Using pervasive computing to deliver elder care

Activity Recognition Based on Semi-supervised Learning

“…Activity recognition has gained a lot of interest in recent years due to its potential and usefulness for context-aware computing such as aged care monitoring [1] and smart homes [2]. Basically, the purpose of activity recognition is to infer people's behaviors from low-level data acquired through sensors in a given setting, based on which other critical decisions are made.…”

“…These methods include, but are not limited to: (1) remotely observe the scene using audio, visual, electromagnetic field, or other sensors and interpret the signal readings [3][4] [5], (2) attach sensors to the body and interpret the signal readings [6] [7][8], (3) attach sensors to objects and devices in the environment and interpret the sensor readings [9] [10].…”

A Dynamic-SOA Home Control Gateway

“…Also known as domotic, this subject has to deal with software and hardware concerns that try to improve the comfort, the quality of service and the security of the inhabitants of a house. A common example is a system that assists olderly at home so that they can be autonomous [6]. Another one is a software system managing the whole security of the home.…”

Automatic Recognition of Finger Gestures Using a Tri-Axis Accelerometer

“…Health support system has been studied widely in recent years [1], [2]. Two kinds of main supporting ways focus on speech-based communication and activity-based recognition.…”
