For example, the notion of privacy is very different in a family than it is in a workgroup. Knowing where your children are, and that they are safe and secure is part of the ‘job’ of being a parent. In a sense, it is part and parcel of home life. However, having access to the location and activities of your employees at work is a very different thing and may be viewed much more negatively. What is right and what is wrong is defined differently in different contexts. How human values play out in relation to computing innovation will also become more critical as researchers come up with ever more ingenious and potentially intrusive ways of sensing, monitoring, collecting and sharing digital information. Importantly, we need to consider both the positive and negative aspects of the possibilities afforded by new technologies and software. For example, a recent innovation is turning mobile phones into swarming surveillance systems, through the development of software that uses BlueTooth to automatically collect and share information between phones and then collectively analyse the events that they record. On the positive side, such a technique may provide a good way of spotting wildlife in the savannah but, equally, it could be employed for more sinister activities, such as packs of school children using it to persecute and bully each other in more insidious ways. It is important, too, to consider how the uptake of technologies is transforming our value systems. In our increasingly connected world, our notions of what it means to live on one’s own, to be part of a family, to be a teenager, and to grow old are all changing as a result of how we use social networking tools, home entertainment systems, health monitoring systems, mobile communication technologies, and so on. An average teenager now has over sixty friends. But what does it mean to create, maintain and lose friendships through digital technologies? How trustworthy are friendships made and maintained through websites? Is a teen with many online friends in fact more isolated than someone who has two close friends living next door? If we design ever more tools for communicating and staying in touch how will this affect the way we live? The new technologies allow new forms of control or decentralisation, encouraging some forms of social interaction at the expense of others, and promoting certain values while dismissing alternatives
