Most existing devices are operated via touch screens, keyboards, mouse pads and other hand-based interfaces.

Researchers at the National University of Singapore have developed a smart mouthguard that could allow people to operate their devices using their mouth, instead of their fingers.

“Conventional input devices, such as touchscreens or voice recognition, are often challenging in certain environments or for users with limited hand function. Our goal was to develop a more flexible, user-friendly interface that can be operated using the tongue and teeth, which are capable of precise and fatigue-free movements.”
