Abstract:

Sound of Vision designed, implemented and validated an original non-invasive hardware and software system to assist visually impaired people by creating and conveying an auditory representation of the surrounding environment.

This representation is created, updated and delivered to a blind person continuously and in real time.

This system helps visually impaired people in any kind of environment (indoor/outdoor), without the need for predefined tags/sensors located in the surroundings.

Abstract:

TRAVEE (Virtual Therapist with Augmented Feedback for Neuromotor Recovery) will design, implement and validate an original and affordable IT system for recovery of patients with neuromotor impairments following strokes, traumas or brain surgery.

Stroke is the leading cause of long term disability in modern societies, with huge economical and social implications. Growing life expectancy accentuates the issues, leading to impossibility of decent care and rehab based only on human therapists. In this context, IT care and recovery solutions are of utmost importance for core functioning of modern societies.

TRAVEE relies on a brand new idea - recovery through augmented feedback - that creates new, distinct possibilities to overcome block stages typical to early recovery.

Neuromotor recovery relies on neuroplasticity (generic term covering various adaptive modifications of the cortex). The causal chain specific to recovery includes:

- motor act is performed or attempted, by the patient, with or without external help;

- patient observes sensations and results (visually, haptic or proprioceptive);

- patient's cortex associate the motor act with the observations and gradually learns and perfects the motor act.

Most techniques and systems for neuromotor recovery only pay attention to the motor act performance, neglecting the essentiality of observation. We consider that their limited success is due exactly to this conceptual simplification. TRAVEE brings a solution to handle the whole recovery causal chain, in a unified way. Its implementation will improve the number of recovery cases, the average recovery degrees and time, with major socio-economic impact.

To harness the potential of this idea, TRAVEE will employ modern technologies: virtual reality, robotics, BCI, EMG, FES, telemedicine, etc.

A patient's 3D virtual body model (VBM) will aggregate data from sensors for position, movement, central & peripheral nervous activity. VBM will be updated in real time and rendered to the patient on a screen or video glasses.

A therapy session consists in a task being given to the patient, his attempts to perform it and assistance from the system in various ways (augmented feedback, robotic support, functional electric stimulation, etc.) - based on a preconfigured program or under direct therapist's control.

Unlike robotics or FES, which are encountered in many approaches, feedback augmentation is an innovative feature of TRAVEE, consisting in its capacity to alter the representation of the VBM to allow the observation of modifications otherwise unobservable by the patient (e.g. very small moves can be represented enlarged to a degree that makes them perceivable by the patient; detected failed intentions of movement can be represented as small moves). In this way, the causal loop can be closed, avoiding blocking of recovery.

TRAVEE will develop also innovative methods for communicating with the target patients, one being its presentation as a virtual therapist, a concept new in this field, backed up by the medical specialists from the consortium, attractive and stimulating for the patients.

This project will develop a fully functional prototype and a library of training programs dedicated to early stages of recovery and validate them on a large number of patients. The prototype with the library will be submitted to the procedure for medical certification and subsequently commercialized as a package including hardware, software and medical procedures.

TRAVEE will embody in an affordable system, easy to install and use - in dedicated facilities or at homes (independent or through telemedicine).

The Consortium has a multi-disciplinary structure, with all essential complementary competencies required for the conception and development of TRAVEE as IT, medical and commercial system. TRAVEE is an original concept, with potential to turn into an affordable product improving neuromotor rehab, with exceptional socio-economic impact.

AN INTELLIGENT HAPTIC ROBOT GLOVE for the PATIENTS SUFFERING A CEREBROVASCULAR ACCIDENT Call name: Joint Applied Research Projects - PCCA-2011 call, Type 1

Abstract:

In the last decade, the scientific community has become increasingly interested in so-called Rehabilitation Robotics, a branch of the areas of Robotics and Mechatronics that addresses to the study of complex robotic systems aimed at the restoration of human functions for those people who haved suffered major trauma as a result of strokes and cerebrovascular diseases. A cerebrovascular stroke occurs when a blood vessel (an artery) that supplies blood to an area of the brain bursts or is clogged by a blood clot. As a result, the part of the body that is controlled by the affected area of the brain cannot function properly.Total loss or loss of range of motion, decreased reaction times and disordered movement organization create deficits in motor control, which affect the patient’s independent living.A key feature of our project is that subjects at any impairment level can repetitively practice and complete stereotyped movement patterns. Active retraining can positively shape the cortical reorganization associated with motor recovery following brain injury. This therapy involves intensive repetitive exercise of the more affected limb coupled with constraint of the opposite limb and results in positive cortical reorganization in the motor cortex.

This project deals with the design and development of an Intelligent Haptic Robot-Glove (IHRG) for the rehabilitation of the patients that have a diagnosis of a cerebrovascular accident (CVA).The IHRG is an exoskeleton that supports human hand and hand activities by using a control and virtual architecture for dexterous grasping and manipulation. This IHRG is a medical device that acts in parallell to a hand in order to compensate some lost function. In this project, a novel mechatronic approach for the development of an exoskeleton assistive hand is considered, integrating the mechanical structure, the sensory , the actuation system and the virtual and control system.

Abstract:

The project proposes to redefine the relationship between art and science for a new, 21st century paradigm.

The project intends to reconstruct the memory of forgotten places, which will be shared with the local community and with virtual communities as well, thus helping preserve and safeguard the material and immaterial heritage.

We propose a new utilization of the mixed reality in urban and rural contexts by creating new mental maps, which will model human perception.

A Map of Time would be the memory of all the invisible places, of objects and gestures forgotten; it would be a Virtual World recovered. For every discovered location we intend to offer overlapped layers of information, to be accessed in the manner of an archaeological stratigraphy. Every user will explore and integrate in the overlapped Virtual Worlds at different reconstructed chronological levels.

The Maps of Time will help first their makers to recover the humane message of the Past, and later will help contemporary communities to redefine their identity.

One of the project’s important benefits and novel aspects is its beneficial social implications for the communities participating in it. A social aspect will be the creation of a cyberculture which will help the invisible rural communities to create their own virtual museums to promote their own identity and to develop a participatory tourism.
