BYOD – Bring your own Data. Self-Tracking for Medical Practice and Research

“Facebook would never change their advertsing relying on a sample size as small as we do medical research on.” (David Wilbanks) People want to learn about themselves and get their lives soundly supported by data. Parents record the height of their children. When we feel ill, we measure our temperature. And many people own a bathroom scales. But without context, data is little meaningful. Thus we try to compare owr […]

There is no privacy in mobile

There is no privacy in mobile

Our phones register in radio cells to route the calls to the phone network. When we move around, we occasionally leave one cell and enter another. So our movements over leave a trace through the cells we have been passing the course of the day.

Sharing Goods And Sharing Data: Both Is Fun, Big Business And A Social Responsibility

Around 2010, Lisa Gansky coined the term Sharing Economy, or Mesh companies, offering their customers efficient shared access to their products instead of selling their products to them.

Global Sleep Patterns

Global Sleep Patterns

Sleep is one of the most interesting aspects of life: during sleep we don’t act consciously (apart from a few natural processes inside our body) and therefore some people try to minimize sleep to get most out of their lives.

(Jean Cocteau) Our time is perhaps the time of an epidemic of things. (Tristan Garcia) I […]
