Applying Graph Theory to Interaction Design
نویسندگان
چکیده
Graph theory provides a substantial resource for a diverse range of quantitative and qualitative usability measures that can be used for evaluating recovery from error, informing design tradeoffs, probing topics for user training, and so on. Graph theory is a straight-forward, practical and flexible way to implement real interactive systems. Hence, graph theory complements other approaches to formal HCI, such as theorem proving and model checking, which have a less direct relation to interaction. This paper gives concrete examples based on the analysis of a real non-trivial interactive device, a medical syringe pump, itself modelled as a graph. New ideas to HCI (such as small world graphs) are introduced, which may stimulate further research.

Introduction: Graph theoretical analysis of functional Magnetic Resonance Imaging (fMRI) data has provided new measures of mapping human brain in vivo. Of all methods to measure the functional connectivity between regions, Linear Correlation (LC) calculation of activity time series of the brain regions as a linear measure is considered the most ubiquitous one. The strength of the dependence obl...

In the present paper, a class of hybrid, nonlinear and non linearizable dynamic systems is considered. The noted dynamic system is generalized to a multi-agent configuration. The interaction of agents is presented based on graph theory and finally, an interaction tensor defines the multi-agent system in leader-follower consensus in order to design a desirable controller for the noted system. A...

In this article fluid-structure interaction of vibrating composite piezoelectric plates is investigated. Since the plate is assumed to be moderately thick, rotary inertia effects and transverse shear deformation effects are deliberated by applying exponential shear deformation theory. Fluid velocity potential is acquired using the Laplace equation, and fluid boundary conditions and wet dynamic ...
