NUS researchers develop new smart gaming glove

Science Innovations

A team of researchers from NUS, led by Professor Lim Chwee Teck, has developed a smart glove – called ‘InfinityGlove™’ – that allows users to mimic a variety of in-game controls using simple hand gestures. The InfinityGlove™, overcomes existing problems with weight and flexibility by weaving ultra-thin, highly sensitive microfibre sensors into the material of the glove. These sensors are not only lightweight and accurate, but also fulfil the role of wires thus reducing the need for additional wiring. Currently, the prototype weighs about 40 grams, and is flexible and comfortable.

Currently, each InfinityGlove™ contains a total of five thread-like sensors, one for each finger. This network of sensors can interface with the game software to produce accurate three-dimensional (3D) positions of a moving hand. Various gestures made by the user’s hands are then mapped to specific inputs that are found on a regular controller. To date, the team has mapped a total of 11 inputs and commands which will allow users to play games such as Battlefield V.

The application of this microfibre sensor technology is the breakthrough innovation that enables the InfinityGlove™ to accurately map finger gestures for human-machine interaction. The sensor is made up of a thin and stretchable rubber-like microfibre, about the same thickness as a strand of human hair, that is filled with a conductive liquid metal. A small electric current runs through the conductive liquid metal, creating an electrical reading signal that changes when the fibres are bent and as the liquid metal is displaced. This microfibre sensor was developed by the team back in 2017 and was previously used to measure pulse and bandage pressure, but they have since adapted it for the smart glove by improving the strain sensing capabilities. When linked up to the team’s proprietary software, the sensors can rapidly translate the gestures via electrical signals into command inputs at a speed that is almost the same as pressing a button on the keyboard. The InfinityGlove™ can be wirelessly connected to a computer and is lightweight.
