Team invention has magic touchLocal | Sophie Hui 11 Jul 2017
Touchscreens are a common way of controlling electronic devices, but an invention by a team of young entrepreneurs allows you to use hand gestures to control laptops or tablets even if they are not in your hands.
The device - Welle - was developed by Maxus Tech, one of the winning teams in the One Million Dollar Entrepreneurship Competition organized by Hong Kong University of Science and Technology.
The team won the President Award and the Elevator Pitch Award.
Users' hand gestures will be recognized by embedded sonar, with the device turning any smooth surface, such as a wall, table, glass or even the user's thigh into a touchscreen control panel. Users can control their smartphones, laptops, tablets, music players or even lights from a distance.
The team is collaborating with a toy manufacturer to apply the technology in a remote control toy.
It hopes the technology can also be applied in homes and cars.
Maxus Tech will represent Hong Kong and attend the Grand Final at the HKUST Fok Ying Tung Research Institute in Nansha, Guangzhou on August 18 with two other winning teams - Clare.AI and Light Innovation Technology - to compete with competitors from Guangzhou, Beijing, Shenzhen and Macau.
Clare.AI has come up with a white- label chatbot while LIT has developed five-dimensional live cell imaging technology.
