研究目的
Investigating the feasibility of using a small number of sensors to track movement and infer physical activity levels of older adults within their homes.
研究成果
The study demonstrates that a small network of low-cost, minimally obtrusive sensors can effectively monitor in-home physical activity of older adults. Optimal placement of three to four sensors can capture sufficient movement data to estimate activity levels with reasonable accuracy. The methodology is robust across different apartment layouts, suggesting potential for widespread implementation.
研究不足
The study's distance travelled metric is an approximation assuming straight-line travel between room centers. The method of data preprocessing, particularly the assignment of activities to locations, may introduce errors. The model's applicability to actual apartments depends on specific floor plans.
