Recently there has been an interest in spatially-aware systems for pedestrian routing and city exploration, due to the proliferation of smartphones with GPS receivers among the general public. Since GPS readings are noisy, giving good and well-timed route instructions to pedestrians is a challenging problem. This paper describes a spoken dialogue prototype(More)
We demonstrate a spoken dialogue-based information system for pedestrians. The system is novel in combining geographic information system (GIS) modules such as a visibility engine with a question-answering (QA) system, integrated within a dialogue system architecture. Users of the demonstration system can use a web-based version (simulating pedestrian(More)
In this paper, we describe our contribution to the Spoken Dialog Challenge. We set up a user simulation using the large Let's Go corpus as resource to build our models. Automatic calls were made to all four dialog systems in the SDC, bus information systems that cover the schedule of Pittsburgh, PA. We discuss in detail the architecture and required setup(More)
1. Overview This demonstration highlights some features of a dialogue system for pedestrian routing (Boye et al. 2012) that uses natural-language routing instructions to help pedestrians navigate and explore the city in real-time. The instructions are given as the user is moving: When the user reaches a node p i in the planned route, he is informed how to(More)
An automatic mechanism that gives verbal navigation instructions to pedestrians in situ needs to take into account a number of factors. Besides giving the instruction at the right time and place, the information needs to be as unambiguous as possible for the user to both choose the correct path and be confident in doing so. Humans make extensive use of(More)
We present a study in which we seek to interpret spatial references that are part of in-situ route descriptions. Our aim is to resolve these references to actual entities and places in the city using a crowdsourced geographic database (Open-StreetMap). We discuss the problems related to this task, and present a possible automatic reference resolution method(More)
Finding the way in known and unknown city environments is a task that all pedestrians carry out regularly. Current technology allows the use of smart devices as aids that can give automatic verbal route directions on the basis of the pedestrian's current position. Many such systems only give route directions, but are unable to interact with the user to(More)
