能测量绘画板位置信息的绘画板
摘要：
本发明涉及一种能测量绘画板位置信息的绘画板，属于计算机外围输入设备技术领域，该绘画板包括线路板、主控制器、位置信息传感器，其中，所述位置信息传感器焊接在所述线路板上，与所述主控制器连接，用于获知绘画板的旋转位置信息，并将其转换为电信号发送给主控制器；所述主控制器用于将所述电信号去抖处理并发送出去。本发明中当绘画板相对于电脑上显示的页面内容发生旋转，绘画板相对于地的位置信息也发生变化时，通过位置信息传感器获知旋转位置信息并将其转换为电信号发送主控制器，由主控器对该电信号进行去抖等处理，从而进一步实现电脑显示的页面内容发生与绘画板一致的旋转变化。
摘要（英）：

A coordinate input device and method able to obtain position information are disclosed. The coordinate input device is provided with a master controller, a position information sensor is set in the coordinate input device, the position information sensor is connected with the master controller, and converts the position signal of the position information sensor to the digital signal, sends it to the master controller, and the master controller removes jitter from the digital signal sent by the position information sensor, sends it to the computer for processing, and obtains the position information of the coordinate input device. By the position information sensor obtaining its position information, converting it to the digital signal and sending it to the master controller, the master controller removing jitter, etc., from the digital signal and sending it to the computer, the computer performing the further process, the rotating change occurred by the page content displayed by the computer consistent with the coordinate input device can be realized.
