Brain Computer Interfaces
The combination of the synchronized electrical activity of all the neurons in the brain - brainwaves - can be captured in real-time using Brain-Computer Interfaces (BCIs). Portable and affordable BCIs emerged recently, and have the potential to objectively quantify attention and improve learning. We explore the use of BCIs in quantifying user attention in various user interfaces, including an e-Learning platform. For a brief introduction to BCIs please see: Learning Assessment Using Brain-Computer Interfaces: Are You Paying Attention?
3DRTT (3D Radiation Therapy Treatment)
Part of this project is a 3D graphical simulation web-based tool that can be used as a stand alone application to assist in external treatment planning by visually simulating collisions between various LINAC hardware modules. The system is based on X3D and Java programming that allows for accurate simulation of several Linear Accelerators hardware modules. The system helps medical personnel to determine the 3D collision space for a patient and is independent of any computing platform.
Neuro Pathways
Medical students historically have difficulty conceptualizing and projecting the three-dimensional aspects of neural pathways and embryonic organ development from two-dimensional text materials and electronic resources. This collaboration will support the development of interactive three-dimensional simulations systems to allow students to visualize and conceive neural pathways and embryonic development.
X3D for Physics and Chemistry
Many fundamental concepts in physics and chemistry require the development of active mental models for the students to understand the physical and mathematical components. We want to explore student attention and learning of difficult concepts while improving their mental models using 3D augmentation. The proposed research will improve faculty and student expertise in 3D computer-based simulations.
VIEW (Virtual Interactive Engineering on the Web)
The main objective of this project is to implement virtual laboratories to supplement the course: Introduction to Engineering Materials. Hands on laboratories are an essential part of engineering and science education wherein students are introduced to data analysis, report writing, finding empirical correlations between experimental variables and data and to validate theories.
HaptEK-16 (Haptic Environments for K16)
The term haptic is derived from the Greek haptikos, meaning "able to touch." Haptics is the science of applying tactile sensation to computer applications in order to enable users to receive feedback in the form of felt sensations. In this project we are focusing on promoting haptics feedback by presenting a large set of applications that would benefit from the recent developments in Haptics hardware and software especially simulation and training tools for education.
