Personal guidance apparatus for directing a visually impaired or blind user from a first location to a predefined destination, the apparatus comprising an input unit operable to receive first location data and input destination data; a controller in communication with the input unit and operable to receive first location data and input destination data from the input unit and generate output direction data; and an output unit provided with an array of tactile zones 78a, 78b, 78c, the output unit operable to receive output direction data from the controller and generate a tactually-detectable output pattern at the array to communicate directional information to the user. The tactile zones can produce vibratory signals which can be pulsed. The guidance unit also allows the user to alter the output signals, such as changing the intensity of the stimulation, to suit their individual needs. The tactile elements of the device could be attached to the handle of a walking stick or the handle of a wheelchair.
