It seems that the uptake of new “wearable digital technology’ like Google Glass or the Samsung Smart watch is not as good as manufacturers may have hoped for.
One reviewer on the net wrote about 7 days of using Google Glass for any task that it could execute.
Some interesting points emerged like
The wife factor – his wife refused to be seen in public with him wearing his Google Glass
Lack of security – if lost all info was available to the finder of the glasses
Limited power – only about 20 minutes when turned on
The need to connect to the Internet via an Android phone as the data connection (so no good it you are an Apple user)
Poor voice recognition (that is the main way to communicate with it) affected by accents and other things.
I predict the challenge of getting adequate power to these devices will be solved quite quickly and lead to a whole new range of small highly efficient power solutions.

That aside, others predict the wearables industry to be worth $18 billion by 2018. The health & fitness markets are primarily leading market Growth.
And following on from Google Glass and a Diabetes monitor that Google developed using tears, they have filed for patents for Google contact lenses. These are expected to be some years away yet but could have application for blind people as well as normal contact wearers.
