Personal Head Mounted Display
Olympus has created a prototype head mountable display (HMD) that is desgined to be worn all the time (only 27 grams in weight) and display information without hindering the vision.
They give an example of train timetables that are projected onto the users glasses.
From a mobile perspective the user should be able to see:
Call & alert notifcations
Caller ID display
No idea on cost & if it supports graphic displays such as pictures & videos though…..
