Refined Route Instructions Using Topological Stages of Closeness
نویسندگان
چکیده
In pedestrian navigation, navigators are free to choose any passable way. Because of this characteristic, accurate route instructions are important when navigating from waypoint to waypoint. In this paper, a theoretical framework is described for dealing with position uncertainty in pedestrian guiding systems. Stages of closeness are defined based on the topological relation between the navigator and a waypoint. These stages of closeness allow for refining route instructions and, therefore, leading to more accurate navigation and increased efficiency of the system.

A Framework for Understanding Verbal Route Instructions
My goal is to understand human verbal route instructions by modeling and implementing the language, knowledge representation, and cognitive processes needed to communicate about spatial routes. To understand human route instructions, I ran a study of how people give and follow route instructions. I modeled the language used in the route instruction texts using standard computational linguistics...
متن کاملRobot Topological Map Generation from Formal Route Instructions
1 Mobile robots and Humanoids need to use spatial information about their surrounding environment in order to effectively plan and execute navigation tasks. This spatial information can be presented in various ways to increase the interaction between the human and the robot. One of the more effective ways is by describing the route verbally which bridges the gap between the forms of spatial kno...
متن کاملA Cognitively Motivated Route-Interface for Mobile Robot Navigation
A more natural interaction between humans and mobile robots can be achieved by bridging the gap between the format of spatial knowledge used by robots and the format of languages used by humans. This enables both sides to communicate by using shared knowledge. Spatial knowledge can be (re)presented in various ways to increase the interaction between humans and mobile robots. One effective way i...
متن کاملNatural Language Generation in the Context of Providing Indoor Route Instructions
Modern robotics applications require robots to be able to communicate with humans seamlessly and effectively. We propose a structured algorithm for natural language generation in the context of indoor route instructions that allows a robot to combine metrical, topological and semantic information about the surrounding environment while generating natural language instructions. Our method learns...
متن کاملVehicle Localization along a Previously Driven Route Using Image Database
In most autonomous driving applications, such as parking and commuting, a vehicle follows a previously taken route, or almost the same route. In this paper, we propose a method to localize a vehicle along a previously driven route using images. The proposed method consists of two stages: offline creation of a database, and online localization. In the offline stage, a database is created from im...
