Geometry of a hand and some examples of measurements that can be taken by hand geometry reading devices. [1] A hand geometry reading device with pegs to control the placement of the hand. Angled mirror on the left reflects the side view image of the hand to the camera. A CCD camera is beneath the keypad to take the top view image of the hand ...
Iris scanner in action to identify people. A biometric device is a security identification and authentication device. Such devices use automated methods of verifying or recognising the identity of a living person based on a physiological or behavioral characteristic.
Handwritten biometrics can be split into two main categories: Static: In this mode, users writes on paper, digitize it through an optical scanner or a camera, and the biometric system recognizes the text analyzing its shape.
Accordingly, "the biometric system is the absolute political weapon of our era" and a form of "soft control". [26] The theoretician David Lyon showed that during the past two decades biometric systems have penetrated the civilian market, and blurred the lines between governmental forms of control and private corporate control.

Biometric systems based on fingerprints can be fooled with a dummy finger fitted with a copied fingerprint; voice and facial characteristic-based systems can be fooled by recordings and high-resolution images. The finger vein identification system is much harder to fool because it can only authenticate the finger of a living person. [13] [12]
A child's hand location and movement being detected by a gesture recognition algorithm. Gesture recognition is an area of research and development in computer science and language technology concerned with the recognition and interpretation of human gestures.
Hand coding is a mechanism used by the Wikimedia Foundation to help analyse the impact our software and changes have on the community. The intent is to provide a way for editors to use their judgment to evaluate the data: editors are far better at working out the impact changes will have than we are, because editors are the ones who will have to deal with such changes.
In computational geometry, numerous algorithms are proposed for computing the convex hull of a finite set of points, with various computational complexities. Computing the convex hull means that a non-ambiguous and efficient representation of the required convex shape is constructed.
