This week saw the launch of the Apple Watch, one more product in a growing number of “smart” sensor rich devices that promise to make life easier and better by monitoring user behaviour. Will the Apple Watch be a game changer among these devices? Technologically, the only really new sensor included in the watch that wasn’t already in smart phones appears to be the LED based heart rate sensor, which for some reason is receiving relatively little attention in the popular tech magazines. The Apple marketing machine, however, may prove to be a game changer in terms of popularity of such devices. What might the consequences be if wearable, sensorized, tech truly does become the next big consumer trend?
