Abstract

A portable handheld computing device has a notification system that alerts a user of an event regardless of whether the device is on or off. The notification system has a notification mechanism that is activated upon occurrence of the event and remains active until the user acknowledges the activated mechanism. In one implementation, the notification mechanism is a light emitting diode (LED) mounted externally on the handheld computing device. The LED is visible to the user when the lid is closed onto the base (i.e., the device is off) or when the lid is open (i.e., the device is on). The notification mechanism also has a deactivation button mounted externally of the handheld computing device. The user depresses the deactivation button to deactivate the LED. The LED and deactivation button may be integrated as a single component.

Claims

1. A notification system for a handheld computing device having a display, the handheld computing device being capable of executing one or more applications, comprising:

a notification program callable by an application to schedule user notification events;

a light emitting diode (LED) that is separate from the display, the LED being mounted externally of the handheld computing device to visually alert a user when the event occurs;

the LED being coupled to receive power from a power supply of the handheld computing device so that the LED can remain activated even when the handheld computing device is off; and

a deactivation button mounted externally of the handheld computing device to deactivate the LED.

3. A notification system as recited in claim 1, wherein the notification program, in response to actuation of the deactivation button, sets a taskbar annunciator on the display of the handheld computing device that is associated with the application.

4. A notification system as recited in claim 1, wherein the notification program comprises:

a notification manager to manage one or more events, the notification manager generating a command to set a time when the event is scheduled;

an alarm manager to receive the set time command from the notification manager and to generate a set alarm command which informs a clock to set an alarm at the time of the event; and

an interrupt manager to receive an interrupt from the clock when the time of the event arrives and pass the interrupt to the notification manager so that the notification manager can activate the LED.

2. A notification system for a handheld computing device capable of executing one or more applications, comprising:

a notification program callable by an application to schedule user notification events;

a light emitting diode (LED) mounted externally of the handheld computing device to visually alert a user when the event occurs, the LED being coupled to receive power from a power supply of the handheld computing device so that the LED can remain activated even when the handheld computing device is off; and

a deactivation button to deactivate the LED, the LED and the deactivation button being integrated as a single component and mounted externally of the handheld computing device.

5. In a portable handheld computing device, an application program interface embodied on a computer-readable medium for creating a user notification that activates at least one sensory perceptible notification mechanism, the application program interface defining parameters comprising a time parameter that specifies when the user notification should occur and a type parameter that references a structure containing information specifying how the sensory perceptible notification mechanism is to be activated.

6. An application program interface as recited in claim 5, further comprising a parameter that identifies an application resident on the handheld computing device that is responsible for the user notification.

7. An operating system for a portable handheld computing device, embodied on a computer-readable medium, comprising an application program interface as recited in claim 5.

8. A method for operating a handheld computing device comprising the steps of:

scheduling an event;

upon occurrence of the event, emitting a light that is visible externally of the computing device; and

continuing to emit the light even when the handheld computing device is off.

9. A method as recited in claim 8, further comprising the step of blinking the light.

10. A method as recited in claim 8, wherein the event pertains to an application running on the handheld computing device, the method further comprising the step of displaying an annunciator associated with the application.
