| Popis: | This paper reports on research into techniques for information representation in complex dynamic environments. Such environments can be described in a two-dimenstional space as being one with high information densities, and with high rates of change. In particular, we are investigating how information layering, visual depth and transparency using the new Multi-Layered Display (MLD) technonlogy can be combined to improve information uptake in such environments. The results show that there is no advantage in using the MLD in simple reading and interaction tasks. However, user performance was observerd to be significantly better when using layering techniques on the MLD under increased task difficulty conditions that approximate information handling challenges in command and control activities. Introduction New technology affords new ways of doing things. The Multi-Layered Display is a new display technology that comprises two LCD screens separated by a perspex layer. Information presented on the rear LCD is visible through the perspex and front LCD screen (Figure 1). By manipulating transparency, colour, movement of the presented information, other object-centred visual depth cues such as perspective and shadow (Wickens & Hollands, 2000) together with the physical sepration of the LCD layers, we can create novel information representation design techniques such as layering for segregating information, and visual association using coordinated movements between layers. We hypothesise that such display techniques can help improve human performance in visual information search, association and comparison – important human information handling aspects in understanding complex situational information typically encountered in naturalistic decision making environments such as command and control. Understanding how such designs can work is the first step towards being able to harness the capabilities that the new technologies such as the MLD affords. A number of investigations into the use of the transparency have been reported in the literature. (Kooi, 2001) projected additional information on an glass placed at a 45 degree angle to a computer monitor to overlap information at different degrees of transparency. TrueDepth, a display technology company in New Zealand, developed that concept into the world’s first commercial prototype called the Multi-Layered Display, MLD (Deep Video Imaging Ltd, 2001). More recently other researchers have investigated the use of transparency in conventional single layered displays in relatively less dynamic image editing tasks (Baudisch & Gutwin, 2004), perception and interference effects of overlapping information using a modified Stroop test (Aboelsaadat & Balakrishnan, 2004), and a visual tracking task simulating the monitoring of a situation display in air battle management together with a digit-pair task presented in varying levels of transparency, to simulate concurrent operational demands (Bolia, Nelson, Middendorf, & Guilliams, 2004). |
