Vehicle user interface unit for a vehicle electronic device

摘要

A vehicle user interface unit for a vehicle electronic device. The vehicle user interface unit includes a three-dimensional (“3D”) display unit having a display, and is configured to display an image for perception by a user as a virtual 3D image. The virtual 3D image is at least partially located in front of the display when the user observes the display. A display control unit is configured to control the generation of the image by the 3D display unit. The virtual 3D image includes a 3D object having at least two regions located in different spatial planes. Each region includes a plurality of interaction elements. An input unit is configured to detect the location of a user-controlled object and to interpret the detection of a predefined variation of the user-controlled object as a selection of one of the interaction elements in the virtual 3D image.

1. A vehicle user interface unit for a vehicle electronic device, comprising:
a three-dimensional (“3D”) display unit having a display, the 3D display unit being configured to display an image perceivable by a user as a virtual 3D image at least partially located in front of the display when the user observes the display; a display control unit configured to control generation of the image by the 3D display unit where the virtual 3D image includes a 3D object, the 3D object having at least two regions located in different spatial planes, each region of the at least two regions having interaction elements; a detector configured to determine a position of a user's head and determine a location of the virtual 3D image based on the determined position of the user's head; and a camera input unit configured to:
determine an angle along which the user perceives the display based on the determined position of the user's head and based on the determined location of the virtual 3D image;detect, from the determined perception of the user, a location of a finger of the user within a predetermined distance from at least one of the interaction elements;interpret as a selection of the at least one of the interaction elements, the detection of the location of the finger within the predetermined distance;provide an acoustical feedback to the user when the finger comes to within a predetermined distance of an element of the 3D object or when selection of one of the interaction elements is detected; andprovide an audio signal as the acoustical feedback, the audio signal having a frequency that changes according to the location of the finger.
