Abstract

AbstractThis research focuses on a long-standing problem at construction sites: on-site information retrieval. A wearable device, therefore, has been developed that can project the construction drawings and related information on the basis of the needs of the users. This device is envisaged to help engineers avoid carrying bulky construction drawings to the site, and to reduce the effort required in looking for the correct drawings to obtain the information they need. This device includes four modules: the information-integration module, the display module, the positioning module, and the manipulation module. The information-integration module is used to transfer information in the building information model (BIM) into images to enable the on-site retrieval from the device that was developed. The position module enables users to input their locations and automatically search for the images that the users might need. The manipulation module can analyze the gestures of the users from the touch screen and ac...
