Abstract

This case concerns applications of my Reconfigurable Tactile Display (RTD) invention, particularly illustrating method and apparatus in which there is no rigid connection between a projector/electro-optical sensor unit, and a screen and control surface unit used to display data and receive user touch or control inputs. In many embodiments, elimination of this rigid connection constraint allows applications where heretofore it has been difficult to provide workable or useful human interface systems. One example is in the headrest of an automobile, while another is a hospital bed where the invention provides a lightweight and very easy to clean input and viewing device for the patient.

Claims

1. A method for providing video images and an interface thereto for persons in a vehicle seated behind a seat in front of them, comprising the steps of;

providing a video image projector in the seat ahead of said person;

projecting data from the projector is the onto a screen associated with the seat or the head rest of the seat ahead of the person;

sensing information concerning finger or control location on the screen; and

determining from said information, controlling images projected by said projector.

2. A method according to claim 1 wherein said images are obtained via the Internet.

3. A method according to claim 1 wherein said screen is plastic.

4. A method according to claim 1 wherein the surface of the screen is curved in at least some areas.

5. A method for presenting a larger size video image than would normally be possible in a constrained housing area in which physical controls are also present, comprising the steps of:

providing physical control details such as knobs or switches within the screen area of a screen substantially occupying said constrained housing area, and

displaying an image which is viewable both around and within said control details, such that an observer of said image perceives an adequate view even though relatively small portions of the image are blocked by portions of said physical control details, wherein said constrained housing area is a center stack of a motor vehicle.

6. A method for providing increased visibility of projected labels on control panels such as those of a vehicle instrument panel comprising the step of changing a projection variable related to said label, said change not being applied to a larger display area of which the label is a part.

7. A method according to claim 6 wherein said variable is a label color.

8. A method according to claim 6 wherein said variable is light source power.

9. A method according to claim 6 wherein said variable is the dwell time of projection of label information.
