THCB3	Improving Web2cHMI Gesture Recognition Using Machine Learning	controls, toolkit, interface, TANGO	148
	R. Bacher DESY, Hamburg, Germany
	Web2cHMI is multi-modal human-machine interface which seamlessly incorporates actions based on various interface modalities in a single API, including finger, hand and head gestures as well as spoken commands. The set of native gestures provided by off-the-shelf 2D- or 3D-interface devices such as the Myo gesture control armband can be enriched or extended by additional custom gestures. This paper discusses a particular method and its implementation in recognizing different finger, hand and head movements using supervised machine learning algorithms including a non-linear regression for feature extraction of the movement and a k-nearest neighbor method for movement classification using memorized training data. The method is capable of distinguishing between fast and slow, short and long, up and down, or right and left linear as well as clockwise and counterclockwise circular movements, which can then be associated with specific user interactions.

THP14	Development of the New Spill Control Device for J-PARC MR	controls, operation, interface, status	192
	T. Kimura KEK, Ibaraki, Japan
	J-PARC Main Ring (MR) is there are two operation modes of the fast extraction (FX) and slow extraction (SX). The SX operation used the spill control system. It consists of two kinds of Extraction Quadrupole Magnet (EQ), Ripple Quadrupole Magnet (RQ) and Spill Control Device with Digital Signal Processor (DSP) which calculates and controls it the optimal current pattern using the monitor signal of an extraction beam. It is used to make flatten the extraction beam structure and reduce the ripple noise. The present Spill Control Device needs to be reviewed from the aspect of service life etc. In this presentation, we will focus on improving the versatility of the device and the operability of the DSP program, and explain the development of the next-generation spill control device.

Web2cHMI is multi-modal human-machine interface which seamlessly incorporates actions based on various interface modalities in a single API, including finger, hand and head gestures as well as spoken commands. The set of native gestures provided by off-the-shelf 2D- or 3D-interface devices such as the Myo gesture control armband can be enriched or extended by additional custom gestures. This paper discusses a particular method and its implementation in recognizing different finger, hand and head movements using supervised machine learning algorithms including a non-linear regression for feature extraction of the movement and a k-nearest neighbor method for movement classification using memorized training data.
