“…The results for horizontal displacement for the first three levels of scene complexity compare favorably to the results of our previous study (Barfield, et al, 1989). In both studies, as scene complexity increased, estimates of horizontal displacement improved.…”

To study the effect of five levels of scene complexity on performance of a final approach task, ten different animations representing combinations of scene complexity and distance intervals to threshold were modeled.For the experiment task, seven subjects were required to estimate the perceived point of impact as an extrapolation of the final approach path.The results indicated that there was a significant interaction between scene complexity and distance to the actual impact point for both horizontal and vertical components of the judgement task.In addition, increasing the level of terrain complexity lead to better performance in judgements o f horizontal displacement, however, the results for vertical displacements were unclear. The relationship between errors and performance for the experiment tasks are discussed.

“…Hills and mountains have been included in some investigations of flight simulator visual scene content (e.g., Barfield, Rosenberg & Kraft, 1989;Buckland, Edwards & Stevens, 1981;DeMaio, et al, 1983). Hills in MDS investigations, however, differed from studies cited above in that they did not extend above the horizon and, therefore, posed no serious obstacles to vision or navigation.…”

Multidimensional scaling (MDS) analyses of flight simulator visual scenes reveal that both the shape of the terrain surface as well as the spatial distribution of objects on the terrain are salient to pilots flying at low altitudes. MDS is based upon similarity ratings and it was deemed important to verify the relevance of these scene properties using a performance based task in a flight simulator. The task was an ascentldescent discrimination task similar to that used in other flight simulation research. Terrain shape and elements on the terrain (texture and objects) were factorially manipulated. Presence of hills as well as the spatial organization of objects on the terrain affected performance in some conditions. A positive effect of hills is noteworthy because hills did not extend above the horizon and therefore posed no vertical obstructions. Thus, they provide relevant information for perceiving altitude change apart from the role they may play in obstructing vision or navigation.

“…Several studies support this ambition. It has been shown in a flight simulator study that increasing the realism of ground terrain results in more accurate judgments in altitude as well as improved aiming [3]. Similarly, the altitude perception in pilots improved with higher object density in the visual environment [4].…”

Flight simulators are often assessed in terms of how well they imitate the physical reality that they endeavor to recreate. Given that vehicle simulators are primarily used for training purposes, it is equally important to consider the implications of visualization in terms of its influence on the userrsquo;s control performance. In this paper, we report that a complex and realistic visual world environment can result in larger performance errors compared to a simplified, yet equivalent, visualization of the same control task. This is accompanied by an increase in subjective workload. A detailed analysis of control performance indicates that this is because the error perception is more variable in a real world environment
