computational clock drawing analysis for cognitive impairment screening
This paper presents computational support for the Clock Drawing Test (CDT), a simple cognitive dysfunction diagnosis tool. Despite its popularity of current use, the CDT has been administered the same way for the past three decades as a pencil-and-paper test. By making a computerized drawing test, we can understand the process of clock drawing construction rather than simply analyzing the final drawing. In this paper, we will first introduce our computerized Clock Drawing Test, the ClockReader. Then, we will describe two automated data-capturing methods with specific data examples. The automated data analysis can provide neuropsychologists with useful qualitative information, such as the process of drawing, as well as patients' planning strategies.
