The small screens of handheld mobile devices represent a challenge in presenting a sufficient and useful amount of data on the user interface without requiring extended interaction from the user by scrolling the page or otherwise navigating to different locations for that data. Consequently, the design, presentation, and layout of information and user interface controls is a constant delicate balancing act between the display of an adequate quantity of data (and controls used to view and manipulate that data), and the amount of screen real estate used on the small display screen . In some instances, the user is the best judge of how data should be presented in the context of his/her task, and should therefore be provided with a technique to tailor its display. A new control must be developed to allow the user to maximize the data presentation and the real estate the data occupies on the screen. This disclosure describes such a control. Disclosed is an invention that integrates the ability to either scroll individual items individually in a list (thereby conserving screen real estate) or to expand the size of the list and then scroll, with a scroll bar, a group of multiple lines of data (using additional screen real estate) in a list via a single, expandable control. With this control, the user can use the context of the task to determine him/herself if the data is important enough, or more efficiently viewed, to require more screen real estate. Additionally, this invention also includes information within the control that informs the user of the quantity of items that are included in the collapsed data field. This provides the user with meaningful information regarding whether the control should be expanded to enhance the viewing of data. This invention minimizes the data on the screen but also provides the user with two scrolling options in a single control. This will advance the usability of mobile devices by allowing for an increase in the data that can be viewed and enhancing form navigation, while also speeding up scroll time.

Integrated Method for Scrolling Individual or Multiple Items in a Data Field on a Handheld Mobile Device

The preferred embodiment is described in an email scenario in a series of figures below.

In Figure 1., the user is viewing the list of addressees of an email he is currently writing. In each data field, he can scroll through email addresses individually by tapping the down arrow with the stylus (the down arrow is the only directional control available because the user is at the beginning of each list), or by tapping the "expand" (square) icon the user can expand the data field and use the scrollbar to scroll through multiple items. Note also, the numbers within the square icon, indicating the total of items within the data field. In the interest of space, if the quantity of items exceeds single digits, then an ellipsis ("...") may be displayed in place of an actual number.

Figure 1. The default collapsed position of the data field .

The user expands the data field by tapping the square numbered icon, as seen in Figure 2. The number (or ellipse, as necessary) in the square changes to a "minus" to indicate the collapse function. This view allows the user to scroll a larger list of data. To makes the tap travel distance easier for the user when he wants to collapse the data field, each end of the scroll control contains the collapse icon.
