### My Story

I am a PhD student, working with the Intelligent Robot Learning Laboratory (IRLL), under the guidance of professor Matthew E. Taylor. I was previously working with the Sustainable Product Life-cycle Design Lab on product disassembly design estimation.

### Research

Currently I’m interested in utilizing Reinforcement learning method to build an agent to learn how to make 3D CAD models under CAD software environment.

### Current Projects

By: Yang Hu, and Matthew E. Taylor

Taking a Computer-Aided Design (CAD) class is a prerequisite for Mechanical Engineering freshmen at many universities, including ours. To make the learning process easier and more interesting, we designed and implemented a tutorial for an open source CAD program, FreeCAD, to teach students how to use Boolean operations to construct complex objects from multiple simple shapes. Instead of teaching a single method to construct a model, the program first automatically learns all possible ways to construct a model and then can teach the student multiple ways to make the 3D model.

[BibTeX] [Abstract] [DOI]

This study evaluates the ability of users to self-install a smart home in a box (SHiB) intended for use by a senior population. SHiB is a ubiquitous system, developed by the Washington State University Center for Advanced Studies in Adaptive Systems (CASAS). Participants involved in this study are from the greater Palouse region of Washington State, and there are 13 participants in the study with an average age of 69.23. The SHiB package, which included several different types of components to collect and transmit sensor data, was given to participants to self-install. After installation of the SHiB, the participants were visited by researchers for a check of the installation. The researchers evaluated how well the sensors were installed and asked the resident questions about the installation process to help improve the SHiB design. The results indicate strengths and weaknesses of the SHiB design. Indoor motion tracking sensors are installed with high success rate, low installation success rate was found for door sensors and setting up the Internet server.
