Abstract

Claims (42)

1 . A method comprising:

receiving, by a computer system having at least one processor, a first set of signals from a first sensor, the first set of signals representing information captured from an environment of the computer system in a first field of view associated with the first sensor, wherein the first sensor is a video camera;

receiving, by the computer system, a second set of signals from at least one second sensor, the second set of signals representing information captured from an environment of the computer system in a second field of view associated with the second sensor, wherein the second field of view is wider than the first field of view, and wherein the second sensor is a radio frequency (RF) radar sensor;

receiving, by the computer system a third set of signals from at least one third sensor, the third set of signals representing information captured from an environment of the computer system in a third field of view associated with the third sensor, wherein the third field of view is wider than the second field of view, and wherein the third sensor is an ultrasound sensor;

processing, by the computer system, the first, second, and third sets of signals to create a representation of an effective field of view that is wider than the first field of view and the second field of view; and

detecting, by the computer system, the presence of at least one person within the effective field of view based on the representation.

2 . The method of claim 1 , further comprising:

in response to detecting the presence of the person within the effective field of view based on the representation, determining that the person is an authorized user based on the first set of signals; and

in response to determining that the person is a registered user, operating the computer system at a normal security level.

3 . The method of claim 1 , further comprising:

in response to detecting the presence of the person within the effective field of view based on the representation, determining that the person is either not an authenticated user or is of unknown authentication status based on the first set of signals; and

in response to determining, operating the computer system at a heightened security level including one or more security restrictions not included in a normal security level.

4 . The method of claim 3 , wherein operating the computer system at a heightened security level includes notifying an authenticated user of the computer system of the presence of the detected person.

5 . The method of claim 3 , wherein operating the computer system at a heightened security level includes obfuscating portions of a display of the computer system that can be seen by the detected person based on the first, second, and third sets of signals.

6 . A system comprising:

a computer system including at least one processor and a memory, and configured to perform operations including:

receiving, by a computer system having at least one processor, a first set of signals from a first sensor, the first set of signals representing information captured from an environment of the computer system in a first field of view associated with the first sensor, wherein the first sensor is a video camera;

receiving, by the computer system, a second set of signals from at least one second sensor, the second set of signals representing information captured from an environment of the computer system in a second field of view associated with the second sensor, wherein the second field of view is wider than the first field of view, and wherein the second sensor is a radio frequency (RF) radar sensor;

receiving, by the computer system a third set of signals from at least one third sensor, the third set of signals representing information captured from an environment of the computer system in a third field of view associated with the third sensor, wherein the third field of view is wider than the second field of view, and wherein the third sensor is an ultrasound sensor;

processing, by the computer system, the first, second, and third sets of signals to create a representation of an effective field of view that is wider than the first field of view and the second field of view; and

detecting, by the computer system, the presence of at least one person within the effective field of view based on the representation.

7 . The system of claim 6 , the operations further comprising:

in response to detecting the presence of the person within the effective field of view based on the representation, determining that the person is an authorized user based on the first set of signals; and

in response to determining that the person is a registered user, operating the computer system at a normal security level.

8 . The system of claim 6 , the operations further comprising:

in response to detecting the presence of the person within the effective field of view based on the representation, determining that the person is either not an authenticated user or is of unknown authentication status based on the first set of signals; and

in response to determining, operating the computer system at a heightened security level including one or more security restrictions not included in a normal security level.

9 . The system of claim 8 , wherein operating the computer system at a heightened security level includes notifying an authenticated user of the computer system of the presence of the detected person.

10 . The system of claim 8 , wherein operating the computer system at a heightened security level includes obfuscating portions of a display of the computer system that can be seen by the detected person based on the first and second sets of signals.

11 . An article of manufacture comprising a non-transitory, computer-readable medium having computer-executable instructions thereon that, when executed by a processor of a computer system, cause the processor to perform operations comprising:

receiving a first set of signals from a first sensor, the first set of signals representing information captured from an environment of the computer system in a first field of view associated with the first sensor, wherein the first sensor is a video camera;

receiving a second set of signals from at least one second sensor, the second set of signals representing information captured from an environment of the computer system in a second field of view associated with the second sensor, wherein the second field of view is wider than the first field of view, and wherein the second sensor is a radio frequency (RF) radar sensor;

receiving, by the computer system a third set of signals from at least one third sensor, the third set of signals representing information captured from an environment of the computer system in a third field of view associated with the third sensor, wherein the third field of view is wider than the second field of view, and wherein the third sensor is an ultrasound sensor;

processing the first, second, and third sets of signals to create a representation of an effective field of view that is wider than the first field of view and the second field of view; and

detecting the presence of at least one person within the effective field of view based on the representation.

12 . The article of claim 11 , the operations further comprising:

in response to detecting the presence of the person within the effective field of view based on the representation, determining that the person is an authorized user based on the first set of signals; and

in response to determining that the person is a registered user, operating the computer system at a normal security level.

13 . The article of claim 11 , the operations further comprising:

in response to detecting the presence of the person within the effective field of view based on the representation, determining that the person is either not an authenticated user or is of unknown authentication status based on the first set of signals; and

in response to determining, operating the computer system at a heightened security level including one or more security restrictions not included in a normal security level.

14 . The article of claim 13 , wherein operating the computer system at a heightened security level includes notifying an authenticated user of the computer system of the presence of the detected person.
