Abstract: A haptic reproduction device includes a display module, a haptic reproduction module and a control module. The tactile sensation generation method includes: acquiring a position of a virtual functional area touched by a user and detected by the display module; outputting a first drive signal to the haptic reproduction module through the control module when the position of the virtual functional area touched by the user is an edge position of the virtual functional area, so that the haptic reproduction module generates a boundary tactile sensation; outputting a second drive signal to the haptic reproduction module through the control module when the position of the virtual functional area touched by the user is a middle position of the virtual functional area, so that the haptic reproduction module generates a haptic feedback.

Abstract: The present disclosure provides a method, device, and system for delaying signals as well as medical registration equipment, and belongs to the field of communication technologies. The method includes: determining, based on a clock period of each level of delay clock signals, a quantity of clock periods of each level of delay clock signals that are required for delaying a drive signal by a total quantity of delay phases; and delaying the drive signal by the determined quantity of clock periods of each level of delay clock signals sequentially. Therefore, on the premise that a data volume of a to-be-delayed drive signal is fixed, compared with a method for delaying signals by directly using a register, the method according to the present disclosure not only reliably realizes signal delaying, but also effectively reduces a quantity of required registers.
