Mathias, Anne, Curry, David G., Donnelly, Conor and Drendel, Luke (2010): Slip Sliding Away II -- Slip Resistance of Dress Socks on Indoor Flooring. In: Proceedings of the Human Factors and Ergonomics Society 54th Annual Meeting 2010. pp. 1382-1386.

Laboratory testing was conducted to assess the slip resistance of men's dress socks on typical household flooring surfaces under wet and dry conditions. This study was conducted as a follow-up to a previous work on the slip resistance of athletic socks. Both of these studies attempt to fill the void of published data regarding the coefficient of friction between an indoor walking surface and the foot of a pedestrian wearing socks (rather than shoes). Eight different dress socks as well as a Neolite "shoe" were tested on wood and textured vinyl floors under both wet and dry conditions. The results in this study indicated that in terms of slip resistance, it makes little practical difference to a walker wearing loose-weave, non-nylon dress socks whether the flooring is wet or dry. Socks with tighter weaves, such as nylon socks, are significantly less slip-resistant on wet floors than under dry conditions.

Curry, David G. and Mathias, Anne (2009): Slip Sliding Away -- Slip Resistance of Athletic Socks on Indoor Flooring. In: Proceedings of the Human Factors and Ergonomics Society 53rd Annual Meeting 2009. pp. 568-571.

A laboratory study was conducted to assess the slip resistance of athletic socks on various household flooring materials under both wet and dry conditions. While prior studies regarding slip resistance have focused on shod walkers, there is a lack of published data on the coefficient of friction between stocking-clad feet and indoor flooring. To investigate this, four types of athletic socks were tested on samples of eight flooring materials for both wet and dry conditions. These results were compared to tests of a Neolite slider pad on these floors. The results indicated that for socks on textured vinyl flooring, there was no significant difference in slip resistance between the wet and dry conditions, though there was a trend towards greater slip resistance under wet conditions. Generally, it appears that the likelihood of slipping on other types of wet indoor walking surfaces is lower when walking in socks rather than shoes.

Kleiss, James A., Curry, David G. and Hubbard, David C. (1988): Effect of Three-Dimensional Object Type and Density in Simulated Low-Level Flight. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1299-1303.

Three-dimensional objects placed on simulated terrain surfaces are particularly effective as cues for altitude in simulated low-level flight. To conserve the limited edge processing capacity of computer image generators (CIGs), objects have typically been simple in shape and therefore fairly abstract in appearance. The present investigation sought to determine whether the apparent size of more detailed and familiar appearing objects (e.g., trees and bushes) serves as an additional cue for altitude in simulated low-level flight. Results showed no differences in performance between abstract objects and familiar objects. However, performance did improve with increases in object density, at least for some performance measures. These results suggest that CIG processing capacity may be most effectively utilized by increasing object density rather than individual object detail.
