A ceiling sensor system is reported in this study to recognize different activities of multiple persons in the home environment. The sensors output binary sequences by which we know the existence/nonexistence of persons under the sensors. A short-period average of the binary response is shown to be regarded as a pixel value of a top view camera, but the camera-like view is more advantage in the sense...
This paper presents a control scheme using human arm dynamics to simulate the subject's volitional movement. To achieve this goal, first, it has to obtain the torques purely generated from the subject from force/torque sensors. With this result, the controller can implement the therapeutic exercises, consisting of the active range of motion (AROM), the active-assistive range of motion (A-AROM), and...
This paper presents a color-science-based approach to feedback control design of color-tunable LED lighting systems for smart spaces. The general design problem is posed as the minimization of a cost function consisting of metrics that capture light quality, energy consumption and human comfort. A linear light transport map is used for modeling and identifying the optical fingerprint of the room....
With the advancement in the technology, various types of sensors are easily available in the market to detect air pollution with precise reading of different gases in environment but main problem arises in efficient use of sensor network so that it can sustain for a longer time and effective communication strategy for these sensor node to base station so that collected data can process efficiently...
Emotion is an essential element of human behaviours. In this research, we investigated human behaviours related with the touch interface on a smartphone as a way to understand users' emotional states. As modern smartphones have various embedded sensors such as accelerometer and gyroscope, we aim to utilize data from these embedded sensors for recognizing human emotion and further finding emotional...
Architectural guidance for the development of fusion and resource management systems exists, yet the automated management of their policies remains nascent in the Joint Directors of Laboratories (JDL) model. We present an architecture to assist design of fusion and Command and Control (C2) systems grounded in an understanding of human intent and Artificial Intelligence (AI) literature. The policy...
Flock Logic is an art and engineering project that explores how the feedback laws used to model flocking translate when applied by a group of dancers. The artistic goal is to create tools for choreography by leveraging dynamics of multiagent systems with designed feedback and interaction. The engineering goal is to develop insights and design principles for multi-agent systems, such as human crowds,...
Context-aware applications have been the focus of extensive research, yet their implementation in mobile devices usually becomes challenging due to restrictions of processing and energy. In this work, we present, demonstrate, and evaluate a mobile platform for real-time human activity recognition. The evaluation results indicate that the system can be implemented in real scenarios meeting accuracy,...
Autonomous mobile robots are often equipped with sophisticated sensors designed to provide the system with a model of its surrounding environment. This information can then be used for making task-related decisions and conveying information back to the operator. To date, autonomous systems tend to exceed at well defined tasks such as navigation, planning, and obstacle avoidance, usually in fairly...
This paper presents an investigation of a research project titled “Innovative Seating Systems” by BMW Group “Research and Technology” Team. It is based on my idea and reports about “Benefits of using Bionic Seats in Roadster cars” which is submitted and accepted by BMW Group Co-Creation Lab in March 2010. In this paper, three BMW Group revolutionary innovative seating systems, Bionic Seat, Ergo Seat...
Walking power assist leg (WPAL) [1]-[5] is designed for old people, patients with weak legs or normal humans power augmentation during walking. The control system of WPAL is mainly developed to enhance the mobility because the field of activities of WPAL assistance is expected to be like outdoors activities. So the portability is very important, and the control system of WPAL should be small, light...
Gait recognition and analysis is one of the most important biometric methods for medical treatments, virtual reality games and human motion identification. Gait recognition based on wearable MEMS inertial sensors is proposed for medical rehabilitation with Physical Activities Healthcare System (PATHS) in this paper. We use relative wavelet energy as features for support vector machine (SVM) recognition...
To provide the adapted mobility assistance to people who are in need of, information of specific physical characteristics of users are essential. In this work, we focus on extracting approximate human physique using low-cost sensors. We use Microsoft Kinect to detect and follow human in an indoor environment and measure her/his height and movement speed. Measured height could be used for adjustment...
The aim of this project is to interface the human arm with a machine wirelessly and that machine in turn will mimic the motions of the human arm as accurately as possible. The idea for this prototype was got from NASA's ROBONAUT which is a highly dexterous robot being used on the International Space Station [5], [6]. Human Machine Interface used for robots is usually done using a joystick or a master...
In this paper, we proposed a pointing interaction system which allows users to control devises in Intelligent Space by using hand pointing. This system consists of multiple camera devices and a pan-tilt projector. This system recognizes user's face, user's head orientation and a spot where user points with the camera devices. However, to achieve a real interaction, an intuitive feedback is required...
A human being is a complex system [1] made up of cells, tissues, organs and organ systems that function together to maintain the health, defined as an optimal predictive fluctuation [8], of this system. The coordinated physiological processes maintain most of the steady states in an organism, not at a fixed value, but within a narrow, relatively constant range. This is broadly known as homeostasis...
Contextual information is important for interpreting human actions especially when actions exhibit interactive relationship with their context. Contextual clues become even more crucial when videos are captured in unfavorable conditions like extreme low light nighttime scenarios. These conditions encourage the use of multi-senor imagery and context enhancement. In this paper, we explore the importance...
This study proposes a "pure skill-based" fuzzy logic control (FLC) approach to reverse a car-like mobile robot(CLMR) into an empty parking bay automatically. The FLC approach was expressed in the form of fuzzy rules based on the knowledge of skilled human drivers. Range measurements were provided to help the CLMR avoid collisions during the parking. Simulations proved the effectiveness of...
We propose a new utility-based routing protocol for Delay Tolerant Networks which maximizes the expected number of selected nodes being likely to finally encounter to destination nodes based on the optimal stopping theory. Our previous investigation by analyzing real experimental data showed that frequencies of human contacts generally followed a power-law distribution \cite{FM2011}. Since the power...
Abnormal gait leads to falling which can cause of human's injury. Normally human has resembled gait cycle between walking. But if human has falling or abnormal walking that gait cycle is not resemble the normal walking. The walking gait can calculate the locus of the Zero Moment Point (ZMP) and the ZMP can be estimated by the signal from low-cost Force Sensitive Resistors (FSRs). Four FSRs were installed...
