Navigation Aids Advantages And Disadvantages

823 Words4 Pages

Humans get involved in navigation tasks daily. They have to make wayfinding decisions while walking in familiar and unfamiliar environments. Navigation is a combination of locomotion and wayfinding; it is planning and execution of a series of decisions which will lead the subject to her final destination (Montello, 2005). For this purpose supporting aids are used to facilitate people’s navigation and help them to make the right wayfinding decisions. Nowadays pedestrians use electronic devices that support a number of different navigation aids. For instance, people may navigate with the help of a digital map or with voice instruc-tions. There are also tactile applications which scan the immediate environment and let you know by vibrations if you made a right wayfinding decision or not (Pielot, Heuten and Boll, 2012). Therefore, the last decade researchers investigate the impact on user experience and navigation performance that comes from all these different navigation aids. They try to find out which navigation aid makes human’s navigation in familiar and unfamiliar environments more efficient and effective. They compare the different navigation supports individually as well as in combination (Rehrl, Häusler, Leitinger and Bell, 2014; Pielot et al., 2012; Kray, Laakso, Elting and Coors, 2003; Steck & Mallot, 2000). Nowadays 2D mobile digital maps are the most classic assistant aids that are extensively used by humans. However, they have been criticized due to their

    David Carr’s essay reflects very well on the title of his essay, “Keep Your Thumbs Still When I am talking to you”. Carr gives examples that relate to personal examples of how people today are constantly on their phones. By people always being on their phones it has become an act or rudeness towards other people from whom you were speaking to. Instead of keeping your elbows off of the table we will now be told to keep our thumbs still. In addition, similar to my experience at Professor Ataman’s lecture, David Carr discusses his experience at the South by Southwest Interactive Conference, at the conference he found that all the people had some sort of device with a screen that their eyes were attached too.

    Social location is important in knowledge production. One’s perspective is influenced by the location of his or her identity. Maps are useful for one to find one’s way and for navigation, but also to show others how to get somewhere. When one maps one’s experiences, an extra dimension is added to an ‘objectively’ created map. It becomes three dimensional, rather than flat.
