Description

technical field [0001] The invention relates to three-dimensional interactive technology, in particular to a telescopic device, an operating rod and a measuring method. Background technique [0002] In recent years, the rapid development of portable mobile devices has also spawned many auxiliary input devices. As a traditional "input tool", the pen is widely used on various mobile phones and tablet computers after being specially designed. [0003] There are many types of input pens for traditional two-dimensional display, such as capacitive pens that can be used for capacitive touch screens, pressure-sensitive electromagnetic pens that can be positioned in the air to realize strokes, and the like. At present, these pen-shaped devices do not have the function of three-dimensional interaction. [0004] The three-dimensional interactive pen is a device used in the mature 3D display technology to interact with virtual objects displayed in 3D in a three-dimensional space. The ...
