GamerZines: 1UP has reported that Microsoft has registered a new patent which details the potential of using real world physiological characteristics to create avatars. The new generator would utilise, "a physiological characteristic of the user, injecting a degree of reality into the capabilities or appearance."
Microsoft will harvest the necessary information through a "third party health data collection repository, a health care smart card, a real-time physiological sensor (e.g., blood pressure, heart rate, blood glucose, peak flow, pedometer, etc.)." In order to, "avoid the inconvenience or unaccountability of voluntarily supplied information."
This proposal doesn't sound too radical in itself, after all it could be used to determine accurate skin and hair colour etc. It's not until you read what Microsoft propose to do with the information that it becomes slightly more sinister
