We examined to what extent we can distinguish between ‘real-life’ stressed and relaxed participants on the basis of heart rate (HR), heart rate variability (HRV) and skin conductance level (SCL) as measured during rest. Physiological and subjective measures were compared between individuals that were to undergo eye laser surgery and a control...

Firefighters searching for victims work in hazardous environments with limited visibility, obstacles and uncertain navigation paths. In rescue tasks, extra sensor information from infrared cameras, indoor radar and gas sensors could improve vision, orientation and navigation. A visual and tactile interface concept is proposed that integrates...

The TTP (Targeting Task Performance) metric, developed at NVESD, is the current standard US Army model to predict EO/IR Target Acquisition performance. This model however does not have a corresponding lab or field test to empirically assess the performance of a camera system. The TOD (Triangle Orientation Discrimination) method, developed at TNO...

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...

Compared to standard earplugs used for hearing protection, electronic pass-through earplugs provide better sound localisation, provided that the bandwidth is sufficiently wide and the earplugs do not change the shape of the pinnae. However, when in addition a helmet is worn that covers the ears, the directional hearing capability might be...

We developed a software framework for image-based simulation models in the chain: scene-atmosphere-sensor-image enhancement-display-human observer: EO-VISTA. The goal is to visualize the steps and to quantify (Target Acquisition) task performance. EO-VISTA provides an excellent means to systematically determine the effects of certain factors on...

Introduction: Recent evidence indicates that vibrotactile displays can potentially reduce the risk of sensory and cognitive overload. Before these displays can be introduced in super agile aircraft, it must be ascertained that vibratory stimuli can be sensed and interpreted by pilots subjected to high G loads. Methods: Each of 9 pilots...

We conducted an experiment to explore the relation between facial temperature and mental effort. Participants had to perform mentally demanding tasks while their face was captured with an infrared camera. The temperature of the nose decreased during these tasks and increased during the successive rest blocks. Other parts of the face did not...

A spatial electrocutaneous display for sensory substitution is being designed. The display will be used to feed back sensory signals from transfemoral prostheses to amputees. The aim is to improve their walking performance. Two experiments have been performed to optimise the display parameters for dynamic, cyclic signals, which are common during...
