Gesture recognition systems and devices for low and no light conditions
First Claim
1. A system, comprising:
- a thermographic camera having a first field of view, the thermographic camera to capture an infrared image within the first field of view;
an optical camera having a second field of view, the optical camera to detect an optical image, wherein the first field of view and the second field of view are substantially the same; and
a processor coupled to the thermographic camera, the processor to;
receive the infrared image from the thermographic camera;
receive the optical image from the optical camera;
determine whether a light condition of the optical image is a normal light condition, a low light condition, or a no light condition;
in response to the low light condition or the no light condition;
detect infrared radiation in the infrared image;
define a first readable zone within the infrared image, wherein the first readable zone is a portion of the first field of view that includes an image of a body part of a user;
identify a first gesture made by the user based on the infrared radiation within the first readable zone to obtain first gesture information; and
execute a first gesture recognition command associated with the first gesture information; and
in response to the normal light condition;
define a second readable zone within the optical image associated, wherein the second readable zone is a portion of the second field of view that includes the image of the body part of the user;
identify a second gesture made by the user within the second readable zone using optical recognition to obtain second gesture information; and
execute a second gesture recognition command associated with the second gesture information.

Abstract
Gesture recognition systems for detecting gesture commands in light conditions and in dark conditions including a computing system having a processor and a thermographic camera configured to detect infrared radiation from a gesture made by a user and communicate gesture image information to the processor for carrying out a computer-readable gesture command are shown and described. In some examples, the computing system and the thermographic camera are supported on an eyewear article frame. In some other examples, the computing system and the thermographic camera are components of a mobile device. In even other examples, the computing system and the thermographic camera are components of a desk top computer or a laptop computer.

11. A system, comprising:
a processor to; receive an infrared image from a thermographic camera; receive an optical image from an optical camera; determine whether a light condition of the optical image is a normal light condition, a low light condition, or a no light condition; in response to the low light condition or the no light condition; detect infrared radiation in the infrared image; define a first readable zone within the infrared image, wherein the first readable zone is a portion of a first field of view that includes an image of a body part of a user; identify a first gesture made by the user based on the infrared radiation within the first readable zone to obtain first gesture information; and execute a first gesture recognition command associated with the first gesture information; and in response to the normal light condition; define a second readable zone within the optical image associated, wherein the second readable zone is a portion of a second field of view that includes the image of the body part of the user; identify a second gesture made by the user within the second readable zone using optical recognition to obtain second gesture information; and execute a second gesture recognition command associated with the second gesture information. - View Dependent Claims (12, 13, 14, 15, 16)

17. A non-transitory computer-readable medium storing instructions to cause a processing device to:
-
receive an infrared image from a thermographic camera; receive an optical image from an optical camera; determine whether a light condition of the optical image is a normal light condition, a low light condition, or a no light condition; in response to the low light condition or the no light condition; detect infrared radiation in the infrared image; define a first readable zone within the infrared image, wherein the first readable zone is a portion of a field of view that includes an image of a body part of a user; identify a first gesture made by the user based on the infrared radiation within the first readable zone to obtain first gesture information; and execute a first gesture recognition command associated with the first gesture information; and in response to the normal light condition; define a second readable zone within the optical image associated, wherein the second readable zone is a portion of a second field of view that includes the image of the body part of the user; identify a second gesture made by the user within the second readable zone using optical recognition to obtain second gesture information; and execute a second gesture recognition command associated with the second gesture information. - View Dependent Claims (18)
