New technologies have led to an increasingly sedentary lifestyle. Sedentary behaviour is characterised by physical inactivity and is associated with several health risks. This excessive sitting does not only take place in the office or at home, but also during daily commute. Therefore, BMW AG developed an active seating system for the back seat...

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...

Data show that spatial orientation in microgravity differs from that on Earth possibly facilitating space motion sickness and degrading performance. As a technology demonstration, we developed a Tactile Orientation Awareness Support Tool (TOAST) consisting of a vest with 56 vibrators. TOAST presents an artificial gravity vector by a localised...

In a TNO and FOI joint study, nine fighter pilots participated in a threat detection and intercept experiment in the Swedish Dynamic Flight Simulator. Visual threat cueing with a simulated Gripen aircraft head-up display (HUD) symbology was compared with combined visual and vibrotactile threat cueing by means of the HUD symbology and a TNO...

Orienting oneself in space is not an easy task. On Earth, we combine visual, vestibular and pressure cues into a coherent concept of up and down. Since there are no cues from gravity in space, astronauts have to adjust the way they determine up from down, with the possible risk of space motion sickness. In three tasks performed by one astronaut...

This paper shows that tactile stimulation can override vestibular information regarding spinning sensations and eye movements. However, we conclude that the current data do not support the hypothesis that tactile stimulation controls eye movements directly. To this end, twenty-four subjects were passively disoriented by an abrupt stop after an...

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...

The application of dynamic vibrotactile displays in user interfaces is still a rare situation. There are, however, several important advantages of using the sense of touch as an information channel, especially in relation to overloaded or unavailable visual and auditory channels. We propose here to make good use of the qualities of the sense of...

In this paper we provide a brief introduction to MIAMM - a multimodal system for exploration of music databases. Among the modalities supported, haptics plays a central role. In particula1; multi-finger haptic interaction techniques for data shaping and exploration win be investigated. We explain our chosen methodology for designing these...

This paper describes two aspects of the application of tactile information presentation in the cockpit. The first half of the paper discusses why the tactile channel might be used instead of, or in addition to, the more common visual and auditory channels. It lists several categories of information used in cockpits and explores their...

As a three-dimensional object is moving through our world, we generally obtain a vivid impression of both its structure and its motion through space. The time-course of two-dimensional projections of the scene (optic flow) is important in conveying this three-dimensional information to us. The extent to which we can solve this specific inverse...

We quantified the ability of human subjects to discriminate the relative distance of two points from a slanted plane when viewing the projected velocities of this scene (orthographic projection). The relative distance from a plane (called relief) is a 3-D property that is invariant under linear (affine) transformations. As such, relief can in...
