3RDiTEK (I'm guessing "3rd eye tech", but who am I to wonder how to pronounce unusual site names) is a sort of a headband camera that can easily record all of the events of your life.

The 3RDi "Third eye" is a techwear device that allows you to enjoy your present moment while capturing it, with its amazing HD camera, the 3RDi captures videos & photos just like an action camera.
With the 3RDi HD autofocus camera & wide view angle you can capture any moment easily, it permits you to focus on what you are doing without missing a thing.
I thought this device seems like a rather direct implementation of a lifelog, which concept was used stylishly by Charles Stross in his recent novel Halting State
You shake your head and climb out of the car, tapping your ear-piece to tell your phone to listen up: "Arriving on SOC, time-stamp now. Start evidence log." It's logging anyway - everything you see on duty goes into the black box - but the voice marker is searchable. It saves the event from getting lost in your lifelog.

The life recorder from Roger Zelazny's 1966 novel The Dream Master is an earlier reference to this idea in sf.
