Even though data visualization is a common analytical tool in numerous disciplines, it has rarely been used in agricultural sciences, particularly in agronomy. In this paper, we discuss a study on employing data visualization to analyze a multiplicative model. This model is often used by agronomists, for example in the so-called yield component analysis. The multiplicative model in agronomy is normally analyzed by statistical or related methods. In practice, unfortunately, usefulness of these methods is limited since they help to answer only a few questions, not allowing for a complex view of the phenomena studied. We believe that data visualization could be used for such complex analysis and presentation of the multiplicative model. To that end, we conducted an expert survey. It showed that visualization methods could indeed be useful for analysis and presentation of the multiplicative model.

“…image quality, image manipulation, stereoscopic experiences, natural manipulation, interaction and user interface could clearly be seen where expert evaluators uncover the problems. By dividing the problems into two categories, Display related problems and Interactivity problems Opyio and Horvath [27] were able to identify research directions in the area of 3D displays, including display hardware problems.…”

“…The criteria presence, perceptual expectations, natural interaction, compatibility and collaboration criteria closely matched the quality characteristics widely used in the evaluation of virtual reality applications by referring to Sutcliffe [27] and describes sets of requirements for a spatial product visualisation system, including fourteen visualisation requirements, nine computational, eight interaction requirements and seven other requirements. Prior to writing these two papers, Opyio and Horvath [26] published a conference paper, also on heuristics evaluation on holographic displays.…”

Although generic usability heuristics lists have been popular with researchers and practitioners, emerging new technologies have called for more specific heuristics. One of these heuristics was proposed by Sutcliffe and Gault in 2004 [37]. This paper examines research which has cited these heuristics with the aim to see how it has been exploited. The results showed that a fifth of the papers citing the heuristics have used the heuristics fully or partly, and that researchers have adapted it to their current needs. Following this result we proposed that a patchwork of heuristics might be more useful than a single list. We evaluated a crisis management training simulator using the virtual reality heuristics and discussed how the outcome of the evaluation fitted the patchwork.

Three-dimensional (3D) visualization technologies are increasingly applied in visualization of virtual product models. Devices such as 3D glasses, head/helmet mounted displays (HMDs), stereo projectors and in some instances even some of the emerging visualization technologies including, for instance, holographic displays, swept volume displays and other volumetric displays are examples of technologies that can be used in visualization of virtual models of engineering products. These technologies allow viewers (i.e. in this case designers and engineers) to explore various aspects of products such as appearance or shape more aptly. 3D virtual product models are especially useful for activities that require space imagination such as evaluation of concepts, aesthetics review, assembly verification and ergonomics review. The problem, however, is that interactivity of most of the existing 3D visualization technologies is very limited. Therefore, this paper describes an attempt aimed at developing intuitive interaction methods for visualization of 3D product models in truly 3D visualization environment and at investigating how basic tasks such as selecting, rotating or moving 3D virtual object in 3D scene can be accomplished. A holographic display is used as a case study truly 3D visualization technology. Different interaction methods have been developed and user tests carried out to qualitatively evaluate the usability and suitability of these methods. Motion tracking is seen as a practical way for manipulating 3D product models in 3D workspace while spatial touch screen with tangible object and virtual menu is seen as a practical method for manipulating menu items. The paper also illustrates how these two interface methods can be used for performing certain basic interactive product visualization operations in 3D workspace.
