Sensory helmet could mean firefighters are not left in the dark

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.Invented by a team of researchers at the Sheffield Centre for Robotics SCentRo, the helmet was inspired by research into tactile sensing in rodents, whose whiskers give early warning of potential hazards.Professor Tony Prescott of the University of Sheffield and director of SCentRo, said:

“When a firefighter is responding to an emergency situation he will be using his eyes and ears to make sense of his environment, trying to make out objects in a smoke filled room, for example, or straining to hear sounds from people who might need rescuing. We found that in these circumstances it was difficult to process additional information through these senses. Using the sense of touch, however, we were able to deliver additional information effectively.”

The team also found that the helmet was the ideal place to locate the vibrating pads because, although the fingertips might seem a more obvious choice, stimuli delivered to the wearer’s forehead enabled them to respond more rapidly to the signals, and would also leave their hands free for other tasks …

We have many devices now that enhance our existing human senses and abilities and this idea sounds like it has potential. The most exciting enhancement of human sesnes to me is the Internet and I think the next bigger enhancement will be artificial intelligence.
