Vein scanning device for automatic gesture and finger recognition
First Claim
1. A method for determining hand gestures by an electronic device, the method comprising:
- capturing one or more first images of one or more veins in a hand at a first time;
capturing one or more second images of the one or more veins in the hand at a second time, different from the first time;
determining a first hand pose based on the one or more first images, wherein determining the first hand pose includes correlating the one or more veins in the one or more first images to one or more joints of the hand;
determining a second hand pose based on the one or more second images, wherein determining the second hand pose includes correlating the one or more veins in the one or more second images to one or more joints of the hand; and
determining a gesture based on at least the first hand pose and the second hand pose.

Abstract
This relates to a device capable of automatically determining a user'"'"'s gesture and/or finger positions based on one or more properties of the user'"'"'s veins and methods for operation thereof. The device can include one or more sensors (e.g., a camera) to capture one or more images of the user'"'"'s hand. The device can convert the image(s) to digital representations and can correlate the digital image(s) of the veins to one or more poses. From the pose(s), the device can determine the user'"'"'s hand movements, and one or more gestures and/or finger positions can be determined from the hand movements. The device can interpret the gestures and/or finger positions as one or more input commands, and the device can perform an operation based on the input command(s). Examples of the disclosure include using the user input commands in virtual reality applications.

16. An electronic device comprising:
-
one or more sensors, the one or more sensors configured to capture one or more first images of one or more veins in a hand and capture one or more second images of the one or more veins in the hand; and a processor configured to; receive the captured one or more first images, receive the captured one or more second images, convert the captured one or more first images and the captured one or more second images to a first digital representation and a second digital representation, respectively, detect one or more differences between the first digital representation and the second digital representation, determine one or more hand movements based on the one or more differences, wherein the determination of the one or more hand movements includes correlating one or more veins in the one or more first images to one or more joints of the hand, determine one or more hand gestures based on the determined one or more hand movements, and perform one or more operations on the electronic device based on the determined one or more hand gestures. - View Dependent Claims (17, 18, 19, 20)
