Virtual learning: Using AI to teach Chinese
troy (new york) — To learn Chinese in this room, talk to the floating panda head.
The Mandarin-speaking avatar zips around a 360-degree restaurant scene in an artificial intelligence-driven instruction program that looks like a giant video game. Rensselaer Polytechnic Institute students testing the technology move inside the 12-foot-high, wraparound projection to order virtual bean curd from the panda waiter, chat with Beijing market sellers and practice tai chi by mirroring moves of a watchful mentor.
“Definitely less anxiety than messing it up with a real human being,” says Rahul Divekar, a computer science graduate student working on the project. “So compared to that anxiety, this is a lot more easy.”
The “Mandarin Project” is a joint venture of RPI and IBM. Cognitive and Immersive Systems Laboratory researchers are developing a sort of smart room that can understand students’ words, answer their questions and perceive their gestures. Lessons are presented as games or tasks, like ordering a meal out.
Divekar orders Peking duck — “Beijng kaoya” — and the panda fetches the virtual dish. Divekar says the food was good — “Cai hen hao chi” — but he can’t pay the bill. No problem, the panda replies — “ni keyi xi pan zi” — you can wash the dishes.
Other scenes include an outdoor market and a garden, each a high-tech twist on cultural immersion.
“Our plan is to complete several scenes of real life in China, to let the student be able to have a virtual trip over there,” says Hui Su, director of the lab at RPI.
Tests on the room with students studying Mandarin will continue this school year as they work on additional scenes, including an airport. A six-week course is being readied for the summer.
Artificial intelligence, or AI, is ubiquitous in everything from callcenter chat-bots to home assistants. Even some language instruction products on the market feature AI or virtual reality.
The Mandarin Project is notable for its scale and sophistication. Computers simultaneously interpret speech and gesture to keep a dialogue going. When a student points to a picture and asks “What’s that?” computers can come up with an answer.
