System and method for touchless switch interface

摘要

A method and system for guiding a trigger agent to activate a touchless switch having a proximity sensor and a plurality of activatable indicator lights. The method comprises detecting the trigger agent within a proximity threshold, activating at least one of the indicator lights according to a first indicator format, detecting a continuing presence of the trigger agent to progressively activate additional indicator lights as the trigger agent continues within the proximity threshold, detecting a retracting movement of the trigger agent away from the proximity sensor to progressively de-activate the activated indicator lights as the trigger agent retracts, and in response to detecting that the trigger agent has reached an activation time threshold, activating the touchless switch while activating the indicator lights according to a second indicator format.

1. A method for guiding a trigger agent to activate a touchless switch having a proximity sensor and a plurality of activatable indicator lights, the touchless switch having an unactivated state and an activated state, the method comprising:
detecting that the trigger agent is within a proximity threshold of the proximity sensor while the touchless switch remains in the unactivated state; in response to the detecting, activating at least one of the plurality of indicator lights while the touchless switch remains in the unactivated state; progressively activating additional ones of the plurality of indicator lights as the presence of the trigger agent continues within said proximity threshold of the proximity sensor while the touchless switch remains in the unactivated state; in response to detecting a retracting movement of the trigger agent away from the proximity sensor, progressively de-activating the activated ones of the indicator lights as the trigger agent progresses away from the proximity sensor while the touchless switch remains in the unactivated state; and placing the touchless switch in the activated state in response to detecting that the continuing presence of the trigger agent has reached an activation time threshold.
