Reza Moradinezhad

Computer Science PhD Candidate
Drexel University

I am a PhD candidate in Computer Science at Drexel University College of Computing and Informatics. I work with Dr. Erin Solovey at Advanced Interaction Research Lab.

After graduating my B.S. in IT Engineering from University of Mazandaran, Iran in 2013, and after two years of teaching and freelancing in Website and Windows application development, I started my PhD program at Drexel University in 2015. My research involved using physiological data, namely brain data acquired by functional Near Infrared Spectroscopy (fNIRS) as a means of feedback for Human Computer Interaction (HCI).

My current project looks at factors of trust between Humans and Embodied Virtual Agents (EVAs). We look at how an agent's inconsistent behavior can affect the human's trust. We also explore how one agent's behavior can cause a human to perceive another agent's trustworthiness differently. The current focus of the project on building a machine learning (ML) model to predict users' trust toward EVAs.

Research Interests:

Human-Computer Interaction: Trust, Embodied Virtual Agents, Brain-Computer Interfaces

Virtual Reality: Computer Games, Immersive Environments, Simulations

Computational Intelligence: Machine Learning, Pattern Recognition, Feature Selection

Human Trust toward Embodied Virtual Agents

An experiment to study the change in human trust towards assistive embodied virtual agents when presented to agents with different levels of consistency during a question and answer task. One of the important goals of this project is to see how interaction with one agent can change the perceived/expected trust in a previous/future agent:

  • Designed the experiment

  • Mentored two undergraduate student to build two embodied virtual agents capable of showing different facial expressions using Unity and help with the coding of the interface

  • Mentored a master’s student at Worcester Polytechnic Institute to work on a part of this project as their master’s thesis

  • Built a Unity Interface using C#

  • Ran experiments and collected and analyzed the data

  • Built a machine learning model to predict users’ trust

  • Wrote papers based on the obtained results

   

Mind Wandering in SART
Using functional near infrared spectroscopy to find hemodynamic differences in brain tissue between mind-wandering and focus periods during a Sustained Attention to Response Task (SART):

  • Mentored an undergraduate student to modify the experiment design and run the experiments

   

fNIRS Data Visualization

Developing a user interface in Matlab to visualize the data collected by fNIRS device. This includes the ability to show a certain section of data, for example a specific channel or a specific event. It also adds the ability to apply multiple filters and perform different preprocessing procedures:

  • Mentored an undergraduate student to come up with the design and then implement different parts of the design

     

Creativity and Brainstorming Study
Investigating the effectiveness of semantically far inspirations provided by a creativity support tool by observing the changes in participants’ cognitive workload using functional near infrared spectroscopy:

  • Helped with modifying the experiment design

  • Helped with running the experiments and collecting data

  • Helped with writing a paper based on the obtained results

   
Intelligent Tutoring System Study

Investigating the changes in participants’ attention and cognitive workload using functional near infrared spectroscopy while they solved math problems by the help of an intelligent tutoring system; with the aim of understanding the necessary steps toward making neuroadaptive learning environments:

  • Helped with running the experiments and collecting data
