Augmented Navigation: A Cognitive Approach

Navigation, specifically web navigation and application navigation, is ubiquitous in user interfaces when interacting with personal computers and mobile devices. Applications and web sites typically rely on a set of controls (e.g., buttons, menus, hyperlinks) to aid the user in traversing the system or take the user to their intended target destination. In this paper, we propose a methodology based on cognitive modeling to augment navigation controls and provide users with diagnostic information about their destination, even before navigation takes place. By providing critical supplementary information, augmented navigation informs the user about the target and helps the user decide where to navigate. Thus, augmented navigation can be helpful in reducing the number of steps when completing a task. It can be especially useful in low-bandwidth environments or slow systems, where there is a significant penalty associated with erroneous or unnecessary navigation. In addition, this approach is suitable for complex systems that present the user with a large number of potential destinations and the user has to make a series of decisions to determine the appropriate navigation target. While any type of user interface (UI) control (e.g., buttons that perform actions) can be augmented with supplementary information, for the purposes of this paper we will focus on navigation controls.
Older adults’ use of mobile device: usability challenges while navigating various interfaces
Published in Behaviour & Information Technology, 2020
For example, panel position and menu structure were primarily studied in desktop context. As indicated by previous studies, a suitable menu position, such as left panel design (Torun and Altun 2014) and placement of well-designed intra-article navigation schemes (Cuddihy and Spyridakis 2012), could help in improving web navigation performance in terms of recall and retention. Besides, menu structure also matters. It was reported that a vertical menu that displays the full context of menu items at once are better than a dynamic menu that demands additional action to access more menu items each time, especially for users with decreased perception and cognitive capabilities (Puerta Melguizo, Vidya, and van Oostendorp 2012; Leuthold et al. 2011). Later, with the prevalence of feature phones, the usability problems of menu structure become more salient because system navigation was considerably hampered due to restricted screen size and expanded information. Older adults could not easily understand how menu items were spatially structured or how the functions, nodes, and information were arranged due to declining memory, spatial ability, and perceptual capability; thus these users easily experienced disorientation within deep menus and nested functions (Ziefle et al. 2007; Kim et al. 2007; Ziefle and Bay 2006; Downing, Moore, and Brown 2005). Simple, flat menu structures become the major recommendation for improving older adults’ navigation behaviour (Ziefle and Bay 2006). In addition, text labels for icons and buttons can also help older adults memorise functions, locations, and navigation paths (Chen, Chan, and Tsang 2013; Hassan and Md Nasir 2008; Kim et al. 2007; Ziefle and Bay 2005, 2006).
