Bruce Tognazzini, Apple employee #66 and founder of Apple’s Human Interface Group, published his thoughts on a potential smart watch product from the company (via MG Siegler) yesterday. While we have seen the launch of several Bluetooth smart watch products from startups this year, Tognazzini thought a watch from Apple could “have a profound impact on our lives and Apple’s fortunes.” One of the many interesting ideas Tognazzini has about how Apple might take advantage of a wearable device is the ability to build better maps:
Using pressure data from millions of watches, Apple could build a precision altitude map of the world. This map would indicate true altitudes everywhere that iWatch wearers travel. The granularity would be several orders of magnitude greater than ever before attempted for a wide-area map at a cost several orders of magnitude less than Flyover.
In the article, Tognazzini explained what he thought will be the standout features of an iWatch from Apple. While outlining the some of the apps you might expect like fitness and remote control applications, he said Passcodes and enhanced Find My iPhone features would be the two killer apps:
