Embodiments of the present invention provide for a system and method for reducing erroneous detection of input command gestures. The method is performed by the system and includes storing a reference time value of when a presence of a human body part is detected by a first sensor and storing a further time value of when a presence of a human body part is detected by a second sensor. The reference time value and further time value are compared to provide a difference value which is used to determine a valid occurrence of an input command gesture.
