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.

15. A method of operating a device, the device having a signal transmitter and a signal receiver, the method comprising:
-
operating the signal transmitter to transmit signals; receiving reflected signals using the signal receiver, wherein the reflected signals represent at least the transmitted signals reflected by blood vessels in blood vessels in a body part of a user; generating 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; generating 3D coordinates from the blood vessel data, wherein the 3D coordinates represents a location of the body part; determining a line of sight for representing a viewing direction, an orientation or a combination thereof of the user; generating an image according to the line of sight; and outputting the image according to the 3D coordinates, wherein the image is displayed at a display location that is fixed relative to the 3D coordinates. - View Dependent Claims (16, 17)
