This paper proposes a novel concept to assist visually impaired individuals in recognizing three-dimensional objects in everyday environments. This concept is realized as a portable system that consists of a white cane, a Microsoft Kinect sensor, a numeric keypad, a tactile feedback device, and other components. By the use of the Kinect sensor, the system searches for an object that a visually impaired...
This paper proposes a method of recognizing elevators in corridor scenes by using our Kinect cane system for the visually impaired. The proposed method recognizes elevator doors by applying the RANSAC algorithm to depth data obtained by a Kinect sensor. The method is applied to actual corridor scenes that include various types of elevator. The experimental results indicate that the system is promising...
This paper proposes a novel concept for helping the visually impaired know what kind of object there is in an environment. This concept is implemented as a cane system that selects a target object based on a user's demand, recognizes the object from depth data obtained by a Microsoft Kinect sensor, and returns the recognition results via a tactile device. The proposed system is evaluated through a...
This paper proposes the Kinect cane system that can detect obstacles in indoor environments and inform a visually impaired user about them. A user study where two blindfolded subjects actually use the system to reach a destination in an experimental environment is carried out to evaluate the effectiveness of the proposed system. The experimental results indicate that the system is promising as a means...
This paper proposes a novel assistive system for the visually impaired. The system is composed of a Microsoft Kinect sensor, keypad-type controller, tactile device, laptop computer and so on. The system can recognize three-dimensional objects from depth data generated by the Kinect sensor, and inform visually impaired users not only about the existence of objects, but also about their classes such...
