Former Apple employee and human interface developer Bruce Tognazzini published a blog post earlier this week listing his thoughts on the iWatch, a potential Apple product that made headlines late in 2012. The Pebble SmartwatchTognazzini's post encompasses a wide range of ideas on the design and functionality of the iWatch. He believes that an Apple-branded smart watch would have few standalone operations, instead being used to extend the usefulness of existing Apple devices by enhancing apps and other functions. One of his more compelling ideas includes the elimination of passcodes. With a passcode, he speculates, the smart watch, which would incorporate a sleek, button-free design, could be used to unlock iPhones and Macs via proximity. Along with facilitating phone calls and incorporating sensors, Tognazzini believes that an Apple iWatch might also include NFC capabilities for making payments and temperature controls, similar to the Nest. An iWatch could even potentially serve as a fix for Apple Maps, utilizing pressure data from watches to build an altitude map of the world, which would improve the functionality of Apple's 3D mapping. Tognazzini believes that via apps and design, Apple would revolutionize the smart watch industry, with its curved glass designs created by Jony Ive, Siri integration, and wireless charging. Though Tognazzini admits to having no insider information, he points out that his ideas come from a "solid understanding of Apple, its products, the problem, and the opportunity." His full rundown on the potential Apple iWatch is worth a read, and it can be found on his blog, AskTog. Article Link: Former Apple Human Interface Developer Speculates on Future 'iWatch'
