Augmenting the World

• Hypertext allows us to augment information with more information.
• For example, Wikipedia augments articles with links to more articles.
• Pre-recorded guided tours augment museums.
• Now we can customise the user experience.

Concern 1: Privacy

Consider walking past a vending machine and seeing a customised advert for a drink you like.

• We give up privacy of our spending habits in return for discounts through loyalty cards.
• Should that data be sold on so that vending machines advertise what it knows I like?
• The vending machine can advertise any drink it stocks so a filter has to be applied - where? On the vending machine or on the handset I'm carrying?
• The latter offers better privacy but is more demanding of the handheld device.

Concern 2: Context

I like computers and beer. Where does this matter?

• Many of us segregate our social graphs. A typical split might be: professional (LinkedIn), personal (Facebook) and public (Twitter).
• Which, if any, do we share so that an appropriate AR stream is shown on a tablet computer?
• Again, maybe the handset is the place to apply contextual filtering for information relating to computers or beer.

Concern 3: Recognising Individuals

Walk past somone in the street. Your head up display shows you their name, likes and dislikes, favourite sports team and so on.

• Saves you not remembering his name.
• Massive use of data that was published for a very different reason in a very different context.
• Should we consider privacy tags?

Identity Control

All comes down to your identity and who controls it.

• Should we take control of our data and sell it back to the grocery store?
• Right now an AR stream might take my spending habit information and augment a picture of my house...

• Should we take control of our data and sell it back to the grocery store?
• Right now an AR stream might take my spending habit information and augment a picture of my house with a pile of beer cans on the roof.
• Is data privacy a right? Do we have an obligation to make data about ourselves publicly available?

Paper Trail

• As I react with an AR stream, who owns that contextual data?
• If I walk into a restaurant here does the augmented reality count of British people that frequent that restaurant increase?

Final Concern: Enhance, don't Detract

• Don't 'enhance' an image of the Eiffel Tower with a clip from Disney's National Treasure 2.
• Don't clutter my first view of the Mona Lisa with 50 balloons with hyperlinks to articles about it.
• Information about a given item or location will continue to grow - good - but it needs to be filtered if it is to augmnet and not overwhelm.
