1. A computer implemented method for obtaining biometric data of a user and for using the biometric data to identify a size of an article of clothing that fits the user, wherein the biometric data is based on a user input to an interactive display that is able to simultaneously detect inputs at a plurality of locations proximate to a surface of the interactive display and which is employed for displaying images and detecting the user input, the method being performed by a computing system that includes the interactive display and comprising the following: receiving a user input, the user input being provided by detecting the input from a portion of a user positioned proximate to the surface of the interactive display, wherein the user is a biological entity that is not limited to being a human; generating a detection signal based on the user input received; processing the detection signal to identify biometric indicia associated with the user input; producing biometric data for the user based on the identified biometric indicia, the biometric data including at least one parameter describing one or more physical characteristics associated with the portion of the user that provided the user input; and identifying and displaying, at the interactive display, an attribute of an article of clothing that is sized to fit the user, based on the produced biometric data.
