Wearable Computing: Meeting the Challenge
Woodrow Barfield · 2015
Wearable computers and head-mounted displays (HMDs) are in the press daily. Why have they captured our imaginations now, when the technology has been available for decades? While Fitbit’s tness tracking devices are selling in the millions in 2014, what prevented FitSense (see Figure 2.5) from having similar success with such devices in 2000? Since 1993 I have been wearing a computer with an HMD as part of my daily life, and Reddy Information Systems had a commercial wearable with Reection Technology’s Private Eye HMD in 1991 (Eliason 1992). Yet over 20 years later, Google Glass is generating more excitement than any of those early devices.
