The aim of this work is to provide jugglers with gestural control of music. This is based on the willing to control music by recycling mastered gestures generated by another art. Therefore we propose the use of a gestural acquisition system based on the processing of the electromyographic signal. The recordings are done during a three-ball cascade, of electromyogram from chosen muscles, which p...

Based on the current literature, it remains unclear whether electromyographic onset of the deep fibers of the multifidus (DM) is dependent on the direction of shoulder movement and the position of the center of foot pressure (CFP). In the present study, we re-examined the electromyographic onset of the DM during shoulder flexion and extension and investigated the influence of the CFP position b...

A method is described for logarithmically-amplifying electromyographic signals so that the most commonly-occurring events within them are enhanced selectively before digital conversion. There is a need to resolve low and intermediate levels of activity during chewing, while preserving the occasional high-level responses. Besides achieving a higher resolution in subsequent digital sampling, this...

Six human subjects performed a modified Fitts' test by moving an electromyographic signal between two targets on a computer screen. For five out of six subjects, the results were consistent with Fitts' Law with correlation coefficients ranging between 29% and 72%. The low correlation of the sixth subject (0.6%) may have been due to electrode misplacement and the adoption of a "strategy" in how ...

The surface electromyographic (EMG) signal is often contaminated by some degree of baseline noise. It is customary for scientists to subtract baseline noise from the measured EMG signal prior to further analyses based on the assumption that baseline noise adds linearly to the observed EMG signal. The stochastic nature of both the baseline and EMG signal, however, may invalidate this assumption....

Rather than merely imitating the desktop metaphor for mobile devices, new interface paradigms that take into account the particular characteristics of mobility, need to be developed. In this paper an input device based on the electromyographic (EMG) signal is proposed as a controller for mobile interaction. The interface can be considered subtle or intimate because individuals are able to inter...

OBJECTIVE The aim of this study was to evaluate the electromyographic activity of both the temporalis and masseter muscles and the mastication type of patients with skeletal unilateral posterior crossbite before and after orthodontic treatment and speech therapy. METHODS A total of 14 patients with skeletal unilateral posterior crossbite (eight females and six males), between 6-13 years of ag...
