In this study, we explore the conditions for accurate localization of vibrotactile stimuli presented to the abdomen. Tactile orientation systems intended to provide mobility information for people who are blind depend on accurate identification of location of stimuli on the skin, as do systems designed to indicate target positions in space or the status of(More)
This paper summarizes the design and application of a discrete event simulation model and animation of an intermodal transportation facility. We discuss the study objectives, the software selection criteria, the model architecture, the model results and conclusions drawn from the simulation study. Distinguishing features of the model architecture and(More)
This paper summarizes the design and application of a genend diserete-event simulation model of a rapid transit system. The model incorporates features of both 3-aspect, manual control and automatic train control. We discuss the model architecture and validation, and its application. The model has been applied to several systems, including one in Atlanta(More)
Spatial tactile displays allow for the cueing of directional information without drawing upon the visual and auditory channels. This work highlights the effectiveness of a tactual display versus a spatial auditory display baseline for augmenting a visual search task. Touch provides highly salient and covert signals that narrow the visual search space,(More)
