1. A device comprising:

  • a signal transmission unit configured to transmit signals;

    a signal sensing unit configured to receive reflected signals, wherein the reflected signals represent at least the transmitted signals reflected by blood vessels in a body part of a user;

    one or more processors configured to;

    generate blood vessel data based on the reflected signals, wherein the blood vessel data represents information associated with 3 dimensional (3D) locations of the blood vessels of the body part,generate 3D coordinates from the blood vessel data, wherein the 3D coordinates represent a location of the body part,determine a line of sight representing a viewing direction, an orientation or a combination thereof of the user, andgenerate an image according to the line of sight; and

    an image output unit operably coupled to the one or more processors and configured to output the image according to the 3D coordinates and the line of sight, wherein the image is displayed at a display location associated with the 3D coordinates.
