Abstract

A system for displaying "help" information concerning the functioning of the controls of an electronic system. A "help" control is provided which, when operated, places the system in a "help" mode. When the system is in the "help" mode, system controls are disabled from performing their normal function and, in response to the operation of a control and were appropriate to an indication of the current state of the system, a selected "help" text is displayed. The system is adapted to operate for both analog and digital controls and to provide the "help" text in a window on the display so that normal operation of the system may continue while the "help" text is being displayed.

Claims

1. In a system which is operable in a plurality of different modes and which has a video display and a plurality of controls, each of which controls is operable to be in a plurality of different states, the state of the control influencing a selected system function;

a mechanism for displaying information concerning the system function of at least selected ones of said controls for the current state of the system comprising;

a help control;

means responsive to a first operation of said help control for placing said system in a help mode;

first means operative when the system is in the help mode for disabling the system from responding to the operation of said selected ones of the plurality of controls to influence the corresponding functions, the system operation otherwise continuing substantially unchanged when the system is in the help mode;

second means operative when the system is in the help mode and in response both to the operations of each of said selected ones of said plurality of controls when the system is in the help mode and to said current state of the system for displaying on said video display selected help information concerning the particular function controlled by the operation of each said selected ones of the plurality of controls; and

,

means for taking the system out of the help mode.

2. A mechanism as claimed in claim 1 wherein said means for taking the system out of the help mode is operative in response to a second operation of said help control.

3. A mechanism as claimed in claim 1 including means for causing the display of said selected information to appear in a window on said video display, the display of data of a type selected prior to entering a help mode continuing while the system is in help mode.

4. A mechanism as claimed in claim 1 wherein said plurality of controls include both analog and digital controls.

5. A mechanism as claimed in claim 1 including means operative when the system is placed in the help mode for displaying a selected help screen.

6. A mechanism as claimed in claim 1 wherein all of said plurality of controls are disabled when the system is in the help mode.

7. A mechanism as claimed in claim 1 wherein said system is an ultrasonic medical imaging system.

8. A mechanism as claimed in claim 1 wherein said selected information is an appropriate help text;

including memory means, means for storing in said memory means at least one help text for each of said controls, plural help texts being stored for controls which function differently for different states of the system; and

wherein said second means is operative to retrieve the appropriate help text for the operated control and current system state and to use such retrieved help text to control said video display.

9. In a system which is operable in a plurality of different modes and which has a video display and a plurality of controls, each of which controls is operable to be in a plurality of different states, the state of the control influencing a selected system function, a method for displaying information concerning the system function of any of at least selected ones of said controls for the current state of the system comprising the steps of:

placing said system in a help mode in response to a first operation of a help control;

disabling the system from responding to the operation of selected ones of the plurality of controls to influence the corresponding functions when the system is in the help mode, the system operation otherwise continuing substantially unchanged when the system is in the help mode;

displaying on said video display selected help information concerning the functions controlled by the operation of each of said selected ones of said plurality of controls when the system is in the help mode and in response to the operation each said selected ones of said plurality of controls and the current state of the system; and

,

taking the system out of the help mode in response to a selected user input.

10. A method as claimed in claim 9 wherein the step of taking the system out of the help mode is operative in response to a second operation of said help control.

11. A method as claimed in claim 9 including the step of causing the display of said selected information to appear in a window on said video display, the display of date of a type selected prior to entering a help mode continuing while the system is in help mode.

12. A method as claimed in claim 9 wherein said plurality of controls include both analog and digital controls.

13. A method as claimed in claim 9 including the step of displaying a selected welcome help screen when the system is placed in the help mode.

14. A method as claimed in claim 9 wherein said system is an ultrasonic medical imaging system.

15. In a system which is operable in a plurality of different modes and which has a plurality of controls and a video display, the video display being adapted to display a selected image, the controls each being operable to any one of a plurality of different states to influence a selected characteristic of the displayed image;

a mechanism for displaying information concerning the functioning of said controls for the current state of the system comprising;

a help control;

means responsive to a first operation of said help control for placing said system in a help mode;

first means operative when the system is in the help mode for disabling the system from responding to the operation of at least selected ones of said plurality of controls to influence the corresponding characteristic of the displayed image, the system operation otherwise continuing substantially unchanged when the system is in the help mode;

second means operative when the system is in the help mode and in response both to the operation of each of said selected ones of said plurality of controls when the system is in the help mode and to said current state of the system for displaying on said video display selected help information concerning the particular display characteristic controlled by the operation of each said selected ones of said plurality of controls; and

,

means for taking the system out of the help mode.
