Abstract: Disclosed is tuning and matching devices and methods, magnetic resonance imaging (MRI) equipment, and display interaction devices. The MRI equipment may include a transmitting coil. The tuning and matching control device may be connected with the transmitting coil and configured to perform tuning and matching on the transmitting coil. The display interaction device may be in a scanning room. The tuning and matching method may include: first obtaining curve information of a tuning curve, if determining that the curve information of the tuning curve to be displayed is not within a set information range, adjusting layout information of the tuning curve to be displayed in a display interface, and displaying the adjusted tuning curve in the display interface.

Abstract: A virtual object control method includes obtaining a panel presentation instruction generated through triggering on a user interface (UI) and presenting an interaction control panel on the UI in response to the panel presentation instruction. When an interaction button or a movement on the interaction control panel is triggered, and the interaction button is associated with an object selection panel, the interaction control panel is replaced with the object selection panel in the UI. A to-be-controlled virtual object is selected through the object selection panel and the selected virtual object to perform interaction is controlled according to an interaction corresponding to the interaction button.
