Digital pen-based clock drawing test detection method and system

Abstract

The present invention provides a digital pen-based clock drawing test and detection method, the steps comprising: 1) collecting handwriting data of the user's clock drawing test; 2) identifying outline strokes, pointer strokes and digital strokes of the handwriting data, and extracting stroke features; 3) According to the characteristics of the strokes, the outline strokes, pointer strokes and digital strokes are detected to realize the clock drawing test. The present invention also provides a digital pen-based clock drawing test and detection system, including: a digital pen for drawing graphics; an information collection device connected to the above-mentioned digital pen, including a liquid crystal digital screen, a data acquisition application and a data The analysis application is to input and record the handwriting data of the digital pen through the liquid crystal display, collect the handwriting data through the data collection application, and identify and score the stroke characteristics of the handwriting data through the data analysis 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.
