Abstract
A visually handicapped person guidance and support apparatus comprises a resonance tag, antenna and portable scanner. The resonance tag has an inductance element defined by a pair of conductive foil and a capacitance element coupled in distributed capacity to the conductive foil through a dielectric thin film. The visually handicapped person scans the resonance tag with a stick containing the antenna coupled to the portable scanner. The antenna transmits electric waves having the frequency of 5 to 60 MHz and predetermined resonance electric waves are reflected from the resonance tag. The received resonance waves are collated with the memory data by the scanner 3 and converted to voice message for output from a speaker. If a plurality of resonance tags, each of which has a different resonance frequency, are used, a plurality of information such as 'go', 'stop', 'turn to right', 'turn to left' and the like are obtained.
