Abstract

A palmtop computer system that incorporates mechanical buttons that combine the task of turning the palmtop computer system on and starting a particular application program. Furthermore, the same mechanical button can be used to navigate the application program to find the information that is most likely needed by the user. Additionally, external devices can be coupled to the palmtop computer system in a manner that allows the external hardware device to initiate specific application programs that cooperate with the external hardware device.

Claims

1. A computer implemented method of preparing a computer system for use, said computer system including a screen display with a screen display area, said method comprising the steps of:

accepting a particular application button press by a user, wherein said computer system includes a plurality of application buttons for selecting applications, wherein said plurality of application buttons include said particular application button, wherein each application button of said plurality of application buttons;

is associated with a particular application program, and

is located at a location external to said screen display area; and

in response to said particular application button press;

waking a processor, and

executing the particular application program associated with said particular application button.

2. The method of claim 1, wherein

said processor and said screen display are incorporated within a housing;

and

each application button of said plurality of application buttons is integrated and fixedly attached to said housing.

3. The method of claim 2, wherein each application button of said plurality of application buttons is a mechanical button.

4. The method of claim 1, wherein the steps further include:

receiving data that indicates a user selected state for the particular application program; and

in response to said particular application button press, bringing the particular application program associated with the particular application button into said state.

5. The method of claim 1, wherein said step of waking a processor in response to said particular application button press includes interrupting said processor such that said processor enters an interrupt service routine.

6. The method of claim 5, wherein said interrupt service routine tests a register to determine which application button from said plurality of application buttons has been pressed.

7. The method of claim 1, wherein the steps further comprise executing a program that reconfigures a new particular application program to be associated with a particular application button of said plurality of application buttons.

8. The method of claim 1,

wherein the computer system is a mobile computer system;

and

wherein the steps include;

determining whether said particular application button was pressed for a period of time that exceeds a predetermined period of time, and

if said particular application button was depressed for a period of time that exceeds the predetermined period of time, then said particular application program transmitting a data record.

9. A computer apparatus, said computer apparatus comprising:

a screen display with a screen display area;

a processor, said processor having a low power consumption sleep mode, said processor having a hardware interrupt line that awakes said processor from said sleep mode;

a plurality of application buttons for selecting applications, wherein each application button of said plurality of application buttons;

is associated with a particular application program,

is located at a location external to said screen display area, and

asserts said hardware interrupt line when said each application button is pressed; and

interrupt service code for handling processor interrupts caused by said hardware interrupt line being asserted by pressing a particular application button of said plurality of application buttons, said interrupt service code causing execution of the particular application program associated with said particular application button.

10. The computer apparatus of claim 9, wherein

said processor and said screen display are incorporated within a housing;

and

each application button of said plurality of application buttons is integrated and fixedly attached to said housing.

11. The computer apparatus of claim 10, wherein each application button of said plurality of application buttons is a mechanical button.

12. The computer apparatus of claim 9, wherein

said computer apparatus is configured for receiving data that indicates a user selected state for said particular application program associated with said particular application button;

and

said interrupt service code causing said execution of the particular application program causes bringing said particular application program associated with said particular application button into said state.

13. The computer apparatus of claim 9, wherein said interrupt service code tests a register to determine which application button from said plurality of application buttons has been pressed.

14. The computer apparatus of claim 9, wherein said computer apparatus is configured for executing a program that associates another application program with said particular application button of said plurality of application buttons.

15. The computer apparatus of claim 9,

wherein the computer apparatus is a mobile computer system;

wherein the computer apparatus is configured for determining whether said particular application button was pressed for a period of time that exceeds a predetermined period of time; and

if said particular application button was pressed for a period of time that exceeds the predetermined period of time, then said interrupt service code causing said execution of the particular application program causes said particular application program to transmit a data record.
