Abstract: Wearable computing is introduced into the equipment maintenance task of manufacturing，design the wearable task assistant application system.Firstly，combine the wireless sensor network and wearable sensors to simulate the workshop experiment environment，build wearable computer system prototype.Secondly，the context characters of environment information entity are addressed，and then combine the technologies about domain ontology and fuzzy decision tree，present a new application build pattern of wearable task assistant application.Lastly，the application example with analysis is presented.

Key words: wearable computing, context aware, fuzzy decision tree, domain knowledge ontology
