A device and method for preparing a low-impurity regenerated brass alloy through step-by-step insertion of an electrode are provided. The device includes a melt heating apparatus, an electrode displacement apparatus, and a pulse current generation apparatus. The automatic electrode lifting apparatus is controlled to adjust an insertion depth of the graphite electrode plate in the metal melt, and the pulse current generation apparatus is controlled to adjust the parameters of pulse current to achieve the impurity reduction on the metal melt. The preparation of a low-impurity regenerated brass alloy involves a short production process, simple operations, low energy consumption, and high impurity removal efficiency, and is suitable for regeneration and large-scale continuous production of non-ferrous metal alloys.

A touch interaction processing method, device, and system. The touch interaction processing method includes: receiving first information sent by an electromyographic signal collection device and second information sent by a location capturing device (); if it is determined that a time gap between a first touch start time and a second touch start time is less than a preset threshold, and a quantity of touch points that is corresponding to a hand gesture is the same as a quantity of touch points that is included in the second information, generating a touch instruction, where the touch instruction includes a device identifier of the electromyographic signal collection device, the hand gesture, and coordinate information of each touch point (); and performing an interaction operation corresponding to the touch instruction ().
