Assisting the blind to read or recognize signs in daily life is important in modern advanced communities. I constructed a device which enables the blind to read or recognize destinations appearing on a bus: all components were attached to a walking stick. A camera captured an image of the bus label: to recognize destinations, the letters on the image were detected, classified and compared using the EMGU library, Tesseract OCR and the Levenshtein distance computation. The device was tested at different distances and sizes of the bus labels. The test results showed that the destinations were read correctly at the acceptable distance. Thus, this low cost device is useful and feasible for assisting the blind.
