In this paper we give an outline of the ground course on spatial disorientation that TNO Human Factor provides for military student aviators of the Royal Netherlands Airforce. During this one-day course a variety of laboratory equipment is used to let students experience and understand different disorienting phenomena and to make them aware of...

We here present a model including visual-vestibular interactions describing the basic properties of the human spatial orientation system. It hence also explains and describes spatial disorientation. The model indicates that spatial orientation should at least be characterised by four variables: linear acceleration and velocity, angular velocity,...

The degraded visual infoflllation when hovering with Night Vision Goggles may induce drift that is not noticed by the pilot. We tested the possibilities of counteracting these effects by using a tactile torso display. The display consisted of 64 vibro-tactile elements and presented infoflllation on the desired direction of motion only (simple...

We examined to what extent body tilt may augment the perception of visually simulated linear self acceleration. Fourteen subjects judged visual motion profiles of fore-aft motion at four different frequencies between 0.04-0.33 Hz, and at three different acceleration amplitudes (0.44, 0.88 and 1.76 m/s2). Simultaneously, subjects were tilted...

In 2002 my colleague and friend Alex Wertheim went into early retirement. He continued his professorship at the University of Utrecht, but left TNO Human Factors in December. At his sooner than expected farewell party I expressed my desire to offer him one more get-together, but now with insiders in the area of his main scientific interest: the...

Pilot perception models include detailed descriptions of the sensory dynamics involved in human spatial orientation. For example, the TNO Spatial Orientation model contains transfer functions of the visual and vestibular system (semicircular canals and otoliths). In our previous attempts to apply this model for the validation of simulator motion...

Tactile displays provide information by applying local vibrations to the user's skin. The research organization TNO has developed a tactile torso display by implementing a number of pager motors, or “tactors” into a vest, allowing for the generation of spatio-temporal patterns. TNO carries out research into the usefulness of this tactile torso...

Unsuccessful recovery from unusual flight attitudes, or “airplane upset”, is considered an important factor in civil aviation accidents. It is generally recognized that there is a clear need for enhanced training of recovery procedures from unusual flight attitudes, i.e. situations where an aircraft unintentionally exceeds the parameters of the...
