Abstract

A handheld computer includes a processor; a memory in communication with the processor; and at least one light-emitting device that emits visible light as a visual indicator of an occurrence of a designated event. The processor is programmed to selectively activate the visual indicator in response to an occurrence of a designated event to provide the visual indicator to a user of the handheld computer. The processor is programmed to monitor for occurrence of two or more different types of designated events. The processor varies the visual indicator based on the type of the event for which occurrence is being signaled by that visual indicator, such that a different visual indicator is associated with each type of event for which the processor is programmed to monitor.

Claims

1. A handheld computer comprising:

a processor;

a memory in communication with said processor;

a display device in communication with said processor; and

at least one light-emitting device, separate from said display device, that emits visible light as a visual indicator of an occurrence of a designated event;

wherein said processor is programmed to selectively activate said visual indicator in response to an occurrence of a designated event to provide said visual indicator to a user of said handheld computer;

wherein said processor is programmed to monitor for occurrence of two or more different types of designated events wherein at least one of said types of designated events is taken from the following group;

an appointment recorded in a scheduling application of said handheld computer, receipt of an email, a battery powering said handheld computer has been depleted to a threshold level, an event in a game played using said handheld computer, and an input error on said handheld computer;

wherein said processor varies said visual indicator based on the type of the event for which occurrence is being signaled by that visual indicator, such that a different visual indicator is associated with each type of event for which said processor is programmed to monitor.

2. The handheld computer of claim 1, wherein:

said visual indicator comprises a blinking light; and

a rate of blinking of said visual indicator varies depending on which type of event is being indicated.

3. The handheld computer of claim 1, wherein said light-emitting device selectively produces light of different colors, each color corresponding to a different type of event the occurrence of which said visual indicator signals.

4. The handheld computer of claim 1, wherein:

said visual indicator comprises a blinking light; and

a different number of blinks corresponds to each different type of event the occurrence of which said visual indicator signals.

5. The handheld computer of claim 1, wherein:

said visual indicator comprises a blinking light; and

a different pattern of blinks corresponds to each different type of event the occurrence of which said visual indicator signals.

6. The handheld computer of claim 5, wherein a pattern of blinks comprises a combination of relatively short and long blinks.

7. The handheld computer of claim 1, wherein one type of event for which said processor is programmed to monitor is an appointment recorded in a scheduling application of said handheld computer.

8. The handheld computer of claim 1, wherein one type of event for which said processor is programmed to monitor is receipt of an email.

9. The handheld computer of claim 1, wherein one type of event for which said processor is programmed to monitor is that a battery powering said handheld computer has been depleted to a threshold level.

10. The handheld computer of claim 1, wherein one type of event for which said processor is programmed to monitor is part of a game played using said handheld computer.

11. The handheld computer of claim 1, wherein one type of event for which said processor is programmed to monitor is an input error.

12. The handheld computer of claim 1, further comprising a user input device, wherein said memory stores user input that specifies for what types of events the processor will monitor and produce said visual indicator.

13. The handheld computer of claim 1, further comprising a user input device, wherein said memory stores user input that dictates what different type of visual indicator will be generated with said light-emitting device in response to an occurrence of a particular type of event for which said processor monitors.

14. The handheld computer of claim 1, wherein said light-emitting device is a light-emitting diode.

15. The handheld computer of claim 1, further comprising an audible indicator, said processor issuing both an audible alert and a visual indicator in response to occurrence of a said event.

16. A method of providing a visual indicator with a handheld computer, said visual indicator comprising at least one light-emitting device that is separate from a display device for written data of said handheld computer, said method comprising:

selectively activating, by a processor of said handheld computer, said at least one light-emitting device on said handheld computer that emits visible light as a visual indication to a user of said handheld computer of an occurrence of a designated event;

wherein said handheld computer is programmed to monitor for the occurrence of two or more different types of designated events,

said method further comprises varying said visual indicator based on the type of the event for which occurrence is being signaled by that visual indicator, such that a different visual indicator is associated with each type of event for which said handheld computer is programmed to monitor, wherein said light-emitting device selectively produces light of different colors, each color corresponding to a different type of event the occurrence of which said visual indicator signals.

17. The method of claim 16, wherein:

said visual indicator comprises a blinking light; and

said method further comprises varying a rate of blinking of said visual indicator depending on which type of event is being indicated.

18. The method of claim 16, wherein said light-emitting device selectively produces light of different colors, and said method further comprises using a different color corresponding to each different type of event the occurrence of which said visual indicator signals.

19. The method of claim 16, wherein:

said visual indicator comprises a blinking light; and

said method further comprises emitting a different number of blinks depending on the type of event the occurrence of which said visual indicator signals.

20. The method of claim 16, wherein:

said visual indicator comprises a blinking light; and

said method further comprises emitting a different pattern of blinks depending on which of the different types of event the occurrence of which said visual indicator is signaling.
