Identity iconography

Face recognition is the killer feature for Google glass and similar camera-equipped wearable computing & augmented-reality devices.

The vision is to overlay summarised personal information for the individuals in your field of view.

Privacy concerns (*) to one side, one of the major problems that these systems will come up with is the ability to effectively summarise the vast amount of information that is available about people into an easily-digestible form. Developing a suitable iconographic visualisation that summarises relevant aspects of personality & identity into an easily-digestible visual representation is going to be a significant UX challenge.

Something visually similar to (but representationally richer than) a radar (spider) chart may be required.

I can imagine a police heads-up display that places icons above individuals' heads that indicate if the individual has communicated with or has social connections with known criminals or subversives, if he has read any material that promotes crime or criticises authority, or has recently been in the vicinity of a location where a crime was reported.

Equally, I can imagine a marketing/sales heads-up display that overlays iconography that provides the ability to estimate net worth, current available funds, and emotional state (How successful various methods of persuasion might be).
