Methods and systems for a portable, interactive display device for use with a computer
First Claim
1. A portable display system for use with a computing device, the portable display system usable when it is in contact with a docking station of the computing device and usable when it is not in contact with the docking station, the portable display system comprising:
- a display screen;
a wireless communications receiver;
a tethered communications receiver;
a display rendering module; and
a logic device for determining whether the portable display system is in contact with the docking station, for connecting output from the tethered communications receiver to the display rendering module if the portable display system is in contact with the docking station, and for connecting output from the wireless communications receiver to the display rendering module if the portable display system is not in contact with the docking station, wherein;
the wireless communications receiver receives display signals from the computing device, andthe tethered communications receiver receives display signals from the computing device, the display signals received by the tethered communications receiver being of a higher quality than the display signals received by the wireless communications receiver.

Abstract
A portable, interactive display device is disclosed. The device presents to a user the graphical interface of a host computer. The host is separate from the display device and sits in a fixed location. The invention allows a user to carry with him the user interface capability of the host, limited only by the capabilities of a wireless communications channel to the host. The host provides processing, storage, and access to its own peripheral devices. The display device need only provide the amount of processing necessary to communicate with the host, to run the client side of the hosting software, and to provide security functions. The host provides a docking station that accommodates the display device. When in the docking station, the display device continues to operate but communicates with the host through the docking station rather than through the wireless channel. This allows for a higher quality video connection.

14. A docking station for use with a portable display system and with a computing device, the docking station comprising:
-
a first communications channel to the computing device, first display signals being received at the first communications channel; and a second communications channel to the portable display system, second display signals being received at the second communications channel, wherein the first display signals have higher signal quality than the second display signals. - View Dependent Claims (15, 16, 17, 18)

19. A method for a portable display device with at least two communications receivers to communicate with a computing device, the method comprising:
-
setting a first communications receiver to be a default communications receiver, wherein the first communications receiver receives first display signals from the computing device; evaluating a strength of a communications signal received by the default communications receiver; and if the evaluated strength of the received communications signal is above a predetermined level, then displaying the communications received by the default communications receiver, else displaying the communications received by a second communications receiver, wherein the second communications receiver receives second display signals from the computing device, and the first display signals have higher signal quality than the second display signals. - View Dependent Claims (20)
