Modified floyd algorithm for intelligent walking frame

Recently, the senior-friendly industry is expected to increase rapidly by population aging phenomenon. Especially, walking frame market for older people is expected to be even larger. Therefore, intelligent walking frame is proposed in this paper to guide through the shortest and comfortable path. Assuming that all the locations and its information given, the old tend to avoid difficult path such as uphill, stairs, obstacles, construction sites, etc. Consider this avoiding factors as some particular weights in Floyd algorithm will improve the performance in the desired direction. It is implemented commercially available walking frame added on guide system using modified Floyd algorithm. Applied this algorithm, although it may not the shortest path, can find easier and shorter path.
