Nissan using special suit to simulate elderly drivers

Much like the automotive crash test industry utilizes "dummies" of different statures and body weights to simulate different passenger types, Nissan engineers have developed a special suit to "simulate" the elderly. Nissan went to all this trouble because it anticipates that Baby Boomers will soon command a larger share of automotive sales. It's a preemptive plan to design vehicles that accommodate their needs. Well, some of them, as we don't expect in-dash prune juice dispensers anytime soon.

This innovative suit is comprised of several different components that are each designed to restrict physical movement or reduce vision (interestingly enough, donning the suit does not make the wearer crave early bird specials or migrate to Palm Springs). Dark colored glasses simulate the poor vision and gloves simulate reduced dexterity. Casts on on the body also weigh down the wearer's limbs to simulate arthritic pain. Our favorite is the big thick waist belt designed to simulate the "middle aged spread."

Nissan Engineers use Special Suit to Simulate the Elderly

Nissan's 'Perfect Fit' For Baby Boomers

Baby boomers are commanding a bigger share of automotive sales worldwide and Nissan is meeting their needs with some lateral thinking.

Nissan engineers in Japan are using a special 'suit' that simulates the physical effects of ageing. It allows engineers and designers to see car ownership through the eyes of older customers and then alter features to accommodate special needs.

Nissan Design Engineer Etsuhiro Watanabe said, "As we get older, it can become harder to perform physical maneuvers. When it comes to driving, that can mean more difficulty seeing writing on the switch gear, reach and use controls, distinguish colors on navigation equipment or get in and out of seats.

Mr Watanabe said many engineers were in their 20s and 30s and the suits provided an accurate reflection of the daily physical challenges not necessarily experienced by young drivers.

"It's not always practical to recruit older motorists for product research," he said, "so these special suits allow Nissan's engineers and designers to come up with solutions that make car use a safer and more positive experience."

"This is a critical part of our vehicle research and shows Nissan is alert to the changing needs of drivers and at the leading edge of vehicle development."

The suits can simulate poor balance through a raised front-toe design, cataract goggles simulate failing eyesight, casts on the body simulate arthritic pain by making it more difficult to raise arms and legs, and color-deficiency goggles simulate problems distinguishing colors.

Nissan engineers wearing the suits have been experimenting with the location and angles of switches, testing the ease of reading instrument and navigation panels and determining where to locate grips to make it easier to get in and out of a vehicle.

The suits are being used by engineers at the Nissan Technology Center (NTC) outside Tokyo. Work at the Centre accelerates research and advances the engineering of breakthrough technologies for Nissan's next generation of products.

One feature of the suit is a thick waist-belt. About 250 mm wide and 50 mm thick it does an excellent job of duplicating what is euphemistically known as the 'middle aged spread'. The belt makes it harder to enter or exit a car and can even cramp an engineer's movement behind the steering wheel in poorly designed seating.

The special suit also stiffens the engineers' flexibility, particularly with later-in-life susceptible knees and ankles. Restrictions are also created at the elbows using a complex system of levers. Checking on neck movement is also important as it can influence how well a driver is able to use the door mirrors and how easy - or difficult - it is to look back whilst reversing.

Naturally, the research suits also give an insight into problems faced by partially disabled drivers of any age.
