Abstract

A method and system include controlling, by a control unit, a printer to form one or more tactile features on a surface of a component. Said controlling includes varying a speed of a print head of the printer to vary one or more attributes of the one or more tactile features. In at least one example, said varying the speed includes varying the speed of the print head of the printer during a single pass of the print head in relation to the surface of the component.

First claim

What is claimed is:

1 . A method comprising:
creating, by a control unit, a desired output display that includes one or more tactile features on a surface of a component through unit vector mapping, wherein said creating comprises: (a) providing, by the control unit, a unit vector map of the surface of the component in a two dimensional plane, and (b) unit vector mesh unwrapping and image texturing in conjunction with pixel clustering in relation to a speed of a print head of a printer; controlling, by the control unit, the printer to form the one or more tactile features on the surface of the component, wherein said controlling comprises varying the speed of the print head of the printer to vary one or more attributes of the one or more tactile features.

2 . The method of claim 1 , wherein the one or more tactile features comprise a plurality of tactile features, and wherein at least two of the plurality of tactile features differ in relation to the one or more attributes.

3 . The method of claim 1 , wherein said varying the speed comprises varying the speed of the print head of the printer during a single pass of the print head in relation to the surface of the component.

4 . The method of claim 1 , wherein the attributes comprise one or both of height or width.

5 . The method of claim 4 , wherein said varying the speed comprises reducing the speed of the print head to form the one or more tactile features having an increased height.

6 . The method of claim 5 , wherein the one or more tactile features have a reduced width.

7 . The method of claim 4 , wherein said varying the speed comprises increasing the speed of the print head to form the one or more tactile features having an increased width.

8 . The method of claim 7 , wherein the one or more tactile features having a reduced height.

9 . The method of claim 1 , wherein said controlling further comprises jetting ink from one or more nozzles of the print head at a constant print frequency.

10 . The method of claim 1 , wherein the component is on or within a vehicle, and wherein the surface is curved.

11 . A system comprising:
a printer including a print head; and a control unit configured to:
provide a unit vector map of a surface of a component in a two-dimensional plane,
create a desired output display that includes one or more tactile features on the surface of the component through the unit vector map, wherein the control unit is configured to create the desired output display through unit vector mesh unwrapping and image texturing in conjunction with pixel clustering in relation to a speed of the print head, and
control the printer to form the one or more tactile features on the surface of the component,
wherein the control unit is configured to vary the speed of the print head of the printer to vary one or more attributes of the one or more tactile features.

12 . The system of claim 11 , wherein the one or more tactile features comprise a plurality of tactile features, and wherein at least two of the plurality of tactile features differ in relation to the one or more attributes.

13 . The system of claim 11 , wherein the control unit is configured to vary the speed of the print head of the printer during a single pass of the print head in relation to the surface of the component.

14 . The system of claim 11 , wherein the attributes comprise one or both of height or width, wherein the control unit is configured to vary the speed by (a) reducing the speed of the print head to form the one or more tactile features having an increased height, and (b) increasing the speed of the print head to form the one or more tactile features having an increased width.

15 . The system of claim 11 , wherein the control unit is configured to control the printer by jetting ink from one or more nozzles of the print head at a constant print frequency.

16 . The system of claim 11 , wherein the component is on or within a vehicle, and wherein the surface is curved.

17 . A method comprising:
creating, by a control unit, a desired output display that includes tactile features on a surface of a component through unit vector mapping, wherein said creating comprises: (a) providing, by the control unit, a unit vector map of the surface of the component in a two dimensional plane, and (b) unit vector mesh unwrapping and image texturing in conjunction with pixel clustering in relation to a speed of a print head of a printer; controlling, by the control unit, the printer to form the tactile features on the surface of the component, wherein said controlling comprises varying the speed of the print head of the printer during a single pass to vary one on or both of height or width of the plurality of tactile features, wherein at least two of the plurality of tactile features differ in relation to one or both of the height or the width, said varying the speed comprises:
reducing the speed of the print head to form at least one of the plurality of tactile features having an increased height, and
increasing the speed of the print head to form at least one of the plurality of tactile features having an increased width.

18 . The method of claim 17 , further comprising jetting ink from one or more nozzles of the print head at a constant print frequency.

19 . The method of claim 17 , wherein the component is on or within a vehicle.

20 . The method of claim 19 , and wherein the surface is curved.
