Navigation system and control program

Abstract: PROBLEM TO BE SOLVED: To provide a navigation system and a control program that can navigate a user to his/her destination by controlling the reproduction of music. SOLUTION: This navigation system 100 for walkers is provided with a position detecting device 110 for detecting the present position of the navigation system 100, a controlling device 105 for executing a navigation processing, a music control outputting device 160 for reproducing a music data selected by a user until he/she arrives at his/her destination, and a headphone 170 for outputting the reproduced music. The controlling device 105 determines which indication of forward, rightward, leftward, and backward is appropriate, on the basis of the data of present position supplied from the position detecting device 105, and controls the volume balance of music outputted form the right and left speakers of the headphone 170 according to the result, so that the user can be navigated to his/her destination.

Towards Understanding How Speech Output Affects Navigation System Credibility

Abstract: Navigation systems are widely used yet little is understood about how aspects of the interaction impact our assessment of these systems. Our work focuses on the speech output, exploring how accent and system errors affect our credibility judgements. Findings from a small-scale pilot study show that destination errors significantly affect user trust and competence assessments of a navigation system. People also rate navigation systems using speech output with a similar accent to their own as more trustworthy than a system using a different accent, irrespective of destination errors made. Future work looks to increase the scale of the study and add further conditions to explore the role of user nationality, accent and the geographical location being navigated on system credibility.

Method of providing intersection assistance and related portable electronic device

Abstract: A method of providing intersection assistance with a portable electronic device to remind a user of traffic rules when the user approaches traffic intersections includes receiving an input from the user indicating a destination location for generating navigation instructions to the destination location, determining a current location of the portable electronic device according to received position signals, providing navigation instructions to the destination location according to the current location of the portable electronic device, and reminding the user of traffic rules related to intersections for a geographical location in which the portable electronic device is currently located when the portable electronic device detects that the portable electronic device is approaching an intersection, where reminding the user of traffic rules related to intersections comprises indicating a side of a second road the user should turn onto when making a turn from a first road onto the second road.

Empirical comparison of the use of distance versus landmark information within the human-machine interface for vehicle navigation systems

Abstract: Current in vehicle navigation systems place an emphasis on the use of distances within their turn-by-turn directions. Previous work has shown the potential for landmarks, particularly in relation to subjective aspects of system usability e.g. confidence in navigation. To test the objective benefits of landmarks versus distances, road based trials were conducted in which 28 participants drove unfamiliar routes within an urban area using a simulated navigation system that emphasizes either landmarks or distances for the purposes of locating maneuvers. When using the landmark system, relatively few glances were made towards the navigation display and workload was perceived to be lower, in comparison with the figures attained for the distance system. Furthermore, the duration of glances towards the landmark display was low. Nevertheless, the participants made some navigational errors when using landmarks. The results are discussed in relation to the design of future landmark-oriented navigation systems.

Navigation module of Blavigator prototype

Abstract: People with vision disabilities deal with serious limitations while moving around. Common navigation systems do not fully address the needs of blind people, which can only be attended with an adapted product. Blavigator is a navigation system for the blind, currently being developed at the University of Tras-os-Montes e Alto Douro. Blavigator proposes a solution to enhance mobility, finding routes and providing contextual information about points of interest in user's surroundings, guiding him to a desired destination. In this paper is presented the navigation module of Blavigator that ensures a continuous feed of information with sufficient detail allowing the blind user to reach the desired destination successfully. A pilot test with 5 blindfolded persons was conducted to test the navigation module feasibility and do some performance analysis. The results are promising and provide evidence that the navigation module helps blind people to successfully reach the desired destination.
