Bearing-based selection in mobile spatial interaction

EgoViz - A Mobile Based Spatial Interaction System

This paper describes research carried out in the area of mobile spatial interaction and the development of a mobile (i.e. on-device) version of a simulated web-based 2D directional query processor. The TellMe application integrates location (from GPS, GSM, WiFi) and orientation (from digital compass/tilt sensors) sensing technologies into an enhanced spatial query processing module capable of e...

Understanding Mobile Spatial Interaction in Urban Enviroments

In order to act in urban environments an individual access various types of knowledge, such as memories, spatial strategies and also information from the environment in order to develop plans and make decisions. This paper will investigate the nature of spatial knowledge acquisition by comparing performance in a task where the subjects learnt the environment using spatial assistance; either fro...

Context-based Spatial Description Selection 1 Running head: CONTEXT-BASED SPATIAL DESCRIPTION SELECTION Context-based Spatial Description Selection

This paper describes how spatial description selection can be tied to discourse and spatial context to improve text coherence in a natural language generation domain. The paper argues that, given coherence relations and discourse goals, the selection of spatial descriptions which reflect the hearer’s spatial expectations and echo the intended coherence relation can improve text coherence and th...

Spatial Design for Knot Selection in Knot-Based Low-Rank Models

‎Analysis of large geostatistical data sets‎, ‎usually‎, ‎entail the expensive matrix computations‎. ‎This problem creates challenges in implementing statistical inferences of traditional Bayesian models‎. ‎In addition,researchers often face with multiple spatial data sets with complex spatial dependence structures that their analysis is difficult‎. ‎This is a problem for MCMC sampling algorith...
