Embodiments of the present invention disclose a method and an apparatus for determining a touch event in virtual space. The method comprises: detecting whether a preset trigger condition of detecting a touch event is met; when the preset trigger condition is met, acquiring initial three-dimensional coordinates and current three-dimensional coordinates of a slave device; calculating target three-dimensional coordinates corresponding to the current three-dimensional coordinates according to the initial three-dimensional coordinates; adjusting a virtual object corresponding to the slave device to a position indicated by the target three-dimensional coordinates in any specified coordinate system in the virtual space; when the position after adjustment is located inside a specified response area, converting the position after adjustment into a target response position; and triggering, at the target response position, the touch event in the virtual space. According to the method and the apparatus, whether the touch event occurs in the virtual space and the response position of the touch event can be determined according to motion of the salve device, thereby avoiding a touch event execution error in the virtual space due to omission or misjudgment of the touch event in the virtual space.
