Apparatus and method for controlling display of hologram, vehicle system

A hologram display control method, the method comprising:

• turning on a hologram display control depending on an input signal of a user;
• projecting a first hologram image corresponding to an image of a manipulating device of a steering wheel onto a first area predefined based on a space coordinate system of a vehicle, when the hologram display control is turned on;
• recognizing a set operation of the user in a second area predefined for operation recognition with respect to button manipulation in the first hologram image;
• recognizing a manipulation button in the first hologram image based on a location at which the set operation of the user is recognized;
• and
• transmitting a control signal to a driving device of the vehicle, the driving device operated by the recognized manipulation button,
• wherein the recognizing of the manipulation button includes:
• comparing coordinate information corresponding to a location of each button in the first hologram image with coordinate information related to a location at which the set operation is recognized in the second area;
• and
• recognizing the manipulation button depending on the comparison result,
• wherein the hologram device includes a lenticular display, and the first hologram image is projected at a location defined based on one or more of a panel size, a resolution, a pixel structure, a pixel pitch, a viewing distance, a focal length, a viewing distance based on both eyes, a lens pitch, and a viewing angle of the lenticular display, and
• wherein the location onto which the first hologram image is projected is defined as a location of an upper end portion or a center of the steering wheel.

A vehicle system comprising:

• one or more driving devices driven by a manipulating device included in a steering wheel of a vehicle;
• and
• a hologram display control apparatus configured to project hologram image corresponding to an image of the manipulating device of the steering wheel onto a first area predefined based on a space coordinate system of the vehicle after a hologram display control is turned on depending on an input signal of a user, to recognize a manipulation button in the hologram image depending on whether a set operation of the user is recognized in a second area predefined to include the first area, and to transmit a control signal to the driving devices driven by the recognized manipulation button,
• wherein the manipulation button is recognized by comparing coordinate information corresponding to a location of each button in the first hologram image with coordinate information related to a location at which the set operation is recognized in the second area,
• wherein the hologram display control apparatus includes a lenticular display, and projects the first hologram image at a location defined based on one or more of a panel size, a resolution, a pixel structure, a pixel pitch, a viewing distance, a focal length, a viewing distance based on both eyes, a lens pitch, and a viewing angle of the lenticular display, and
• wherein the location onto which the first hologram image is projected is defined as a location of an upper end portion or a center of the steering wheel.
