In recent years, the need to address the multi-faceted issue of AI governance with safety-relevant, ethical and legal implications at an international level is becoming increasingly itical. Simultaneously, the international community is facing a wide array of global challenges for which the United Nations initiated an agenda with 17 ambitious...

The complex socio-technological debate underlying safetycritical and ethically relevant issues pertaining to AI development and deployment extends across heterogeneous research subfields and involves in part conflicting positions. In this context, it seems expedient to generate a minimalistic joint transdisciplinary basis disambiguating the...

Presence and the sense of embodiment are essential concepts for the experience of our self and virtual bodies, but there is little quantitative evidence for a relation between these, and this relation becomes more complicated when there are real and virtual bodies in augmented reality (AR). We investigate the experience of body ownership, agency...

Steady progresses in the AI field create enriching possibilities for society while simultaneously posing new complex challenges of ethical, legal and safety-relevant nature. In order to achieve an efficient human-centered governance of artificial intelligent systems, it has been proposed to harness augmented utilitarianism (AU), a novel non...

Researchers have reported that audiovisual object presentation improves memory encoding of object identity in comparison to either auditory or visual object presentation. However, multisensory memory effects on retrieval, on object location, and of other multisensory combinations are yet unknown. We investigated the effects of visuotactile...

Gaze-independent event-related potential (ERP) based brain-computer interfaces (BCIs) yield relatively low BCI performance and traditionally employ unimodal stimuli. Bimodal ERP-BCIs may increase BCI performance due to multisensory integration or summation in the brain. An additional advantage of bimodal BCIs may be that the user can choose...

The brain is able to determine angular self-motion from visual, vestibular, and kinesthetic information. There is compelling evidence that both humans and non-human primates integrate visual and inertial (i.e., vestibular and kinesthetic) information in a statistically optimal fashion when discriminating heading direction. In the present study,...

When using brain–computer interfaces (BCIs) to control a game, the BCI may have to compete with gaming tasks for the same perceptual and cognitive resources.We investigated: 1) if and to what extent event-related potentials (ERPs) and ERP–BCI performance are affected in a dual-task situation; and 2) if these effects are an area function of the...

This chapter discusses mechanisms of multimodal perception in the context of multimodal simulators and virtual worlds. We review some notable findings from psychophysical experiments with a focus on what we call touch-inclusive multimodal perception—that is, the sensory integration of the tactile system with other sensory systems such as vision...

Event-related potential (ERP) based brain-computer interfaces (BCIs) employ differences in brain responses to attended and ignored stimuli. When using a tactile ERP-BCI for navigation, mapping is required between navigation directions on a visual display and unambiguously corresponding tactile stimuli (tactors) from a tactile control device:...

Although the mechanisms of neural adaptation to weightlessness and re-adaptation to Earth-gravity have received a lot of attention since the first human space flight, there is as yet little knowledge about how spatial orientation is affected by partial gravity, such as lunar gravity of 0.16. g or Martian gravity of 0.38. g. Up to now twelve...

Event-related potential (ERP)-based brain–computer interfaces (BCIs) employ differences in brain responses to attended and ignored stimuli. Typically, visual stimuli are used. Tactile stimuli have recently been suggested as a gaze-independent alternative. Bimodal stimuli could evoke additional brain activity due to multisensory integration which...

The development of Brain Computer Interfaces (BCIs) enters a phase in which these devices are no longer restricted to applications in controlled, single-task environments. For instance, BCIs for gaming or high-end operator stations will function as part of a multimodal user interface in a multitask environment. This phase introduces new issues...

In this study, the authors investigated how restriction of the vertical viewing angle influences obstacle-crossing behavior. Twelve participants stepped over obstacles of different dimensions while wearing visual-field-restricting goggles. Using full-body motion capture, several kinematic measures were extracted and analyzed. Results indicate...

This study investigated how human locomotion through an obstacle environment is influenced by visual field limitation. Participants were asked to walk at a comfortable pace to a target location while avoiding multiple vertical objects. During this task, they wore goggles restricting their visual field to small (S: 40° × 25°), medium (M: 80° × 60...

Abstract In this chapter we discuss Brain-Computer Interfaces (BCIs) as navigation devices from a Human Factors point of view. We argue that navigation is more than only steering a car or a wheelchair. It involves three levels: planning, steering and control, linked to cognition, perception and sensation, respectively. We structure the existing...

Knowledge of human motion perception can be applied in the optimization of motion cueing algorithms. In the past it has been shown that some discrepancies between the amplitude or phase of a visual and inertial cue go unnoticed. These acceptable discrepancies are referred to as coherence zones. In the present experiment we investigate whether a...

In the present study, we investigated whether the perception of heading of linear self-motion can be explained by Maximum Likelihood Integration (MLI) of visual and non-visual sensory cues. MLI predicts smaller variance for multisensory judgments compared to unisensory judgments. Nine participants were exposed to visual, inertial, or visual...
