Courtney Owen began thinking about how robots could help humans when she was a student in high school. While working a summer job in a research lab in Fort Worth, Texas, she met Zeno, a robot that helps children with autism improve their social communication.

Owen was surprised and excited to encounter Zeno again as a first-year student at 成人AV.听, the associate professor of听听who works with Zeno, was featured in a video shown at a dinner during orientation week. She quickly reached out to Mahoor and began working in his lab that year.

鈥淚鈥檝e been interested in the intersection of robotics and human interactions 鈥 also known as socially assisted robotics 鈥 for a long time,鈥 says Owen, now a junior. While in Mahoor鈥檚 lab, she worked on Zeno鈥檚 programming and also started to build a chatbot 鈥 a computer program designed to simulate conversation with human users.

That work eventually led her to design her own research project: to develop the code for a dialogue-management system that could let a robot or a computer application talk to elderly people. She hopes eventually the system will help older people get the social interaction they need 鈥 especially those who are reluctant to talk to a mental health professional.

Aided by a 成人AV summer research grant, she worked on the project in summer 2017. The grant provided her with living expenses so she could devote her summer to full-time, intensive research. Awarded by 成人AV鈥檚听Undergraduate Research Center, summer research grants provide students with up to $3,500 each to support their work and to cover expenses. This year, 45 students received grants in 11 different disciplines ranging from art to physics and astronomy.

鈥淲ith this grant, the only constraints were time and my own abilities,鈥 Owen says.

A person interacts with the chatbot through a series of yes/no questions and questions with limited responses. 鈥淔irst the chatbot introduces itself, and then it takes you through a PHQ-9 test, which is a depression indicator test,鈥 Owen says. From there, Owen integrated questions and guidance recommended by mental health counselors.

The chatbot is the first step in what Owen hopes will become a larger project accessible to a wider audience. 鈥淥nce I finish this prototype, I will use a website that allows you to enhance your chatbot using artificial intelligence鈥 she says. When the code for the prototype chatbot is complete, Owen can program a computer, or even a robot, to interact with an elderly user.

At the end of the summer, Owen met with Stanford University professor Alison Darcy to discuss a program Darcy designed called Woebot that is similar to her own. Darcy and Owen discussed the different audiences that could benefit from Woebot. 鈥淪he wants to change Woebot to make it more tailored for elderly people, which is the group I have been focusing on for my project,鈥 Owen says.

Owen says her summer research experience has left her feeling prepared for her future. 鈥淏eing able to conduct research has really shown me what being an engineer can be like,鈥 Owen says. 鈥淎fter having created a basic prototype that I will continue to build upon, I feel much more confident in my abilities to tackle any problem that comes my way, be it in a future class or my future career.鈥
