Measurement of Work Efficiency in Remote Collaboration Using Hand Gesture and Smart Glasses

Abstract

In many existing systems, the helper can show the annotations to the worker with drawn lines, but their display is planar. Therefore, it is unsuitable for expressing the depth information or instructing complicated work to the worker. In this research, we have devised a system that can deal with conveying of complicated tasks which involve depth information to the worker by using the hand gestures of the helper. In order to evaluate the usefulness of the proposed system, we conducted comparative experiments on remote work support by instruction annotations using conventional method of drawn lines and the proposed method of using hand gesture instructions respectively. As a result, no significant difference was found between two methods in terms of the understandability of the instructions, however regarding working time, the hand gesture instructions were shorter by 17% on average than the other method.
