Researchers from Taiwan have developed a machine that reads people’s hand gestures and thereby permits them to open doors by waving a few fingers:
“In the future, you won’t have to worry about losing or forgetting your keys,” said Tsai Yao-pin, who teaches at the Technology and Science Institute of Northern Taiwan.
At the heart of the technology developed by his team is a chip that can detect movement in three dimensions, as used in Nintendo’s Wii video game console, he said.
The technology allows users to easily unlock their doors by repeating a gesture preset in the sensor, according to Tsai.
You’ll just have to be careful about your body language.
