To represent an FTCN, a directed graph is generally used. In this graph, each node corresponds to a variable while the arcs represent a binary constraint between two variables. Definition 2. A 𝜎σ-possible solution of FTCN 𝒩N is defined as an n-tuple 𝑠=(𝑥1,…𝑥𝑛)∈ℝ...
Nonetheless, at the present time, a seamless integration of NUI-based interaction in common applications or in the application development workflow is often difficult to observe or achieve. What is missing is a type of flexible software layer able to "augment" the interaction possibilities for (...

Indeed, the design of ever more pervasive and natural interaction mechanisms will play an important role in the future of HCI. This trend is today witnessed by the mass-market diffusion of a number of consumer products integrating components generally used to build NUIs, such as touch sensors an...
