Social vehicle navigation: integrating shared driving experience into vehicle navigation

Abstract: In this paper, we propose a Social Vehicle Navigation system that integrates driver-provided information into a vehicle navigation system in order to calculate personalized routing. Our approach allows drivers registered into certain vehicle social network groups to share driving experiences with other drivers using voice tweets. These tweets are automatically aggregated into tweet digests for each social group based on location and destination. While listening to the tweet digests, a driver can instruct the social navigator to avoid or choose certain road segments in order to calculate a personalized route. We present our initial design along with a simple prototype implemented for the Android platform.

Facilitating Effective User Navigation through Website Structure Improvement

Abstract: Designing well-structured websites to facilitate effective user navigation has long been a challenge A primary reason is that the web developers' understanding of how a website should be structured can be considerably different from that of the users While various methods have been proposed to relink webpages to improve navigability using user navigation data, the completely reorganized new structure can be highly unpredictable, and the cost of disorienting users after the changes remains unanalyzed This paper addresses how to improve a website without introducing substantial changes Specifically, we propose a mathematical programming model to improve the user navigation on a website while minimizing alterations to its current structure Results from extensive tests conducted on a publicly available real data set indicate that our model not only significantly improves the user navigation with very few changes, but also can be effectively solved We have also tested the model on large synthetic data sets to demonstrate that it scales up very well In addition, we define two evaluation metrics and use them to assess the performance of the improved website using the real data set Evaluation results confirm that the user navigation on the improved structure is indeed greatly enhanced More interestingly, we find that heavily disoriented users are more likely to benefit from the improved structure than the less disoriented users

Navigation application with several navigation modes

Abstract: A method for providing navigation instructions on a device is described. As the device traverses a navigated route according to a first mode of transportation, the method displays a first turn-by-turn navigation presentation defined for the first mode. Based on data gathered by the device, the method determines that the device is navigating the route according to a second mode of transportation. The method automatically displays a second, different turn-by-turn navigation presentation defined for the second mode.

System and method for data-driven web page navigation control

Abstract: A system and method for web application navigation control includes updating navigation data models used in navigation constraints with received data from an end-user or system. Without needing a centralized application-specific controller, from a collection of extensible navigation rules associated with each page of a plurality of pages, the extensible navigation rules are automatically selected which depend on changed data values and need re-evaluation. The navigation constraints associated only with the pages potentially changing their ready state to execute from among the plurality of pages in an entire application are evaluated to determine which pages are ready to run based on updated data from the navigation data models. A preferred page to be actually navigated to next is selected from among a set of all available and ready pages by execution of a set of second and separate navigation constraints using results of the navigation constraints of the evaluating step.

Semantic Indoor Navigation with a Blind-User Oriented Augmented Reality

Abstract: The aim of this paper is to design an inexpensive conceivable wearable navigation system that can aid in the navigation of a visually impaired user. A novel approach of utilizing the floor plan map posted on the buildings is used to acquire a semantic plan. The extracted landmarks such as room numbers, doors, etc act as a parameter to infer the way points to each room. This provides a mental mapping of the environment to design a navigation framework for future use. A human motion model is used to predict a path based on how real humans ambulate towards a goal by avoiding obstacles. We demonstrate the possibilities of augmented reality (AR) as a blind user interface to perceive the physical constraints of the real world using haptic and voice augmentation. The haptic belt vibrates to direct the user towards the travel destination based on the metric localization at each step. Moreover, travel route is presented using voice guidance, which is achieved by accurate estimation of the user's location and confirmed by extracting the landmarks, based on landmark localization. The results show that it is feasible to assist a blind user to travel independently by providing the constraints required for safe navigation with user oriented augmented reality.

A VANET-Based A* Route Planning Algorithm for Travelling Time- and Energy-Efficient GPS Navigation App:

Abstract: Most current navigation devices or apps, based on the global positioning system (GPS), only adopt static information for route planning. Although some are equipped with an RDS-TMC receiver to receive real-time traffic events, many of these real-time traffic events are irrelevant to the vehicle. This paper offers three major contributions. First, a vehicular-ad-hoc-network- (VANET-) based () route planning algorithm is proposed to calculate the route with the shortest travelling time or the lowest fuel consumption, depending on two real-time traffic information sources, which have not been used in traditional GPS navigation applications. The first traffic information source is the recorded traffic information of the road segment that the vehicle has passed through. It is further exchanged between vehicles through an IEEE 802.11p wireless link. The second traffic information is provided by Google Maps. A GPS navigation app is then implemented on the Android platform to realize . Finally, simulations for six route planning algorithms are executed by VANET simulator The ONE, in one congested and one noncongested time period, respectively. In summary, achieves significant reductions in both the average travelling time and fuel consumption of the planned route, as compared to traditional route planning algorithms.

Indoor inertial waypoint navigation for the blind

Abstract: Indoor navigation technology is needed to support seamless mobility for the visually impaired. This paper describes the construction and evaluation of an inertial dead reckoning navigation system that provides real-time auditory guidance along mapped routes. Inertial dead reckoning is a navigation technique coupling step counting together with heading estimation to compute changes in position at each step. The research described here outlines the development and evaluation of a novel navigation system that utilizes information from the mapped route to limit the problematic error accumulation inherent in traditional dead reckoning approaches. The prototype system consists of a wireless inertial sensor unit, placed at the users' hip, which streams readings to a smartphone processing a navigation algorithm. Pilot human trials were conducted assessing system efficacy by studying route-following performance with blind and sighted subjects using the navigation system with real-time guidance, versus offline verbal directions.

