Moreover, since the ultrasonic sensor usually has a certain distance from the tip of the pen, even if it is operated on a flat surface, it will cause a large error due to the different inclinations of the pen body.
[0009] -Photographic method: a better method, but the structure is more complicated and the price is higher
In addition, because the reference object is always required to be within its line of sight, it also affects the use of
At the same time, methods such as image processing are also relatively complicated, and it is difficult to obtain high precision.

Embodiment Construction
[0018] Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.
[0019] figure 1 is a schematic diagram showing a pen interaction device according to an embodiment of the present invention.
[0020] Such as figure 1 As shown, the pen interaction device 10 according to this embodiment includes a pen-shaped housing 100, a pen tip 105 located at one end of the housing, at least two on-housing distance measuring devices 110-1 and 110-2 located on the housing, and a plurality of Out-of-shell distance measuring devices 120-1 to 120-5 (the example shown in the figure is 5), as well as a processing device and a sending device (none of which are shown).
[0021] The pen-shaped housing 100 is used to accommodate the main components of the pen interaction device 10, such as the pen tip 105, the distance measuring devices 110-1 and 110-2 on the housing, the processing device, and the information sending device. Of course...

The invention provides a pen alternating device which comprises a casing, a penpoint arranged at one end of the casing and distance measuring equipment, a processing device, a sensing device; wherein, the distance measuring equipment comprises at least two on-casing distance measuring equipment arranged at the casing and at least three outside-casing distance measuring equipment arranged at the outside of the casing, and the on-casing distance measuring equipment and the outside-casing distance measuring equipment send / receive distance measuring signals mutually. The processing device is usedfor confirming the space position states of the penpoint and the casing according to data obtained by the distance measuring equipment and converting the space position states into information which can be distinguished by a mainframe and the sending device is used for sending the information to the mainframe. Besides, the pen alternating device also can comprise a processing device and a pressure sensing device which is used for detecting the pressure born by the penpoint, and the penpoint is connected with the casing by the pressure sensing device. The processing device confirms the pressure state of the penpoint according to the pressure detected by the pressure sensing device and converts the pressure state into the information which can be distinguished by the mainframe, and the information is sent to the mainframe by the sending device.
Description
technical field [0001] The invention relates to a pen interaction device. Background technique [0002] Pen interaction technology is one of the important technologies of computer human-computer interaction. [0003] Earlier pen interaction technologies were mainly used for touch screens. The current pen interaction technology is also mainly used in touch screens of notebook computers, Tablet PCs, PDAs, and mobile phones. However, touch screen technology is a relatively complex technology, and the price is relatively high. Another problem is that without the touch screen, this kind of pen interaction technology cannot be used. [0004] People have also been exploring various pen interaction technologies away from the touch screen. Various pen interaction technologies utilizing methods such as electromagnetic induction, infrared rays, ultrasonic waves, and photographic equipment have also been continuously proposed. [0005] There are different disadvantages in the vario...
