Integrated online localization and navigation for people with visual impairments using smart phones
Ilias Apostolopoulos, Navid Fallah, Eelke Folmer, Kostas E. Bekris
Article No.: 21
DOI: 10.1145/2499669

Indoor localization and navigation systems for individuals with Visual Impairments (VIs) typically rely upon extensive augmentation of the physical space, significant computational resources, or heavy and expensive sensors; thus, few systems have...

Fluid gesture interaction design: Applications of continuous recognition for the design of modern gestural interfaces
Bruno Zamborlin, Frederic Bevilacqua, Marco Gillies, Mark D'inverno
Article No.: 22
DOI: 10.1145/2543921

This article presents Gesture Interaction DEsigner (GIDE), an innovative application for gesture recognition. Instead of recognizing gestures only after they have been entirely completed, as happens in classic gesture recognition systems, GIDE...

Design and evaluation techniques for authoring interactive and stylistic behaviors
James E. Young, Takeo Igarashi, Ehud Sharlin, Daisuke Sakamoto, Jeffrey Allen
Article No.: 23
DOI: 10.1145/2499671

We present a series of projects for end-user authoring of interactive robotic behaviors, with a particular focus on the style of those behaviors: we call this approach Style-by-Demonstration (SBD). We provide an overview introduction of...

Triggering effective social support for online groups
Rohit Kumar, Carolyn P. Rosé
Article No.: 24
DOI: 10.1145/2499672

Conversational agent technology is an emerging paradigm for creating a social environment in online groups that is conducive to effective teamwork. Prior work has demonstrated advantages in terms of learning gains and satisfaction scores when...

Task model-driven realization of interactive application functionality through services
K. Kritikos, D. Plexousakis, F. Paternò
Article No.: 25
DOI: 10.1145/2559979

The Service-Oriented Computing (SOC) paradigm is currently being adopted by many developers, as it promises the construction of applications through reuse of existing Web Services (WSs). However, current SOC tools produce applications that...

Content-based tag propagation and tensor factorization for personalized item recommendation based on social tagging
Dimitrios Rafailidis, Apostolos Axenopoulos, Jonas Etzold, Stavroula Manolopoulou, Petros Daras
Article No.: 26
DOI: 10.1145/2487164

In this article, a novel method for personalized item recommendation based on social tagging is presented. The proposed approach comprises a content-based tag propagation method to address the sparsity and “cold start” problems, which...
