In general, moving sensory stimuli (visual and auditory) can induce illusory sensations of self-motion (i.e. vection) in the direction opposite of the sensory stimulation. The aim of the current study was to examine whether tactile stimulation encircling the waist could induce circular vection (around the body's yaw axis) and to examine whether...

Non-parametric Wilcoxon Matched Pairs tests show that the percentage correct target ID in the Telepresence condition is significantly higher (87.5%) than in both Mono-Joystick (61.5%; p < .05) and Mono-Headtracking (64.6%; p < .005); Mono-Headtracking and MJ do not differ (p = .51). The repeated measures ANOVA on time to target identification...

We present the design and evaluation of a new demonstrator rifle sight viewing system containing direct view, red aim point and fusion of an (uncooled, LWIR) thermal sensor with a digital image intensifier. Our goal is to create a system that performs well under a wide variety of (weather) conditions during daytime and nighttime and combines the...

Het doorknippen van allerhande materialen met handtangen in de recycling industrie, levert een grote fysieke belasting. Het doel van dit project is het ontwerpen van een nieuwe hydraulische schaar voor het knippen van diverse materialen op moeilijk bereikbare plaatsen in een continuproces (zonder gereedschap te wisselen). Het project is gestart...

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...

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...

There is an increasing use of unmanned systems in military operations. Effective use of unmanned ground vehicles (UGVs) for counter IED and reconnaissance tasks under battlefield conditions has been reported. For operations in urban environment, good real time situational awareness for the operator is required to be able to manoeuvre and observe...

Future Unmanned Aerial Vehicles (UAV) will collaborate more directly with military manned aircraft. TNO Defence, Security and Safety investigated how to present UAV sensor images in a fighter aircraft cockpit in order to maximize target identification and flying performance. Ten military pilots performed several Close Air Support missions in a...

In this paper we explore the possibilities of tactile displays in sports applications, and report an experiment that shows that a tactile feedback systems improves rowing efficiency compared to traditional feedback systems. Earlier papers have shown that localized vibrations provide intuitive cues for orientation and navigation, i.e. where to...

The importance of uninhabited vehicles in military environments has been recognised for many years. Much progress has been made in fields such as robotics and data communications, but not so much on the human factors issues. This is partly due to the trend to strive for ever higher levels of system autonomy, leaving the operator the task of...

Vibrotactile displays use the skin as information channel. The last decade, there has been a growing interest in these displays because of their potential to decrease the threat of visual and auditory overload for people who work in challenging environments, such as astronauts, divers and fighter pilots. An additional advantage is that a...

Presenting waypoint navigation on a visual display is not suited for all situations. The present experiments investigate if it is feasible to present the navigation information on a tactile display. Important design issue of the display is how direction and distance information must be coded. Important usability issues are the resolution of the...

Tele-operated unmanned aerial vehicles (UAVs) have no operators on board and therefore enable extension of the present sensing and communication capabilities in civil and military missions, without unnecessarily endangering personnel or deploying expensive material. One should also realize that tele-operation from a control centre may result in...

In this paper we describe two case studies in which we tested a tactile torso display in a waypoint navigation task. The display consisted of eight vibrating elements in a belt around the operator. The case studies were both conducted in a vibrating working environment: a Gazelle helicopter and a high speed rigid inflatable boat. Both...

We investigated how to use vibrotactile stimuli to initiate limb movements, in particular wrist rotations. We compared stimulation of the to be activated muscle with specification of the direction to which that particular part of the body had to be moved (i.e., the use of an intrinsic or an extrinsic reference frame for motor control). Fifteen...

This paper presents a framework for mental workload that describes the adaptive nature of human beings in interacting with the environment. The framework is a result of many years of mental workload research in different complex task situations. This framework can be used to understand the role of mental workload in complex task situations as...
