APPARATUS AND OPERATION METHOD FOR VISUALLY IMPAIRED

摘要

A user wearable visual assistance solution is proposed. The apparatus and method of operation for providing specific solution for object detection and object behaviour detection using mm-wave radar approach, where apparatus is attached to the human head, and where the information about environment is presented to the human being by audio signal provision. Advantageously, the apparatus is embedded in spectacles-like shape, being provided to persons with visual impairments. The usage of the integrated mm-wave ISM Band 60 GHz front end, combined with the low cost printed high antenna with specific advantageously proposed radiation diagram, adequate baseband processing, and dedicated audio signal generation, is providing major solution advantage for people, by having light, non bulky, affordable help in daily life. The introduction of the "spectacles- like" support shape, affords the usage, without explicitly optically showing the purpose of the apparatus. Using proposed additional embodiments for apparatus with additional functionalities, and proposed operation method additional features like: pattern recognition, system training on typical obstacles, as well as acoustic guiding and audio navigation are proposed. Proposed invention addresses also features usable for applications for individuals being in darkness, dense fog and fog like environments like smoke. Thus this invention also explicitly addresses specific industrial, security and safety applications.
