Interpreting Hash Function Security Proofs

We provide a concrete security treatment of several "provably secure" hash functions. Interpreting arguments behind MQ-HASH, FSB, SWIFFTX and VSH we identify similar lines of reasoning. We aim to formulate the main security claims in a language closer to t ...

Task Performance vs. Learning Outcomes: A Study of Tangible User Interface in Classroom Setting

Pierre Dillenbourg, Patrick Jermann, Guillaume Zufferey, Sébastien Cuendet

Tangible User Interfaces (TUIs) offer the potential to facilitate collaborative learning in new ways. This paper presents an empirical study that investigated the effects of a TUE in a classroom setting on task performance and learning outcomes. In the tan ...

The 3A Personalized, Contextual and Relation-based Recommender System

Denis Gillet, Christophe Salzmann

This paper discusses the 3A recommender system that targets CSCL (computer-supported collaborative learning) and CSCW (computer-supported collaborative work) environments. The proposed system models user interactions in a heterogeneous graph. Then, it appl ...

Human Awareness to Interface Errors Improves HCI Performance

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Andrea Biasiucci, Daniel Roggen

We explore the use of brain activity in scenarios of Human-Computer Interaction. Specifically, we aim at the detection of EEG correlates of error awareness to dynamically adapt a Human activity recognition system. We design a Human Computer Interaction exp ...

Anticipation based Brain-Computer Interfacing (aBCI)

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Gangadhar Garipelli

Abstract—Anticipation increases the efficiency of daily tasks by partial advance activation of neural substrates involved in it. Previous off-line studies have shown the possibility of exploiting this activation for a Brain-Computer Interface (BCI) using e ...

Mechanisms for Making Crowds Truthful

Boi Faltings, Radu Jurca

We consider schemes for obtaining truthful reports on a common but hidden signal from large groups of rational, self-interested agents. One example are online feedback mechanisms, where users provide observations about the quality of a product or service s ...

Using reinforcement learning for optimizing the reproduction of tasks in robot programming by demonstration

Florent Günter

As robots start pervading human environments, the need for new interfaces that would simplify human-robot interaction has become more pressing. Robot Programming by Demonstration (RbD) develops intuitive ways of programming robots, taking inspiration in st ...
