Celltop from Aricent is an On-device portal that makes it easier for mobile users to discover content on their mobile phones. Each cell (Mobile Widget) is a small application that does one simple task (E.g. Display stock quotes, Breaking News etc). Mobile users can have any number of cells (Mobile Widgets) on their mobile phones – one for each type of content (sports, news, weather and entertainment). They can combine and arrange cells in their preferred order to get an entirely personal and enjoyable experience. A mobile phone typically comes loaded with default cells; however, users can easily download new cells from the network. Information on cells is always updated, even if the cells are inactive. Celltop stores a user’s location and preferences and keeps updating relevant cells constantly. A user can get updated information instantly. For example, if the user has not used the sport’s cell for a while, only a few clicks will present the latest score of his or her favorite sport.



Celltop[1534] creates an environment that is similar to that of desktop on a mobile phone. It provides simple navigation in the face of expansive content, bringing users immediate updates on the topics of their choice. Celltop screens provide a shortcut to users’ top content, from personal stocks to the SMS inbox, from local weather to the latest news updates. Unlike other content-centric interfaces, Celltop provides direct access both to external content and traditional handset functionality, an integration that marks a major evolution in handset applications.
<br />Celltop was developed by Aricent and frog Design,a strategic design consultancy firm of Aricent,and was first deployed by Alltell Wireless[1535] in January 2007.

Celltop is a significant progress towards usablity experience in the mobile world. It defies the limitations of small screens and fonts, unattractive and static display,cumbersome navigation, and long waiting time for downloading online content. The speed with which content is displayed to the user is also significantly faster than using a WAP portal.
