A lamp system for a vehicle with two headlamps, comprising: - at least one light source configured to generate light; - a transparent display configured to allow at least a portion of the light to pass through the transparent display; wherein the at least one light source and the transparent display is included in at least one of the headlamps of the vehicle; characterized in that the system comprises - a gaze-sensing module for sensing a driver's gaze, - an interface unit configured to receive driver gaze information sensed by said gaze-sensing module; and - a processor configured to: receive through the interface unit the driver's gaze information, control the transparent display to display, on a projection surface using the light in an area of the driver's gaze sensed by the gaze-sensing module in a forward driving direction of the vehicle, at least one of information related to the vehicle and driving conditions for the vehicle, the processor is further configured to: change an area of the transparent display, where design or a text is formed, according to the driver's gaze information, so that the formed design or text is displayed in the area corresponding to the driver's gaze on the projection surface, wherein there is a difference in color, brightness or light intensity between light emitted outward through the area of the transparent display in which the design or text is formed and light emitted outward through an other area of the transparent display in which neither design nor text is formed, the processor is configured to display at least one of the information related to the vehicle and the driving conditions for the vehicle in an area corresponding to a driver's gaze sensed by the gaze-sensing module built as a camera disposed in the vehicle. - at least one light source configured to generate light; - a transparent display configured to allow at least a portion of the light to pass through the transparent display; wherein the at least one light source and the transparent display is included in at least one of the headlamps of the vehicle; characterized in that the system comprises - a gaze-sensing module for sensing a driver's gaze, wherein the at least one light source and the transparent display is included in at least one of the headlamps of the vehicle; characterized in that the system comprises - a gaze-sensing module for sensing a driver's gaze, - a gaze-sensing module for sensing a driver's gaze, - an interface unit configured to receive driver gaze information sensed by said gaze-sensing module; and - a processor configured to: receive through the interface unit the driver's gaze information, control the transparent display to display, on a projection surface using the light in an area of the driver's gaze sensed by the gaze-sensing module in a forward driving direction of the vehicle, at least one of information related to the vehicle and driving conditions for the vehicle, the processor is further configured to: change an area of the transparent display, where design or a text is formed, according to the driver's gaze information, so that the formed design or text is displayed in the area corresponding to the driver's gaze on the projection surface, wherein there is a difference in color, brightness or light intensity between light emitted outward through the area of the transparent display in which the design or text is formed and light emitted outward through an other area of the transparent display in which neither design nor text is formed, the processor is configured to display at least one of the information related to the vehicle and the driving conditions for the vehicle in an area corresponding to a driver's gaze sensed by the gaze-sensing module built as a camera disposed in the vehicle. receive through the interface unit the driver's gaze information, control the transparent display to display, on a projection surface using the light in an area of the driver's gaze sensed by the gaze-sensing module in a forward driving direction of the vehicle, at least one of information related to the vehicle and driving conditions for the vehicle, the processor is further configured to: change an area of the transparent display, where design or a text is formed, according to the driver's gaze information, so that the formed design or text is displayed in the area corresponding to the driver's gaze on the projection surface, wherein there is a difference in color, brightness or light intensity between light emitted outward through the area of the transparent display in which the design or text is formed and light emitted outward through an other area of the transparent display in which neither design nor text is formed, the processor is configured to display at least one of the information related to the vehicle and the driving conditions for the vehicle in an area corresponding to a driver's gaze sensed by the gaze-sensing module built as a camera disposed in the vehicle.
