The development of an optical fiber specklegram sensor for the assessment of force myography signals is reported. The device consists of microbending transducers attached to the user forearm by means of Velcro straps. The muscular stimuli generated in response to hand movements cause the fibers to be mechanically pressed by the deformer structures, resulting in light modulation. The optical signals...
The global water shortage has recently been debated at the United Nations. The main cause of this shortage is the excessive use of water resources by humans. Therefore, a positive approach to saving water is needed. Much water is used to flush toilets in homes. Thus, it is necessary to develop a sewage disposal system that saves water. We focused on the bowel peristalsis as a model for a mechanism...
In this paper we present a quantitative analysis of electrode positions on the side of the face for facial expression recognition using facial bioelectrical signals. We show that distal electrode locations on areas of low facial mobility have a strong amplitude and are correlated to signals captured in the traditional positions on top of the facial muscles. We report on electrode position choice as...
In this paper, we introduce a novel technology to convert bioelectrical signals into sound and its application in biofeedback. The surface electromyogram is adopted as the bioelectrical signal and converted into an auditory signal. The sound conversion occurs inside a wearable device. In general, visual feedback can provide more information than acoustic feedback, however, we assume that the latter...
This paper presents part of an on-going project to design a wearable supportive device, in particular for the facial paralyzed patients to enhance facial expressiveness. As various complications can result in facial disfigurement and loss of functionality in facial muscles it is required to develop a supporting device for people with such conditions. The previously proposed robot mask, which consists...
Expression based non verbal communication accounts for a significant amount of the information exchange in human communication. In order to recreate facial expressions artificially for conveying an exact message it is necessary to make them as natural as possible since human beings posses a remarkable ability to recognize the emotion from an expression. In this paper we try to analyze facial expressions...
The face is such a salient feature of a person that it plays a crucial role in physical, psychological, and emotional makeup. Hence facial paralysis, which is the loss of voluntary muscle movement of one or both sides of the face, apart from making physical disturbances, can also be an alarming and depressing event in onepsilas life. Although therapeutically and surgery based treatment methods are...
