Natural Language Interaction with a Construction Estimating Virtual Reality Environment

By Blake Howe - March 03 - Present
Committee: Dr. Tulio Sulbaran (Chair), Prof. Doris Kemp
Project Objective
The objective of this project is to develop a middleware application to enhance the educational experience of construction engineering students. The project will develop an avatar that will be embedded in a virtual reality environment for construction estimating. This avatar will be capable of understanding natural language and to answer questions of the students about construction materials and methods.


The users of virtual reality (VR) environments interact with them through pointing and clicking methods. However, there is a lack of capability in the VR environments to allow the users to interact using a natural language (conversation). The objective of this project is to create a piece of middleware that will allow users to communicate with VR environments through natural language (conversation). The software developed will have a degree of intelligence and making queries as close to natural language as possible. This will be achieved by applying decision tree logic and a series of algorithms for natural language processing to an avatar within a VR environment. This software will be linked with a VR environment focusing on construction estimating. Thus, it is anticipated that construction management students will be able to communicate with the VR environment using a natural language (conversation) to gain a better understanding of quantity estimating. In turn, the students and faculties will have a new tool that could enhance the educational experience.
