Lovely Vintage Manuals Show How to Design for the Human Body

If you're designing something for people to hold and use, you probably want to make sure that it will fit a normal human. You don't want to make a cell phone that people can't hold in their hands (mostly) or a vacuum that will have you throwing out your back every time you clean the house. Ergonomics isn't just for your office desk setup; it's for every product you physically touch.

In the mid-1970s, the office of legendary industrial designer Henry Dreyfuss created a series of manuals for designers working on products that involved the human body. And now, the rare Humanscale manuals from Henry Dreyfuss Associates are about to come back into print with the help of a Kickstarter campaign from a contemporary design firm. Using the work of original Henry Dreyfuss Associates designers Niels Diffrient and Alvin R. Tilley, the guides are getting another life with the help of the Chicago-based design consultancy IA Collaborative.

A Humanscale page illustrates human strength statistics.

The three Humanscale Manuals, published between 1974 and 1981 but long out-of-print, covered 18 different types of human-centric design categories, like typical body measurements, how people stand in public spaces, how hand and foot controls should work, and how to design for wheelchair users within legal requirements. In the mid-20th century, the ergonomics expertise of Dreyfuss and his partners was used in the development of landmark products like the modern telephones made by Bell Labs, the Polaroid camera, Honeywell's round thermostat, and the Hoover vacuum.

IA Collaborative is looking to reissue all three Humanscale manuals which you can currently only find in their printed form as historic documents in places like the Cooper Hewitt design museum in New York. IA Collaborative's Luke Westra and Nathan Ritter worked with some of the original designers to make the guides widely available again. Their goal was to reprint them at a reasonable price for designers. They're not exactly cheap, but the guides are more than just pretty decor for the office. The 60,000-data-point guides, IA Collaborative points out, "include metrics for every facet of human existence."

The manuals come in the form of booklets with wheels inside the page that you spin to reveal standards for different categories of people (strong, tall, short, able-bodied, men, women, children, etc.). There are three booklets, each with three double-sided pages, one for each category. For instance, Humanscale 1/2/3 covers body measurements, link measurements, seating guide, seat/table guide, wheelchair users, and the handicapped and elderly.

"All products––from office chairs to medical devices—require designs that 'fit' the end user," according to Luke Westra, IA Collective's engineering director. "Finding the human factors data one needs to achieve these ‘fits' can be extremely challenging as it is often scattered across countless sources," he explains in a press release, "unless you've been lucky enough to get your hands on the Humanscale manuals."

Even setting aside the importance of the information they convey, the manuals are beautiful. Before infographics were all over the web, Henry Dreyfuss Associates were creating a huge compendium of visual data by hand. Whether you ever plan to design a desk chair or not, the manuals are worthy collectors' items.

The Kickstarter campaign runs from July 25 to August 24. The three booklets can be purchased individually ($79) or as a full set ($199).

7 Historic European Castles Virtually Rebuilt Before Your Very Eyes

While some centuries-old castles are still standing tall, others haven’t withstood the ravages of time, war, or natural disaster quite as well. To give you an idea of what once was, Australia-based insurance company Budget Direct has digitally reconstructed seven of them for its blog, Simply Savvy.

Watch below as ruins across Europe transform back into the formidable forts and turreted castles they used to be, courtesy of a little modern-day magic we call GIF technology.

1. Samobor Castle // Samobor, Croatia

The only remaining piece of the 13th-century castle built by Bohemia’s King Ottokar II is the base of the guard tower—the rest of the ruins are from an expansion that happened about 300 years later. It’s just a 10-minute walk from the Croatian city of Samobor, which bought the property in 1902.

2. Château Gaillard // Les Andelys, France

King Richard I of England built Château Gaillard in just two years during the late 12th century as a fortress to protect the Duchy of Normandy, which belonged to England at the time, from French invasion. It didn’t last very long—France’s King Philip II captured it six years later.

3. Dunnottar Castle // Stonehaven, Scotland

Dunnottar Castle overlooks the North Sea and is perhaps best known as the fortress that William Wallace (portrayed by Mel Gibson in 1995’s Braveheart) and Scottish forces won back from English occupation in 1297. Later, it became the place where the Scottish monarchy stored their crown jewels, which were smuggled to safety when Oliver Cromwell invaded during the 17th century.

4. Menlo Castle // Galway City, Ireland

This ivy-covered Irish castle was built during the 16th century and all but destroyed in a fire in 1910. For those few centuries, it was home to the Blake family, English nobles who owned property all over the region.

5. Olsztyn Castle // Olsztyn, Poland

The earliest known mention of Olsztyn Castle was in 1306, so we know it was constructed some time before then and expanded later that century by King Casimir III of Poland. It was severely damaged during wars with Sweden in the 17th and 18th centuries, but its highest tower—once a prison—still stands.

6. Spiš Castle // Spišské Podhradie, Slovakia

Slovakia’s massive Spiš Castle was built in the 12th century to mark the boundary of the Hungarian kingdom and fell to ruin after a fire in 1780. However, 20th-century restoration efforts helped fortify the remaining rooms, and it was even used as a filming location for parts of 1996’s DragonHeart.

7. Poenari Castle // Valachia, Romania

This 13th-century Romanian castle boasts one previous resident of some celebrity: Vlad the Impaler, or Vlad Dracula, who may have been an early influence for Bram Stoker’s vampire, Dracula. It also boasts a staggering 1480 stone steps, which you can still climb today.

The Smart Reason IKEA Mugs Come With a Chip on the Bottom

This IKEA mug has a low-key design element that might make your day a little easier.

IKEA might be best known for its array of ready-to-assemble furniture like beds, bookshelves, and desks, as well as the wafting scent of Swedish meatballs. But the popular household goods franchise also sells a steady number of coffee mugs. Most are unremarkable, including the spectacularly named VARDAGEN, and therefore never go out of style. But the VARDAGEN does have one odd feature. The 3.25-inch off-white stoneware mug comes with a chip on the bottom. Why?

According to Reader’s Digest, the chip has an official IKEA term: It’s called a drainage gate, and it has a very specific purpose.

The drainage gate was implemented so water wouldn’t collect on the bottom of the mug in a dishwasher. Since mugs are loaded upside-down, water has a tendency to pool on the bottom, which could conceivably result in a slightly splashy mess when unloading.

Because the “chip” is so smooth and uniform, it’s unlikely too many people mistake it for a damaged product. You can also find the drainage gate in the VARDAGEN teacup and saucer set.
