Recent developments in smart assistants and home automation are lately attracting the interest curiosity of consumers researchers. Speech enabled virtual (often named speakers) offer a wide variety network-oriented services and, some cases, can connect to environments, thus enhancing them with new effective user interfaces. However, such devices also reveal needs weaknesses. In particular, they represent faceless blind assistants, unable show face, therefore an emotion, `see' user. As...

In the attempt to mitigate effects of COVID-19 lockdown, most countries have recently authorized and promoted adoption e-learning remote teaching technologies, often with support teleconferencing platforms.

The aim of this study is to compare the performances patients with Rett syndrome that were undergoing advanced telerehabilitation (ATR) and basic (BTR). It was hypothesized ATR training would have better improvement in nearly all motor cognitive scale scoring activities administered, thus showing reduced disability. A total 20 young girls women a diagnosis RTT, ranging from age 4 31 years old (Median: 12.50; IQR: 9.50-17.25) underwent pre-test, treatment post-test 1, treatment, 2 procedure....

We propose an edge-based segmentation algorithm built on a new type of active contour which is fast, has low computational complexity and does not introduce unwanted smoothing the retrieved contours. The contours are always returned as closed chains points, resulting in very useful base for subsequent shape representation techniques.

Abstract Objective: Several studies agree on the link between attention and eye movements during reading. It has been well established that working memory (WM) interact. A question could be addressed to better understand these relationships is: what extent can an deficit affect and, consequently, remembering a word? The main aims of present study were (1) compare visual patterns word stimuli children with Attention Deficit Hyperactivity Disorder (ADHD) typically developing (TD) children,...

Telerehabilitation (TR) has been proven to be an effective tool in improving the adaptive skills of children and young adults with Multiple Disabilities (MDs). The application a comprehensive set new technologies reveals opportunities for both physical cognitive telerehabilitation, but there is no holistic approach case genetic syndromes. In this paper we present reflections early results TCTRS project that aims at implementing telerehabilitation system capable offering complete coverage...

The purpose of this study is to assess the efficacy and tolerability a new vision-based non-intrusive eye tracker in population composed normal controls patients affected by nonadvanced Parkinson's disease (PD). PD characteristically have difficulty sustaining repetitive motor actions. Previous studies showed progressive bradykinesia hypokinesia pursuit ocular movements (POM) advanced PD. We found that values POM were lower than (p < 0.001). In patients, correlated closely with Hoehn Yahr...

Face recognition represents an appealing solution for biometrics-based unobtrusive and flexible person authentication. However, most solutions proposed in the literature suffer from some significant drawbacks, such as high computational complexity, need a centralized biometrics database (which is not desirable due to widespread international provisions discouraging collections of sensitive personal data), limited scalability on large number enrolled subjects. We propose novel authentication...

Reliable detection and tracking of eyes is an important requirement for attentive user interfaces. In this paper, we present innovative approach to the problem eye tracking. A number traditional detectors, chosen their own properties, are combined by two different competitive schemes with aim obtain a higher degree robustness reliability. To illustrate our work validate combination approach, introduce proof-of-concept single-camera remote tracker discuss its implementation produced...

Remote patient monitoring can improve the quality of life elderly and impaired people, while reducing costs. Among most interesting technologies being investigated, computer vision has proved to be very effective in several important scenarios which conventional sensors fail or are impractical. We propose a vision-based wireless sensor system for people remote tracking based on low-cost embedded systems able visually track detect critical motion posture patterns, associated with dangerous...

Background: The closure of all educational institutions and most rehabilitation centres represents a precautionary measure to face the COVID-19 pandemic, but isolation social distancing may be particularly challenging for children with special needs disabilities (SEND), such as Rett Syndrome (RTT). main aim this study was promote cognitive interactions among RTT through an interactive school program. Methods: Interactive School palimpsest composed moments in which teacher spoke directly...

Recent developments in the manufacturing and marketing of low power-consumption computers, small enough to be "worn" by users remain almost invisible, have reintroduced problem overcoming outdated paradigm human-computer interaction based on use a keyboard mouse. Approaches visual tracking seem most promising, as they do not require any additional devices (gloves, etc.) can implemented with off-the-shelf such webcams. Unfortunately, extremely variable lighting conditions high degree...
