Abstract

A portable computing device or “information appliance” having terse user input (e.g., limit set of keys) is provided with an improved user interface. A six-key embodiment is described that provides a “super-key” light entry and editing input system for ultra-portable devices, thus making it well suited for use with credit card-sized devices. In a preferred six-button embodiment, a credit card-sized device is modified to include an additional input button, an EDIT key. In user operation, pressing the EDIT key brings up a context sensitive pop-up menu, thus invoking the super-key feature. Customized user input controls, such as a Text Input Control (e.g., letter and number strips), are provided at appropriate times, for facilitating input. Underlying the super-key input is a heuristic sub-system that remembers and anticipates user input. In this fashion, the system can present in-context options for each application running on the target device, and present appropriate options during different phases of the execution of a variety of tasks. By remembering what the user has previously inputted and by using context-sensitive menus and adaptive “quick” lists, the system can anticipate what the user needs to do at any given time and can guide the user through a step-by-step process to complete each task, thus facilitating the tasks that users most often perform. By including adaptive techniques or built-in intelligence that allows the device to be faster and easier to use with each user session, the target device may anticipate the tasks users need to perform in specific situations and thus make those tasks increasingly easier.

Claims

1. A portable computing device having a processor, a memory device, a display and a terse set of physical input keys, the device comprising:

a plurality of applications, including a calendar function, an address book function, a to do function, a clock function and a preferences function;

a forward key for navigating in a forward direction among the plurality of applications and for navigating in a forward direction within each of said applications;

a backward key for navigating in a backward direction among the plurality of applications and for navigating in a backward direction within each of said applications;

a select key for selecting one of said applications for execution and for selecting items within a selected application, wherein selecting particular items within an application causes the interface to drill down into a lower level of the selected application; and

at least one key for providing a home function, an up-one-level function, and an off function, wherein the home function terminates execution of any application that is currently executing and returns the interface to a top level, the up-one-level function causes the interface to move one level toward the top level, and the off function shuts off the power of the computing device,

wherein, during execution of the address book function, the device displays a plurality of address book entries and a plurality of tabs, including category tabs and subcategory tabs, the category tabs and subcategory tabs comprising;

a plurality of category tabs that, combined, display every letter of an alphabet, with each tab displaying more than one letter of the alphabet, where each tab represents all address book entries that begin with any of the letters displayed on the tab, and wherein a user may use the select key to select into one of the category tabs;

a first plurality of subcategory tabs that, combined, display every letter of the alphabet, with each tab displaying exactly one letter of the alphabet, where each tab represents all address book entries that begin with the letter displayed on the tab, and wherein a user may use the select key to select into one of the first plurality of subcategory tabs; and

a second plurality of subcategory tabs, with each tab displaying exactly two letters of the alphabet, where each tab represents all address book entries for which the first two letters of the entry fall alphabetically between the two letters on the particular tab and the two letters on the next consecutive tab.

2. The device of claim 1, wherein one of the plurality of category tabs further displays a symbol other than a letter and that category tab further represents all address book entries that begin with any character other than a letter, and wherein the first plurality of subcategory tabs further comprises a subcategory tab displaying the symbol other than a letter and that subcategory tab represents all address book entries that begin with any character other than a letter.

3. The device of claim 2, wherein each of the plurality of category tabs displays exactly three symbols, beginning with the symbol that is not a letter and the letters ‘

a’ and

‘

b’

, and continuing in alphabetical order to the end of the alphabet.

4. The device of claim 3, wherein the calendar function provides a daily view, a weekly view and a monthly view.

5. The device of claim 4, wherein the address book function provides a tabbed list control combining a horizontal item list control rendered as tabs with a vertical list control.

6. The device of claim 5, wherein the preferences function allows a user to set a plurality of settings, including a time display format, a date display format, a password and a shut-off time period.

7. The device of claim 6, wherein, within the calendar function, the user may use the forward and backward keys to navigate among a plurality of calendar entries, the user may use the select key to select a particular calendar entry, and, upon user selection of a particular calendar entry, the device displays a subject, a date, a begin time, an end time, a location and a note related to the selected calendar entry.

8. The device of claim 7, wherein, within the address book function, a control is provided to allow a user to activate a menu for selecting a field by which the contacts will be sorted, the menu including a name field and a company field.

9. The device of claim 8, wherein, at the top level of the interface, the device displays a different icon for each of the plurality of applications, along with the current date and the current time, with the current date being displayed within the icon for the calendar function and the current time being displayed within the icon for the clock function.

10. The device of claim 9, wherein the terse set of physical input keys comprises five keys positioned along the right side of the display.

11. The device of claim 10, wherein the device is a credit card-sized device.

12. The device of claim 11, wherein the device further comprises a PC card port for connecting to a computer for data transfer between the device and the computer.

13. The device of claim 12, wherein, within the calendar function, a bell symbol is displayed next to a calendar entry to indicate that an alarm has been set for that calendar entry.
