Brain-computer interfaces (BCIs) can serve as muscle independent communication aids. Persons, who are unable to control their eye muscles (e.g. in the completely locked-in state) or have severe visual impairments for other reasons, need BCI systems that do not rely on modality. For this reason, BCIs employ auditory stimuli were suggested. In study, a multiclass spelling system was implemented uses animal voices with directional cues code rows and columns of letter matrix. To reveal possible...
Abstract Background The rehabilitation of gait disorders in patients with multiple sclerosis (MS) and stroke is often based on conventional treadmill training. Virtual reality (VR)-based training can increase motivation improve therapy outcomes. present study evaluated an immersive virtual application (using a head-mounted display, HMD) for to (1) demonstrate its feasibility acceptance (2) compare short-term effects semi-immersive presentation monitor) without VR assess the usability both...
Virtual Reality (VR) technology offers promising opportunities to improve traditional treadmill-based rehabilitation programs. We present an immersive VR system that includes a head-mounted display and motion sensors. The application is designed promote the experience of relatedness, autonomy, competence. uses procedural content generation generate diverse landscapes. evaluated effect on motivation affect. conducted repeated measures study with 36 healthy participants compare program...
In an EEG-based near real-time neurofeedback (NF) study in two parts using high immersive virtual reality (VR) we successfully trained healthy participants to downregulate their parietal alpha power, a neurophysiological correlate previously associated with enhanced sense of presence. The first part included n = 10 equipped 128 and 64 channels gel-based active EEG electrodes sessions standard bar feedback presented on computer monitor. Nine were better than random at the 10th session four...
In this study, we evaluated electrooculography (EOG), an eye tracker and auditory brain-computer interface (BCI) as access methods to augmentative alternative communication (AAC). The participant of the study has been in locked-in state (LIS) for 6 years due amyotrophic lateral sclerosis. He was able communicate with slow residual movements, but had no means partner independent communication. We discuss usability all tested prospects using BCIs assistive technology.Within four days, whether...
Visual ERP (P300) based brain-computer interfaces (BCIs) allow for fast and reliable spelling are intended as a muscle-independent communication channel people with severe paralysis. However, they require the presentation of visual stimuli in field view user. A head mounted display could convenient situations, where mounting conventional monitor might be difficult or not feasible (e.g. at patient's bedside). To explore if similar accuracies can achieved virtual reality (VR) headset compared...
Virtual humans, including virtual agents and avatars, play an increasingly important role as VR technology advances. For example, humans are used digital bodies of users in social or interfaces for AI assistants online financing. Interpersonal trust is essential prerequisite real-life interactions, well the world. However, to date, there no established interpersonal measurement tools specifically reality. This study fills gap, by contributing a novel validated behavioural tool measure...
Current brain-computer interface software is often tailored to the needs of scientists and technicians therefore complex allow for versatile use. To facilitate home use interfaces (BCIs) a multifunctional P300 BCI with graphical user intended non-expert set-up control was designed implemented. The system includes applications spelling, web access, entertainment, artistic expression environmental control. In addition new software, it also hardware recording electroencephalogram (EEG) signals....
Abstract Objective Videoconferencing psychotherapy (VCT) is an effective treatment option. Yet, it unclear whether a similar therapeutic alliance as in conventional face‐to‐face (F2F) can be achieved, since previous studies yielded mixed results. Furthermore, surveys about the attitudes towards VCT amongst patients have been missing until now. The current study gathered opinions from and psychotherapists perceived comparability of F2F regarding contextual factors characteristics, focusing on...
The patient-physician relationship is essential for treatment success. Previous studies demonstrated that physicians who behave empathic in their interaction with patients have a positive effect on health outcomes. In this study, we investigated if the mere perception of as empathic/not modulates pain despite an emotionally neutral patients.N = 60 women took part experimental study simulated clinical interaction. paradigm, each participant watched two immersive 360° videos via head-mounted...
Abstract Immersive virtual reality is a powerful method to modify the environment and thereby influence experience. The present study used hand illusion context manipulation in immersive examine top-down modulation of pain. Participants received painful heat stimuli on their forearm placed an embodied (co-located with real one) under water tap, which dispensed different experimental conditions. We aimed induce temperature by red, blue or white light suggesting warm, cold no water. In...
Humans show a robust tendency to look at faces in images, but also differ consistently the strength of this attentional preference. Previous research remained inconclusive as how stronger face preference may be indicative an individual's personality or clinical characteristics. Here we investigated preferences 120 participants (primarily drawn from student population) who freely viewed photos internet browser showing person context visually rich environment while attention was assessed using...
Brain-computer interface (BCI) users can control very complex applications such as multimedia players or even web browsers. Therefore, different biosignal acquisition systems are available to noninvasively measure the electrical activity of brain, electroencephalogram (EEG). To make BCIs more practical, hardware and software nowadays designed user centered friendly. In this paper we evaluated one latest innovations in area BCI: A wireless EEG amplifier with dry electrode technology combined...
