This paper presents an extensible distributed platform that aims to speed up the development of personalized telemedicine systems, dealing with a series of recurrent problems in this kind of system, particularly: (1) functionality encapsulation and reuse in a set of services; (2) communications between the patient's home and the hospital, through a flexible scheme for bidirectional message exchange;...
We present a wearable sensor platform designed for monitoring and studying autonomic nervous system (ANS) activity for the purpose of mental health treatment and interventions. The mobile sensor system consists of a sensor band worn on the ankle that continuously monitors electrodermal activity (EDA), 3-axis acceleration, and temperature. A custom-designed ECG heart monitor worn on the chest is also...
Electrocardiograms and other similar techniques (e.g. Photoplethysmograph) are very effective tools for the detection of cardiac abnormalities. Automated analyses of ECG signals may be used for this purpose, but due to their complexity — often involving a Neural Network or Principal Component Analysis — the signal needs to be transmitted to be analysed on a powerful device. Thus, even if signals are...
In order to keep a healthy body it is very important to have balanced energy expenditure (EE). The proposed system utilized the phonocardiogram (PCG) and motion from the user to generate the heart rate. The heart rate has been deemed as a very reliable index to estimate the EE of human body. Efforts are put on developing our system to deal the situations when severe interference coupled into the system...
In this study, we proposed new self assessment of hearing loss in mobile phones and realized a function of compensation for hearing impaired person. The results of experiments on mobile phone showed that the proposed hearing test is sufficient to check hearing loss and the compensation based on the result of the proposed hearing test can improve speech intelligibility of hearing impaired persons.
Regular retinal examinations can contribute to the management of both hypertensive and diabetic retinopathy. One of the most successful means of evaluating these retinopathies is by means of a fundus camera generating a fundus photograph. Patients in rural clinics unfortunately often lack the financial means to undergo regular examinations. This study produced a handheld ophthalmoscope that combines...
We have developed a new mobile phone-based safety support system for transmitting information of a wandering elderly person's location and the environmental sounds around that person. The system consists of a wearable sensor and a conventional desktop PC with Internet access acting as the server computer. The wearable sensor, which is attached behind the neck of the elderly person's shirt, is composed...
Mobile health monitoring in the management of long term conditions has potential benefits for patient care, especially when coupled with active adjustment of medication dosage. We report studies of patient-led self-titration of oral glucose lowering medication (OGLM) and insulin in type 2 diabetes, and dose adjustments (including dose increases) in oral chemotherapy for metastatic colorectal or breast...
In the development of technology for people with mild dementia it is essential to achieve a combination of the features which provide both support and monitoring along with the ability to offer a level of personalization. Reminding support by means of personalized video reminders portraying a relative or friend combined with sensors to assess whether the requested task was performed lends itself as...
This paper describes the motivation for, and overarching design of, an open-source hardware and software system to enable population-scale, longitudinal measurement of physical activity and sedentary behavior using common mobile phones. The “Wockets” data collection system permits researchers to collect raw motion data from participants who wear multiple small, comfortable sensors for 24 hours per...
Many well-known brain-computer interfaces measure signals at the brain, and then rely on the brain's ability to learn via operant conditioning in order to control objects in the environment. In our lab, we have been developing brain-muscle-computer interfaces, which measure signals at a single muscle and then rely on the brain's ability to learn neuromuscular skills via operant conditioning. Here,...
A daily living activity remote monitoring system has been developed for supporting solitary elderly people. The monitoring system consists of a tri-axis accelerometer, six low-power active filters, a low-power 8-bit microcontroller (MC), a 1GB SD memory card (SDMC) and a 2.4 GHz low transmitting power mobile phone (PHS). The tri-axis accelerometer attached to the subject's chest can simultaneously...
