A projected target position of the handheld object is determined based on applying a translation factor, a zoom factor, and an offset to a position of a reference element of the handheld object detected by the camera on a two-dimensional plane. The translation factor is determined based on a difference between a calibration position on the plane and an initial position of the reference element corresponding to the calibration position, and is used to shift the position of the reference element to generate a projection target position. A scaling factor is determined based on an estimated length of an arm of a user holding the handheld object and is used to scale a position of the reference element to generate a projected target position. The offset is determined based on a polynomial equation and is used to extend the distance between the projection target position and the calibration position. 手持对象的投影目标位置基于将平移因子、缩放因子以及偏移应用于由相机在二维平面上检测到的手持对象的参考元件的位置而确定。平移因子基于平面上的校准位置和与校准位置对应的参考元件的初始位置之间的差异而确定，并且用来使参考元件的位置转移以生成
