CEUR Volume corresponds to the adjunct proceedings of AmI-15, containing the poster papers as well as the papers presented in the Workshop entitled “Affective Interaction with Avatars”, which was organized by Carsten Stocklöw, Sten Hanke, Maher Ben Moussa, Panayiotis Andreou and Christiana Tsiourti, and held in the scope of the EU-funded Miraculous-Life project (http://www.miraculous-life.eu/). All the contributions have been reviewed by at least three experts, comprising of members of the AmI-15 Committee and external reviewers, as listed below: Honorary Chair Emile Aarts, Tilburg University, The Netherlands Conference Chairs Achilles Kameas, Hellenic Open University, Greece Irene Mavrommati, Hellenic Open University, Greece Program Chairs Boris De Ruyter, Philips Research, The Netherlands Periklis Chatzimisios, Alexander TEI of Thessaloniki, Greece Thematic Chairs Massimo Zancanaro, Bruno Kessler Foundation, Italy Reiner Wichert, Fraunhofer, Germany Vassilis Kostakos, University of Oulu, Finland Dimitris Charitos, National Kapodistrian University of Athens, Greece Christos Goumopoulos, University of the Aegean, Greece Ioannis Chatzigiannakis, University of Rome La Sapienza, Italy Vanessa Evers, University of Twente, The Netherlands Workshops Chairs Andreas Komninos, University of Strathclyde, UK Vassilis Koutkias, INSERM, Paris, France Posters and Demos Petros Nikopolitidis, Aristotle University of Thessaloniki, Greece Javed Vassilis Khan, Eindhoven University of Technology, The Netherlands
