In this article, a new design of a wearable navigation support system for blind and visually impaired people (BVIP) is proposed. The proposed navigation system relies primarily on sensors, real-time processing boards, a fuzzy logic-based decision support system, and a user interface. It uses sensor data as inputs and provides the desired safety orientation to the BVIP. The user is informed about the decision based on a mixed voice–haptic interface. The navigation aid system contains two wearable obstacle detection systems managed by an embedded controller. The control system adopts the Robot Operating System (ROS) architecture supported by the Beagle Bone Black master board that meets the real-time constraints. The data acquisition and obstacle avoidance are carried out by several nodes managed by the ROS to finally deliver a mixed haptic–voice message for guidance of the BVIP. A fuzzy logic-based decision support system was implemented to help BVIP to choose a safe direction. The system has been applied to blindfolded persons and visually impaired persons. Both types of users found the system promising and pointed out its potential to become a good navigation aid in the future.

This article reports on research into the navigational practices of blind and visually impaired people in urban environments. The members of this community encounter many types of obstacles, but this article focuses on ‘unpredictable inanimate moveable objects’. The analyses are based on recorded video material from ‘naturally occurring’ walks in a Danish urban area and are informed by ethnomethodology, with a focus on how blind or visually impaired people navigate and deal with trouble sources. This research unpacks the detailed features of navigation and obstacle-detection in the urban environment and demonstrates the value of using ethnomethodology to analyze the skilled character of everyday navigation in spaces in which the walker-with-cane is a kind of assemblage in harmony or at odds with other surfaces and objects. The findings have implications for space design and technology developments which can assist blind people with obstacle detection. The article uses empirical cases to discuss an ocular-centric bias and suggests the need for a more granular understanding of physical objects and tactile experiences in future developments of a sociology of space.

This paper describes the development of decision support system application to assist students who want to enter college so that no one choose the majors incorrectly. This application uses fuzzy logic method because fuzzy logic is very flexible in data which are vague and can be represented as a linguistic variable. The purpose of this application is to assist students to choose available majors at University Multimedia Nusantara which are appropriate with his/her capabilities. This application accepts five kinds of input values i.e. Mathematics, Indonesian, English, Physics, and TIK. Received input will be processed by the calculation of the system for decision-making and the application will generate output that shows how great a match for each majors. With this application, prospective students can find out where the majors that match his/her capabilities. This application has ninety nine percentage of match result accuracy. Index Terms—fuzzy logic, decision support system, UMN, selection of major
