Summary
A gaze-based hiding visibility
PIN-Entry technique comprises a four horizontal array of objects such as digits
and symbols. Each row contains five objects. First and third row comprises
array of digits from 0 to 9 (buttons are in disabled state) which are in random
order. Second and fourth row comprises with another array of numerous familiar
symbols such as $ and @ (buttons are in enabled state) which are also in random
order and both rows are responsible for first and third row objects. This new
technique needs four rounds. All rounds are PIN-entry rounds, in which the ith
digit of the PIN is entered in the ith round for i = 1, 2, 3, 4. In each of
these rounds, the technique is given a random array of objects; user enters PIN
digits by press the symbols collocated to PIN digits, instead of pressing
digits directly. Additionally, the objects get vanishes or hides when the user
presses button and generates another random order of objects for next round
when the user releases button. For example, if the PIN is 2371, the user
recognizes @ is collocated with the first digit of the PIN, 2. User presses the
symbol @ for first PIN digit. The objects get vanishes or hides when the user
presses the symbol @ button and generates another random order of objects for
second round when the user releases button. The same PIN-Entry method is
continues for remaining three rounds.
