Dotdotdot / Handheld Scanner


Dotdotdot is designed to help visually impaired persons when they shop offline. There are many advantages of shopping at offline stores. For instance, customers can experience products by touching, smelling and seeing them before they buy. However, most information in the stores are displayed only in a visual means. So for persons who have visual impairment, this has been a barrier for a long time. By utilizing barcodes, Dotdotdot eliminates this barrier and provides more convenient shopping environment for the visually impaired people.
