Abstract

Claims (27)

1 . An apparatus for determining at least one intent of at least one user, the apparatus comprising:

at least one eye movement sensing device configured to sense at least one eye movement signal from the user, the eye movement signal being indicative of at least one eye movement of the user; and

at least one head movement sensing device configured to sense at least one head movement signal from the user, the head movement signal being indicative of at least one head movement of the user;

wherein the apparatus is configured to determine at least one degree of correlation between the eye movement signal and the head movement signal, wherein the apparatus is configured to determine at least one intent of the user based at least on the determined degree of correlation,

wherein the eye movement sensing device is configured to sense at least one bioelectrical signal from the user, the bioelectrical signal being indicative of at least one eye movement of the user,

wherein the apparatus is configured to distinguish between a plurality of different intents and to classify the intent of the user into a plurality of different classes based on one or more criteria that the determined degree of correlation must satisfy in order to be classified into the respective class,

wherein the apparatus comprises or is coupled to an electronic media device, wherein the apparatus is configured to provide at least one control input to control at least one function of the electronic media device based on the determined intent of the user, and

wherein the apparatus is configured to control, by the at least one control input, at least one of the following functions of the electronic media device: a volume, a light intensity, a 2D or 3D distribution of sound, an audio content, a spatial variance of one or more properties of an audio, one or more functions of a lighting device of the electronic media device, one or more functions of an audio device of the electronic media device, and activation/deactivation of the electronic media device.

2 . The apparatus according to claim 1 , wherein the bioelectrical signal is a biopotential signal.

3 . The apparatus according to claim 1 , further comprising at least one earpiece configured to be worn on the user's ear(s) and/or over the user's ear(s) and/or at least partially within a cavity of the user's ear(s), wherein the earpiece comprises at least the eye movement sensing device and/or the head movement sensing device.

4 . The apparatus according to claim 3 , wherein the earpiece comprises at least one eartip configured to be inserted at least partially into a cavity of the user's ear, wherein the eartip includes at least the eye movement sensing device, wherein the eartip is configured such that the eye movement sensing device is at least partially inserted into the cavity of the user's ear, when the eartip is inserted at least partially into the cavity of the user's ear.

5 . The apparatus according to claim 1 , wherein the apparatus is configured to classify the intent of the user by determining whether the determined degree of correlation satisfies at least one criterion.

6 . The apparatus according to claim 5 , wherein the apparatus is configured to determine whether the determined correlation is a natural correlation between the sensed eye movement and the sensed head movement of the user or an unnatural correlation between the sensed eye movement and the sensed head movement of the user according to at least one criterion to classify the intent of the user based thereon.

7 . The apparatus according to claim 1 , wherein the apparatus is configured to determine a natural correlation between the sensed eye movement and the sensed head movement of the user by determining a threshold representing a minimum degree of head movement of the user based on the sensed eye movement of the user and subsequently determining if the threshold is reached and/or surpassed by the sensed head movement.

8 . The apparatus according to claim 1 , wherein the apparatus is configured to determine a natural correlation between the sensed eye movement and the sensed head movement of the user by determining a direction of the sensed head movement of the user and a target direction of head movement of the user based on the sensed eye movement of the user and determining if the determined direction of the sensed head movement of the user and the target direction of head movement of the user substantially match and/or are within a target range.

9 . The apparatus according to claim 1 , wherein the apparatus is configured to determine a first intent, when the determined correlation satisfies at least one first criterion, and a second intent, when the determined correlation satisfies at least one second criterion, the first criterion differing from the second criterion and/or the first intent differing from the second intent.

10 . A method for determining at least one intent of at least one user using the apparatus according to claim 1 , the method comprising the following steps:

sensing at least one eye movement signal from the user using at least one eye movement sensing device the eye movement signal being indicative of at least one eye movement of the user, wherein the eye movement sensing device is configured to sense at least one bioelectrical signal from the user, the bioelectrical signal being indicative of at least one eye movement of the user;

sensing at least one head movement signal from the user using at least one head movement sensing device, the head movement signal being indicative of at least one head movement of the user;

determining at least one degree of correlation between the eye movement signal and the head movement signal;

determining at least one intent of the user based at least on the determined degree of correlation;

distinguishing between a plurality of different intents and classifying the intent of the user into a plurality of different classes based on one or more criteria that the determined degree of correlation must satisfy in order to be classified into the respective class; and

generating at least one control input to control at least one function of at least one electronic media device based on the determined intent of the user, wherein the apparatus comprises or is coupled to the electronic media device,

wherein the apparatus is configured to control, by the at least one control input, at least one of the following functions of the electronic media device: a volume, a light intensity, a 2D or 3D distribution of sound, an audio content, a spatial variance of one or more properties of an audio, one or more functions of a lighting device of the electronic media device, one or more functions of an audio device of the electronic media device, and activation/deactivation of the electronic media device.

11 . The method according to claim 10 , wherein the intent of the user is classified by determining whether the determined correlation is a natural correlation between the sensed eye movement and the sensed head movement of the user or an unnatural correlation between the sensed eye movement and the sensed head movement of the user.

12 . The method according to claim 10 , wherein a first intent is determined, when the determined correlation satisfies at least one first criterion, and a second intent is determined, when the determined correlation satisfies at least one second criterion, the first criterion differing from the second criterion and/or the first intent differing from the second intent.

13 . The apparatus according to claim 1 , wherein the bioelectrical signal is an electrooculographic (EOG) signal.
