Love tester machine

A love tester machine (also called "love meter" or "love teller") is a type of amusement personality tester machine, which upon receiving credit tries to rate the subject's sex appeal, love abilities or romantic feelings for someone. Many love testers measure the moisture on the skin surface of the subject's hands by electrically testing the skin conductance and rates accordingly. Others measure the temperature of the skin. However some machines just use a random generator. Love meters could be found in penny arcades, and can be seen in modern video arcades, amusement parks, in bars and restaurants. Such vending machines are for amusement purposes only and do not actually give a real result. Nintendo, in their early years, once created a Love Tester.
Digital versions.
"" includes a simulation of a real world love meter. Similar games can also be found on the Internet or as software applications. Software love testers are based on randomness, on various user inputs or on a questionnaire and an algorithm. Only serious surveys and analyses can thereby aim to give a real result.
