Wearable support system for intelligent workshop application

In order for modern factories to meet the future intelligent requirements, wearable supporting technology is introduced to assist the technicians. Technicians could operate interaction electronic technical manual (IETM) and get remote technical support from the wireless local network. To allow the technicians work unencumbered by the device, Head mount display (HMD) and Voice user interface (VUI) are utilized for hands free operations and meet technicians´ requirements. What´s more, for the Voice user interface operates in the strong background noise environment, double microphone speech enhancement technology based on recursive least squares (RLS) algorithm is utilized to eliminate the noise. The result proved that the wearable system could increase user´s labor efficiency and reduce the cost for factories.
