Wearable Computing  

As scientists develop the next wave of smartwatches and other wearable computing, they might want to continue focusing their attention on the arms and the wrists. According to a recent Georgia Tech study, portable electronic devices placed on the collar, torso, waist or pants may cause awkwardness, embarrassment or strange looks.

In a paper titled “Don’t Mind Me Touching My Wrist,” Georgia Tech researchers reported the results of a case study of interaction with on-body technology in public. Specifically, they surveyed people in both the United States and South Korea to gain cultural insights into perceptions of the use of e-textiles, or electronic devices, stitched into everyday clothing - no Google Glasses were tested in this study.

For the study, researchers directed participants to watch videos of people silencing incoming phone calls using e-textile interfaces on various parts of their body, including wrists, forearms, collarbones, torsos, waists and the front pant pocket. They were asked to describe their thoughts about the interaction (such as whether it appeared normal, silly or awkward) and its placement on the body.

In general, the study found that in both countries the wrist and the forearm were the most preferred locations for e-textiles, as well as the most normal placement when watching someone use the devices.

“This may be due to the fact that these locations are already being used for wearable technology,” said Halley Profita, a former Georgia Tech industrial design graduate student who led the study. “People strap smartphones or MP3 players to their arms while exercising. Runners wear GPS watches.”

According to the study:

• - Gender of the technology user affected opinions about the interaction. For example, Americans were uncomfortable when men used a device located at the front pant pocket region or when women reached for their torsos or collarbones.

• - South Koreans reported exceptionally low acceptance of women using the devices anywhere except for their arms.

• - Respondents expressed differing views on the most important factors on deciding how to use e-textiles. Americans focused on ease of operation and accessibility; South Koreans raised personal perception issues.

“South Koreans also said they wanted an easy-to-use system, but the technology should not make them look awkward or weird,” Profita said. “This isn’t surprising because their culture emphasizes modesty, politeness and avoidance of embarrassing situations.”

The findings were presented in September at the International Symposium in Wearable Computing in Switzerland. While at Georgia Tech, Profita was advised by Professors Ellen Yi-Luen Do and Thad Starner, a wearable computing pioneer. She is currently a doctoral candidate in computer science at the University of Colorado-Boulder.

The award-winning Frohne eClip brings the digital and analog world together. The super sleek USB flash drive also functions like a standard paper clip.

The Frohne eClip was recently honored the IDA11 Award and will be published in the IDA Book of Designs in 2013.

The eClip is lightweight and fits on your keyring. It functions like a regular paperclip to organize your reciepts, bills or other paper items.

Designed in Florida by Frohne, the eClip features a gold memory connector that is scratch resistant, extreme weather resistant, dust resistant, shock resistant, water resistant (salt & fresh water), alcohol resistant, and electromagnetic resistant

The Frohne eClip has data encryption, password protection, and computer lock.  It is sized at  61 x 12.5 x 2.1mm,  weighs 1.2g, and has a capacity of 8GB.  It is made of ABS and has a stated data retention of 10 years.  The device is certified by CE, RoHS, FCC.

Industrial designer and writer Shoham Arad interviewed Frog Design's, Jan Chipchase for Fast Company.

Recently, at the PopTech Conference in Camden, Maine, Chipchase, Frog's all-star field researcher, was giving a presentation on his travels in search of novel design solutions when a person in the audience lobbed a pointed question: “What is your motivation? Why do you do this?” When Chipchase began to respond, the audience member interrupted and asked again, “No, what is your motivation?” The follow-up hanging in the air was, “How do you sleep at night?”

Arad follows up with Chipchase to address these issues.

“It doesn’t take much effort to find something about globalization to be incensed about: Starbucks squeezing out your neighborhood coffee shop from the prime location; riots in Indonesia triggered by a stock market crash in Wall Street impacting oil subsidies. Coke logos being painted onto remote pristine mountain ranges. Make no mistake: Big companies, governments, organizations, agencies need watching, need to be held to account, and in many markets hold a disproportionate amount of power.” 

Chipchase has thought long and hard about these issues, and has a sophisticated view informed by millions of miles traveled. He believes that if those in the West aren't working with the emerging markets they’re developing for, the products suffer and people lose out. If we don't design for these markets, then the alternative for them is usually no design at all--and that means no designs solving their specific problems, and no economic might to prove their standing in the wider economy.

Core77 recently featured amazing illustrations by Graham Bleathman.

What separates Bleathman from the other artists I've featured is that his illustrations are almost cartoony. Obviously his source material isn't exactly very realistic, but he embraces that. Bleathman's color palette is light and playful, much like the television shows, and his cross-sections imagine a retro-futuristic world. The mechanics of the Thunderbirds or the Stingray submarine aren't that important, but it's the possibility that they could potentially exist that makes them wonderful.

 

Graham Bleathman is probably best known for his cutaways (cross-sections). He has always been inspired by this type of artwork and he was especially delighted when he was approached by Alan Fennell in the early 1990s to create new cutaways for the Thunderbirds Comic. At the time, Graham was producing cutaway artwork for the Bristol Evening Post newspaper on a variety of topics from Formula 1 cars to Cathedrals.
