He is a Principal Researcher at the Cognitive Assistants Systems department and a Research Fellow at DFKI Saarbrücken. Since 2007, he is the head of the Affective Computing Group.

His scientific career started with studying computer science and physics at Saarland University beginning in 1992. He got his diploma in computer science in 1999. In late 2007, he received his doctoral degree in computer science from Saarland University. Since then, he gives seminars and lectures about topics in the affective computing research field at the Saarland Informatics Campus. He was appointed DFKI Research Fellow in November 2020.

Research interests:

  • Computationally Modelling of Affect and internal Processes
  • Medical User Modelling
  • Socially Interactive Agents for Diagnostics and Therapeutic Assistance
  • Affective Computing
  • Human-Computer Interaction
  • Social Training and Learning

Research

Summary

Since 1999 Patrick Gebhard is researching computational models of human affect and its components. His research focuses on human emotional intelligence and its employment for human-computer interaction. He acquired long-term experience evaluating, representing, simulating, and human-like display of emotion. First, he started with simulating emotions for the creation of believable agent behavior in interactive human-agent systems. The need for human empathy in such systems motivated him to extend his expertise to model human emotions since 2011 computationally. For this research, the starting point is the computational processing of physiological, nonverbal, and verbal signals. He further adapts psychological emotions theories to simulate human emotions and their regulations to enable a human-like interaction with computer systems and evaluate socio-emotional interactive human-agent systems for training and therapeutical assistance. This research is conducted in several national and international projects to extend socially interactive agents (SIA) with social-emotional behavior and user models to achieve higher levels of empathy, efficiency, and acceptance of such systems.

Tools

His research group focuses on modeling cognitive models and their exploitation for SIAs, such as 1) creating believable interactive behavior and 2) letting SIAs adapt to users empathically using a user affect model. Within that scope, two internationally highly recognized research tools are offered and continuously maintained to match current requirements and standards:

1. A Layered Model of Affect (ALMA) is the first real-time computational model that integrates the three affect types, emotion, mood, and personality, and various influential aspects on each other, all based on psychological theories and findings. ALMA was first published in 2005 at the international conference on Autonomous Agents and Multiagent Systems (AAMAS ’05).

2. VisualSceneMaker (VSM) is the first visual programming tool that allows modeling parallel interruptive behavior of SIAs featuring separation of content and narrative flow. Since its first implementation, SceneMaker, in 2003, it gets improved continuously to meet interdisciplinary requirements (e.g., from psychology). SceneMaker was first published in 2003 at the second international joint conference on Autonomous agents and multiagent systems (AAMAS ’03). VSM is built upon the research tool SceneMaker introducing concurrency and specific history structures as key concepts to facilitate (1) structured interactive behavior definition, (2) multiple character modeling, and (3) extensions to existing applications. The integrated authoring and executing environment allows action visualization and runtime modifications to support a rapid prototyping style. VSM was first published in 2011 at the Journal on Multimodal User Interfaces 6, 3-11 (2012).
