Abstract

A device for inputting data into an information processing apparatus using a communication cable. The device includes a sensing field including signal lines. The sensing field generates one or more signals when an object is proximate thereto. The device further includes at least one processor connected to the signal lines. The processor receives the signals and generates data based on the signals. The device additionally includes a port in communication with the processor for data output. The port is configured to connect to the cable end communicate the data over the cable to the information processing apparatus. The device includes a light source configured to illuminate keyboard symbols corresponding to areas of the sensing field. The device also includes an exterior surface covering the sensing field and obscuring the keyboard symbols from visibility unless the light source is providing illumination.

First claim

The invention claimed is:

1. A device for inputting data into an information processing apparatus on a vehicle using a cable, the device comprising:
a sensing field including a plurality of signal lines, the sensing field generating one or more signals when an object is proximate the sensing field and communicating the signals over the signal lines indicative of location of the object;
a processor connected to the signal lines in which the processor receives the signals from the sensing field and generates data based on the signals received;
a port in communication with the processor which outputs data thereto, the port being configured to connect to the cable and communicate the data received from the processor over the cable to the information processing apparatus;
a light source configured to illuminate keyboard symbols corresponding to areas of the sensing field; and
an exterior surface covering the sensing field and obscuring the keyboard symbols from visibility unless the light source is providing illumination, the exterior surface comprising a fire retardant plastic and forming part of the vehicle.

2. The device of claim 1 , further comprising depressions disposed over the exterior surface to increase friction between the exterior surface and an object in contact therewith in which the depressions have been formed by blasting the surface with particles.

3. The device of claim 1 , further comprising a cylindrical recess defined in the exterior surface for receiving a beverage container therein, the exterior surface being arranged to vibrate to provide haptic feedback when a keystroke has been registered by the device.

4. The device of claim 1 , wherein the light source comprises a light guide and a plurality of LEDs in optical communication with the light guide in which the LEDs emit light to illuminate the light guide and the keyboard symbols through the exterior surface.

5. The device of claim 4 , wherein the port comprises a USB port in which the port receives power from the information processing apparatus when connected thereto via the cable and supplies power therefrom to the LEDs.

6. The device of claim 4 , wherein the port comprises a USB port in which the port receives power from the information processing apparatus via the cable and supplies power therefrom to the LEDs for illumination thereof.

7. The device of claim 4 , wherein the sensing field comprises a capacitive touch panel.
