LESIM designed and implemented a motion tracking system relying on wearable Body Area Sensor Network (BASN) technology that can be deployed in domestic environment as easily as on sports ground, thanks to wireless transmission that doesn't constrain the subject's mobility: the patient can keep doing their daily activities while being treated with home rehabilitation therapies, the athlete can monitor (not affecting) their performance during practise. As well as being battery-embedded requiring no bulky battery pack and wire running along the body, sensor nodes are as small as it takes to assure no impact on performance.

Sensed data are collected and delivered by a small gateway, and, once processed, they allow trainers, therapists or the subjects themselves to watch “live” or delayed playback of the whole motor behavior from their workstations. By means of this system, measurements are made available both for real-time and offline purposes, such that analysts can be assisted in their work and take advantage of the possibility to reason about objective and comparable quantities.

Given an articulation to monitor, both of the involved limb segments are provided with a sensor node, mounted with an inertial/magnetic measurement unit: 3-axis accelerometer sensing linear acceleration, 3-axis gyroscope measuring angular rates, and 3-axis magnetometer intended to sense the Earth magnetic field.

Unlike those that keep track of how much activity one has, the designed system allows to assess complex motor skills by monitoring the whole-body motion. Analysts can watch “live” or delayed playback, augmented with related real-time measures. Once the motion of all single joints of interest has been captured, the system evaluates the action resulting from combined movements. For instance, it can assess the motion smoothness of ankles, knees, hips, wrists, elbows and shoulders for a tennis player during a downswing, in order to provide helpful hints on what body parts to focus workout on for improving their serve.

The system is quickly deliverable on the pitch or at home as the sensors are capable to detect automatically how they are being worn. As a consequence, setup is easy and requires no assistance from anyone else: athletes can be trainer-independent as they are free to put sensors on by themselves and go play. At the end of the session, captured performance is there to be analyzed.

Measurements obtained under dynamic conditions have been validated versus those resulting from commercial solutions, specifically designed for assisting motor dysfunction treatment at specialized rehabilitation centers.

Luca De Vito, assistant professor of the Department of Engineering of the University of Sannio received from IEEE a $ 10,000 award for the proposal of a course on measurements for drones.


In Turin, during the 2017 International Instrumentation and Measurement Technology Conference, Luca De Vito, assistant professor of the Department of Engineering of the University of Sannio, received the Faculty Course Development Award (http://ieee-ims.org/awards/faculty-course-development-award) of the IEEE Instrumentation and Measurement Society.

The IEEE, which stands for Institute of Electrical and Electronic Engineers (www.ieee.org), is the world greatest professional association in the field of Electrical and Electronic Engineering.

Within IEEE, the Instrumentation and Measurement Society (IMS) (www.ims.ieee.org) is dedicated to the development and use of electrical and electronic instruments and equipment to measure, monitor and/or record physical phenomena.

The IMS Faculty Course Development Award, consisting of a $ 10,000 grant was established to support and encourage faculty members to develop a new course or significantly revise an existing course with specific focus on Instrumentation and/or Measurement.

The awarded proposal describes the contents of a course titled “Drone for measurement and measurement for drone”, dedicated to the measurement technologies for the drone usage, to be delivered to the students of the PhD degree in Information technologies for Engineering.

 

Luca De Vito, ricercatore del Dipartimento di Ingegneria dell’Università del Sannio, riceve dalla IEEE un premio di $ 10000 per la proposta di un corso di misure sui droni.
