Hospital nurse following robot: hardware development and sensor integration
(Inderscience Enterprises Ltd., 2014)Hospital nurse regularly bring her instrument to the patient using cart. They need to push or pull the cart to the patient bed and bring it back many times in a day. This can be tiresome for nurses because they need to ... -
Lifting scheme for human emotion recognition using EEG
(IEEE Conference Publications, 2008-08)In recent years, the need and importance of automatically recognizing emotions from EEG signals has grown with increasing role of brain computer interface applications. The detection of fine grained changes in functional ... -
Patient monitoring in ICU under unstructured lighting condition
(IEEE Conference Publications, 2010-10)In this paper, fuzzy classifier is explained and reviewed for detecting facial changes of patient in a hospital in Intensive Care Unit (ICU). The facial changes are most widely represented by eyes and mouth movements. The ... -
Detection of facial changes for ICU patients using KNN classifier
(2010-06)This paper presents an integrated system for detecting facial changes of patient in a hospital in Intensive Care Unit(ICU).In this research we have considered the facial changes most widely represented by eyes and mouth ... -
Facial expression based computer cursor control system for assisting physically disabled person
(Institute of Electrical and Electronics Engineers (IEEE), 2012)Recent years, several researchers are developingc different kinds of assistive devices for physically disabled peoples. In this work, movement of illuminant markers through facial expressions is used to control the cursor ... -
Fuzzy linear programming: A modern tool for decision making
(Penerbit UTM Press, 2002-12)The modern trend in industrial application problem deserves modeling of all relevant vague or fuzzy information involved in a real decision making problem. In the first part of the paper, some explanations on tri partite ... -
Emotion detecting humanoid – the use of GPSO Algorithm
(Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)Recently, we implemented a real-time expert system that receives a live video stream of the face of a human subject and recognizes any of the six basic facial emotions expressed by the subject. The expert system ... -
Recognition of facial expression using neural network
(Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)In this paper, we attempted to recognize facial expression by using Haar-like feature extraction method. A set of luminance stickers were fixed on subject’s face and the subject is instructed to perform required facial ... -
Luminance sticker based facial expression recognition using discrete wavelet transform for physically disabled persons
(Springer Science+Business Media, LLC., 2012)Developing tools to assist physically disabled and immobilized people through facial expression is a challenging area of research and has attracted many researchers recently. In this paper, luminance stickers based facial ... -
GPSO versus GA in facial emotion detection
(Universiti Malaysia Perlis (UniMAP)School of Mechatronic Engineering, 2012-02-27)We recently proposed a modification to the widely known Particle Swarm Optimization (PSO) algorithm so that it can be applied as a method for facial emotion recognition. We named our proposed modification to PSO as the ... -
Nurse following robot: An automated robust control nurse following robot with self leveling platform, special wheel, suspension system and sensor integration for crowded hospital ward.
(Malaysian Invention and Design Society (MINDS), 2012-05-17)This Nurse Following Robot, is a personal robot allotted to a particular “person”, the nurse – which is not attainable with commercial hospital robots. The Nurse Following Robot is a personal robot for nurse. It searches ... -
