van Erp, J.B.F. (author), Paul, K.I. (author), Mioch, T. (author)Electronic travel aids (ETAs) can increase the safety and comfort of pedestrians who have a visual impairment by displaying obstacles through a vibrotactile navigation belt. Building a complete picture of relevant obstacles and finding a safe route requires ETA users to integrate vibrotactile cues over time and space in their tactile working...article 2020

Coffey, E.B.J. (author), Brouwer, A.M. (author), Wilschut, E.S. (author), van Erp, J.B.F. (author), TNO Defensie en Veiligheid (author)Recent advances in non-invasive brain-machine or brain-computer interfaces (BMIs/BCIs) have demonstrated that humans can control computers or simple robotic devices using only brain signals. These successes have lead to the suggestion that BMIs could significantly improve the safety and efficiency of space operations. Electroencephalography (EEG...article 2010

Philippi, T.G. (author), van Erp, J.B.F. (author), Werkhoven, P. (author), TNO Defensie en Veiligheid (author)When the presentation of a single flash is paired with that of 2 taps, a second, illusory, flash is sometimes perceived. We presented participants with 1 or 2 flashes paired with 1 or 2 taps and asked them to report the number of flashes. In experiment 1, we used the response categories 1, 2, 3 and analyzed the responses to 2 consecutive...conference paper 2010

TNO Defensie en Veiligheid (author), Brouwer, A.M. (author), van Erp, J.B.F. (author)In this study, we investigated a Brain-Computer Interface (BCI) based on EEG responses to vibro-tactile stimuli around the waist. P300 BCIs based on tactile stimuli have the advantage of not taxing the visual or auditory system and of being potentially unnoticeable to other people. A tactile BCI could be especially suitable for patients whose...article 2010

Werkhoven, P.J. (author), van Erp, J.B.F. (author), Philippi, T. (author), TNO Defensie en Veiligheid (author)Irrelevant events in one sensory modality can influence the number of events that are perceived in another modality. Previously, the underlying process of sensory integration was studied in conditions in which participants knew a priori which sensory modality was relevant and which was not. Consequently, (bottom-up) sensory interference and (top...article 2009

(author), TNO Defensie en Veiligheid (author), DenV (author)Helicopter landings are more challenging in 'brownout' conditions, in which sand and dust is stirred up by the rotary wing aircraft, obscuring visibility. Safe brownout landings require new sensor and display technologies to provide the pilot with information on helicopter motion. In this respect tactile displays are promising: The pilot can...conference paper 2008

Philippi, T. (author), van Erp, J.B.F. (author), Werkhoven, P.J. (author), TNO Defensie en Veiligheid (author)In temporal numerosity judgment, observers systematically underestimate the number of pulses. The strongest underestimations occur when stimuli are presented with a short interstimulus interval (ISI) and are stronger for vision than for audition and touch. We investigated if multisensory presentation leads to a reduction of underestimation....article 2008

Support is often based on mobile maps. People have different preferences for map orientations (heading-up or north-up), but map orientations also have different advantages and disadvantages. In general north-up maps are good for building up situation awareness and heading-up maps...conference paper 2008
