Abstract: A safety device for a walker includes a distance measuring sensor for determining whether a user is at too far or too close distances relative to the front side of the walker. The sensor provides data to a CPU processor indicative of such events. The processor includes logic which analyzes such data and provides audial, visual and/or tactile stimuli to the user warning the user that he/she is at undesirable distances relative to the walker. The process logic can be modified so as to vary the type and/or frequency of warnings given to the user.
