Patent number: 6668177Abstract: An apparatus and method for displaying a plurality of icons on the display of a mobile terminal are provided. One or more characteristics associated with each icon are compared to one or more context values, such as time of day, geographic area, or user profile characteristics. Icons that best match one or more context values are represented in a display format that is enlarged in relation to other icons on the display device. The context values may include dynamically changing information, such as a current location of the user, so that as the user moves to a different geographic area, different icons are enlarged on the display device. The icons can correspond to application programs; logos (such as a corporate logo); documents; Web sites; or other objects. The icons can be grouped into a context bar that is displayed along an edge of the display device, and can be arranged in a horizontal, vertical, or mixed fashion. A magnifying glass metaphor can be moved over icons to highlight and select an icon.Type: GrantFiled: April 26, 2001Date of Patent: December 23, 2003Assignee: Nokia CorporationInventors: Marja Salmimaa, Tero Hakala, Juha Lehikoinen
