Unformatted text preview: r. This being said, an argument could be made for the importance of each sensory modality in the design of a potential GPS device. It is crucial to take as many environmental and personal factors into account as possible. In addition, even if a modality isn’t associated with a large quantity of advantages, the quality or significance of the benefits might outweigh the specific number of these assets (Gustafson- Pearce, Billet, Cecelja, 2007). Using visual devices offers a wide range of positive attributes to GPS systems. Foveal vision offers more benefits, but peripheral vision can be applied to direct the user’s attention, unlike foveal vision. When the information presented is spatial or a scene needs to be memorized rather quickly, foveal visions allows the user to be able to sense, perceive, and interpret the information appropriately, and use it with a GPS device to arrive at their target location. Foveal vision is also vital in the localization of 3D objects. Lastly, when the information that is introduced changes over time, illustrates “a real world physical object” (Van Erp et al., 2006), and/or is persistent, a navigation system utilizing the visual modality would be the most beneficial to the user (Van Erp et al., 2006). Although visually presented information has many favorable aspects, it also has a number of negative elements. The short- term memory store decays faster for iconic (visual) memory than echoic (auditory) memory. So, when information needs a rapid reaction time, visually presented data would be less reliable. In addition, visual navigation systems aren...
