“…Given this, GPS systems are good candidates for investigating the design issues arising in minimal attention user interfaces. As noted above, GPS navigation systems for the visually impaired have been studied PAGE 4 by several authors [6,7,8,9,10]. By contrast, in this paper, we consider a minimal attention user interface for the sighted person who is simultaneously involved in other demanding tasks.…”

“…Since the deployment of satellite-based navigation networks (the American Global Positioning System (GPS) and the Russian GLONASS networks), and with recent advances in speech technology, the majority of navigation aids have been based on these two technologies. Such navigation aids include the Personal Guidance System [6,7], the Personal Navigation System [8], the Mobility of Blind and Elderly People Interacting with Computers system (MOBIC) [9] and a navigation system for the blind that uses a GPS and a mobile telephone connection [10]. These devices have the dual function of supporting navigation whilst also informing the user about relevant landmarks of interest to them.…”

In this paper we describe a prototype audio user interface for a Global Positioning System (GPS) that is designed to allow mobile computer users to carry out a location task while their eyes, hands or attention are otherwise engaged. Audio user interfaces for GPS have typically been designed to meet the needs of visually impaired users, and generally (though not exclusively) employ speechaudio. In contrast, our prototype system uses a simple form of non-speech, spatial audio. This paper analyses various candidate audio mappings of location and distance information. A variety of tasks, design considerations, technological opportunities and design trade-offs are considered.The findings from pilot evaluation experiments are reported. Finally, opportunities for improvements to the system and for future empirical testing are explored.

Abstract-This paper presents an indoor localization system for the visually impaired. The basis of our system is an Extended Kalman Filter (EKF) for six degree-of-freedom (d.o.f.) position and orientation (pose) estimation. The sensing platform consists of an Inertial Measurement Unit (IMU) and a 2D laser scanner. The IMU measurements are integrated to obtain pose estimates which are subsequently corrected using line-toplane correspondences between linear segments in the laserscan data and known 3D structural planes of the building. Furthermore, we utilize Lie derivatives to show that the system is observable when at least three planes are detected by the laser scanner. Experimental results are presented that demonstrate the reliability of the proposed method for accurate and realtime indoor localization.

This paper describes the prototype version of a mobile application supporting independent movement of the blind. Its objective is to improve the quality of life of visually impaired people, providing them with navigational assistance in urban areas. The authors present the most important modules of the application. The module for precise positioning using DGPS data from the ASG-EUPOS network as well as enhancements of positioning in urban areas, based on the fusion with other types of data sources, are presented. The devices, tools and software for the acquisition and maintenance of dedicated spatial data are also described. The module responsible for navigation with a focus on an algorithms' quality and complexity, as well as the user interface dedicated for the blind are discussed. The system's main advantages over existing solutions are emphasized, current results are described, and plans for future work briefly outlined.
