Abstract

Embodiments of a system and method for processing and recognizing non-contact types of human input to prevent contamination are generally described herein. In example embodiments, human input is captured, recognized, and used to provide active input for control or data entry into a user interface. The human input may be provided in variety of forms detectable by recognition techniques such as speech recognition, gesture recognition, identification recognition, and facial recognition. In one example, the human input recognition techniques are used in connection with a device cleaning workflow used to obtain data and human input during cleaning procedures while minimizing cross-contamination between the contaminated device or person and other objects or persons. In another example, the human input recognition techniques are used in connection with a device tracking workflow used to obtain data and human input while tracking interactions with and locations of the contaminated or uncontaminated device.

First claim
