Methods and systems for a portable, interactive display device for use with a computer

A docking station for use with a portable display system and with a computing device, the portable display system distinct from the computing device, the docking station comprising:

• a first communications channel to the computing device;
• a second, wireless communications channel for transmitting display signals to the portable display system;
• a third, tethered communications channel for transmitting display signals to the portable display system, the display signals transmitted by the tethered communications channel being of a higher quality than the display signals transmitted by the wireless communications channel;
• and
• a logic device for detecting whether the portable display system is in contact with the docking station, the detecting based, at least in part, on a strength of a communications signal received by the tethered communications channel, and for connecting display input from the first communications channel to the second communications channel of the portable display system is in contact with the docking station, and for connecting display input from the first communications channel to the third communications channel if the portable display system is not in contact with the docking station.

A method for a portable display device with a first and a second communications receiver for receiving display signals to communicate with a computing device, the portable display system distinct from the computing device, the method comprising:

• setting the first communications receiver to be a default communications receiver, the display signals received by the first communications receiver being of a higher quality than the display signals received by the second communications receiver;
• 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, the displaying the communications received by the default communications receiver, else displaying the communications received by the second communications receiver.

A computer-readable medium having instructions for performing a method for a portable display device with a first and a second communications receiver for receiving display signals to communicate with a computing device, the portable display system distinct from the computing device, the method comprising:

• setting first communications receiver to be a default communications receiver, the display signals received by the first communications receiver being of a higher quality than the display signals received by the second communications receiver;
• 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, the displaying the communications received by the default communications receiver, else displaying the communications received by the second communications receiver.
