ABSTRACT:
A trackpad or other input/output device is detachable from a computer and adapted with a remote communication functionality using radio frequency (RF) or infrared (IR) technologies, thereby facilitating the performance of slide presentations and other graphic displays. A remote presentation capability allows a computer user to conveniently address a group from a position at a suitable location, such as a podium, that is removed from the computer system. A remote interface includes a trackpad or other input/output device and activation buttons. The input/output device is housed in a small removable enclosure which is adapted for docking into an aperture in the computer. The input/output device is rechargeable with a charger installed into the computer so that the input/output device is recharged during docking with the computer. A portable computer includes a removable input/output (I/O) device that functions as a conventional computer interface when docked to the portable computer and functions as a remote control for controlling operations of the portable computer when the I/O device is removed from the portable computer. The removable I/O device includes one or more activation buttons for usage in controlling operations such as the display operations of an audio-visual presentation. When the I/O device is removed from the portable computer, the I/O device communicates with the portable computer using a remote communication technique such as radio frequency (RF) or infrared (IR) remote communication techniques. The removable I/O device include rechargeable batteries that power the I/O device while the device is used remotely. The rechargeable batteries are charged by the portable computer when the I/O device is returned to the portable computer and docked to the portable computer.