We conclude by recommending further work in presenting interior navigation instructions using AR.

Visual semantic parameterization - To enhance blind user perception for indoor navigation

Abstract: This paper presents a novel approach of utilizing the floor plan maps posted on the buildings to infer a semantic plan that aids in the navigation of a visually impaired person. The extracted landmarks such as room numbers, doors, etc act as a parameter to infer the way points to each room. This provides a mental mapping of the environment to design a navigation framework for future use. A human motion model is used to predict a path based on how real humans ambulate towards a goal by avoiding obstacles. Travel route is presented in terms of blind understandable units, which is achieved by accurate estimation of the user's location and confirmed by extracting the landmarks posted on the doors. The results show that it is feasible to make a blind user to travel independently by providing the constraints required for safe navigation.

Sensor Network Navigation without Locations

Abstract: We propose a pervasive usage of the sensor network infrastructure as a cyber-physical system for navigating internal users in locations of potential danger. Our proposed application differs from previous work in that they typically treat the sensor network as a media of data acquisition while in our navigation application, in-situ interactions between users and sensors become ubiquitous. In addition, human safety and time factors are critical to the success of our objective. Without any preknowledge of user and sensor locations, the design of an effective and efficient navigation protocol faces nontrivial challenges. We propose to embed a road map system in the sensor network without location information so as to provide users navigating routes with guaranteed safety. We accordingly design efficient road map updating mechanisms to rebuild the road map in the event of changes in dangerous areas. In this navigation system, each user only issues local queries to obtain their navigation route. The system is highly scalable for supporting multiple users simultaneously. We implement a prototype system with 36 TelosB motes to validate the effectiveness of this design. We further conduct comprehensive and large-scale simulations to examine the efficiency and scalability of the proposed approach under various environmental dynamics.

A low cost outdoor assistive navigation system for blind people

Abstract: With over 39 million visually impaired people worldwide, the need for an assistive device that allows the blind user navigate freely is crucial. We have developed an off-line navigation device that uses 3-D sounds to provide navigation instructions to the user. Our device relays directional information to the user through special Audio Bone headphones, which use bone conduction technology. Sounds are recorded and can therefore be selected by the blind user. Navigation processing is handled by a Raspberry Pi. We are using a magnetic compass and gyroscope to calculate the direction that the user is facing. Route queries of the destination address are geocoded using the Geo-Coder-US module and passed to the MoNav module to generate a pedestrian route. Additional capabilities of the device include speech recognition and voice prompts for obtaining the user's desired destination address. The user can input the address b y speaking into a microphone. The entire system is mounted to a pack that sits on the user's waist. It is very light and portable and it does not impede any of the user's senses while it is being used.

Probabilistic approach to recognize local navigation plans by fusing past driving information with a personalized user model

Abstract: Navigating an electrical wheelchair can be very challenging due to its large size and limited maneuverability. Additionally, target users often suffer from cognitive or physical disabilities, which interfere with safe navigation. Therefore, a robotic wheelchair that helps to drive can prove invaluable. Such a wheelchair shares the control with its human operator. Typically, robots excel in fine-motion control whereas users want to remain in charge. Hence, the robot should focus its help locally and let the user decide about global behavior. Further, an effective robot should understand the navigation plans of its user. It needs to consider the user's abilities to avoid frustrating the user with wrong assistance. In order to address these requirements, we propose a probabilistic framework to recognize local navigation plans in a user-specific way. The framework infers navigation plans online and provides a method to calibrate all model parameters from real driving data. It fuses past local information with a user-specific model to reason about how and where the user intends to navigate. We illustrate the validity of our approach by recognizing the local navigation plans of a spastic user driving in a daily environment.

Mirrored interface navigation of multiple user interfaces

Abstract: Mirrored interface navigation is disclosed between two or more mobile devices with similar capabilities. When a connection is established between the mobile devices, interface navigation actions detected on a first of the connected devices are transmitted to the other devices. The other devices receive and execute those interface navigation actions to perform parallel interface navigation with the first mobile device. For example, two smart phones are connected for shared interface navigation, interface navigation actions performed on the first smart phone are translated to the second smart phone to perform mirrored parallel interface navigation. The mirrored parallel interface navigation may occur regardless of device type or specific application, such that interface navigation actions on an Apple, Inc., IPHONE® may result in parallel interface navigation on a Google ANDROID®-based phone to similar application types.

Dynamic Presentation of Navigation Instructions

Abstract: In some implementations, a mobile device can be configured to provide navigation instructions to a user of the mobile device. The navigation instructions can be graphical, textual or audio instructions. The presentation of the navigation instructions can be dynamically adjusted based the importance of individual instructions and/or environmental conditions. For example, each navigation instruction can be associated with an importance value indicating how important the instruction is. The volume of important audio instructions can be adjusted (e.g., increased) to compensate for ambient noise so that a user will be more likely to hear the navigation instruction. The timing and/or repetition of the presentation of important instructions can be adjusted based on weather conditions, traffic conditions, or road conditions and/or road features so that a user will be less likely to miss an important navigation instruction.
