Design and development of navigation system by using RFID technology
In this modern era, independent mobility for blind and partially sighted people is an important objective to achieve. There are many assistive way to help visually impaired people namely, Guide Dog, White Cane as well as the tactile paving which is a very common assistive tool throughout the world, support the visually disable person walk in the correct path from one place to another. Therefore, RFID technology is introduced in this project to support the visual disable people more efficiently in outdoor activities. The system has been developed based on the integration of RFID wireless technology and voice system which assembled on the traditional white cane in order to help the visual impairment to identify the surrounding landmark via verbal notification. The tactile detection by RFID system composed by RFID system integrated on traditional white cane and RFID TAG which installed on the tactile paving where the TAG stored unique information uses to navigate/notify the user once they scan/tap the tactile paving by the designed white cane. The proposed RFID integrated white cane is successfully designed and evaluated the range of RFID tag which can be detected.

Control of intelligent cane robot considering usage of ordinary cane
Intelligent cane is a robot developed for assisting the elderly or handicapped people in walking. As a nursing-care device, the cane robot is designed to assist the elderly or handicapped people not only in indoor environments but also in outdoor environments. Therefore the cane robot is required to be smaller and lighter. In addition, it is preferred that the cane robot is movable in omni-directions so that it can be used in various situations. A concept called “intentional direction (ITD)” was proposed to estimate the user's walking intention by analyzing signals from a 6-axis force/torque sensor fixed to the handle of the aluminum stick. Admittance control method was applied to the motion control of the cane robot. In this paper, a new algorithm based on the usage and purpose of an ordinary cane is proposed. In the proposed algorithm, the cane robot is appropriately stopped to support the elderly more effectively. The effectiveness of the proposed method is verified through the experiments.
