People born with visual impairments encounter many barriers that do not affect those born with full visual capabilities. Simply finding objects in the home can be problematic. Ideally, the objects would be set in exactly the same place each time so they can be easily found again. However, if the object has been misplaced or moved to another location, most visually impaired people must depend on help from someone else who can see clearly. Our study successfully developed a tool for helping visually impaired people find objects at home, even when the location of such objects changes. Without help from anyone else, the visually impaired can use the Voice-based Object Finder (VOF), our voice guiding system, to find objects whose location varies. Visually impaired people have a more heightened sensitivity to sound than do their visually unimpaired counterparts. However, most tools are targeted toward sighted people and do not consider the use of sound which is more useful to the visually impaired. Our VOF adopted UHF RFID technology to create a sound-based directional device. We invited the chairman of the Light & Salt Association (an organization which focuses on facilitation for the visually impaired) to participate in a practical simulation. The results of the test confirmed that the proposed functions of the VOF did, indeed, fulfill the requirements of a tool to help the visually impaired locate objects. The VOF recently received its patent, and since the current patent database shows no similar convenience tool for the visually impaired, a fully-developed VOF will have a ready market. |
