Our aim was to examine the thigh, as a potential locus for directional orienting, within the vertical plane when the operator is seated (Figure 1). Specifically: (a) Examine the ability to locate a vibrotactile stimulation embracing the thigh. (b) Determine which region along the thigh provided more accurate localization. (c) Compare different burst… (More)
BACKGROUND Alerts in the cockpit must be robust, difficult to ignore, and easily recognized. Tactile alerts can provide means to direct the pilot's attention in the already visual-auditory overloaded cockpit environment. OBJECTIVE This research examined the thigh as a placement for vibrotactile display in the cockpit. The authors (a) report initial… (More)
<b>Motivation</b> -- Our goal was to design a thermal tactile display based on the <i>thermal grill illusion</i> sensation (created with spatially adjacent warm and cold stimuli), and to explore perception of information with such display. <b>Research approach</b> -- A prototype of a Thermoelectric Tactile Display (TTD) was developed, based on… (More)
Cognitive control has been extensively studied using the auditory and visual modalities. In the current study, a tactile version of the Simon task was created in order to test control mechanisms in a modality that was less studied, to provide comparative and new information. A significant Simon effect--reaction time gap between congruent (i.e., stimulus and… (More)
The Simon effect, one of the well-known stimulus-response compatibility effects, is usually explained as an expression of a conflict that occurs at the response selection stage. Here, we extended previous findings to provide evidence for post-response selection expression of the Simon effect. Following a presentation of a visual stimulus, participants… (More)
We report a vibrotactile version of the attention network test (ANT)-the tactile ANT (T-ANT). It has been questioned whether attentional components are modality specific or not. The T-ANT explores alertness, orienting, cognitive control, and their relationships, similar to its visual counterpart, in the tactile modality. The unique features of the T-ANT are… (More)
