US 2019/0102082 A1 · TOUCH-SENSITIVE ALPHANUMERIC USER INTERFACE

Abstract

A touch-sensitive alphanumeric user interface for a vehicle. The touch-sensitive alphanumeric user interface includes a touchpad, a touchpad interface unit, a display interface unit and a display. The touchpad is integrated in a steering wheel of the vehicle and obtains coordinates of a trajectory performed by a finger of a user of the vehicle. The touchpad interface unit determines that a finger movement, identified from the first coordinates, is an arcuate movement, and based on the determination, issues arcuate movement instructions to the display interface unit. The display interface unit renders a visualization of alphanumeric choices, arranged in a circular pattern, determines a selected alphanumeric choice from the alphanumeric choices, based on the arcuate movement instructions, and renders the selected alphanumeric choice to be highlighted. The display, which is spatially separate from the touchpad, displays the rendered visualization of the alphanumeric choices and of the selected alphanumeric choice.

Dependent claims

A touch-sensitive alphanumeric user interface for a vehicle, comprising:

a first touchpad, integrated in a steering wheel of the vehicle, and configured to obtain first coordinates of a first trajectory performed by a finger of a user of the vehicle;
a touchpad interface unit configured to:
make a first determination that a first finger movement, identified from the first coordinates, is an arcuate movement, and based on the first determination, issue arcuate movement instructions to a display interface unit;
the display interface unit configured to:
render a visualization of a plurality of alphanumeric choices, arranged in a circular pattern;
determine a selected alphanumeric choice from the plurality of alphanumeric choices, based on the arcuate movement instructions;
render the selected alphanumeric choice to be highlighted;
and
a display, spatially separate from the first touchpad, configured to:
display the rendered visualization of the plurality of alphanumeric choices and of the selected alphanumeric choice.
