Gesture Feedback for Non-Sterile Medical Displays

A method of providing sterility-preserving feedback with respect to control or input gestures in a medical system, the method comprising the steps of:

• generating a threshold by using a presence detector and acquiring detection data which describe whether a medical input gesture reaches and/or crosses the threshold;
• triggering a sterility-preserving response to a positive detection by the presence detector, by using a computer which is connected to the presence detector;
• and
• providing, by using the computer, user guidance comprising a warning message if actual contact with a medical display has been detected by the presence detector or a touch screen display or a touch detector on the medical display.

A system, comprising:

• a data processing apparatus;
• a computer readable storage medium coupled to the data processing apparatus, the computer readable storage medium storing instructions that, when executed by the data processing apparatus, cause the data processing apparatus to perform operations, comprising:
• generating a threshold by using a presence detector and acquiring detection data representative of whether a medical input gesture crosses the threshold;
• triggering a sterility-preserving response to a positive detection by the presence detector by using the data processing apparatus which is operably connected to the presence detector;
• and
• providing, by using the data processing apparatus, the user guidance comprising a warning message when contact with a medical display has been detected by the presence detector.
