Graphical Modeling Tools for Systems Biology
tl;dr
We survey the main graphical formalisms (supported by software tools) available to model biological systems with a primary focus on their usability, within the framework of modeling reaction pathways with 2D compartments. Expand

Usage of spatial information for selection of co-located devices
tl;dr
We focus on the use of spatial interfaces for identification and selection of devices a mobile user encounters in their immediate environment and show an overall user preference for the iconic map over the spatial and alphabetical list. Expand

Using a Spatial Context Authentication Proxy for Establishing Secure Wireless Connections
tl;dr
We introduce a context authentication proxy that is pre-authenticated with one of the devices and can authenticate with the other by shared context, and compare favourably to a standard, password-based approach. Expand

Integrating spatial information in a user interface
tl;dr
We propose an approach to integrate spatial information into the user interface in a spatially aware way. Expand
Demo Abstract: Spatial sensing to support interaction across devices
tl;dr
We have built a sensor network called Relate which provides fine-grained relative position information to co-located sensor nodes on the basis of peer-to-peer sensing. Expand
Collaboration with Spatial Aware UIs
In this paper we present results from the case studies of two homecare groups that have recently adopted the same workflow system. From these, we present evidence that the physical layout of theExpand
