When Don Draper met wearable technology

EVEN before wearable technology gains widespread popularity, advertising companies are devising ways to deliver marketing messages directly to people who don watches, glasses, and headgear that double as computers.
Case in point: InMobi Pte, a maker of mobile-ad tools, has a team of developers creating virtual mock-ups of ads on smartwatches, head-mounted displays, and other gadgets to get a feel for how they can serve as a platform for marketers. The engineers, surrounded by powerful computers with large monitors at the company’s offices in San Francisco and Bangalore, India, are trying to get a headstart in the nascent market, which has captured the attention of Google and Apple.
