In contrast to the view of big corporations promoting holistic \u201csmart city in a box\u201d solutions, this work proposes that smarter cities can be achieved by combining already available infrastructure, i.e., Open Government Data and sensor networks deployed in cities, with the citizens\u2019 active contributions towards city knowledge by means of their smartphones and the apps executed in them. In addition, this work introduces the main characteristics of the IES Cities platform, whose goal is to ease the generation of citizen-centric apps that exploit urban data in different domains. The proposed vision is achieved by providing a common access mechanism to the heterogeneous data sources offered by the city, which reduces the complexity of accessing the city\u2019s data whilst bringing citizens closely to a prosumer (double consumer and producer) role and allowing to integrate legacy data into the cities\u2019 data ecosystem.}, journal = {Future Generation Computer Systems}, author = {Aguilera, Unai and Pe\xf1a, Oscar and Belmonte, Oscar and L\xf3pez-de-Ipi\xf1a, Diego}, month = nov, year = {2017}, note = {00000}, keywords = {Legacy data, Q1, jcr4.639}, pages = {234--247} }']

An overwhelming supply of educational applications is designed to facilitate their autonomous learning in painting, counting, spelling and so on. Apparently, this approach is in line with the principles of Montessori education (independence, freedom and respect for the natural psychological development of the children). However, the well developed GUI interaction skills (tapping, swiping or pinching items through multi-touch gestures on a screen) of the 21st century children are useless for manipulating physical objects. Exploring the real world requires a different set of capabilities (e.g., fine prehensile skills), often developed through traditional toys and games. For this reason we have developed 3DU Blocks, a proposal that combines traditional toy blocks with the features provided by mobile devices to create new gaming experiences and open the door to explore new educational scenarios. 3DU Blocks is a library for color recognition in arrangements of traditional toy blocks, allowing to use them as a Tangible User Interface. As an early example of the capabilities of this library, we have developed 3DU Blocks Music, an educational game where players have to recreate simple melodies using toy blocks to represent musical instruments and notes. Therefore, the emphasis of Montessori in physical materials to help the autonomous learning process is combined with the immediate feedback and scaffolded challenges provided by the mobile application.}, booktitle = {{INTED}2013 {Proceedings}}, author = {Garaizar, Pablo and Pe\xf1a, Oscar and Romero, Jon Ander}, year = {2013}, keywords = {3DU Blocks, Mobile, Tangible User Interfaces, educational technology, image color analysis, learning, toy blocks}, pages = {5158--5164} }']
