Finger lengths have fascinated scientific researchersfor a long time and people hardly notice different underpinningsof the relation between the shape and size of our body to thescientific meanings. The idea behind the shape of the palm lengthof the fingers indicates something profound about people sexualproclivities and vulnerability to certain diseases. In order toinvestigate and intervene in this health concern we measure thedigit ratio that is the ratio of the lengths of different digits. Theindex finger (2D) and ring finger (4D) for both the hands aretypically measured from the midpoint of the bottom crease wherethe finger joins the hand to the tip of the finger. This study usessmart phone camera to take the hand image and then measurerelative lengths of the second (2D) and the fourth (4D) fingers.Their ratio is calculated by dividing the length of the index fingerby the length of the ring finger of the hand. This finger readingforetells information of an individual´s psychology, motivations,health and social behavior such as homosexuality, cancers, musicalability, aggressive personality, passive personality traits,development disorder such as Dyslexia (which can be termed asliteracy deficiencies), athletic ability and dexterity innate abilityin key cognitive areas.
