Four methods of presenting stores management information were evaluated in a flight simulation: 1) alphanumeric, 2) color pictorial, 3) black and white pictorial, and 4) alphanumeric/color pictorial. Results indicated that pilots performed equally well with the alphanumeric, color pictorial, and alphanumeric/color pictorial formats but that performance with the black and white pictorial format was significantly worse than all three of these formats. Subjective data indicated significant pilot preference for the alphanumeric/color pictorial format. These results indicate one potential advantage of color pictorial formats in the cockpit. Mainly, in addition to the specific information provided by the alphanumeric format, the color pictorial format provides a “situational awareness” where the pilot can obtain important information at a glance. Also supported by this study is the continued exploration of color computer graphics in the cockpit to increase the efficiency of information transfer between the pilot and the aircraft.

Stereo pairs of electron microscope images provide valuable visual impressions of the three-dimensional nature of specimens, including biological objects. Beyond this one seeks quantitatively accurate models and measurements of the three dimensional positions and sizes of structures in the specimen. In our laboratory, we have sought to combine high resolution video cameras with high performance computer graphics systems to improve both the ease of building 3D reconstructions and the accuracy of 3D measurements, by using multiple tilt images of the same specimen tilted over a wider range of angles than can be viewed stereoscopically. Ultimately we also wish to automate the reconstruction and measurement process, and have initiated work in that direction.Figure 1 is a stereo pair of 400 kV images from a 1 micrometer thick transverse section of frog skeletal muscle stained with the Golgi stain. This stain selectively increases the density of the transverse tubular network in these muscle cells, and it is this network that we reconstruct in this example.

EM specimens often contain 3-dimensional information that is lost during micrography on a single photographic film. Two images of one specimen at appropriate orientations give a stereo view, but complex structures composed of multiple objects of graded density that superimpose in each projection are often difficult to decipher in stereo. Several analytical methods for 3-D reconstruction from multiple images of a serially tilted specimen are available, but they are all time-consuming and computationally intense.
