Las interfaces HCI y PC basadas en bioseñales constan de 3 fases: la captación de los datos, procesamiento y actuación sobre el sistema. El trabajo de esta tesis está centrado en el bloque de procesamiento de la información registrada por los electrodos. La naturaleza heterogénea de las bioseñales implica diferentes técnicas de captación y...

Background: Eye movements have been used in control interfaces and as indicators of somnolence, workload and concentration. Different techniques can be used to detect them: we focus on the electrooculogram (EOG) in which two kinds of interference occur: blinks and overshoots. While they both draw bell-shaped waveforms, blinks are caused by the...

The aim of this paper is to identify heart rate parameters with higher significant values when a set of people are performing a task under stress condition. In order to accomplish this, one computer application with arithmetic and memory activities which lets drive the subjects to different stages of activity and stress has been designed. Tests...

The goal of this study is to identify EEG parameters and electrode positions with the highest significant values to differentiate between tasks and relax periods. Different signals were recorded as 12 subjects are doing arithmetic and memory tasks under stress condition. The test consisted of an initial and final 5-minute relax periods and...

The electrocardiogram (ECG) is a well-established technique for determining the electrical activity of the heart and studying its diseases. One of the most common pieces of information that can be read from the ECG is the heart rate (HR) through the detection of its most prominent feature: the QRS complex. This paper describes an offline...

In this paper we propose an assessment of biosignals for handling an application based on virtual keyboard and automatic scanning. The aim of this work is to measure the effect of using such application, through different interfaces based on electromyography and electrooculography, on cardiac and electrodermal activities. Five people without...

A five-layered software architecture translating movements into mouse clicks has been developed and tested on an Arduino platform with two different sensors: accelerometer and flex sensor. The archi-tecture comprises low-pass and derivative filters, an unsupervised classifier that adapts continuously to the strength of the user's movements...

This In this paper, a system architecture that can be adapted to an individual's motor capacity and preferences, to control a computer is presented. The system uses two different transducers based on the emission and the reflection of infrared light. These let to detect of voluntary blinks, winks, saccadic or head movements and/or sequences of...

In this paper we propose an application based on virtual keyboard and automatic scanning to communicate with a PC and the others people. The aim users are the people with disabilities. A high degree of customization is possible in the software. So the user can selected the color of buttons, position of system on screen, the kind of scanning,...

In this paper a thermal flowmeter based on the calorimetric principle is reported and analytically modeled. The flow is measured without using any kind of laminar or bypass elements and it has been tested for laminar, transitional and turbulent flow patterns. It contains four temperature sensors. Three of them are placed downstream and the...

This paper presents an exhaustive study on the different topologies of ambiguous soft keyboards, analyzing the text entry average time per character and the average number of user inputs necessary for its creation. Various topologies and design criteria are investigated. In addition, an analytical model is also proposed. This model allows one...

This paper presents a proposal of a flexible telemedicine system for remote patient monitoring. It can be used in different kind of environments where there is only available low speed transmission links like Radio Frequency. This proposal includes the use of a previous work where the IEC-60870-S standard was applied to the development of an...

This paper presents a work in progress for the developing of a fingerprint indoor position system based on OpenMAC, an IEEE 802.15.4 embedded software implementation from Atmel to be used in different scenarios like e_health, ambient living or smart building. The system is thought to work as another one that we have yet developed but using the...

In this paper, a signal processing algorithm to detect eye movements is developed. The algorithm works with two kinds of inputs: derivative and amplitude level of electrooculographic signal. Derivative is used to detect signal edges and the amplitude level is used to filter noise. Depending of movement direction, different kinds of events are...

This work studies the feasibility of using mental attention to access a computer. Brain activity was measured with an electrode placed at the Fp1 position and the reference on the left ear; seven normally developed people and three subjects with cerebral palsy (CP) took part in the experimentation. They were asked to keep their attention high...

Body Area Networks are a solution to remote monitoring in order to acquire vital signals of patients. Actual sensors provide its own interface which makes more difficult to integrate them in a system. Using standardized protocols and interfaces increases the usability and the integration of different sensors, to achieve this goal the IEEE 1451...

Applications involving data acquisition from sensors need samples at a preset frequency rate, the filtering out of noise and/or analysis of certain frequency components. We propose a novel software architecture based on open-software hardware platforms which allows programmers to create data streams from input channels and easily implement...

Multisensory stimulation therapy involves the simultaneous stimulation of several senses in a relaxing environment to achieve a variety of therapeutic outcomes for client with conditions affecting sensory and cognitive processes. We present, StimuHat, a wearable system for therapists to visually stimulate patients. We conducted a pilot study in...

Physical activity (PA) performed in group can slow down the decline in motor functions in people with disabilities. With this objective, Interactive Rehab Orchestra (IRO) was developed. IRO is an interactive multiplayer musical game that looks for reducing sedentary lifestyles by promoting PA. The individuals are responsible for playing the...

In this work, music is used to elicit emotions and the impact produced by it on the electrocardiogram and electroencephalogram signals is measured. Test consists a sequence of 12 songs where each one is played during 1 minute. Songs were grouped in 4 sets based on pleasant/activation level. In this preliminary study, 6 male subjects realized...

People with autism spectrum disorder (ASD) have great difficulties in social interaction and in the management of personal and other people's emotions. This work aimed at developing an intelligent bracelet, capable of inferring the children's emotional state, transmitting it to others, and, above all, informing the patients themselves so that...

This paper describes several computer access methods tested by Eva, a woman with choreoathetosic cerebral palsy. This disease prevents her from controlling the peripherals and configurations that normally give access to information and communication technologies, further limiting her independence. To make Eva access a computer, we focused our...

This paper presents the development of a virtual rehabilitation game and mental load with different difficulty blocks. The game was controlled with body tracking and physiological signals - electrocardiography and electrodermal activity - were recorded throughout the session. Several parameters - heart rate (HR), heart rate variability (HRV),...

The analysis of cardiac activity is one of the most common elements for evaluating the state of a subject, either to control possible health risks, sports performance, stress levels, etc. This activity can be recorded using different techniques, with electrocardiogram and photoplethysmogram being the most common.
