We will explain in detail and describe the design process and discuss the ultimate design interaction concept & development regarding (almost everything about) simplicity and playfulness of the inspaediers' experience to transform relevant information (related > meanfull > useful) in productive knowledge (inspiration > insight > foresight) in a very easy and quick way (usability: learnability; understandability; operability; attractiveness…), with a smile in the face (satisfaction) and a wow in the mind (or in the soul).

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.

A virtual ecosystem includes a three dimensional terrain model background, collections of man-made and natural objects, and behavior and interaction rules between the objects and the background. BITS is based on a virtual notepad and pen metaphor and is inspired in the concept of logging. Physical props are used to represent the notepad and the pen. The notepad includes a Time & Space Slider to facilitate time and space traveling, a set of buttons and a list of commands to control the interaction and enable the manipulation of objects, and a Notes Area. The handwritten notes can be referenced in time and space with the use of logging marks. BITS is being implemented on a PC-based architecture using sensors to track the pen's movement and the notepad's position. BITS maior problem is related to the poor representation of the notes written in the notepad using the sensor based tracking system.

However, the use of voluntary collected data is limited due to a lack of confidence in data collection procedures. Additionally, data quality is often unknown and the data are usually dispersed and nonstructured. Information and communication technologies (ICT) may promote the use of voluntary collected data through the development of a collaborative system that incorporates tools and methodologies to facilitate data collection, access and validation. Furthermore, the use of ICT may promote public involvement within environmental monitoring, since it facilitates communication among all the stakeholders. This paper analyses the role of ICT in developing a system for environmental collaborative monitoring intending to promote the use of volunteer collected data. It starts by analysing the role of volunteers within environmental monitoring and continues analysing the potential of ICT to take advantage of the benefits of using data collected by citizens. A collaborative system that allows the public to express its knowledge on the state of the environment is described. Special emphasis is given to tools that explore non-traditional types of environmental data such as images, sounds and videos in association with spatial information. To illustrate the above mentioned concepts, a case study for beach quality monitoring developed within the Senses@Watch project, is described.

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...
