Operating unit for a steering wheel of a motor vehicle and method for determining a position of a symbol display

A method for determining a position of a symbol display in an at least partially transparent operating unit for a steering wheel of a motor vehicle, the method comprising:

• determining a position of a symbol display unit comprising the symbol display in the motor vehicle;
• determining a target position for a visualization of a symbol using the symbol display relative to the symbol display unit;
• determining an average eye point when using the steering wheel relative to the symbol display unit;
• determining a distance and a viewing angle of the average eye point relative to the symbol display unit;
• and
• determining a position of the symbol display in the symbol display unit such that the visualization of the symbol using the symbol display, when viewed from the determined distance and the determined viewing angle from the average eye point, takes place at the target position for the visualization of the symbol, wherein
• the distance and the viewing angle of the average eye point relative to the symbol display unit is determined based on a predetermined mean value for setting the steering wheel position.
