TL;DR: This article investigates the efficacy of hands-free, speech-based navigation in the context of dictation-oriented activities, and identifies changes that will reduce failure rates and lessen the consequences of some remaining failures.
Abstract: Speech recognition technology continues to improve, but users still experience significant difficulty using the software to create and edit documents. In fact, a recent study confirmed that users spent 66% of their time on correction activities and only 33% on dictation. Of particular interest is the fact that one third of the users' time was spent simply navigating from one location to another. In this article, we investigate the efficacy of hands-free, speech-based navigation in the context of dictation-oriented activities. We provide detailed data regarding failure rates, reasons for failures, and the consequences of these failures. Our results confirm that direction-oriented navigation (e.g., Move up two lines) is less effective than target-oriented navigation (e.g. Select target). We identify the three most common reasons behind the failure of speech-based navigation commands: recognition errors, issuing of invalid commands, and pausing in the middle of issuing a command. We also document the consequences of failed speech-based navigation commands. As a result of this analysis, we identify changes that will reduce failure rates and lessen the consequences of some remaining failures. We also propose a more substantial set of changes to simplify direction-based navigation and enhance the target-based navigation. The efficacy of this final set of recommendations must be evaluated through future empirical studies.

TL;DR: In this paper, a navigation device which is operative to navigate a user along a selected route, utilizing displays of relevant map sections and the selected route is presented by a control unit in accordance with changes in user's present position.
Abstract: A navigation device which is operative to navigate a user along a selected route, utilizing displays of relevant map sections and the selected route. The relevant map section is updated by a control unit in accordance with changes in user's present position. The control unit includes a picture processor which controls the display unit to show in a distinctive manner within a relevant map section the route segment already travelled and the segment yet to be travelled. The resulting display can therefore be very quickly interpreted by the user.

TL;DR: The concept of a tactile compass is presented, which encodes the direction of a location "as the crow flies" in rhythmic patterns and its distance in the pause between two patterns and together with the map it improved the participants' confidence in the navigation system.
Abstract: This paper reports from the first systematic investigation on how to guide people to a destination using the haptic feedback of a mobile phone and its experimental evaluation. The aim was to find a navigation aid that works hands-free, reduces the users' distraction, and can be realised with widely available handheld devices. To explore the design space we developed and tested different prototypes. Drawing on the results of these tests we present the concept of a tactile compass, which encodes the direction of a location "as the crow flies" in rhythmic patterns and its distance in the pause between two patterns. This paper also reports from the first experimental comparison of such tactile displays with visual navigation systems. The tactile compass was used to continuously display the location of a destination from the user's perspective (e.g. ahead, close). In a field experiment including the tactile compass and an interactive map three conditions were investigated: tactile only, visual only, and combined. The results provide evidence that cueing spatial locations in vibration patterns can form an effective and efficient navigation aid. Between the conditions, no significant differences in the navigation performance were found. The tactile compass used alone could significantly reduce the amount of distractive interaction and together with the map it improved the participants' confidence in the navigation system.

TL;DR: In this article, the influence of different navigation designs (vertical versus dynamic menus) and task complexity (simple versus complex navigation tasks) on user performance, navigation strategy, and subjective preference was compared.

TL;DR: In this article, a user profile (60, 62, 64, 66, 68, 68) based navigation system is presented. But the system is limited to the use of location centric information.
Abstract: A user profile (60, 62, 64, 66, 68) based navigation system. The navigation system stores location centric information in a database (33) associated with a user profile (60, 62, 64, 66, 68). Information from the database (33) is provided to users (31, 37, 41) based on a selected user profile, which modifies the types of data provided to a user at a geographic location. Data in the database (33) is loaded into the database based on user supplied information and an indication of user geographic location.
