Abstract

A mobile platform includes one or more haptic feedback elements that are positioned in regions of the mobile platform that are proximate to a facial region of a user while the user holds the mobile platform to an ear. By way of example, the haptic feedback elements may be electric force elements that overlay a display or vibrating or thermal elements. The mobile platform is capable of determining a current location and receiving a desired location, which may be, e.g., a location provided by the user, a location with superior signal strength or of another mobile platform. The mobile platform determines directions from the present location to the current location and translates the direction in to control signals. Haptic signals are produced to the facial region of the user by the haptic feedback elements in response to the control signals, thereby providing the directions to the user.
