Heart Monitoring Glasses

Although lots of wearable displays have been coming out lately, most make you look somewhere between clueless and insane. Finally, we’re starting to see some (that are past the concept stage) which are both a wearable display and are somewhat discrete. This particular model is for athletes, and displays the heartbeat and a stopwatch in the corner of the glasses. Hopefully more heads up displays will move towards less obtrusiveness while still being useful.
