Abstract: A medical monitoring device may include a gesture control sensor for detecting gesture commands from users. The medical monitoring device may enable gesture control when it receives an identifier from a tag and the identifier is authenticated. The tag may include an RFID tag and/or a barcode. The identifier may be authenticated locally and/or by a remote device communicatively coupled to the medical monitoring device (e.g., over a network). Once gesture control is enabled, gestures by the user may be identified by the medical monitoring device, an action corresponding to the gesture may be determined, and the action may be performed. The gesture control sensor may be disabled manually or automatically when predetermined criteria are satisfied to prevent the gesture control sensor from receiving inadvertent commands.
