Digital pen based clock drawing test detection method and system

Abstract

The invention provides a digital pen based clock drawing test detection method. The method includes the following steps: 1) collecting handwriting data of a user clock drawing test; 2) identifying theoutline strokes, pointer strokes and number strokes of the handwriting data, and extracting stroke characteristics; and 3) performing detection on the outline strokes, the pointer strokes and the number strokes according to the stroke characteristics so that the clock drawing test can be achieved. A digital pen based clock drawing test detection system is also provided. The system includes a digital pen and information collecting equipment, wherein the digital pen is used for drawing figures, and the information collecting equipment is connected to the digital pen; the information collectingequipment includes a liquid crystal digital screen, a data collecting application and a data analyzing application; the handwriting data of the digital pen can be input and recorded by the liquid crystal digital screen; the handwriting data can be collected by the data collecting application; and the stroke characteristics of the handwriting data can be identified and marking can be performed through the data analyzing application.

Description

technical field [0001] The invention belongs to the field of digital medical treatment, and in particular relates to a detection method and system of a clock drawing test (CDT) based on digital pen traces. Background technique [0002] Technological innovations have played a major role in the advancement of telemedicine and nursing care. Especially in home care, technologies are available to monitor and control some chronic diseases, which effectively reduces the cost of medical monitoring (References: Kayyali, Basel, Zeb Kimmel, and Steve van Kuiken."Spurring the market for high- tech home health care."McKinsey Quarterly September(2011).). Home medical care technology can make people more proactive about their own health (reference: Horwitz, C.M., et al."Ishome health technology adequate for proactive self-care?."Methods InfMed 47.1(2008):58-62 .). For example, people can use an electronic sphygmomanometer to detect their own blood pressure at home to prevent stroke. Pe...

[0006] However, the current practice of neurological examination is still operated in the same way as ten years ago. Patients are required to use a pen to draw a clock on a given paper, which requires manual monitoring and analysis, which consumes manpower and energy, and the speed of judgment is slow. Moreover, the judgment is highly subjective, and the results of different cases may have large discrepancies and large errors.
