The ability of robotic rehabilitation devices to support paralysed end-users is ultimately limited by the degree to which human-machine-interaction is designed to be effective and efficient in translating user intention into robotic action. Specifically, we evaluate the novel possibility of binocular eye-tracking technology to detect voluntary winks from involuntary blink commands, to establish winks...
To prevent learned non-use of the affected hand in chronic stroke survivors, rehabilitative training should be continued after discharge from the hospital. Robotic hand orthoses are a promising approach for home rehabilitation. When combined with intuitive control based on electromyography, the therapy outcome can be improved. However, such systems often require extensive cabling, experience in electrode...
Human visual system detects details in coloured images better. Sometimes interpretation of details in gray scale ultrasound images becomes harder. So in this work pseudocoloring of ultrasound images using empirical mode decomposition (EMD) is proposed. EMD doesn't use base function so it has more advantages than Fourier and wavelet transforms. The proposed method pseudocolored image by assigning two...
Many new devices come out with the idea of making more comfortable life. One of these ideas is an Myo Armband which is a wireless device for interacting with other devices such as smartphone or computer to use as a mouse, keyboard, or even game controller by using Bluetooth technology and electromyography (EMG) sensor. In order to communicate with computer, user has to pose his/her hand and arm to...
Main objective of this work is designing and implementation of low cost electromyography (EMG) signal acquisition system which provides multichannel facilities. The major challenges of this work are to meet the quality as well as the cost at the same time. Our designed acquisition system comes with some attractive features like real time data display, offline data store, and simultaneous use of three...
Literatures reviewing showed that excessive computer use, particularly mouse usage might be an occupational risk factor for carpal tunnel syndrome. The purpose of this study was to evaluate the wrist rest on EMG activities of forearm muscle and wrist postures while using computer mouse. Thirteen participants applied the computer mouse to play the FreeCell game for ten minutes on four conditions of...
Electrooculogram is record of eye movement using surface electrodes. EOG signals are analyzed in many areas using various methods. In this study, EOG signals were recorded from male and female volunteer university students before and after exam to examine capability of following visual stimulant. Volunteers followed visual test program on computer. In the meantime EOG signals were recorded simultaneously...
Getting visa or its renewal is one of the important elements for International students studying abroad. Each and every year students need to renew their visa, to extend their studentship in order to stay in a particular country. In Malaysia, in order to process visa renewal faster, Education Malaysia Global System (EMGS) was introduced by Malaysian Government. Since the implementation of EMGS in...
In this paper, we propose a vibrotactile stimulation system and explore the potential of combining it with volitional myoelectric control for robotic transtibial prostheses. The proposed system consists of six vibrators, three on the anterior side of the thigh and the other three on the posterior side. Six able-bodied subjects and two transtibial amputee subjects participated in the study, and three...
Many advanced EMG-based upper-limb prosthesis control methods require model training in which subjects produce supervised forces/movements. Since unilateral limb-absent subjects cannot produce forces/movements on their affected side, one technique (mirrored bi-lateral training) relates forces/motions produced on the sound side to EMG on the affected side. However, the efforts made by the phantom limb...
The complexity of emotion and its multi levels and multi modality of research, will inevitably lead to the multi orientation of study on it. This paper draw generalizations on the emotion physiological research based on EEG, ECG, GSR, RSP, EMG signals. The results show that: there is obvious mapping relationship between physiological signals and emotion and the physiological signals can more truly...
For the patients suffering from amyotrophic lateral sclerosis (ALS), they are encouraged to exercise their bodies routinely to prevent or delay the paralysis of muscles. This work proposes an electromyogram (EMG) based ALS rehabilitation system via playing computer games. The multi-channel EMG measuring system and the controlled interfaces to computer games were developed. According to the symptoms...
A classifier fusion interactive software package has been constructed for implementing the classification task in the electromyographic (EMG) signal decomposition process using the MATLAB high-level programming language and its interactive environment. The package employs classifier fusion schemes of multiple classifier combination for the purpose of fusing the decisions of a set of heterogeneous...
An automatic procedure for the spectral analysis of an all-night sleep electroencephalogram (EEG) is presented. This method relies on a fixed database initializing a procedure which adapts parameters so that they match to the signal to be analyzed. Parameters coming from database are normalized power spectra in predefined frequency bands. The novelty of our approach is to use flexible sleep stage...
This paper tackled the problem of establishing a computer brain interface using an Electroencephalography device for the purposes of interfacing with a computer using software developed in house for non-vocal quadriplegics. The hardware used was an Emotiv EEG that was used with a novel interface in order to establish some form of voice communications. The Emotiv headset was then tested using some...
In the field of cycling competition, cyclists commonly utilize binding pedals to maximize their competitive performance. The feature of binding pedals is to hold the sole of cycling shoe on the upper body of pedal, which enables a cyclist to not only push down the pedals but also pull up the pedals in one revolution of pedaling motion. Pedaling motion is implemented by the combination of muscle activities...
Spinal Muscular Atrophy (SMA) is a progressive neuromuscular disorder. Usually, this condition is considered genetically induced with no known cure to date. Children are born with the condition and develop muscular weakness progressively as they grow. The weakness ultimately encompasses the whole muscular function rendering the limbs dysfunctional or paralyzed. Many children with SMA, if they do not...
Detecting the stress of computer user in an office like environment will enable more development of computer and make it intelligent enough where it can interact with its user, taking users effective state in to account; known as affective computing. In this research work, we have analyzed physical and mental stress of a computer user in all day long working environment by analyzing variations in...
The sEMG (Surface Electromyogram) is a kind of physiological signal corresponding to the muscle action. The analysis of sEMG signal can obtain the charateristics of the motion information. In this paper, a remote control system based on sEMG was developed. The system consists of host and client computer. A sEMG signal recording device was designed. The recorded data was transit by Zigbee wireless...
At present there are various measuring devices or instruments that acquire the electrical activity of the heart (ECGs), but make a proper measurement, models the signs are printed directly on sheets of graph paper, unable to save the information for later analysis. In this work we make the development of a bioelectric signal acquisition, in this case focused on the signals emitted by the heart to...
