Several studies have explored brain computer interface (BCI) systems based on auditory stimuli, which could help patients with visual impairments. Usability and user satisfaction are important considerations in any BCI. Although background music can influence emotion and performance in other task environments, and many users may wish to listen to music while using a BCI, auditory, and other BCI...

Most Brain-Computer Interfaces (BCI) are based on machine learning and behave like black boxes, i.e., they cannot be interpreted. However, designing interpretable BCI would enable to discuss, verify or improve what the BCI has automatically learnt from brain signals, or possibly gain new insights about the brain. In this paper, we present an algorithm to design a fully interpretable BCI. It can...

This paper presents a virtual reality brain computer interface (BCI) system which allows the user to interact physical objects in the ubiquitous home. The system is designed for motion disabled people to control real home facilities by a simple motor imagery and minimal physical body movements. While BCI research has mostly focused on improving classification algorithm, our BCI system uses a si...

مقدمه: بازشناسی فعالیت‌های مختلف حسی- حرکتی در سامانه‌های واسط مغز و رایانه با مباحث بازشناسی الگو در ارتباط است. یکی از مسائل مهم در طراحی یک سامانه مؤثر واسط مغز و رایانه، چگونگی کاهش تعداد ویژگی‌های استخراج شده از سیگنال‌های مغزی است. استفاده از الگوریتم‌های انتخاب ویژگی یکی از مهم‌ترین مراحل در زمینه بازشناسی الگو می‌باشد. کاهش تعداد ویژگی‌ها می‌تواند در بهبود دقت و کارایی طبقه‌بند‌ها و در ...

PURPOSE Previous results from the TransATAC study demonstrated that both the Breast Cancer Index (BCI) and the OncotypeDX Recurrence Score (RS) added significant prognostic information to clinicopathologic factors over a 10-year period. Here, we examined cross-stratification between BCI and RS to directly compare their prognostic accuracy at the individual patient level. EXPERIMENTAL DESIGN A...

Modulation of sensorimotor rhythms (SMR) was suggested as a control signal for brain-computer interfaces (BCI). Yet, there is a population of users estimated between 10 to 50% not able to achieve reliable control and only about 20% of users achieve high (80-100%) performance. Predicting performance prior to BCI use would facilitate selection of the most feasible system for an individual, thus c...

In the last years Brain Computer Interface (BCI) technology has benefited from the development of sophisticated machine leaning methods that let the user operate the BCI after a few trials of calibration. One remarkable example is the recent development of co-adaptive techniques that proved to extend the use of BCIs also to people not able to achieve successful control with the standard BCI pro...

A brain-computer interface (BCI) is a device that enables severely disabled people to communicate and interact with their environments using their brain waves. Most research investigating BCI in humans have used scalp-recorded electroencephalography (EEG). We have recently demonstrated that signals from intracranial electrocorticography (ECoG) and stereotactic depth electrodes (SDE) in the hipp...

Brain Computer Interface (BCI) systems have gained great visibility in the last years for the possibility they give to severly disabled people to have a normal interaction with the external environment. However every group implements its own BCI system and this leads to a lack of a common language concerning methods, names of BCI components, file formats, tools etc..., with an obvious difficult...

The idea of robotic therapy has been considered as a possible rehabilitation strategy to facilitate recovery the patients with disability and it can represent an efficient treatment. Brain-computer interface (BCI) is known advanced technology great potential in therapeutic assistive robots. This paper presented review application BCI systems through combination electroencephalography (EEG) func...
