Wearable object detection system for the blind

摘要: The blind's capacities to navigate in a particular place and organize their daily activities are of vital importance for health well-being. Organizing any kind simple activity can be especially difficult; it is not easy the blind distinguish different items, such as packaged foods drug containers just by touching with hands. RFID, or radio frequency identification, technology that provide support improving organization orientation during daylight activities. RFID uses waves deliver data from tag, which stores information, reader, elaborate information making decisions. This very useful many contexts scanning passports, shipments automatic highway toll collecting. As stands out its inherent technical nature basic system, may involve additional improvements numerous applications field care. In this paper, device designed searching some objects presented; particular, has been develop medicines cabinet at home. able pieces about distance simplify search; besides identifying medicines, user an acoustic signal order find easily desired product soon possible. It noteworthy fact gives items defined object, how near far is. application obtained using RSSI (Received Strength Signal Indicator) value, measuring power received tag.
