Unformatted text preview: ger for 2- 4 seconds. The main advantage of auditory signals in navigation instruments is that it is terrific at drawing a user’s attention. No other modality is as proficient in this task, making sound a vital overall contributor (Van Erp et al., 2006). The benefits from using auditory signals are extremely significant, however, the disadvantages also seem to have a large impact on the effectiveness of the GPS SIGHT, HEARING, AND TOUCH IN NAVIGATION SYSTEMS 6 device. Without rehearsal, the echoic memory store has a finite capacity and also greatly increases cognitive load (Davis, 2007). Echoic memory is also immensely sensitive to load and presentation conditions and easily susceptible to interference (Van Erp et al., 2006). Auditory GPS systems are very popular for drivers because of their limited visual capacities. Since drivers need to keep their eyes on the road ahead of them, they aren’t always able to look at a map or visual GPS. In these cases, their navigation device can read out or speak directional instructions to them. This type of route guide is pivotal because it can provide the same information, just in a different manner (because visual information cannot be utilized at this time). A relatively new field of study concerns using the sense of touch to reach a specific location. Haptic vibrating belts are a type of tactile GPS system that is currently being invented and tested in military settings (Boyle, 2011). Some advantages of these systems include being especially effective when information is private or time related (Graham- Rowe, 2011). They also spatial...
