Virtual Agents, Social Robots, Human-Computer Interaction, Human-Robot Interaction,?Multimodal User Interfaces
?
My research focuses on the development of multimodal dialog systems for intuitive communication between humans and computer-controlled social agents.
Among other things, this includes the generation of believable, life-like behavior for virtual characters and robots which?allows the user to understand their cognitive state. Furthermore, I am interested in modern input technology like speech, facial expressions and gestures because those agents, in turn, should be able to understand naturally-occurring human behavior.
Projects
Decision-Theoretic Personality-Based Turn-Taking
For my doctoral thesis I am examining different factors which influence the turn-taking in dialogue, and how these mechanisms can be applied to artificial characters.
The focus is on behavior patterns which express the personality and the interpersonal stance towards the interlocutor.

Supervised Student Projects
Description
For this project I supervised two students who programmed an emotional game-playing companion. For this purpose?two different personalities were modeled - a friendly partner and a hostile rival - who react differently to game events and express this verbally as well as using facial expressions.
?
This application was used in the context of the ForGenderCare project in order to examine how elderly people interact with social robots.

Description
?
This demonstration was created for the "Lange Nacht der Wissenschaft" ("The Long Night Of Science") which took place on May 5th 2018 in Augsburg.
?
Here the social robot Reeti serves as a nutrition advisor who informs the user about the calorie content of the offered drinks. By means of custom-made drink holders and an electronic scale the system can detect how much the user?drinks of which juice. Based on the amount of calories in the cup a reward is calculated for the information strategy used beforehand, in order to adapt the probability that it is chosen in the future via reinforcement learning. This way the robot is supposed to learn whether the user is convinced more easily by pointing out high or low calories.
?
In the winter semester of 2018/19 this?system was also used to illustrate potential applications of social robots in?retirement homes. In the context oft the course?"Multimedia 1: Usability Engineering"?a group of students presented this recommendation robot in three different retirement homes in the region of Augsburg. Afterwards, they discussed potential uses and the requirements for this technology with the inhabitants and the care staff.

Description
The simplest form of empathy is mirroring the emotions which are being observed from the?interlocutor. Humans usually do this subconsciously.
?
Our current prototype employs the?Social Signal Interpretation Framework (SSI) to analyse the tone of voice and the facial expressions of the user. The recognized emotions are then mapped to numerical values along the two axes "pleasure" and "arousal".
?
The robot we use, "Zeno", is a?RoboKind R50?built by the?Texan?company Hanson Robotics.?He has a human-like body and additional servo motors under a synthetic skin which allow for the adaptation of his facial expressions. The appliation which controls his behavior continually adapts his facial expression and head pose to the emotional state which was recognized by the SSI pipeline.
?
Additionally, Zeno?has?several lists of sentences which he can use to comment on the situation when user pauses in their speech. The exact moment when the robot talks depends on various factors, for example the intensity of the current emotional state or the time which has passed since the last comment.

Description
For?this application the human's task is to place different objects on the given?fields. The robot's instructions for this are kept intentionally ambiguous in order to make the human ask for clarification.
?
The eye tracking glasses worn by the user, as well as special markers on the objects, enable the system to detect which object the user is currently looking at. This in turn enables the robot to resolve ambiguities in the user's spoken question, so it can answer correctly.
?
Furthermore, this information allows the robot to show gaze behavior which expresses joint attention. For example, it follows the user's gaze to the respective objects or makes eye contact when the former looks at the robot.
?
This eye contact also serves as a signal for conversational floor management. When the user asks a question, the robot delays its answer and waits until the user looks at it directly.
All these behavior patterns serve to establish the common ground in order to avoid misunderstandings or at least resolve them quickly.
