Use of Inertial Measurement Units for short and long-term physical activity monitoring

| 16h00 - 16h45 GMT


In recent years there has been an increased interest in monitoring people of all ages. This increase has been particularly noticeable in the use of wearable devices, such as smart watches or activity bracelets, which provide information on steps, distance travelled, calories consumed, physiological parameters, etc. With the increase in life expectancy, the need to design devices and applications for monitoring the health of the older adults emerges with different objectives, as to provide telecare assistance, to improve their quality of life as well as to keep their independence. Currently, many studies propose to perform physical tests of elderly people using inertial measurement units (IMUs) placed on different parts of the body, in order to provide information about physical activity (PA) for the frailty assessment. However, these tests are usually of short duration, and often do not provide objective information on the PA of the person.
This talk is intended to show the use of the IMUs for physical activity monitoring, but not only for short duration tests, but also for long-term analysis that provides a better and more objective information on person’s PA. As IMUs can provide information about positioning, this webinar will also cover the advantages of fusing the positioning with PA, in order to obtain people routines.

Applied Machine Learning for Wearable and Remote Sensors

| 16h45 - 17h30 GMT


Machine learning has emerged as an advanced powerful data processing tool and is currently becoming the core of sensor development. With the demand for continuous monitoring steadily increasing, IoT sensors have sprung up in various forms. Machine learning has been aiding us to make meaningful decisions out of these sensed data. In this talk, the application of machine learning for wearable and remote sensors will be considered with emphasis on handling data. Two main trends of data handling will be discussed in this speech. First, compressive techniques will be explored to compress the data, and then machine learning in the compressed domain can be investigated. For example, sensors used for monitoring arrhythmia produce a lot of data. Second, deep learning techniques for sensing falls- acquired by remote and wearable sensors- will be discussed. In areas such as fall monitoring, there is no adequate amount of data to train a deep model. Therefore, few-shot learning approaches for learning from limited data will also be considered in this talk.
