To achieve this goal, we take advantage of the current commercial sensor features (reliability, low consumption, easy integration, etc.) to develop a series of sensor-based low-cost devices. Specifically, our prototype system consists of a tower of cubes augmented with wireless sensing capabilities and a mobile computing platform that collect the information sent from the cubes allowing the later analysis by childhood development professionals in order to verify a normal behaviour or to detect a potential disorder. This paper presents the requirements of the toy and discusses our choices in toy design, technology used, selected sensors, process to gather data from the sensors and generate information that will help in the decision-making and communication of the information to the collector system. In addition, we also describe the play activities the system supports.<\/jats:p>","DOI":"10.3390\/s16111953","type":"journal-article","created":{"date-parts":[[2016,11,21]],"date-time":"2016-11-21T11:16:05Z","timestamp":1479726965000},"page":"1953","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Smart Toys Designed for Detecting Developmental Delays"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7076-9048","authenticated-orcid":false,"given":"Diego","family":"Rivera","sequence":"first","affiliation":[{"name":"Departamento de Autom\u00e1tica, Escuela Polit\u00e9cnica Superior, Universidad de Alcal\u00e1.
