Abstract

A method of controlling an influence on a user (14) in a rendering environment comprises: obtaining signal data (16) representing one or more physiological conditions of a user (14) in response to an influence caused by system feedback (13) of the rendering environment; obtaining data corresponding to a user'"'"'s desired emotional state (19,20;32-36), which data is based on the user'"'"'s self-reports and data representative of accompanying signal data (16) representing one or more physiological conditions of the user (14) over a last period before the accompanying self-report; —determining whether the desired emotional state (19,20;32-36) is reached; and if the state (19,20;32-36) is not reached, adapting the system feedback (16) provided by the rendering environment correspondingly.

Claims

1. Method of controlling an influence on a user (14) in a rendering environment, the method comprising:

obtaining signal data (16) representing one or more physiological conditions of a user (14) in response to an influence caused by system feedback (13) of the rendering environment;

obtaining data corresponding to a user'"'"'s desired emotional state (19,20;

32-36);

determining whether the desired emotional state (19,20;

32-36) is reached; and

if the state (19,20;

32-36) is not reached, adapting the system feedback (16) provided by the rendering environment correspondingly.

2. Method according to claim 1, wherein the data corresponding to a user'"'"'s desired emotional state (19,20;

32-36) include thresholds (28,29) corresponding to switch points at which the user (14) switches between emotional states.

3. Method according to claim 1, wherein, at least in a calibration mode, the user'"'"'s self-reports and data representative of accompanying signal data (16) representing one or more physiological conditions of the user (14) over a last period before the accompanying self-report are obtained and a level of at least one dimension of the system feedback (16) is constantly changed.

4. Method according to claim 3, wherein a next level of at least one dimension of the system feedback (16) is selected from a scanning sequence database.

5. Method according to claim 1, wherein the user'"'"'s self-reports and data representative of accompanying signal data (16) representing one or more physiological conditions of the user (14) over a last period before the accompanying self-report are stored in a database (24).

6. Method according to claim 1, wherein the user'"'"'s self-reports and data representative of accompanying signal data (16) representing one or more physiological conditions of the user (14) over a last period before the accompanying self-report are obtained in a calibration mode, in which they are used to train at least one classifier for predicting the user'"'"'s emotional state from at least one signal (16) representing one or more physiological conditions of the user (14).

7. Method according to claim 1, wherein the user'"'"'s self-reports and data representative of accompanying signal data (16) representing one or more physiological conditions of the user (14)over a last period before the accompanying self-report are obtained in a calibration mode, and wherein a switch is effected to an adaptive mode, in which the steps of determining whether the desired emotional state (19,20;

32-36) is reached and, if the state (19,20;

32-36) is not reached, adapting the system feedback (13) provided by the rendering environment correspondingly are carried out continuously.

8. Method according to claim 7, including remaining in the adaptive mode for as long as no new user'"'"'s reports are provided.

12. Computer program including a set of instructions capable, when incorporated in a machine-readable medium, of causing a system having information processing capabilities to perform a method according to claim 1.

9. Apparatus for controlling an emotionally adaptive system, the apparatus including:

an input/output unit (8) for obtaining signal data (16) representing one or more physiological conditions of a user (14) in response to an influence caused by system feedback (13) of the rendering environment;

a processor (2) for implementing an algorithm; and

memory (4) for a database (24), the algorithm enabling the apparatus to;

obtain data corresponding to a user'"'"'s desired emotional state (19,20;

32-36);

determine whether the desired emotional state (19,20;

32-36) is reached; and

if the state (19,20;

32-36) is not reached, adapt the system feedback (13) provided by the rendering environment correspondingly.

11. Emotionally adaptive system, comprising products (10-12) for rendering feedback effects and an apparatus (1) according to claim 9.
