Tactile, visual, and bimodal P300s: Could bimodal P300s boost BCI performance?

The P300 is a positive peak in EEG occurring after presentation of a target stimulus. For brain-computer interfaces (BCIs), eliciting P300s by tactile stimuli would have specific advantages; the display can be hidden under clothes and keeps the user’s gaze free. In addition, robust classification is especially important for BCIs. This motivated...

Brain controlled navigation through virtual worlds

New techniques based on brain signals aim to make navigation through virtual worlds more intuitive. GATE - Overview of activities 2007-2010 - Looking at the future of games

Perception coherence zones in flight simulation

The development and tuning of flight simulator motion filters relies on understanding human motion perception and its limitations. Of particular interest to flight simulation is the study of visual-inertial coherence zones. Coherence zones refer to combinations of visual and inertial cues that, although not being physically coherent, still...

Robots that care

Many countries face pressure on their health care systems. To alleviate this pressure, 'self care' and 'self monitoring' are often stimulated with the use of new assistive technologies. Social robotics is a research area where robotic technology is optimized for various social functions. One of these functions is self care assistance. To foster...

Adaptive Support for Human-Computer Teams: Exploring the Use of Cognitive Models of Trust and Attention

The safety of pedestrian crossing

More than half of all severe traffic accidents in which pedestrians or cyclists are involved, occur during road crossing. In this chapter insights, based on previous studies and literature, concerning requirements for safe and comfortable crossing facilities are discussed. In order to develop notions of needs, abilities and motives, different...

The Influence of Perceived Safety and Security on Walking

In the current chapter we highlight two types of risk that are of importance for pedestrians: the risk of being involved in an accident and the risk of being victim of criminal offences, violence or threats. In most cases it is the latter type of risk that is of importance for pedestrians, and which influences their behaviour. From a theoretical...

Data on mobility and safety

The urban expansion, the motorization, the work and shopping concentration in the cities outskirts have caused a constant increase in the travelling distances. Therefore, walking is getting more and more difficult and dangerous. On the other hand, there is a great diversity of pedestrians with different requests or needs when using the urban and...

Cybersickness Influences the Affective Appraisal of a Virtual Environment

We investigated if cybersickness has an effect on the affective appraisal of a virtual environment (VE). For many applications it is essential that users experience the simulated environment in a similar way as the corresponding real one. Navigation through VEs is known to negatively influence the physical well-being of observers by inducing...

Cognitive engineering for technology in mental health care and rehabilitation

The use of technology, such as virtual reality, electronic diaries, multimedia, brain computing and computer games, to support the care and rehabilitation of patients affected by mental disorders is a relatively new and advancing research area. In this workshop, researchers, developers and mental health professionals will present and discuss...

Coping under acute stress: The role of person characteristics

Effectiveness assessment of signal processing in the presence of smear

Moving imagery from a static scene was recorded with an un-cooled thermal imager at nine different angular velocities ranging from 0 (static) to 1 pixel/frame (3.75 deg/s) using a tilted rotating mirror. The scene contained a thermal acuity test chart with triangular test patterns based on the Triangle Orientation Discrimination (TOD) test...

Design and evaluation of (urban) camouflage

An international group consisting of several NATO nations participated in a trial in which urban camouflage was developed and compared. First, photographs were taken in and around a small town (arid climate). Next, the different groups derived urban camouflage patterns from these photographs. We applied our method for deriving a camouflage...

Developing a model of cognitive lockup for user interface engineering

This paper presents the development of a cognitive model of cognitive lockup: the tendency of humans to deal with disturbances sequentially, possibly overseeing crucial data from unattended resources so that serious task failures can appear—e.g., in a cockpit or control centre. The proposed model should support the design and evaluation of user...
