Lumus was showing off two different types of wearable displays, the development kit -- or DK-32 shown above -- and the PD-18-4 a monocular version using the same technology.
When she got horribly lost walking the simple 100m route from her hotel to my flat in Beirut last week, she laughed when I suggested cruelly that her monocular situation must have meant she was walking round in circles.
