Visual search

In the wide field of applications, a visibility level VL = 3 - 60 is recommended. For our recognition task, we are obliged to take into account that our random conditions are far from the experimental conditions of the basic researches (Young test person with a high visus under ideal environmental conditions) [4]. Furthermore in our case we have a more difficult visual searching task. Parameter variations as the increase of presentation time from 0,2 to 1.0 s. and the detection propability from 50% to 100% are taken into account [5] In spite of the gliding variations of the parameters as well as the visibility level, for simplification let us assume VL = 10 as minimum requirement.

In 10 children with rolandic epilepsy, carbamazepine impaired memory and possibly visual search tasks (122). Evaluation of individual data suggested that some children were especially vulnerable to the adverse effects of carbamazepine on cognition. The authors did not comment on the fact that rolandic epilepsy is regarded as a syndrome for which treatment in most cases is not indicated. 

We can naturally visualize search schemes where the measurements are spaced irregularly and the size of the final interval obtained would depend on the experimenter s luck. In such cases it is difficult to decide a priori which interval should be used to measure the effectiveness of the scheme. We shall take as our final interval the largest interval that we...

In a study conducted by the National Highway Traffic Safety Administration, a moderate dose of marijuana alone was shown to impair driving performance however, the effects of even a low dose of marijuana combined with alcohol were markedly greater than for either drug alone. Driving indices measured included reaction time, visual search frequency (driver checking of side streets), and the ability to perceive and/or respond to changes in the relative velocity of other vehicles. ... 

Note that search is a serial sequential process, terminating upon successful detection of a discrete indication (such as a surface scratch) caU a target in visual search. Because of its sequentieil nature, it is a resource-hmited rather than data-fimited process (Wickens 1991). As such, the probability of detection increases with time spent searching in a manner dependent upon the search plan.

The human inspection models of visual search and human decision making were shown to be particularly applicable leading to a task analytic framework using hierarchical task analysis (HTA). In this way, human factors knowledge could be applied systematically to observed FPI processes. Visits were made to several engine repair facilities owned by major air carriers and engine manufac-...
