At the Expo 2012 in Korea, Hyundai Motor Group staged a mind-blowing display using a controller area network (CAN) called mechatronic. This is a message-based protocol originally designed for automotive applications and now also used in areas such as industrial automation and medical equipment. Hyundai’s Hyper-Matrix installation was designed by Seoul media arts firm Jonpasang. In just two months, the team built a mammoth three-sided display out of thousands of Styrofoam blocks that could be manipulated like pixels.The 11-inch cubes were driven by 3,375 customized actuators and stepping motors that moved the blocks back and forth according to a specially prescribed program. The high-speed data transfer program constantly reconfigured the cubes to create a mesmerizing show.
For those of us who have been glued to the television all week watching the London 2012 Olympics, here’s a little quiz to do during commercial breaks. According to modern Olympic tradition, the host country for the Games is responsible for creating an emblem to be used on promotional materials, by sponsors of the Olympics, and on the uniforms of every Olympic competitor. Over the decades, these logos have integrated the cultural symbols and patterns, national colors and artistic styles of the host country into the design. See if you can name the year and location for each of these emblems. A bonus point if you can recite the Olympics motto. Click “Read More” for answers.
Korea’s largest retail chain, Emart, found that slumping sales at midday were casting a shadow over its revenues and came up with a clever way to attract lunch-time shoppers. At its 38 locations throughout Seoul, Emart installed three-dimensional QR codes on outdoor pillars located to catch the sun. Like a sundial, the shadows on the QR code moved as the sun changed position, and passersby were alerted that they could only read the QR code’s message between 12 noon and 1 pm. Consumers who scanned the code were directed to the Emart online store where they received $12 coupons for products that would be delivered to their homes. Thousands of consumers claimed Emart vouchers, and sales increased by 25% during the lunch hour.
Up until now QR code technology has seemed more gimmicky than practical. Holding your smart phone up against a QR matrix on a magazine page or a storefront window to reveal the secondary message feels like a bothersome extra step that quickly grows tiresome.
But here’s a QR use that promises real convenience and time-savings. Tesco Homeplus in South Korea opened virtual supermarkets in subway stations, permitting commuters to use their smart phones to make grocery purchases. Designed by Cheil ad agency in Seoul, wall-size displays along the passenger waiting platform simulate the experience of shopping in a real supermarket, showing images and prices of a broad range of frequently needed products. Shoppers merely have to scan the QR code of any product they want to purchase to add it to their online shopping cart. The transaction is all completed online and the purchased items are delivered straight to shoppers’ homes.
