Abstract
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.
Claims20
A method for reducing erroneous detection of input command gestures, the method comprising:
- detecting with a gesture sensor a presence of a human body part;
- storing a reference time value of when the detecting with the gesture sensor occurred;
- detecting with at least one validation sensor a presence of a human body part, wherein the at least one validation sensor has a detection volume that completely overlaps a detection volume of the gesture sensor;
- storing a further time value of when the detecting with the at least one validation sensor occurred;
- comparing the reference time value with the further time value to provide a difference value indicative of a time duration;
- and
- determining a valid occurrence of an input command gesture detected by the gesture sensor based on the difference value.
A system for reducing erroneous detection of input command gestures, the system comprising:
- a gesture sensor and at least one validation sensor, both operatively coupled to a control unit, wherein a detection volume of the at least one validation sensor completely overlaps a detection volume of the gesture sensor;
- wherein the system is configured to perform the steps comprising:
- detecting with the gesture sensor a presence of a human body part;
- storing in the control unit a reference time value of when the detecting with the gesture sensor occurred;
- detecting with the at least one validation sensor a presence of a human body part;
- storing in the control unit a further time value of when the detecting with the at least one validation sensor occurred;
- comparing by the control unit the reference time value with the further time value to provide a difference value indicative of a time duration;
- and
- determining by the control unit a valid occurrence of an input command gesture detected by the gesture sensor based on the difference value.
