Development of a biosignals framework for usability analysis

The understanding of human physical and physiological signals and expressions, together with a growing processing and control capacity allows for new approaches in interactive systems design. In this poster, we introduce constitutive elements and steps towards the integration of EEG (Electroencephalography) signals in a system to analyze reading activities. The poster presents system design choices that include the software architecture and the feature extraction and classification techniques used in the first prototypes. Categories and Subject Descriptors H.5.2 [Information Interfaces and Presentation]: User Interfaces – user centered design, evaluation/methodology. General Terms Design, Experimentation, Human Factors. Keywords EEG signals, Usability Analysis
