A remote control for controlling a home entertainment (HE) device such as an Interactive television having a display screen. The remote control includes a touch pad mapped to the display screen of the HE device as a function of the ratio of the areas of the touch pad and the display screen such that each location of the touch pad corresponds to a respective location of the display screen. The remote controller further includes a controller operable with the touch pad to enable a control function associated with a location of the display screen in response to the corresponding location of the touch pad being touched for controlling the HE device. The display screen may include on-screen keyboards, control panels and menus, an Internet page, an electronic program guide, and the like.
