---|---|---|
As part of a larger program of work to understand how people with dementia navigate their environment and use visual cues we present data which uses a single sensor - an IMU placed on the pelvis - to classify people into two groups on the basis of hesitancy when ascending/descending stairs: individuals with dementia vs age-matched controls. The classification was conducted on data collected from 34 people (14 controls; 20 people with dementia, comprising 10 with typical Alzheimeru0027s disease [tAD] and 10 with posterior cortical atrophy [PCA]) walking up a set of 4 steps. Attributes used to discriminate those with and without dementia were the mean and root mean square values of: resultant acceleration, roll, pitch and yaw. Each personu0027s data was allocated to one of two datasets (N=17, N=17). A weighted nearest neighbor classifier was trained on each dataset in turn and subsequently used on the remaining dataset. Overall accuracy of the classifier was 0.67, with a precision of 0.62 and recall of 0.47. |
