Abstract

A method and system are provided for entering input into a computing system. The method involves detecting one or multiple input movements using a sensing panel associated with the computing system and classifying each detected input movement as being of a particular type. Each detected input movement is translated to an instruction signal by consulting a knowledge database. The instruction signals are transmitted to the computing system for execution. Translation of a detected input movement to an instruction signal involves a main process and one or more sub-processes, wherein each sub process is invoked by the main process in response to a particular type of detected input movement.

Claims

1. A method of entering input into a computing system, the method comprising the following steps:

detecting one or multiple input movements using a sensing panel associated with the computing system;

classifying each detected input movement as being of a particular type;

translating each input movement to an instruction signal by consulting a knowledge database; and

transmitting the instruction signal to the computing system;

wherein translation of a detected input movement to an instruction signal involves a main process and one or more sub-processes, the main process and the one or more sub processes together form a hierarchical control structure in which the main process determines whether an input movement corresponds to a prompt to invoke a particular mode, and where a particular mode is indicated, the main process invokes a sub process in that mode,

each sub process is assigned to translate one or more particular input movements into corresponding instruction signals by consulting the knowledge database,

the main process manages one or more sub processes by assigning a priority value such that a sub process having a minor priority value does not impede a sub process having a major priority value; and

the whole sensing panel functions as a single sensing area and the main process and one or more sub-processes can be invoked regardless of the location of the detected input movement on the sensing panel.

2. A method of entering input into a computing system according to claim 1, wherein each particular type of input movement is associated with operation of the sensing panel in any one of the following modes:

(a) keyboard modes;

(b) mouse modes;

(c) scripting modes;

(d) device modes;

(e) customer modes; and

(f) idle mode.

3. A method of entering input into a computing system according to claim 2, wherein each invoked sub process claims a region of the sensing panel such that any input movements received via the claimed region of the sensing panel will be translated by the sub process having claimed the region.

4. A method of entering input into a computing system according to claim 3, wherein inputs received via a region having been claimed by a sub-process are translated only by the sub-process having claimed that region of the sensing panel, or by a sub-process having a higher priority value than the sub-process having claimed the region of the sensing panel.

5. A method of entering input into a computing system according to claim 4, wherein once the claiming sub process is complete, the claimed region reverts to an unclaimed status.

6. A method according to claim 4, wherein all sub processes can process input movements entered via unclaimed regions of the sensing panel.

7. A method according to claim 3, wherein a claim for a region is successful if the region is unclaimed or if it has been previously claimed by a sub process having a lower priority than the sub process currently seeking the claim.

8. A computer-readable recording medium encoded with a computer program, the computer program for use in a system for entering input into a computing system, the system comprising a processor and associated memory device for storing the computer software including a series of instructions to cause the processor to carry out a method according to claim 1.

9. An input device for use with a computing system for entering input into the computing system, the input device comprising a sensing panel and a transmission component for transmitting detected input movements to a processor to identify an instruction signal corresponding to the detected input movement in accordance with the method according to claim 1.

10. A method according to claim 1, wherein the order of the priority value assigned to each sub process is dependent on:

(a) how the sub process was invoked;

(b) when the sub process was requested;

(c) an original position of the input movement which invoked the sub process on the sensing panel; and

(d) a mode requested for the sub process.

11. A method according to claim 1, wherein once a sub process has been assigned a priority, it is registered in a registration list which records data including sub process identification, modes, and priorities.

12. A method according to claim 11, wherein the registration list further records claimed regions.

13. An input system for a computing system, the input system comprising:

a sensing panel including an array of sensors for detecting input movements;

a processor for classifying each detected input movement as being of a particular type and translating each input movement to an instruction signal for transmission to the computing system; and

a knowledge database for consultation by the processor to identify the instruction signal corresponding to the detected input movement;

wherein translation of a detected input movement to an instruction signal involves a main process and one or more sub-processes, the main process and the one or more sub processes together form a hierarchical control structure in which the main process determines whether an input movement corresponds to a prompt to invoke a particular mode, and where a particular mode is indicated, the main process invokes a sub process in that mode

each sub process is assigned to translate one or more particular input movements into corresponding instruction signals by consulting the knowledge database,

the main process manages one or more sub processes by assigning a priority value such that a sub process having a minor priority value does not impede a sub process having a major priority value; and

the whole sensing panel functions as a single sensing area and the main process and one or more sub-processes can be invoked regardless of the location of the detected input movement on the sensing panel.

14. An input system according to claim 13, wherein each particular type of input movement is associated with operation of the sensing panel in any one of the following modes:

(a) keyboard modes;

(b) mouse modes;

(c) scripting modes;

17. An input system according to claim 15, wherein the sensors detect light patterns which are transformed into images and an input movement is detected when a first image differs from a subsequently formed second image.

18. An input system according to claim 13, further including a movement indicating device, wherein the input movements detected are the movements of the movement indicating device, the movement of which across the surface of the panel indicates an instruction signal to move in the direction indicated with the movement indicating device.

19. An input system according to claim 18, wherein an application of pressure to the movement indicating device causes an input movement which is interpreted by the processor as indicating an instruction signal to move downwards, and reducing the pressure applied to the movement indicating device causes an input movement which is interpreted by the processor as indicating an instruction signal to move upwards.

20. An input system according to claim 18, wherein the amount of pressure being applied to the movement indicating device is detected by reference to the size of an area of contact between the fingers or movement indicating device and the surface of the panel, or by reference to change in size of an area of contact between the fingers or movement indicating device and the surface of the panel.

21. An input system according to claim 13, wherein the sensing panel further includes a display layer for guiding user input.
