Considering the empowered customer interacting with technology-based self-services, temporal and spatial access can be argued to influence service delivery. However, service management models have not considered the value of the service delivery at various locations and time frames not controlled by the service provider. Consequently, by arguing that time and location are explicit value dimensi...

We investigated learning of spatio-temporal interpolation in depth and its relation to spatio-temporal interpolation in two dimensions by means of a vernier discrimination task. Performance improved with training but improvement did not or only partially transfer between opposite directions of motion in depth. Improvement was also at least partly specific for the eye and for the direction of tw...

This paper presents our work in mapping the design space of techniques for temporal graph visualisation. We identify two independent dimensions upon which the techniques can be classified: graph structural encoding and temporal encoding. Based on these dimensions, we create a matrix into which we organise existing techniques. We identify gaps in this design space which may prove interesting opp...

Visual query systems (VQS) for spatio-temporal databases, which enable formulation of queries involving both spatial and temporal dimensions, are an important research subject. Existing results treat these dimensions separately and there are only a few integrated proposals. This chapter presents a VQS called spatio-temporal visual query environment (S-TVQE), which allows the formulation of conv...

Normal aging impairs the representation and integration (binding) of spatial and temporal context in episodic memory. We directly compare age differences in episodic memory in relation to processing spatial and temporal context. As part of the COGITO study, 101 younger and 103 older participants trained an object-location serial recall task for 100 sessions. Training exacerbated the recall defi...

Solving real planning problems requires to consider spatial and temporal information. Indeed, to be solved more efficiently many real world problems need to take the action duration, the instants of effects occurrences, the instants of requiring preconditions. . . and the space in which the mission is accomplished by defining the different actions zones and know the path between these zones int...

A standard relation is two-dimensional with attributes and tuples as dimensions. A temporal relation contains two additional, orthogonal time dimensions, namely valid time and transaction time. Valid time records when facts are true in the modeled reality, and transaction time records when facts are stored in the temporal relation. While, in general, there are no restrictions between the valid ...
