“…It must be concluded that current small screen devices are --cognitively --challenging to use. This is true for young adults, but it is even more valid for children, which -due to their developmental status-can be categorized as "weaker" users [8,24,25,26]. The fact that both navigation aids advantaged users' performance in the menu shows that the disorientation problem in small screen device menus can be basically relieved.…”

Abstract. Disorientation in small-screen-device menus is a frequent problem for many users. This study examines if navigation aids containing spatial information may reduce disorientation. Two aids were implemented into a simulated mobile phone: One aid contained spatial cues, providing an overview of menu locations and routes, the other delivered landmark knowledge, representing salient features on the route. Also, a condition without any aid was examined. 24 children and 24 adults solved four phone tasks twice. Dependent variables were navigation effectiveness and efficiency. Performance was lowest when users were not supported by any aid. The aid providing survey knowledge yielded the best performance. Though, the relative benefit by aids revealed to be age-related. While the aid providing survey knowledge was advantageous for all users, the aid delivering landmark knowledge was especially harmful for the children, which showed considerably more detouring in the menu. It is concluded that navigation aids reduce disorientation in small devices, especially those which support users to build up a spatial representation of the menu.

“…Frequently, several buttons must be pressed in combination to achieve the desired functionality. A previous study showed that users take more time and make more errors when a single UI object provides multiple and/or dissimilar functions (Ziefle et al, 2006).…”

“…One of the principle concepts behind the development of our user-friendly software for our MIni Food E-Additive Database (MIFED). was the notion that the complexity of handling a mobile device is likely to reduce its ease of use and thus its perceived usefulness to the user (Ziefle et al, 2006;Ziefle & Bay, 2004). …”

Our project has developed an application for mobile telephones to provide a catalogue of Enumbers and E-names: the food additives widely known as "E-numbers". Our application, the MIni Food E-Additive Database (MIFED) provides a user interface that is friendly and easy to use. To achieve our main goal of platform independence we applied the JAVA programming language to implement our software. Thus, based on JAVA our software can run on a very wide range of mobile devices. The development process of the software is outlined in this paper.
