A support infrastructure for the smart kindergarten

Abstract

A Support Infrastructure for the Smart Kindergarten C ontinuing progress in microelectronics has allowed the embedding of sensing, processing, and wireless communications capabilities in familiar physical objects. This enables the creation of smart environments, where communication and computation technologies facilitate interactions between people and their surroundings, instead of just person-to-person or person-to-server communication. In a collaborative project underway at the University of California, Los Angeles, called Smart Kindergarten (SmartKG), 1 we are exploring these technologies in a sensor-instrumented environment for early childhood education. Spatially dense but unobtrusive sensors continually capture interactions among students, teachers, and common classroom objects. The sensors deliver observations wirelessly to a wired infrastructure for analysis and storage. Two crucial building blocks of this environment are Sylph, a sensor middleware infrastructure, and iBadge, a lightweight sensor-instrumented badge worn by students and teachers.

Adaptive Audio-Based Context Recognition

“…1 For the second setting, the contexts of interest are fighting (aggression), loudness (such as drunken sport fans shouting), casual talk, and quiet.…”

“…For example, the iBadge [1] wearable system monitors the social and individual activities of children in a nursery school. It incorporates sensing, processing, communication, and actuating units.…”

“…The architecture employs a knowledge base to model various everyday human activities. The iBadge system discussed earlier is built with the Sylph architecture [1], which consists of sensor modules, a proxy core, and a servicediscovery module. Wang et al [5] propose the semantic space framework that consists of context wrappers, a knowledge base, aggregators, a context-query engine, and a context reasoner.…”

Prototyping Wireless Sensor Network Applications with BTnodes

“…Other researches have tried to set up a development platform that contains as many subsystems as possible (e.g., the I-Badge system [6]), inducing considerable system complexity and also interfacing constraints.…”

"Construção de aplicações de captura e acesso baseada em recorrência de funcionalidades"

“…Um exemplo é o Smart Kindergarten (Chen et al, 2002), no qual um ambiente de pré-escola é instrumentado para coletar informações sobre as crianças, os professores e os objetos com os quais eles interagem. Projetado para coletar, gerenciar e combinar dados obtidos pelos sensores, o objetivo do projeto é auxiliar educadores a investigar com profundidade o aprendizado dos estudantes.…”
