“…In addition, Rdey, Cochran, and Ballard (1982) manipulated an investigation of preferred shapes for warning labels and showed that the equilateral triangle pointing upward, diamond, octagon, and hexagon had higher preference scores than those for the other shapes tested. However, more recently, Andersson and Alm (2003) argued that shape is not good enough to distinguish among target categories. A sphere and one other symbol shape can be distinguished well, but when more shapes are used, the risk of confusion tends to be overwhelming.…”

This study investigated the effects of color combinations for the figure/icon background, icon shape, and line width of the icon border on visual search performance on a liquid crystal display screen. In a circular stimulus array, subjects had to search for a target item which had a diameter of 20 cm and included one target and 19 distractors. Analysis showed that the icon shape significantly affected search performance. The correct response time was significantly shorter for circular icons than for triangular icons, for icon borders with a line width of 3 pixels than for 1 or 2 pixels, and for 2 pixels than for 1 pixel. The color combination also significantly affected the visual search performance: white/yellow, white/blue, black-red, and black/ yellow color combinations for the figure/icon background had shorter correct response times compared to yellow/blue, red/green, yellow/green, and blue/red. However, no effects were found for the line width of the icon border or the icon shape on the error rate. Results have implications for graphics-based design of interfaces, such as for mobile phones, Web sites, and PDAs, as well as complex industrial processes.

“…At the Swedish Defence Research Agency (FOI) studies have been conducted (Andersson & Alm, 2002, 2003, Lif, Kylesten, Lindahl & Hedström, 2005 which support that 2D is good for tasks involving metric judgments (often focused attention) and 3D is good to gain overall situation awareness, SA (intergrated). SA is generated over time and is an important part of dynamic decisionmaking.…”

Decision makers in complex environments have a difficult task and researchers all over the world try to develop different decision aids to support them. This paper presents a study where a research platform with a combined 2D-and 3D-tool was used as a decision aid during two Military Operation in Urban Terrain exercises. Blue Force Tracking was used on some vehicles and soldiers to monitor their movements. The purpose of the study was to investigate if 3D visualization and distributed information in a C2 system, including Blue Force Tracking (BFT), gives the commander better SA. The results show that the commanders found the decision aid and the BFT very useful. The system enabled good SA and a shared awareness of what was going on in the battlefield. 2D was used 80% of the time and 3D was used for specific tasks where detailed information was needed to improve SA.

This report presents two experiments in the area of perspective aircraft displays. The focus was to understand symbolic and symbol relations in the 3D environment. In the first experiment, subjects' ability to distinguish five different aircraft symbol shapes was investigated together with the perception of their heading in the 3D space. The perspective used in this experiment was egocentric. The second experiment investigated the judgment of the spatial relation between an own-ship symbol and a target symbol. Thus, in this case the perspective was exocentric and two aspect angles were used for the camera position. Both experiments were carried out in non-dynamic scenarios. The display character was topographic with a superposed grid on the ground surface. The overall conclusion from the experiments is that judgments of azimuth and elevation are very difficult in these static scenarios. Also, symbol recognition of 3D pictorial symbols is problematic for complicated symbol shapes, depending on different appearances for various symbol headings in the 3D space.
