The virtual object indicator having dual image sensors for an electronic device comprises a housing to receive component therein. A user finger motion detecting device having the dual image sensors is attached on an upper surface of the housing for detection the motion of user finger. A controller is received in the housing for generating a control signal in responsive to the user finger motion detection, wherein the images captured by at least one of the dual image sensors is analyzed to drive a virtual object on a display of the electronic device, a communication interface is coupled to the controller for communication with the electronic device.
