Tactile Helmet Could Help Firefighters Find Their Way

A specially-adapted 'tactile helmet', developed by researchers at the University of Sheffield, could provide fire-fighters operating in challenging conditions with vital clues about their surroundings.
The helmet is fitted with a number of ultrasound sensors that are used to detect the distances between the helmet and nearby walls or other obstacles. These signals are transmitted to vibration pads that are attached to the inside of the helmet, touching the wearer's forehead. Rescue workers, such as fire-fighters, who might be working in dark conditions or in buildings filled with smoke, will be able to use the signals to find walls and other obstacles that could help guide them through unfamiliar environments.

It is anticipated that a lightweight version of the technology could also be useful to people with visual impairments, acting as an additional 'sense' to guide users or to help them avoid hazards.
