In 2018, there were 3.6 billion mobile internet users worldwide, which shows that digital designers have to tackle navigational patterns and menu anchor interactors for smartphone-sized screens early in their projects. As user satisfaction is crucial for the success of a website, and as successful navigation through a menu system is imperative to user satisfaction, the menu system is a key component in the UI. This study concerned three types of menu anchor interactors in smartphone UIs (Transient, Top persistent, and Navigation hub), on three website types (Single service, Brand, and Service directory). The goal was to investigate what influence the website type has on the user’s preferences of menu anchor itneractors.

The theoretical base is previous research on menu systems in graphical UIs. The study was done by a questionnaire where the participants were presented images of three different menu anchor interactors on three different website types, and asked to score the assumed helpfulness of the menu anchor interactor from one to seven on a Likert scale. In addition, they were asked to clarify their scoring in a qualitative response.

The key findings are that users prefer menu anchor interactors that display several navigation links, and that there are indications that the Top persistent menu anchor interactor works best on the Service directory website type, while Single service and Brand website types seem to benefit from a Navigation hub. However, the results also show the importance of studying UI components in their full UI context, as the whole UI affects the perceived usability of the menu anchor interactor.
