Abstract:
A kiosk comprises: a motion sensor; electronics; and a speaker. The motion sensor senses a customer adjacent to the kiosk. The electronics, which are communicatively coupled to the sensor, determine if the customer has lingered by the kiosk for a period of time. The speaker, which is communicatively coupled to the electronics, emits an aural greeting if it is determined that the customer has not lingered.
