Within this vision, computers and others digital technologies are integrated seamlessly into everyday objects and activities, hidden from our senses whenever not used or needed. An important facet of this vision is the interconnectivity of the various physical devices, which creates an Internet of Things. With the advent of Printed Electronics, new ways to link the physical and digital worlds became available. Common printing technologies, such as screen, flexography, and inkjet printing, are now starting to be used not only to mass-produce extremely thin, flexible and cost effective electronic circuits, but also to introduce electronic functionality into objects where it was previously unavailable. In turn, the growing accessibility to Personal Fabrication tools is leading to the democratization of...

The mouse and the keyboard are being replaced by touch and motion based interfaces, increasingly known as Natural User Interfaces (NUI). YDreams has developed Yvision, a platform that enables the development of natural user interfaces. YVision has a modular architecture matching YDreams technologies with the best of open source third party libraries. Our technologies emphasize the creation of smart interfaces using autonomous agents that go beyond the traditional reactive systems. Yvision also includes computer vision algorithms for motion detection and the application of 3D depth sensing in rendering engines. NUI applications involve: data acquisition using various sensors that detect the user's motion and gestures; interpretation of sensor data; and presentation, the end visualization layer. YVision includes augmented reality capabilities as a visualization component, where images are captured from the real world and enhanced in real-time with contextual information. Natural user interface applications, developed for both 2D and 3D depth sensing, will be presented for illustrative purposes. Applications include projects developed for clients such as Orange, Coca-Cola, Santander and Nike. Ongoing research projects focusing on digital signage and serious games will be also discussed.

In addition, one may try to satisfy other objectives, such as minimum environmental impact, better effluent reuse or adequate phasing. From the optimization point of view, the two main problems that render the solution difficult are the dimensionality and the concavity of cost functions. The matter has been dealt with by many authors, who have produced varied techniques to try to solve this problem. This paper begins with a brief review of the work of those authors who have produced models specifically designed to study the problem. Then, solution strategies are discussed concerning three major items: definition of the objective function and constraints, optimization method and practical aplicability of the models. The paper concludes with the discussion of topics for future research.

Additionally, it is easier to see that information spatially distributed where it makes sense, leveraging users of the task of searching for the context where the retrieved information can be applied. Augmented Reality (AR) is a technology that allows the superimposition of synthetic images over real images, providing augmented knowledge about the environment in the user’s vicinity. AR will also make the task more pleasant and effective for the user, since the required information is spatially superimposed over real information related to it. This short paper describes ANTS (Augmented Environments), an AR project for environmental management providing geo-referenced information to the user. The system’s architecture has a flexible design based on a client/server model, where several independent, but functionally interdependent modules are articulated. Therefore, modules can b...
