Introduction
Ella Velner just started a 4-year PhD in Child-Robot-Media Interaction, with a focus on voice and privacy awareness. In July 2019, she graduated from the University of Amsterdam in Information Systems (MSc). With a Bachelor's degree in Communication and Information Sciences, she combines the user's view with the view of the programmer and wants to align these two to create the best systems, with a focus on the interaction.

Chapter
Karen is a conversational agent taking the role of an angry customer in a retail context. While the user (retail employee) tries to convince Karen to follow the rules, the agent interrupts the user, and verbally and nonverbally reacts to the user’s sentiments.
Chapter
This work presents a conversational agent (CA) that functions as a prototype for simulating interrogations. The solution implements a cognitive model that focuses on the interpersonal relationships between the CA and the user. This model can adjust the interpersonal stance of the CA based on the sentiment and phrasing of the user’s utterances. As a...

Our research project (CHATTERS) is about designing a conversational robot for children's digital information search. We want to design a robot with a suitable conversation, that fosters a responsible trust relationship between child and robot. In this paper we give: 1) a preliminary view on an empirical study around children's trust in robots that...

In this paper, we identify challenges in children's current information retrieval process, and propose conversational robots as an opportunity to ease this process in a responsible way. Tools children currently use in this process, such as search engines on a computer or voice agents, do not always meet their specific needs. The conversational robo...

Since trust measures in human-robot interaction are often subjective or not possible to implement real-time, we propose to use speech cues (on what, when and how the user talks) as an objective real-time measure of trust. This could be implemented in the robot to calibrate towards appropriate trust. However, we would like to open the discussion on...

The more people commute by bicycle, the higher is the number of cyclists using their smartphones while cycling and compromising traffic safety. We have designed, implemented and evaluated two prototypes for smartphone control devices that do not require the cyclists to remove their hands from the handlebars - the three-button device Tribike and the...

Human-robot interaction (HRI) research aims to design natural interactions between humans and robots. Intonation, a social signaling function in human speech investigated thoroughly in linguistics, has not yet been studied in HRI. This study investigates the effect of robot speech intonation in four conditions (no intonation, focus intonation, end-...

In this paper we report our first attempt on building a Human-Agent Interaction (HAI) open-source toolkit to build HAI applications. We present a human-robot interaction application using the Cozmo robot built using different modules. The scenario of this application involves getting the agent’s attention by calling its name (Cozmo), then interacti...
