Wearable Unobtrusive User Interface for Assistive Communication


  1. We are investigating a new concept for assistive communication that promises to be highly portable, unobtrusive, and affordable for people with severe physical disability. The concept leverages recent work being carried out by Dr. Pauca’s research group to extend the user interface of the communication system, e.g. VERBAL VICTOR, onto the person’s body. Associated sensors and algorithms are being developed around the needs of a non-verbal subject with severe cerebral palsy and a prototype will subsequently be tested for efficacy of communication with a small set of subjects at the ALS Center. In addition, this prototype will be used to leverage new research, straddling the fields of machine learning and human-computer interaction, that can lead to end-to-end optimization of the system to the needs of additional user populations.

Planning and Prediction in Complex Environments


  1. We are investigating reinforcement learning and statistical relational learning methods, such as functional gradient boosting, to predict actions of a user. In
    assistive communication, these actions might take the form of buttons being pressed on a system like Verbal Victor. For people with ALS these actions might take the form of specialized keys showing relevant words rather than single letters. In both of these applications the idea is to minimize the number of swipes or keystrokes that the user has to do to express a particular need.

Brain Boot Camp


  1. The main objective of this project is to determine whether the combination of physical and cognitive training, delivered through virtual environments, can have a positive effect in the brains of elder
    adults. Kinect-based games have been developed in-house and are currently being tested in a multidisciplinary project involving Computer Science, Health and Exercise Science, Neuroscience, and Psychology at Wake Forest.

Major directions

We are interested in developing highly affordable modern technology that can bridge the interaction gap between computers and people with physical and cognitive disabilities. Our goal is to exploit recent advancements in machine learning, computer vision, and human computer interaction to use the person’s body as the interface between the computer and the brain, thereby reducing or eliminating the limiting effects of conventional interface devices.
