Abstract

An input and output device having at least one display and a keyboard and, optionally, further input and output elements, such as a microphone, a loudspeaker, a camera, devices for coupling external appliances and/or a pointing device. The device is designed to be portable and can use an air interface for wirelessly accessing the processing capacity or computational power of a fixed data processing apparatus, for example of a PC, and the components thereof.

Claims

1. A portable input and output device for accessing a data processing apparatus, which is separate from the input and output device, via an air interface, the device comprising:

at least one input apparatus for inputting information to be transmitted via the air interface;

at least one output apparatus for outputting information received via the air interface; and

an internal processing part only for inputting and outputting information on the input and output device and for transferring information using the data processing apparatus.

2. A portable input and output device for accessing a data processing apparatus as claimed in claim 1, wherein the data processing apparatus is a personal computer.

3. A portable input and output device for accessing a data processing apparatus as claimed in claim 1, wherein the at least one input apparatus is a keyboard and the at least one output apparatus is a display.

4. A portable input and output device for accessing a data processing apparatus as claimed in claim 1, further comprising:

a microphone and a loud speaker for inputting and outputting at least one of voice, sound and audio signals.

5. A portable input and output device for accessing a data processing apparatus as claimed in claim 1, further comprising:

a camera for inputting image signals.

6. A portable input and output device for accessing a data processing apparatus as claimed in claim 1, further comprising:

a device for inputting and outputting audio and video signals from and to external audio and video appliances.

7. A portable input and output device for accessing a data processing apparatus as claimed in claim 1, further comprising:

a mouse controller.

8. A portable input and output device for accessing a data processing apparatus as claimed in claim 1, wherein the air interface is formed by one of an infrared transmission link, an ultrasound transmission link and a radio-electric transmission link.
