Touch Screen Remote

universal remote is a remote control that can be programmed to operate various brands of one or more types of consumer electronics devices. Low-end universal remotes can only control a set number of devices determined by their manufacturer, while mid- and high-end universal remotes allow the user to program in new control codes to the remote. Many remotes sold with various electronic devices include universal remote capabilities for other types of devices, which allow the remote to control other devices beyond the device it came with. For example, a VCR remote may be programmed to operate various brands of televisions.

These remotes feature an LCD screen that can be either monochrome or full color. The "buttons" are actually images on the screen, which, when touched, will send IR signals to controlled devices. Some models have multiple screens that are accessed through virtual buttons on the touch-screen and other models have a combination of the touch-screen and physical buttons.

Some models of the touch-screen remotes are programmed using a graphical interface program on a PC, which allows the user to customize the screens, backgrounds, buttons and even the "actions" the buttons perform. The "project" that is created is then downloaded into the remote through a USB cable or, in the most recent models, wirelessly by Bluetooth or Wi-Fi.

The newest touch-screen remotes, such as the Logitech 900 and 1100, include an RF transmitter to allow signals to reach locations much farther than the usual range of IR (approximately 6 meters). RF also does not require line of sight.
