Viable hand geometry devices have been manufactured since the early 1970s, making hand geometry the first biometric to find widespread computerized use. [4] Robert Miller realized the distinctive features of hand sizes and shapes could be used for identification and patented the first automated hand geometry device at the Stanford Research Institute in 1971.
Examples include, but are not limited to fingerprint, [2] palm veins, face recognition, DNA, palm print, hand geometry, iris recognition, retina, odor/scent, voice, shape of ears and gait. Behavioral characteristics are related to the pattern of behavior of a person, including but not limited to mouse movement , [ 3 ] typing rhythm , gait ...
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs.A few other vertebrates such as the koala (which has two opposable thumbs on each "hand" and fingerprints extremely similar to human fingerprints) are often described as having "hands" instead of paws on their front limbs.
Charlemagne holds a sword in his proper right hand, on the "viewer's left", and an orb in his proper left hand, on the "viewer's right". Statue holding a sword in its proper right hand. Proper right and proper left are conceptual terms used to unambiguously convey relative direction when describing an image or other object.
Therefore each hand can represent the digits 0-9, rather than the usual 0-5. The two hands combine to represent two digits; the right hand is the ones place, and the left hand is the tens place. This way, any number from 0 to 99 can be shown, and it's possible to count up to 99 instead of just 10.
A non-flipped image of a right-handed Cartesian coordinate system, illustrating the x (right-left), y (forward-backward) and z (up-down) axes relative to a human being.Body relative directions (also known as egocentric coordinates) [1] are geometrical orientations relative to a body such as a human person's body or a road sign.

Two enantiomers of a generic amino acid that is chiral. Chirality (/ k aɪ ˈ r æ l ɪ t i /) is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χείρ (kheir), "hand", a familiar chiral object.
