An image displaying system is provided, in which a touch panel comprises a transparent substrate with a first surface and a second surface opposite to the first surface, a black matrix, a protection layer, at least one first transparent electrode, a planarization layer, a color filter and a common electrode. The method includes: determining a position of at least one of the objects within the animal housing; displaying the position of the at least one object on a map of the animal housing on a visual display device; validating the determined position before displaying the position. The position of the object can be calculated in various ways including calculating a position of the object based on a phase delay of the reflected rays, or based on an intensity of the reflected rays, or based on an incidence angle of the reflected rays. Further, the connector may be configured to extend between the elongated members and the patient when the connector is implanted in a patient.
