Recently brain-computer interface (BCI) control was integrated into the commercial assistive technology product QualiWORLD (QualiLife Inc., Paradiso-Lugano, CH). Usability of the first prototype was evaluated in terms of effectiveness (accuracy), efficiency (information transfer rate and subjective workload/NASA Task Load Index) and user satisfaction(More)
OBJECTIVE To evaluate the impact of a hybrid control on usability of a P300-based brain-computer interface (BCI) system that was designed to control an assistive technology software and was integrated with an electromyographic channel for error correction. DESIGN Proof-of-principle study with a convenience sample. SETTING Neurologic rehabilitation(More)
Albeit research on brain-computer interfaces (BCI) for controlling applications has expanded tremendously, we still face a translational gap when bringing BCI to end-users. To bridge this gap, we adapted the user-centered design (UCD) to BCI research and development which implies a shift from focusing on single aspects, such as accuracy and information(More)
OBJECTIVE While brain-computer interfaces (BCIs) for communication have reached considerable technical maturity, there is still a great need for state-of-the-art evaluation by the end-users outside laboratory environments. To achieve this primary objective, it is necessary to augment a BCI with a series of components that allow end-users to type text(More)
— This paper presents an important step forward towards increasing the independence of people with severe motor disabilities, by using brain-computer interfaces (BCI) to harness the power of the Internet of Things. We analyze the stability of brain signals as end-users with motor disabilities progress from performing simple standard on-screen training tasks(More)
OBJECTIVE To describe experience of assistive technology service delivery (ATSD) by parents of children with physical or multiple disabilities (aged 3-18 years). METHOD Forty-seven of 115 parents participated in a postal survey assessing satisfaction with the ATSD process, employing the QUEST 2.0 and the KWAZO scales. Six of these participated in two(More)
There is a lack of evidence on the effects and quality of assistive technology service delivery (ATSD). This study presents a quasi-experimental 3-months follow-up using a pre-test/post-test design aimed at evaluating outcomes of assistive technology (AT) interventions targeting children with physical and multiple disabilities. A secondary aim was to(More)
Clinical applications of speech technology face two challenges. The first is data sparsity. There is little data available to underpin techniques which are based on machine learning and, because it is difficult to collect disordered speech corpora, the only way to address this problem is by pooling what is produced from systems which are already in use. The(More)
An investigation was carried out to identify the fish parasites in the Chiascio River (Umbria, Italy). Certain physical-chemical factors and the biochemical oxygen demand of the river water were, also, studied in samples taken seasonally. The parasites found, together with the fish species they invested and the organs and apparatuses involved, are listed.(More)
An investigation was carried out to identify the actual state of parasitism in the Tinca tinca population of Trasimeno lake (Umbria, Italy). It has been found: a high number of infested specimens, eleven species of parasites, of which four were not yet known to be in the lake, frequency variations of certain species, the absence of others that in the past(More)
