Granularity in Route Directions Generated by Systems and Humans
نویسندگان
چکیده
We address spatial granularity in route directions in relation to information needs in a case study that provides a situation involving different modalities of travel (i.e., walking and travel by public transport). Results reveal that the two sets of route directions investigated (human and web-based) provide the most crucial route elements in hierarchically structured ways that reflect the salient structure imposed by multi-modal traveling. However, human route directions account for the asymmetric information needs assumed for the given scenario in a more flexible and coherent way.

Considerations for Efficient Communication of Route Directions
We can observe that people familiar with an environment give route directions of varying granularity to other locals. Such route directions are typically shorter than the turn based directions of current navigation services, and contain only references of high relevance to the wayfinder. Studying these route directions of varying granularity reveals that they are intended to be memorized, a pro...
متن کاملVariable Granularity in Route Directions
This paper addresses changes of spatial granularity in route directions in relation to information needs in multi-modal traveling. We outline a model of variability in granularity and apply this model to empirical data. Results reveal that human as well as computer generated route directions provide onedimensional route elements in hierarchically structured ways that reflect the salient structu...
متن کاملAutomatic Extraction of Destinations, Origins and Route Parts from Human Generated Route Directions
Researchers from the cognitive and spatial sciences are studying text descriptions of movement patterns in order to examine how humans communicate and understand spatial information. In particular, route directions offer a rich source of information on how cognitive systems conceptualize movement patterns by segmenting them into meaningful parts. Route directions are composed using a plethora o...
متن کاملContext-specific Route Directions
Today’s wayfinding assistance systems provide route directions that are significantly different to those generated by humans, resulting in a gap between what users expect and what the system delivers. This dissertation contributes to closing this gap by presenting a process that adapts instructions to environmental characteristics and a route’s properties, thereby implementing principles of hum...
متن کاملPresenting spatial information: Granularity, relevance, and integration
In recent years the availability of automatically generated spatial information of various kinds has developed dramatically. Route descriptions of diverse kinds can be obtained from many different sources and across different modalities, and maps and geographic information can be accessed in multifarious ways. Although this is situation improves the information availability and accessibility— t...
