My research field is related to Neurofeedback, Signal Processing, Brain-Computer Interfaces and Human-Computer Interaction.

Current Work: Neurofeedback Sessions Measurement based on the user's Individual Alpha Peak Frequency

Goal: Present the Individual Alpha Peak Frequency (IAPF) as a standard for predicting the number of sessions of Neurofeedback the patient needs in order to have an improvement in its cognitive ability.

Newborn cry features extraction for affections detection and classification has been intensively developed during the last ten to fifteen years. In this work, methods from the system identification area have been implemented in order to obtain ten Linear Predictive Coefficients (LPCs) plus a nonlinear one stated as Bilinear Intermittent Factor (BIF) per 20 ms analysis window for 40 normal and loss hearing (deaf) newborn cries each. In order to show the contribution of the nonlinear feature, a Kernel Discriminant Analysis (KDA) is performed and afterwards, two classifications tests employing Supported Vector machines (SVMs) as a standard and the Expectation Maximization (EM) algorithm over a Mixture of Experts (ME) operation, considering the BIF as an expert or parent of the LPCs, allows to obtain a 99.84% classification.

This paper presents a platform to support experimentation with applications that enhance user experience in points of interest (POIs) of smart cities by incorporating brain-computer interfaces (BCI). We propose a general architecture for applications in this realm that includes four major layers: Presentation, sensing, action management, and data management. This architecture can be instantiated with various types of BCI sensors and diverse POIs. We describe its components as well as a prototype based on this architecture. We also report on initial findings of the use of our prototype, which show the potential of our approach to support research in the area.

This paper discusses the potential of brain-computer interfaces (BCI) in the interaction between users and objects in points of interest in a city. We present an initial design of the user experience with BCI, aimed to include users with disabilities but also to enhance the experience of the general public. This design includes a physical space to be conditioned specifically for BCI so users can interact with certain objects in a museum, as well as enhancements throughout the museum based on BCI. We report results of a formative evaluation of the main design concepts.
