Unformatted text preview: t as good at drawing and directing the user’s attention to the task at hand. This means that when information is not spatial or is SIGHT, HEARING, AND TOUCH IN NAVIGATION SYSTEMS 5 outside the primary area of interest (periphery), it is harder to sense and interpret the information (Van Erp et al., 2006). An example of an appropriate time to use a visual GPS is when someone needs 3D information about the environment, or when someone is trying to map out a road trip to find the shortest route. This person could use a visual GPS to learn about their surroundings during their travels, and see with their eyes which states or cities they are passing through or where they are in relation to these states and cities. These systems are beneficially because a navigation system using the senses of hearing or touch cannot provide this type of information to the user. Incorporating auditory components into GPSs also offers a wide variety of positive features and drawbacks. Using speech as the auditory element allows for a warning or alert to be communicated most effectively across the different modalities. In addition, using non- speech as the auditory element is ideal for optimizing reaction time. Like visual systems, GPS devices using the sense of hearing are also useful when the information presented needs to be memorized or the data “concerns absolute quantitative parameters” (Van Erp et al., 2006). While the short- term memory store for iconic memory decays after 200- 300 milliseconds, information in the echoic memory can be retained much lon...
