Here are a few highlights:

• "Data collected via Google Glass could soon be used to deliver advertising tailored to the wearer's taste, mood, and location"
• "PND is developing a "personal neuro device" that gathers information on the wearer's moods, emotions and health. This data could be used by advertisers to target wearers of Google Glass head-mounted computers. When combined with the geolocation features built into Glass, the devices could work out how wearers feel about brands they are engaging with"
• "Google doesn't allow staff or partners to mention the potential use of Glass for advertising. But the device could "absolutely" be used for that purpose."

Will Google Glass still have a huge potential if people start thinking they are a sort of spycam that give access to them to every advertisers in the world?
