Abstract

A method of obtaining a desired state in (22) a subject comprises measuring one or more physiological parameters of the subject (12), calculating, using the measured parameter (s), a value (38), determining if the calculated value (38) is to be modified, modifying the calculated value, if the determination is that the value is to be modified, and generating an output to the subject, the output being in proportion to the modified value (40). The step of modifying the calculated value, if the determination is that the value is to be modified, can comprise accessing a modification scheme and modifying the calculated value according, to the modification scheme. One method of modifying the calculated value comprises amplifying the calculated value.

Claims

1. A method of obtaining a desired state (22) in a subject (12) comprising:

measuring one or more physiological parameters of the subject (12),

calculating, using the measured parameter(s), a value (38),

determining if the calculated value (38) is to be modified,

modifying the calculated value (38), if the determination is that the value is to be modified, and

generating an output to the subject (12), the output being in proportion to the modified value (40).

2. A method according to claim 1, wherein the step of modifying the calculated value (38), if the determination is that the value (38) is to be modified, comprises accessing a modification scheme (26) and modifying the calculated value (38) according to the modification scheme (26).

3. A method according to claim 2, wherein the modification scheme (26) is in the form of a graph or look-up table.

4. A method according to claim 1, wherein the step of modifying the calculated value (38), if the determination is that the value (38) is to be modified, comprises amplifying or attenuating the calculated value (38).

5. A method according to claim 1, wherein the step of determining if the calculated value (38) is to be modified comprises comparing the calculated value (38) against a threshold (20).

6. A method according to claim 4, wherein the step of modifying the calculated value (38), if the determination is that the value (38) is to be modified, comprises amplifying the calculated value (38) if the calculated value (38) is beyond the threshold (20).

7. A method according to claim 1, and further comprising mapping the one or more measured physiological parameters of the subject (12) to a scale and wherein the calculated value (38) comprises a value on the scale.

8. A method according to claim 1, and further comprising determining the direction of movement of the calculated value (38), wherein the step of modifying the calculated value (38), if the determination is that the value (38) is to be modified, is dependent on the direction of movement of the value (38).

9. A system for obtaining a desired state in a subject (12) comprising:

one or more sensors (14) arranged to measure one or more physiological parameters of the subject (12),

a processor (16) arranged to calculate, using the measured parameter(s), a value (38), to determine if the calculated value (38) is to be modified, and to modify the calculated value (38), if the determination is that the value (38) is to be modified, and

one or more output devices (18) arranged to generate an output to the subject (12), the output being in proportion to the modified value (40).

10. A system according to claim 9, wherein the processor (16) is arranged, when modifying the calculated value (38), if the determination is that the value (38) is to be modified, to access a modification scheme (26) and to modify the calculated value (38) according to the modification scheme (26).

11. A system according to claim 10, wherein the modification scheme (26) is in the form of a graph or look-up table.

12. A system according to claim 9, wherein the processor (16) is arranged, when modifying the calculated value (38), if the determination is that the value (38) is to be modified, to amplify or attenuate the calculated value (38).

13. A system according to claim 9, wherein the processor (16) is arranged, when determining if the calculated value (38) is to be modified, to compare the calculated value (38) against a threshold (20).

14. A system according to claim 12, wherein the processor (16) is arranged, when modifying the calculated value (38), if the determination is that the value (38) is to be modified, to amplify the calculated value (38) if the calculated value (38) is beyond the threshold (20).

15. A system according to claim 9, wherein the processor (16) is further arranged to map the one or more measured physiological parameters of the subject (12) to a scale and wherein the calculated value (38) comprises a value on the scale.
