First Claim
Patent Images
1. A method for identifying a user of a user interface device, the method comprising:
- at a processing device,a) receiving at least one signal from one or more sensors associated with the user interface device;
b) identifying a user of the user interface device based on the received at least one signal and previously stored user parameter informationc) determining if the identified user is different than the most recently authenticated user; and
d) outputting a signal that indicates a user operation issue if the user is determined to be different than the most recently authenticated user; and
repeating at a-d) after a predefined delay.

Abstract
Systems and methods uniquely identify the user of the keyboard. An example of the present invention includes sensors capable of detecting the interaction of a user caused by their touch, vibration, proximity, and actuation of key switches. Unique characteristics such as typing style, touch signature, tap strength, and others can be determined using the multi-sensor keyboard in ways not possible on a conventional mechanical keyboard. Further, it is also useful to know when a change of keyboard users has occurred for the purpose of infection prevention in healthcare settings where cross-contamination via computer keyboards is prevalent.
