Devices and methods for assisting and guiding a person with visual and/or hearing impairment. In various embodiments there is a computer-guided, motorized walking stick. Preferably, at least one wheel at the distal end of the stick, and in contact with the ground, can be steered or pivoted over a range of angles, and thus establish a desired direction. In yet other embodiments there are one or more powered wheels that further drive the walking stick in the desired direction. Various algorithms are disclosed for providing instructions to the computer controller by way of various input devices. Still further embodiments include various types of sensors that provide data to the computer with regards to objects proximate to the walking stick.
