Abstract:
Provided are an electrical stimulation device configured so that a correspondence among finger motion and electrodes can be clarified in a short amount of time regardless of the state of attachment to a user's arm and an individual difference and an intended finger can be driven at high accuracy with very few erroneous operation and an electrical stimulation system using the electrical stimulation device. When an electrode probability matrix in which a Bayesian posterior probability indicating an electrode-finger correspondence is described as an element is updated in a host, the position of an element positioned on the upper left side of the electrode probability matrix and indicating that finger motion occurs is compared to rearrange the columns of the electrode probability matrix as necessary.

Claim (Index 3):
An electrical stimulation system comprising:\n an electrical stimulation device; and a host configured to transmit, to the electrical stimulation device, a command for generating an electrical stimulus, wherein the electrical stimulation device includes\n a band to be wound around an arm of a user, \n multiple muscle displacement sensors arranged on one surface of the band and configured to detect muscle displacement of the arm of the user, \n a sensor multiplexor configured to select one of the multiple muscle displacement sensors, \n multiple electrodes arranged adjacent to the multiple muscle displacement sensors on the surface of the band on which the multiple muscle displacement sensors are arranged, \n an electrode multiplexor configured to select one of the multiple electrodes, \n a near field communication receiving unit configured to receive a command for moving a finger from the host, \n a near field communication transmission unit configured to convert a signal obtained from each muscle displacement sensor and relating to the muscle displacement of the arm of the user into digital data to transmit the digital data to the host, \n an electrode probability matrix configured such that a correspondence among finger motion and the multiple electrodes is described in terms of probability, and \n a finger-electrode correspondence conversion unit configured to specify, based on the command for moving the finger, an electrode with a maximum probability from the electrode probability matrix and to control the electrode multiplexor to select the specified electrode, and \n the host includes\n a near field communication receiving unit configured to receive the data of each muscle displacement sensor from the electrical stimulation device, \n the electrode probability matrix, \n an input/output control unit configured to update an element of the electrode probability matrix after a shift of a current relative position relationship between the arm of the user and the electrical stimulation device has been detected to rearrange the element of the electrode probability matrix after the data of each muscle displacement sensor has been converted into the finger motion of the user, and \n a near field communication transmission unit configured to transmit the updated electrode probability matrix to the electrical stimulation device.
