Abstract

Biometric data are produced in response to user input to an interactive display. The user input occurs when the interactive display senses a user input proximate to an interactive display surface that is able to respond to simultaneous multiple inputs. A detection signal based on a user input is processed to identify biometric indicia associated with the user input. User input can be by any biometric entity, such as an animal—not just by a human. Based on the biometric indicia identified, user biometric data are produced. The user biometric data includes parameters describing physical characteristics associated with the portion of the user that provided the user input. The biometric data can be compared to stored biometric data associated with a specific user and/or user profile, e.g., to enable access by the user to an account, and can also be employed to provide other functions, such sizing information, to applications.

The method of claim 1, wherein the interactive display is configured for transmitting non-visible light through a first side of the surface and receiving a portion of the non-visible light that is reflected back through the surface from objects that are proximate to a second side of the surface and wherein the step of generating a detection signal based on the user input received further comprises the step of producing an image map of non-visible light intensity that is based on the non-visible light reflected back through the interactive display surface from the portion of the user that is proximate to the second side of the interactive display surface.

4. The method of claim 3, wherein the image map of non-visible intensity is processed to produce three-dimensional image information associated with the portion of the user.

5.

(b) determining at least one biometric parameter from the detection signal; and

(c) generating a user biometric archetype that includes the at least one biometric parameter that was determined, the user biometric archetype comprising the biometric data.
