Abstract

A method for maintaining the relative position between a data capture device and an operator of the data capture device includes prompting the operator to arrange a data capture device to be in an optimal position relative to an operator of the device. Moreover, the method includes capturing authentication data of the operator with the data capture device while the operator uses data displayed on a screen of the data capture device, and determining whether the data capture device is in the optimal position relative to the operator while capturing authentication data of the operator. Furthermore, the method includes determining a displacement of the data capture device relative to the optimal position when the data capture device is in a position different than the optimal position, and shifting the data relative to the screen by applying the relative displacement to the data.
